Floor Plate – Diamond Plate

Superior Steel Supply inventories, distributes and processes a wide range of carbon floor plate also called diamond plate or checker plate. Floor plate typically comes in a range of 14ga up to ½” thick and can be procured widths of 48”, 60”, 72” and in some cases 96” wide. Standard lengths are typically 96”, 120” and 240”.
Superior Steel Supply can process your floor plate requirements to size with our inhouse burning and shear services.
Floor plate is produced at the mill in coil form and is then leveled to create sheets on a leveling line. Floor plate coils produced domestically can accomplished by Electric Arc Furnaces (EAF) mills that use 95%+ post-consumer recycled scrap, by integrated mills that use iron ore, cooked coal (coke) and limestone or by a rerolling mill that is buying semi-finished slabs from other sources.
Floor plate is generally produced from the mill with the grade specification of ASTM A786, but can be sourced in ASTM A36 for 3/16” and thicker.
- ASTM is the American Society for Testing and Materials
