Cattle Guards from Barn World

Cattle Guards allow easy access to farm and ranch land by eliminating the need for gates. They give free and open access through fence lines but keep livestock contained inside. All of our cattle guards are constructed with heavy wall steel pipe and extra thick steel channel supports. The ends are capped to prevent rust and wings and boxes are available with all sizes.

Cattle Guard Types

There are two main categories to compare: round and flat top rail. The round rails are the most aggressive animal deterrent as they have round tops to prevent flat hooves from balancing. The drawback is that they create a rougher ride for high-speed vehicles.

The flat-top rails guards have slightly smaller rails spaced a bit further apart and are still very effective with cattle. They also provide a smoother vehicle crossing but are a bit more expensive.

Either is a great option for containing cattle and we’ve reviewed some more details between the two below.

Round Top Rail Cattle Guards

This is probably the most common for private property use such as driveways, pastures, and even remote areas such as cell phone towers and oil wells. They’re more economical than the flat and provide a strong cattle barrier.

They’re available in a boxed and removable box design. These two features allow it to be placed directly on the ground without digging a vault or pouring cement footings! The steel skirt, or box, goes around the perimeter to keep dirt from creeping in beneath the top rails.

The removable design allows the center grid of rails and channels to be removed without disturbing the surrounding site  Very handy in high debris areas where frequent cleanings are needed.

Boxed style cattle guard Options

Boxed styles are designed to lay directly on flat ground with a gravel under-lament recommended for drainage from the site. The box is a great option and is very popular for areas that don’t require foundations or vaults. These include lower traffic and remote or private uses. In all cases, be sure to consult with a contractor who is familiar with soil conditions including drainage, freezing levels, and any local building codes.

Flat Rail Cattle Guards

The flat style is designed to be mounted on cement footings and is the most popular in high traffic, high-speed areas such as public roadways. They are bolted directly to the concrete footings which come with pre-embedded j-bolts for anchoring. This setup is extremely convenient for those who don’t want to pour their own foundations or can’t get cement to a remote area economically. You can unload them from the truck and put them directly in place.

The flat-top rail guards have an optional hinged area that allows the center section to be tilted up and away. This allows for easy access beneath the rails for cleaning out debris underneath. It’s not available on all guards, but may be included with the flat top rail designs.

General Cattle Guard Notes

Here are some general notes and guidelines to help with the selection of the right type for your installation.

Load Ratings

All of our cattle guards can withstand the weight of full tractor-trailer loads. The private use of round rails is the most economical and popular for private property such as driveways and farm entrances.

The American Association of State Highway Transportation Officials (AASHTO) provides guidelines for cattle guards with maximum load ratings. The load ratings are suitable for all types of applications including heavy-duty logging roads. (See the table at the bottom of this article for more details on load ratings.)

AASHTO Design Specifications

  • H-15 (12 tons per axle)
  • H-20 (16 tons per axle)
  • U-54 (25 tons per axle)
  • U-80 (30 tons per axle)

Rated cattle guards will meet the specifications needed for state and federal requirements such as DOT, BLM, USFS, NP, and US Military installations. They are also used in commercial applications such as mining, forestry, agriculture, and petroleum production. Rated cattle guards are the product of choice for residential usage where city, county, or state regulations require the HS-20 rating. Certified structural steel is used in the manufacture of HS-20-rated cattle guards.

HS-20 cattle guards will be certified by an independent engineering firm to meet commercial standards and are intended for government bids. For use on private land, buying standard cattle guards will save you thousands of dollars, are identical in size, and are made out of the same materials. They just do not come with the certifications and paperwork back to the steel mill that government agencies require. If a non-rated guard for a private drive is needed, use a standard cattle guard.

Cattle guards may be constructed with 3″, 3-1/2″ or 4″-1/2″ pipes.  The 4″ pipe allows for an approximate gap of 4″ between each pipe and is built with 9 pieces.  The 3-1/2″ outside diameter pipe guards have 11 pieces and are approximately 12-1/2″ tall.

There is no difference in strength between the boxed cattle guard and the flat styles of cattle guards.  These cattle guards are designed to accommodate full semi-loads at 10 tons per axle.  All cattle guards weigh about 100 Lbs. per foot (a 10′ cattle guard weighs about 1,000 Lbs.). Add approximately 8 Lbs. per foot for boxed cattle guards and about another 200 Lbs. total for winged cattle guards.

Using Cattle Guards with Deer

To use with deer, you may need to place two cattle guards in tandem so you have 16 feet of protection. Cattle guards are easily bolted together to achieve greater distances in the direction of travel and create a larger deterrent for any animal wishing to attempt a jump. Please note that we recommend standard gates be used when containing horses, goats, all small hoofed and sure-footed animals, and animals with paws.

Ordering your cattle guard:

For a shipping quote, please send us an email with your destination zip code and quantity, or feel free to call the telephone number at the bottom of this page with any questions you may have about our cattle guards.

Delivery:  Due to their large sizes and weights, you will need to have unloading equipment available upon delivery. The driver won’t be able to remove the guards or foundations from the trailer.

Dimensions: Private use cattle guards are NOT built to exact dimensions. Sizes may vary slightly and adding the removable box option will add about 7″ to the overall length and width.

If you have any questions, would like a quote with shipping or if we can help with anything at all, please don’t hesitate to contact us.  We’ll be glad to assist in any way we can. | (720) 238-2190 |


Cattle Guards and Livestock Management

Cattle Guards offer livestock containment and peace of mind

Owning and running a ranch is a full-time job. It’s a 24-hour labor of love to raise and care for many animals at a time. Moving around to feed and attend to your livestock requires access to pastures that must be able to contain and protect while allowing ease of access for equipment and vehicles. A cattle guard is the perfect solution and they come in many different shapes and sizes to allow for most any type of use.

We do not recommend a cattle guard be used for all types of animals.

Horses and Small Hoofed Animals:

For some animals, these barriers just don’t work and can sometimes put them in harm’s way. Goats and other small, sure-footed creatures, can trot right across the top of the rails. Some larger animals like horses have slender hoofs that can present danger with possible dire consequences.

It is possible that some horses can slide their hoof between the top rails and into the vaulted area beneath. This can expose the most delicate and fragile part of the leg to the steel rails on each side. Once in the guard, it is extremely, if not impossible for them to get out. They will most likely try, become full of panic, and can break their leg in the struggle.

We strongly recommend only using a gate to contain horses.

Cattle Guards and Deer
Deer are agile creatures with small hoofs and incredible athleticism. The installation requires a modification to be an effective deterrent.

Their ability to effortlessly jump large distances means that distance needs to be increased to be effective.  We typically install at least a 12-foot barrier, with 16 feet being an ideal distance to discourage them from jumping across. To get that kind of depth, two guards are bolted together, side-by-side to double the width of the ‘Texas Gate’. Seeing the larger distance will persuade them to find another direction to travel.

Cattle Guards and Non-hoofed Animals

The working mechanism of the grid is the curved surface of the top rails.  The hoof is flat on the bottom and when placed on a curved surface, it acts like a teeter-totter and doesn’t allow the animal to balance. This uncomfortable and physically challenging surface means they can’t put any weight on their leg. That, along with the limited depth perception in cows, provides a strong and seemingly impossible barrier to hoofed animals.

Those with padded feet, however, can balance on the rounded pipe as their point of contact is flexible. The ability to stand on a small curved surface allows them to balance and walk on the very tops of the rails

This means the guards are not very effective in keeping out dogs, cats, coyotes, and other ‘soft-footed’ four-legged friends. They’re able to walk across and only a gate would be able to stop them.

Types of Cattle Guards

Barn World offers several types of cattle guards for both private and public use.

Private use cattle guards are perfect for farm and ranch use and for access areas where the total axle weight is up to 10 tons. Semi-trailers, tractors, and large farming equipment are perfect for this type of guard.

They’re more economical than the flat top guards and provide a more aggressive livestock deterrent.

Round Top Rails

The round rail is very popular across the US and especially for private land use. It’s more economical and can be easy to install. Concrete foundations are always recommended as is a flat but well-drained site. They’re available with a few different options depending on the type of installation desired.

These include the skirted grid for installation directly on the ground (Boxed) as well as wings and even a removable box design.

Boxed style cattle guards

Not all installations require a foundation for the grid to rest on. This skirted style can be set directly on the ground and the welded on perimeter box keeps dirt from coming in below the top rails. Most private users will dig a hole with a gravel base for drainage so the 12″ tall guard is about 2″ above the road surface.

For more stability, especially if the site is not perfectly flat, burying a couple of railroad ties to bolt to can help reduce any walking and offer the security of being ‘tied to the ground”.

A gravel base is recommended for proper drainage so the steel skirt welded to the outside won’t’ hold water and compromise the surrounding soil.

In many cases, the boxed design is used for construction site equipment wheel washes or rumble stripes to remove dirt before re-entering a roadway. They can also be picked up and moved to the next job to guard against tracking unwanted debris.

The Boxed Cattle Guard

All of our cattle guards can withstand the weight of full tractor-trailer loads and are typically made with 3 1/2″ or 4 1/2″ outside diameter pipe. Depending on the size used, they are made with either 9 rails of 4 1/2″ or 11 rails of 3 1/2″ outside diameter pipe and are approximately 12-1/2″ tall. There is no difference in strength between the boxed cattle guard and the flat styles of cattle guards.


Each completed grid weighs near 110 pounds per foot (a 10′ cattle guard weighs about 1,100 Lbs.). Add approximately 8 pounds per foot for the addition of a box and near another 200 pounds in the total weight for a pair of wings. To use for deer, you may need to place two cattle guards in tandem so you have 16 feet of protection. Cattle guards are easily bolted together and the extra depth can help deter deer from crossing or jumping.

Important Delivery Notes:

  1. You must have equipment available to unload the cattle guards from the delivery vehicle when it arrives. The delivery truck will require you to unload the cattle guard with a loader or forklift or some other means upon delivery.
  2. Private use cattle guards are NOT built to exact dimensions and sizes may vary slightly.  Adding the removable box option will add about 7″ to the total length and width of the cattle guard. For example, a 12-foot cattle guard will be about 12′-7″.

ATV Cattle Guard

We also carry a unique cattle guard design for ATV use. It’s built to be set directly on the ground in your fence line. You may simply cut your fence, set the guard in place, and reattach your fence to the size of it to provide easy access to your all-terrain vehicles. atv cattle guard
