Standard flat-rolled steel tolerances (ASTM A568) do not apply. This PDF defines unique measured excluding the raised pattern. It also details flatness tolerances (camber, waviness, and out-of-square) specifically for heavy-duty floor applications. ASTM A786 is the definitive specification for the
ASTM A786 is the definitive standard specification for hot-rolled carbon, low-alloy, high-strength low-alloy (HSLA), and alloy steel floor plates. Often referred to as "diamond plate" or "tread plate," these materials are essential for industrial safety due to their raised-pattern surface designed for traction. This PDF defines unique measured excluding the raised
If you are reviewing the , you will notice that it does not stand alone. Unlike A36 (which covers structural strength), A786 focuses on the geometry and surface pattern of the plate. Here are the critical clauses found within the document:
