Checkered carbon steel coil with Diamond Pattern for Anti-Slip Floor

Checkered carbon steel coil, also known as a tread plate or floor plate coil, is a hot-rolled steel product with a raised pattern on one surface for enhanced safety. This functional steel combines the strength of carbon steel with an anti-slip textured surface, making it ideal for applications requiring both durability and slip resistance .
