Chequered Plates — IS 3502 & ASTM A786

What is a Chequered Plate?

Chequered plate, also called floor plate or diamond plate, is hot-rolled steel plate with a raised pattern on one surface. The pattern gives grip underfoot and helps drainage, while the plain side can be welded or bolted to supporting steel. In India, steel chequered plate is covered by IS 3502; ASTM A786 covers rolled floor plate. Thickness is usually stated on the base plate excluding the pattern. It is used on industrial platforms, stair treads, walkways, trench and drain covers, vehicle floors and loading ramps.
