Driveway Grates to Keep Out Deer Deer grates, mostly derived from the cattle guards long used on ranches, allow your driveway to stay open while keeping out the deer. They do this by placing a massive grate in the ground that deer will not or cannot cross. These grates come in several varieties. The most highly regarded (see Metal deer grates with round pipes) places heavy 3-inch steel pipes spread several inches apart across the driveway. Another type, which we do not recommend, uses square pipes instead of round ones. Still another, made of reinforced concrete, places a series of cement “waves” across the drive way (see Concrete deer grates).
Metal deer grates with round pipes (items 19-16 thru 19-20) provide reliable driveway protection against deer. They consist of massive 3-inch steel bars, separated by 3-inch spaces, that are suspended over a 12-inch deep cavity that deer will not step into. These massive bars consist of 3" OD schedule 4.0 pipe weighing 6.5 pounds per foot. The bars are supported by frames (there are 2 frames per grate) made with 12-inch steel “C” channels on the long (81-inch) sides that in turn are connected by three 8-inch “I” beams (one on each end and one in the middle). The two middle pipes in each 81-inch array are mounted on a small frame that can be unbolted from the main frame and removed temporarily when one wishes to clean out the main cavity.
These grates aren’t cheap, but they are highly effective. Designed to support a load of up to 20 tons, they come in four widths (10, 12, 14, or 16 feet). Each grate has a high-quality powder-coat finish and is available in black, grey, or green. For more information about installation of these grates and how to select them, see Deer Fence Installation: Driveway Gates and Driveway Grates. Customers purchasing this product should allow four weeks for delivery. The prices listed below may be approximate and are subject to periodic minor changes with the price of steel. Shipping quotes are available upon request. Concrete deer grates. There is some controversy in the deer fence trade about how well these concrete deer grates work, but they certainly are less expensive than their metal cousins. The grates are precast in two pieces, both of which make extensive use of half-inch steel reinforcing bars. Their wave-like concrete fingers are 3 inches wide with 5-inch spacing. Like the round pipe grates, they will hold up under the heaviest loads and frequent traffic. These grates, which have been approved for use on state roads in many states, are available for immediate delivery. Call us at 508-888-8305 for shipping quotes and delivery coordination.
