Metal Grain Bins

Galvanized Grain Bin Advantages Over Poly

Grain and Feed management requires a reliable and durable storage solution. For those seeking top-notch quality and functionality, look no further than the bins at, your go-to destination for high-quality metal grain bins and customer service. Our last Poly Grain Bin Blog Post contrasted the advantages of the poly design over metal, and in this one, we’ll explore some of the advantages of galvanized feed bins over poly. Some of these include more available sizes, capacities, and some innovative dispensing and monitoring features not found on poly grain bins.

When it comes to choosing the right material and features for your grain storage needs, deciding on a bin really depends on your opinion, the type of dispensing, durability, and longevity that make up a complete grain bin management system. We review some of the benefits of the Metal Grain Bins below.

Rust Worry can be overblown – steps to protect a metal bin:

One of the biggest advantages of the Poly Bin over the Metal is the worry about rust affecting the life of the bin. Although poly material won’t ever rust, steel will resist rust and corrosion for a long time, ensuring that your investment stands the test of time even in the harshest weather conditions. Bins that we sold 20-30 years ago are still in great shape and in use today.

Preventing rust on a galvanized metal grain bin involves proactive maintenance and care. While galvanized steel is known for its rust-resistant properties, external factors and wear over time can still contribute to corrosion.

Here are some steps to help you prevent rust and prolong the life of your galvanized metal grain bin:

1. Regular Cleaning:

Keeping your bin free of dirt and debris will keep moisture away from the metal and minimize the chances of rusting over time. To keep moisture away, rinse the surface of the grain bin regularly with clean water to remove dirt, dust, and other contaminants. Use a mild detergent or a mixture of vinegar if necessary with water to clean stubborn stains or deposits. This is not an easy task and can take some time if a bin is neglected. The shape of the corrugated wall sections can make this a bit more challenging, but making sure it’s free from dirt and dust will dramatically increase its lifespan.

2. Remove Standing Water:

Ensure that water doesn’t accumulate or stand around the bottom of the bin. Standing water can promote corrosion and result in rust. Bins can require frequent replacement of the bottom attachments such as slide valves and auger unloader boxes if moisture is allowed to accumulate at the lowest point. Even the hopper wall sections can be susceptible to rust if moist grain or feed is allowed to lay on the interior wall sections.

Proper ventilation through the bin lid and good air circulation throughout can help prevent moisture buildup inside and reduce the risk of rust formation. The metal bins, like the poly bins, are vented through the top lid to help release moisture as it rises. It’s important to keep these vents clean, clear, and open so any water vapor that rises won’t be contained within and will naturally be released through the top lid.

Another suggestion to keep moisture at bay is to trim or remove vegetation from around the bin to prevent water or condensation retention. It’s worthwhile to create an open buffer of air between the metal surfaces and any plant material to prevent condensation from forming.

3. Inspect and Repair Damages:

Regularly inspect the grain bin for any scratches, dents, or damage to the galvanized coating. Scratches through the galvanized coating expose the steel to the air and water and can be areas of potential concern. Promptly repair any scratches or damaged galvanized coating by applying galvanized touch-up paint. It’s fairly commonly found at hardware stores and the like.

A simple and short visual routine inspection to identify any potential issues will help eliminate long-term problems early on. This includes checking seams, joints, and connections for signs of wear or damage.

4. Avoid Harsh Cleaning:
Avoid using harsh chemicals or abrasive cleaners, as they can damage the galvanized coating. Scaping or scouring the metal can remove the protective coating and expose the underlying metal. It’s best to stick to mild solutions and softer wiping, rather than scouring for basic cleaning.

5. Maintain the Protective Coating:

As you may have gathered, the galvanized coating over the metal surface that covers the bin walls and parts (nuts and bolts, etc.) is what protects the underlying steel from rusting. It’s important to maintain its integrity to extend the life of the bin. The suggestions above do just that but if you come across damage to the coating, there are protective sprays and paints designed to repair galvanized surfaces that may be applied. These coatings will add a layer of protection against corrosion and prevent premature rusting throughout the bin.

When making repairs or modifications to the grain bin, use galvanized fasteners and hardware to maintain uniform corrosion resistance throughout the structure. You should also minimize direct contact between galvanized metal and other metals that may cause galvanic corrosion. It’s beneficial to use isolating materials such as rubber washers or coatings when necessary to avoid cross-corrosion between parts.

6. Proper Installation:

The robust nature of galvanized steel provides increased structural integrity, safeguarding your valuable grain against external elements and pests. However, it’s important to ensure that the grain bin is installed according to manufacturer recommendations. Proper installation can prevent stress points and other cracking or structural issues that may lead to corrosion.

By incorporating these preventive measures into your maintenance routine, you can significantly reduce the risk of rust on your galvanized metal grain bin and extend its lifespan dramatically.

Regular attention to cleaning, inspections, and prompt repairs will contribute to the long-term durability of your grain storage investment and should put any concerns of an early demise from rust to bed!

More sizes and Capacities Than Poly bins understands that one size does not fit all. Our metal grain bins are available in a range of sizes and capacities, catering to the diverse needs of farmers and agricultural businesses. The bins are available as small as 2.7-ton capacities and go all the way through 47.5 tons of capacity. This compares to the poly bin maximum of 28 tons.

Whether you’re a small-scale farmer or managing a large operation, you can find the perfect fit for your grain storage requirements through a wide variety of storage capacities in galvanized metal.

Hopper Valve Option available for Side Dispensing

One standout feature that is available on metal bins but not poly is the side-mounted slide valve. It’s a manual slide gate designed to mount to the tapered hopper walls to fill smaller quantities, such as 5-gallon buckets, with precision and ease. This innovative design allows for controlled dispensing from the side of the bin, so you don’t have to go under it to fill containers. It makes it easier on your back and minimizes waste. It’s extremely popular and may be seen and ordered here:  Hopper Valve

Grain Bin Monitors are available for metal bins

Monitoring feed levels is crucial for efficient grain management. offers a cutting-edge solution with the Grain Gauge, ensuring you always know how much feed is in your bins. This simple yet effective tool eliminates guesswork, allowing you to plan and manage your resources more effectively.

The installation is straightforward; simply drill a hole in the bin wall and slide in the gauge. It will display a neon green color if the grain is at the level of the gauge and go black when there is no feed at that level. There is no electricity required and the manual function will last for years. Don’t pound on the side of your bin to check the fill level, simply glance at the side of it for an accurate level.

Poly Grain Bins

Poly Grain Bin Advantages Over Metal Feed Bins

In the ever-evolving world of agriculture, the quest for efficiency, durability, and innovation is a constant endeavor. One significant leap in this journey is the adoption of polyethylene feed bins over traditional metal grain bins. In this blog post, we’ll explore the compelling reasons why poly feed bins stand out as the superior choice for storing and managing feed and materials.

small poly grain bins large poly grain bins

Corrosion Resistance: The Achilles Heel of Metal Bins

Metal bins have long been a staple in feed storage, but they come with a critical flaw: susceptibility to corrosion. The relentless exposure to varying weather conditions, moisture, and acidic feed components can take a toll on metal bins, leading to rust and structural degradation over time. Poly feed bins, on the other hand, are inherently resistant to corrosion. The polyethylene material ensures longevity, saving farmers from the headaches and expenses associated with rust-related issues.
With a galvanized grain bin, the battle against rust is a constant struggle. Not so with a Poly Bin. The poly material eliminates this concern and early demise entirely. The hopper wall sections of poly bins are immune to rust, ensuring the longevity and structural integrity of the storage system. This resistance to corrosion is particularly crucial in maintaining the quality of stored grains and reducing maintenance costs over time and is one of the largest reasons why farmers are moving to poly.

Lightweight yet Durable: Simplifying Storage and Transportation

Poly feed bins offer a remarkable balance between strength and weight. Unlike their metal counterparts, poly bins are lightweight without compromising durability. This not only simplifies the assembly process but also makes transportation and repositioning a breeze. Farmers can adapt to changing needs on the farm with greater ease, rearranging feed storage locations without the need for heavy machinery or elaborate logistics.

Ease of Assembly: Say Goodbye to an Overabundance of Nuts and Bolts

One of the significant advantages of poly feed bins is the straightforward assembly process. Traditional metal bins often involve an intricate network of nuts and bolts, making assembly a time-consuming and labor-intensive task. Poly bins, designed with user-friendliness in mind, use far less hardware and dramatically shorten the assembly time required.
They ship and arrive in two large, pre-cast pieces, a top and a bottom that are bolted together in the middle. There are no wall sections to assemble, and the continuous molding of the plastic eliminates seams where water and insects could enter and cause issues.
Unlike the intricate assembly process of metal bins that involve countless nuts and bolts, poly bins feature a user-friendly design that significantly reduces assembly time. This can be a game-changer for busy farmers looking to maximize their efficiency during the harvest season.

Protection for the Elements

As mentioned above, the seamless walls won’t allow bugs or water to enter the bin as an ill-fitted metal wall bin might. The metal bins have horizontal seams that should be monitored for any cracking or warping that may allow pests or moisture to enter. Poly bins don’t have seams and the rotational molding technique makes sure there is a smooth and even thickness throughout the bin walls.
The polyethylene includes a UV protection resin right in the material itself. It helps protect the walls from sun exposure and drying out. This prevents cracking and ensures a long life of the bin and the grain inside!

Translucent Walls for Visibility:

The translucent walls of poly grain bins set them apart from traditional metal bins. This feature allows farmers to easily monitor the contents of the bin without the need for additional tools or equipment. The transparency of the walls provides a clear view of the grain levels, enabling farmers to make informed decisions about inventory management and restocking. You don’t need to be banging on the side of the bin to determine how much is in it, you may simply look while walking by!

Hygienic and Easy to Clean: Ensuring Feed Quality

Maintaining feed quality is paramount for the health and well-being of livestock and other farm animals. Polyethylene feed bins have a smooth, non-porous surface that resists the buildup of dirt, bacteria, and mold. Unlike the corrugated surfaces of metal bins that can harbor contaminants, poly bins are easy to clean and sanitize. This hygiene factor not only safeguards the nutritional value of stored feed but also contributes to the overall health of the livestock.

Cost-Effective: Long-Term Savings for Farmers

While the upfront cost of poly feed bins is comparable to traditional metal bins, the long-term savings are significant. The durability, corrosion resistance, and low maintenance requirements translate to reduced replacement and repair costs over time. It truly is a cost-effective storage solution for grain management.


The shift towards polyethylene feed bins marks a pivotal moment in the evolution of agricultural storage. From corrosion resistance and ease of assembly to customization and cost-effectiveness, the advantages of poly feed bins over traditional metal grain bins are clear. As modern farmers continue to prioritize efficiency and sustainability, embracing the superior qualities of poly feed bins is a logical and rewarding choice for the future of feed storage.

The Benefits of On-Site Grain Bins for Storage

Working the land to make a living is very much a game of chance. Farmers and
ranchers are often at the mercy of Mother Nature to provide the necessary elements for profitable success.

While there’s no way to control the weather, there are certain steps farmers and ranchers can take to increase the probability that things will work out in their favor. The installation of grain bins as on-site storage solutions is an important one.

The Many Benefits of Grain Bins

In many ways, grain bins have long been a staple of farm and ranch life. As family farms work to thrive across the nation and commercial farming becomes more the standard, these storage solutions are more essential than ever before.

On-site grain bins provide a convenient alternative to working with local grain elevators and merchandisers whose prices frequently fluctuate according to demand. They also provide essential protection from the elements that farmers and ranchers depend on to keep grain in quality condition year-round.

Drying grain can be a costly and time-consuming process. Those who invest in on-site grain bins will cut down on drying time and open up options when it comes to selling in accordance with market fluctuations.

Versatile Bin Options

Traditionally, grain bins were standardized metal structures with little in the way of size variation. Today, the reality is very different.

Farmers and ranchers now enjoy a versatile lineup of grain bin options that range from durable metal structures in varying sizes to lightweight and bulk poly bins. In the modern world of farming and ranching, it’s common for a combination of grain bin styles and structures to work best for operations large and small.

Noticeable Differences

Metal grain bins are often still the preferred choice amongst consumers when it comes to long-term grain storage. The durability of metal surfacing provides the assurance that these structures will pay for themselves over the long-term. Additionally, the ability to add specialized accessories to metal bins such as stiffeners, ladders, and auger kits make it simple to customize a bin according to the needs of a farm or ranch.

Metal Grain Bins

Poly bins tend to be excellent choices for feed storage thanks to their semi-translucent façade which provides farmers and ranchers with a clear view of refill levels. Smooth poly surfaces prevent grain clogging and are far lighter in weight than their metal counterparts.

Poly Grain Bins

Farmers and ranchers will find that both metal and poly bins provide an exceptional level of successful storage whether they’re looking to place seeds, grains, or pellets. Having these options available allows for fitting your on-site storage needs to your specific land requirements.

More to Consider

The weather and the market may fluctuate but having grain bins right on-site means farmers and ranchers never have to worry about adjusting their prices to meet the demands of communal storage. It’s also important to consider the fact that access to on-site grain bins means more freedom when it comes to determining a profitable harvest schedule.

When you’re ready to install a collection of grain bins on your farm or ranch, you might even see significant benefits within your tax bracket. In many cases, grain bins can be claimed as an expense against income.

What Exactly Is a Bushel? The Question Turns People Into Basket Cases

Here’s a great article from the Wall Street Journal about the complexities of measuring and trading in bushels. We all use the term frequently when describing grain bin capacities, but when using the term to trade large quantities or set commodity prices, the actual calculations become quite involved and the quantity traded can become pretty ‘abstract’ as described in the article below.

The Winchester bushel, named for a British town, dates back centuries.

Prices of agricultural commodities are quoted that way, even though many have never actually come across the baskets; ‘kind of an abstract amount’

Soybean prices have long been quoted in bushels at the Chicago Board of Trade.

Trade tensions between the U.S. and China this year have caused gyrations in soybean prices, which recently climbed above $9 a bushel. They also have people buried in soybean math.

Prices of agricultural commodities have for decades been quoted in bushels at the Chicago Board of Trade, yet many traders and farmers have never actually come across soybeans in the quaint wooden basket that has existed for centuries.

“Most people haven’t seen a bushel basket—I never have,” said Anthony Stinton, a soybean meal trader in Greeley, Colo. Scrawled on a yellow sticky note on his computer is a formula he punches into a calculator multiple times a day to convert metric tons of soybeans grown in Brazil into their American bushel equivalent. “It’s kind of an abstract amount,” Mr. Stinton said.

A bushel of soybeans is roughly enough dry beans to fill eight gallons or 2,150.42 cubic inches of space, the capacity of a traditional bushel basket. That is the equivalent of 60 pounds of soybeans. In the Bible, bushels were used as containers for grains, seeds, and flour. At farm stands and markets, bushels can be found filled with apples, crabs, and raw vegetables. The phrase “a bushel and a peck” is fairly well-known thanks to a popular “Guys and Dolls” song. (A peck is a quarter of a bushel or eight quarts.)

In the commodities world, they are a mathematical headache. Ariel Haendler, global head of soybean trading at Chinese state-owned trading giant Cofco International, said he always carries a calculator when he attends strategy discussions with colleagues and uses it to convert metric weights into bushels. (1 metric ton of soybeans = 36.74 bushels.)

During those meetings, there is “always a 10-second break when we make these big calculations on these calculators going back and forth like we’re in the fourth grade,” said the Swiss-based American trader. Even though Mr. Haendler has the formula memorized, getting the numbers wrong could be potentially costly, he added.

To help market participants with their math, CME Group Inc., which operates the Chicago Board of Trade, has a 44-page pocket guide that includes scores of weight-conversion tables for a range of commodities.

For example, it recommends that to convert 11,000 metric tons of soybeans to bushels, users can simply add the conversions for 10,000 metric tons (367,437 bushels) and 1,000 metric tons (36,744 bushels) to get a total of 404,181 bushels of soybeans. Each soybean futures contract is made up of 5,000 bushels.

On the Scott family farm in Delphi, Ind., there isn’t a bushel to be found. “It’s just an idea in our head,” says Brian Scott, who grows soybeans with his father and grandfather along with corn and wheat. “We think in bushels but they don’t measure in bushels,” he said.

Instead, trucks are filled to the brim with commodities and sent to a depot to be weighed before the produce is sold to trading firms. ”When you deliver, they measure in pounds,” Mr. Scott said, noting they give a receipt with a bushel measurement too. One truckload of beans weighs roughly 1,000 bushels, he says.

America remains an outlier holding on to the old imperial, or U.S. customary system, of pounds and acres when the rest of the world has largely shifted to the metric system of kilograms and hectares. Other countries that use the imperial system include Liberia and Myanmar. In addition to bushels, the U.S. also uses pecks and lugs, which are wooden boxes of no standard size.

Traders say the challenge with bushels is that they are a measurement of volume, so the weight of whatever is in it varies depending on the commodity. While soybeans and wheat weigh roughly the same, corn is slightly lighter.

“If I take the price of Chicago wheat and I want to know what it means for the rest of the world, I multiply it by 36.7437,” said Chris Bird, a senior global wheat trader at Engelhart Commodities Trading Partners, without missing a beat. As he has to do the conversion 20 or 30 times a day, “I have it set up on my screen to do it but honestly, I could almost do it in my head,” he added.

He wasn’t so quick with commodities he doesn’t trade. “Corn is 39 something-something-something…” Mr. Bird said. “It’s very random.”

There’s also confusion between Canadian and U.S. bushels, which have different capacities. The latter is also known as the Winchester bushel—named after a British town—first mentioned in law in the 17th century and was defined as a barrel that is 18-1/2 inches wide and 8 inches deep. The measurement was abolished by the English in 1835, a year before the U.S. Department of Treasury adopted it as a unit of measure.

The Winchester bushel, named for a British town, dates back centuries.

FarmLead, a Canadian-based online marketplace for soybeans, wheat, and other commodities trades, has a calculator on its website for customers to convert pounds, tons, or other measures to American bushels. The soybeans currently for sale on its site are stored in a flat bottom bin.

Before deals are done, people often need to “scribble out their math” or “double-check the conversion” to make sure buyers and sellers are talking about the same amounts, said Alain Goubau, the company’s chief operating and financial officer. At the end of the day, traders have little choice but to hew to the American system, he said, adding: “It comes down to—do you want to be right or do you want to do business?”

Brian Rohrig’s hog farm outside Des Moines, Iowa, sometimes uses physical bushels made of aluminum to measure soybean meal before it is mixed into feed for the pigs.

The bushel baskets are a decent volume gauge, said Mr. Rohrig, but there’s one downside: they are much heavier than a five-gallon pail. The machine his farm uses to mix animal feed now has its own weighing scale, so there is less need for the bushels, he added.

Small Feed Bin Uses

The bins allow large-size materials to pass through the manual slide valve at the bottom. This works great for managing all types of materials, not just animal feed.

Heating Pellets

A lot of homes burn pellets for heat. This includes corn and pellets designed specifically for burning in a stove. When using this system a method of storing and dispensing is made easy with the small feed bin.

It keeps the pellets or corn dry and protected from moisture and allows for manual dispensing to a bucket set under the bin.

Feeding Animals

The mini-feed bin is great for filling buckets and feeding animals by hand. It’ll also dispense range cubes as large as 3/4″ round by 2″ long.  The large locking lid opens very wide for easy filling and its smaller size makes it very manageable.


There are two different available sizes. Each bin is 5′ in diameter and the extra capacity is created by adding a second steel ring wall section. The diameter remains the same but it adds 2′ to the overall height

Dimensions and Capacities

    • 40 bushel  / 2,240-pound capacity (corn) – 5′ diameter and 8′ tall
    • 65 bushel / 3,640-pound capacity (corn) – 5′ diameter and 10′ tall


As mentioned above, the bins ship unassembled on a pallet to keep shipping costs low. We can ship them around the country and if you’d like a quote with delivery right to your door, just let us know and we’ll forward one for your review.

Metal Bulk Feed Bin Design

These heavy-duty steel grain bins are built to hold High capacities of loose material outdoors year-round. It stores and protects from the elements, pests, and rodents alike.

Below is a partial diagram of an assembled bin for review. Note the steel wall seams have overlap drip guards and won’t let water into the bin. This design culminates in a 16″ diameter opening at the bottom of the hopper sections.

This allows a multitude of attachments such as manual slide valves and motorized augers for unloading.

The waving bends in the steel walls are there to create additional vertical strength. The walls have a 4″ wide corrugation that adds an estimated  25% increase in strength over a wall without corrugation. The corrugation also creates a release point for free-flowing. The waves of the Steal reduce the downward resistance on stored material and help reduce any bridging or ‘hanging up on the interior of the walls.

The G-90 Steel

G-90 is a designation for the finish that coats the steel. It refers to the amount of zinc that remains on the material after a hot dip in zinc. The 90 means that there is a minimum of .90 oz. of zinc per square foot. This provides excellent protection from corrosion and rust and allows the bins to be used exclusively outdoors, year-round.

The bins are built by assembling them on their sides and then standing upright. A cement pad is used to anchor the legs to the ground to prevent tipping in high winds when empty.
