FAQ
Most enquiries reduce to a small set of recurring technical questions.
01 What is checkered / diamond plate?
Checkered (or diamond) plate is a hot-rolled carbon steel plate with a raised diamond or teardrop pattern on one side for slip resistance and decorative use.
02 What are typical applications?
Checkered plate is widely used for industrial flooring, walkways, stair treads, ramps, vehicle beds, equipment platforms and decorative cladding.
03 What thickness range is available?
Standard thickness 2 - 12 mm. Heavier thicknesses up to 25 mm are available on request.
04 What patterns are available?
Standard raised diamond (one-bar / five-bar) pattern is most common. Teardrop and lentil patterns are also available.
05 Can checkered plate be supplied with mill certificate?
Yes. EN 10204 3.1 mill test certificate with chemical composition and mechanical properties is standard.
