Not all cattle guards are built or installed the same way. The best design for a particular crossing depends on vehicle traffic, load requirements, roadway width, site conditions, installation method, and whether the cattle guard needs to be permanent or removable.

Traditional cattle guards installed over foundations are probably the most familiar design, but they aren't the only option. Boxed cattle guards can reduce the need for traditional poured concrete foundations, removable designs provide additional flexibility, and concrete cattle guards can be produced using reusable forms.

Understanding these differences makes it easier to choose a cattle guard based on the actual crossing rather than simply comparing products by appearance.

Traditional Cattle Guards Over a Pit

The traditional cattle guard design places a structural grid over an open area or pit. Vehicles travel across the rails while the open space and rail configuration create a barrier that cattle generally avoid crossing.

This type of installation typically requires site excavation and a properly prepared support system. Depending on the design, the cattle guard may be supported by poured concrete or precast foundations.

Traditional installations are commonly considered when the crossing will be permanent and regular vehicle access is expected.

Drainage is an important part of the installation. Water, soil, and debris should not be allowed to accumulate beneath the guard to the point that they interfere with the intended open area or contribute to maintenance problems.

Boxed Cattle Guards

A boxed cattle guard combines the upper cattle guard with a supporting steel structure underneath. Instead of relying on traditional poured concrete foundations, the box provides support for the cattle guard when installed on a properly prepared site.

This can be useful on private-property crossings where reducing concrete work is desirable. It can also change the amount of excavation, forming, curing time, and equipment involved in the project.

A boxed cattle guard still requires proper site preparation. The base needs to provide adequate support, approaches need to be properly constructed, and drainage remains important.

For more information, see our guide to cattle guards without concrete foundations.

Removable Cattle Guards

Some cattle guard installations are designed so the guard and its supporting structure can be removed or relocated more easily than a conventional permanent installation.

A removable design can make sense when access requirements may change, a crossing isn't intended to remain permanent, or a property owner wants greater flexibility in the future.

Removable does not mean that site preparation can be ignored. The cattle guard still needs adequate support, stable approaches, proper drainage, and an installation appropriate for the expected vehicle loads.

Concrete Cattle Guards

Concrete provides another approach to cattle guard construction. Instead of purchasing a completed steel cattle guard, reinforced concrete sections can be produced using a reusable form.

Barn World's reusable concrete cattle guard form can be used to produce individual reinforced concrete cattle guard sections for an installation.

This approach changes the project requirements because concrete, reinforcement, pouring, curing, handling, and placement become part of the construction process.

Our guide to making a concrete cattle guard with a reusable form explains the process in greater detail.

Round-Rail and Flat-Rail Cattle Guards

Cattle guards can also differ in the shape of the upper rails. Round-rail and flat-rail designs may look similar from a distance, but rail shape, spacing, construction, and load capacity are all important parts of the overall design.

Rail spacing should not be considered independently of the cattle guard itself. The entire unit needs to be designed for the intended livestock, vehicles, and application.

For a closer look at this part of cattle guard construction, see our cattle guard bar spacing guide.

Load Rating Can Matter More Than Cattle Guard Type

Installation style is only one part of choosing a cattle guard. The guard must also be appropriate for the vehicles expected to cross it.

A cattle guard used primarily by passenger vehicles and pickups may have different requirements than one regularly crossed by loaded trucks or heavy farm equipment.

The appropriate rating should be determined by the vehicles and loads expected at the crossing rather than by cattle guard style alone.

Site Conditions Can Determine the Best Design

The installation site can narrow the choices considerably. Soil conditions, drainage, roadway construction, available excavation equipment, and accessibility all affect how practical a particular installation will be.

A traditional foundation installation may make sense for one property, while a boxed cattle guard may simplify another. A removable system may be useful where future relocation is important.

Before selecting the cattle guard, evaluate the entire crossing rather than just the opening in the fence.

Cattle Guard Size Matters Too

The cattle guard must provide an appropriate crossing for the roadway and vehicles using it. Roadway width and the distance vehicles travel across the guard are different measurements, and both can influence product selection.

Our cattle guard dimensions and standard sizes guide explains these measurements and the sizes commonly used for different crossings.

Consider the Animals Using the Property

Cattle guards are primarily intended as barriers for cattle. They should not automatically be treated as a suitable containment method for every animal on a property.

Horses are an especially important consideration. Cattle guards should not be relied upon to contain horses, and an appropriate gate or horse-suitable barrier should be provided where horse containment is required.

Our guide to cattle guards and different animals discusses horses, sheep, goats, deer, dogs, and other animals in more detail.

Installation Is Part of Choosing the Right Type

Even the right cattle guard can perform poorly if the installation isn't appropriate for the site. Support, drainage, roadway approaches, fencing, and placement all contribute to the finished crossing.

Before beginning the project, review our step-by-step cattle guard installation guide for an overview of the installation process.

Choosing the Right Cattle Guard for Your Crossing

Rather than trying to choose between labels such as pit, grid, or rolling cattle guards, start with the requirements of the crossing.

Determine the roadway dimensions, expected vehicles, required load rating, livestock on the property, site conditions, foundation requirements, and whether the installation needs to be permanent or removable.

Those answers will usually make the appropriate cattle guard design much clearer.
