HS20 Rated Cattle Guards for Public Roadway Projects

Barn World offers a complete line of cattle guards engineered for public roadway projects. The HS20-rating is the required by Department of Transportation Authorities and is a 16 ton per axle engineered rating.

They are made in either round or ‘flat’ steel top rails and are available in a variety of sizes. The longest single-span cattle guard is the round top rail 20′ design.while the flat top rail is available in a 14′ length. The guards may be bolted end-to-end for projects that require an even longer distance across a roadway. This method is a simple means of providing wider access for crossing vehicles.

Some crossing require more ‘depth’, or distance in the direction of travel.  The standard is 6′ or 8′ but the grids may be set side-by-side to increase the distance. This is useful when creating a barrier for more athletic animals such as deer. The added distance provides a deterrent to them jumping the crossing.

The HS20 Rating

The rating is a engineered certification that the design will provide support to vehicles with 16 tons on each axle with an additional safety factor built in.  It’s required for all Department of Transportation projects and the designation is called out for by the AASHTO (The American Association of State Highway Transportation Officials). The rated cattle guards are certified for public works and roadway projects that adhere to the following load-ratings.

Rating Designations

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

These engineered designs that call out the details for not only the materials used, also specify how they are to be built.

Cattle Guard Wings and Foundations

The cattle crossings are also available with optional cattle guard foundations and wings if needed.

Cattle Guard Foundations

The foundations ship pre-cast and can be set directly in the ground upon delivery. They include j-bolts already set in the concrete that line up with the guard mounting holes. This allows the guard to be directly bolted and secured without the need for drilling holes in the field.

Cattle Guard Wings

The wings are available on both designs (round and flat top rail) and connect the fence line directly to the ends of the crossing. They prevent livestock from stepping around a single end post where the fence terminates. This simple, triangular addition completes the transition from the vertical fencing to the horizontal, in ground barrier.

At Barn World, we’re more than happy to help with your project from the planning and quoting stages all the way through delivery.

Cattle Guards for Livestock Containment

Cattle guards are designed to keep livestock from crossing through your fence lines while allow traffic free access without stopping. The spacing of the top rails create unstable footing and prevent cows from walking on. These top rails are available in round and flat top designs for different types of traffic and crossing speeds.

Please note that we do not recommend using these devices with horses. They have more slender hooves and legs which increases the risk of one sliding through. Once through the top rails, the leg is exposed to breaking if a struggle to get out ensures. It’s best to use a standard gate with horses.

We do have Concrete Cattle Guard Forms that have a ‘bottom’ between the uprights to the hoof can’t slide through and between steel rails. The forms are more economical to ship than traditional steel designs, can be poured onsite and are reusable. You can make as many concrete cattle crossings as you need.

If you have dogs that you want to contain, you should use a gate. Dogs have soft pads for feet and can walk across the top rails with no problem at all. Goats and sheep are also animals that require a gate to keep them going through your opening. Even though they both have hooves, they are very good at balancing and can tip-toe across the rails.

To be effective with deer, extra depth (the distance in the direction of travel) must be increased so these athletic animals don’t just jump across. This requires two cattle grids bolted together, side-by-side to create a distance of 12 to 14 feet at a minimum. You’ll also need to make sure the fencing around your property is high enough to prevent them jumping over at more remote areas.

Cattle Guard Wings

Another often overlooked part of the livestock barrier installation is the transition from the fence line to the guard itself. If the fencing is simply terminated at a post set in the middle of the guard, cows will be able to just step around the post an avoid the grid altogether.

The wings take the vertical fencing barrier and transition it to the horizontal barrier in the ground. They prevent animals from stepping around the end post and spread the fencing to each end of the guard.

How to Install a Cattle Guard

Every long-lasting building requires a solid foundation and a cattle guard installation is no different. It carries heavy loads with shifting weighs and it’s extremely important that it’s installed on a proper foundation correctly.

We strongly recommend that a contractor familiar with the local site conditions be used for a proper installation. Typical site considerations include: frost levels, drainage, type of soil and even local building codes. All of these factors are important to take into account for a long-lasting trouble free cattle guard crossing.

 

Generic Foundation Diagram

Excavation of the Vaulted Area

The vaulted, or dug-out area beneath the grid is key to providing the often overlooked optical barrier that dissuade livestock from even touching the top rails. Allowing the animal to view the bottom of the excavated area provides a conflicting depth perception created by the contrast with the top rail. This optical confusion (near and far at the same time) can be an effective visual deterrent all on it’s own.

Painted Guards

Studies shown that the illusion a three dimensional grate when painted across a roadway. and sometimes be effective at preventing crossing by itself. In the studies, cows were introduced to the fake barrier and almost all of them refused to cross initially. The trouble with the painted illusion was when one did eventually work up the courage to test the perceived barrier, it was able to walk over it without trouble. This then gave courage to the remaining livestock and they also soon followed.

The vaulted area is created by removing soil under the top rails to create the visual deterrent and allow debris to fall through. We typically recommend at least 6″ be dug below the bottom support beams as shown in the diagram. With a 12″ overall height, a depth of 18″ from the top rail to the bottom of the vault will be presented to the livestock. You may go deeper if desired, the important issue is that the foundations themselves are properly supported.

The vault also helps prevent debris from collecting between rails. If the vacant area beneath wasn’t there, dirt and debris would fill the area between the top rails and the barrier would lose it’s effectiveness and become a livestock walk-able bridge.

To help with drainage, the bottom of the vault should include a means of allowing water to drain way from the installation without disturbing the surrounding footings. Typically crushed gravel is used to create a french drain. Because every site is unique, a contractor familiar with the local conditions should be consulted.

Foundations

Concrete footings are usually poured on site but we do also offer pre-cast concrete cattle guard foundations that can be shipped right along with our flat rail cattle guards.

The concrete is designed to fit pre-drilled holes in the guard so they can be bolted down upon arrival. Quick, easy and convenient, they’re becoming a more popular option for sites that don’t want to pour their own.

 

Surface Installation with a Boxed Cattle Guard

Boxed cattle guards are set directly on the ground and are designed for low traffic, remote and temporary installations. The box is a steel skirt welded to the perimeter to keep dirt from getting in underneath. Dirt is pushed up on either side of the guard to create a ramp for crossing vehicles.

Boxed Cattle Guard

This design is popular at remote areas like cell phone towers and oil wells. They’re also used at construction site entrances as rumble strips, washouts for cleaning equipment and keeping the entrance clear of mud.

Although they lay directly on the ground, site preparation and proper drainage is a must. A bed of crushed gravel can go a long way to removing excess water and keep if from eroding your cattle crossing.

Site Specific

Foundations are critical to keep your livestock barrier in place and working effectively. They secure the guard from moving and transfer the passing load to the ground. The above recommendations should be considered and a local contractor consulted for a long-lasting installation.
