For private driveway use, we recommend the basic cattle guard as the most economical option.
Basic cattle guards
are a heavy duty structural .188 (3/16") walled pipe with a diameter of 3.5" or 4.5" depending on availability or request. Note that the walls of the basic guards are thicker then schedule 40.
Boxed cattle guards
are designed to sit on flat ground. Gravel underlayment is recommended for drainage of these cattle guards. In many cases these boxed cattle guards are used for wheel washes in construction sites. The basic cattle guard is designed to withstand the loads of full tractor trailers. This box is welded to the grate as one integral unit.
For a removable box, please select a flat cattle guard and then choose the removable box option when ordering.
