Cattle Guard Use
Barn World cattle guards allow easy access to farm and ranch land by eliminating the need for gates. Cattle guards give open access but keep livestock inside. All cattle guards are constructed with heavy wall steel pipe and extra thick steel channel. All ends of these cattle guards are capped to prevent rust. Wings and boxed cattle guards are available with all sizes.
Cattle Guards and Different Styles
Boxed style cattle guards
Boxed styles are designed to sit on flat ground with a gravel under-layment recommended for drainage of these cattle guards. In many cases these boxed cattle guards are used for wheel washes in construction sites, dirt rattlers and for providing access to low or slow traffic sites such as cell phone towers, off-site construction, driveways and other low traffic areas. In all cases a local contractor familiar with soil conditions and drainage considerations should be consulted when planning an installation.
Flat Style Cattle Guards
The flat style is designed to be mounted on cement footings and is the most popular in high traffic areas such as public roadways. They are bolted directly to the concrete footings that also create the ‘vault’ or empty space under the guard. This provide a visual deterrent to animals and is very effective in dissuading and attempt at crossing.
The flat style is a permanent installation and some designs have a hinged area on the guard that allows the center section to be lifted for cleaning out debris that may have collected in the vaulted space area underneath. This feature is not available on all guards, but may be included with most of the highway rated crossings.
General Cattle Guard Notes
Here are some general notes and guidelines:
All cattle guards can withstand the weight of full tractor-trailer loads. The non-rated are most popular for private property such as driveways and access for farm equipment.
The American Association of State Highway Transportation Officials (AASHTO) provides guidelines for cattle guards with maximum load ratings. AASHTO 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 AASHTO 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 HS20 rating. Certified structural steel is used in the manufacture of HS20 rated cattle guards.
HS20 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 all the way 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″ pipe. The 4″ pipe allows for an approximate gap of 4″ between each pipe and be 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.
Extending the depth of deterrant
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 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.

Note: 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 fork lift or some other means upon delivery.
Note with regard to dimensions: Private use cattle guards are NOT built to exact dimensions. 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″.
