High-Strength A36 Tread Plate – In Stock, Cut-to-Size, Fast Global Delivery

ASTM A36 Checkered Steel Plate Product Description

Also known as diamond plate or tread plate, ASTM A36 checkered steel plate is a structural-grade carbon steel plate with a raised anti-slip pattern designed for safe flooring, walkways, trailers, stairs, and heavy-duty industrial surfaces. The embossed surface increases friction under wet, oily, or high-traffic conditions, improving worker safety and extending service life.

At CJM Steel, we supply A36 checkered plates in diamond, 5-bar, tear-drop, and other popular patterns with cut-to-size capabilities and export-standard packaging.
