Diamond & Tread Pattern Plates for Industrial Flooring, Ramps, Decks, and Heavy Equipment Use

Product Description:

ASTM A36 checkered steel plates, also known as diamond plate or tread plate, are hot-rolled carbon steel plates with a raised pattern surface. Engineered under the American ASTM A36 standard, these plates offer excellent weldability, formability, and structural strength, making them ideal for flooring and safety applications in industrial, automotive, and marine environments.

What Is ASTM A36 Patterned Steel Plate?

A36 is one of the most widely used structural-grade carbon steels in the United States and worldwide. The checkered version incorporates a textured surface, most commonly in diamond or 5-bar tread patterns, which enhances friction and reduces the risk of slipping in wet or oily conditions.

Unlike Q235B or SS400, ASTM A36 checkered plates are certified to U.S. standards, making them especially suitable for North American, South American, and export clients who require mill-compliant materials.

Popular Surface Patterns Available

• Diamond Plate (1-bar): The most common anti-slip surface
• Five Bar Tread Plate: Also known as quintet pattern
• Tear Drop Plate: Similar in slip resistance, often used interchangeably
• Customized Embossed Patterns: Available upon request

These patterned steel plates are ideal for structural floor reinforcement, vehicle running boards, construction stairs, and walkways.
