The three names, "tread plate," "diamond plate," and "floor plate," can be confusing, but essentially they are all metal sheet or plate products, though they may have originated in different industries and applications. Each term refers to metal sheet or plate with a raised pattern on one side, and typically used as a slip-resistant surface or decorative siding.
The pattern on a tread plate may be alternating diamond or lozenge shapes or small individual blocks of raised bars in a checkerboard arrangement.
Rolled aluminum diamond plate comes in alloys including 3003 and 6061 (conforming to ASTM B632). Steel tread plate (steel tread plate is also called floor pate, aluminum is not) conforming to ASTM A786 comes in carbon, low-alloy, high-strength low-alloy, and alloy steel hot-rolled diamond plate.
Tread plate is available in a variety of thicknesses and load capacities, and it can be welded and cold worked.
The benefits of this versatile material are numerous, including:
Slip resistant – Raised pattern provides traction on steps, ramps, ladders, floors, tailgates, running boards, catwalks, loading docks, etc., even when wet, icy, or covered with snow, chemicals, or mud. Embossed firetruck quality (FTQ) tread plate meets NFPA industry safety regulations for slip resistance.
Corrosion resistant – Tread plate made of corrosion resistant metals, including stainless steel and aluminum alloys, provides years of service even under the toughest conditions, including marine locations.
Hygenic – Tread plate is easy to wash down and is able to resist damage from strong, corrosive cleaning agents. This makes it ideal for areas where frequent sanitizing is required, like food processing plants, kitchens, restaurants, ambulances, livestock transport, and more.
Protective – Tread plate prevents damage to walls, doors, corners, dollies, skids, etc. It also protects bumpers, treads, truck beds, tailgates, and bodies of commercial, off road, and other vehicles.
Attractive – Various raised patterns, materials and finishes are available for use in architecture, furniture making, etc. Firetrucks and shop walls are two places tread plate is commonly seen.
The benefits of steel or aluminum tread plate make it ideal for a multitude of applications. Tread plate can be found in parking lots, garages, stairways, step ladders, elevators, loading docks, warehouses, distribution centers, hospitals, factories, ships, floating docks, refrigerator trucks, walk-in freezers, elevators, walkways, handicapped access ramps, truck tool boxes, trailers, and much more.
