Checkered Steel Plate: Types, Sizes, Weight, Applications & Price Guide

Checkered steel plates, also known as checker plate, diamond plate, or steel tread plate, are widely used in construction, industrial flooring, and transportation projects for their excellent anti-slip performance and durability.
For distributors, contractors, and buyers, understanding the types, patterns, available sizes, weight, and price of checkered steel plates helps ensure the right material selection for your application.

What Is a Checkered Steel Plate?

A checkered steel plate is a flat steel sheet with a regular raised pattern —such as diamond, lentil, or five-bar — embossed onto one side. This textured surface enhances traction and makes it ideal for walkways, ramps, stair treads, loading platforms, and truck beds. Most checkered plates are produced by hot rolling, which gives them excellent mechanical strength and wear resistance.

Types, Patterns & Grades of Checkered Steel Plates

Checkered plates can be classified by material composition and surface pattern. Each combination affects strength, corrosion resistance, and appearance.

By Material Type

1. Mild Steel Checkered Plate

Mild steel checkered plates (MS checker plates) are the most common and economical option. They are easy to fabricate, weld, and cut—making them suitable for general structural and flooring use.

• Typical Grades: Q235, A36, SS400, S235JR
• Surface Finish: Hot rolled, uncoated
• Applications: Factory floors, staircases, and truck platforms

2. Carbon Steel Checkered Plate

Carbon steel checkered plates offer slightly higher strength and hardness compared to mild steel. They are used where wear resistance and strength are more critical.

• Common Grades: ASTM A283, A572 Gr.50, Q345, S275JR
• Use Cases: Heavy machinery flooring, industrial ramps, transport trailers

3. Galvanized Checker Plate

Galvanized checker plate is coated with a layer of zinc to resist corrosion, ideal for outdoor or humid conditions. They retain the same anti-slip texture while providing enhanced durability and longer lifespan.

• Surface Treatment: Hot-dip galvanized or electro-galvanized
• Common Applications: Outdoor ramps, marine platforms, wet areas, stair treads

By Pattern Style

The surface pattern directly affects slip resistance and aesthetics. Popular checkered plate patterns include:

• Diamond Plate Steel (Tread Plate) – The most popular design for industrial floors and loading areas.
• Five-Bar Checker Plate – A linear anti-slip pattern ideal for stairs, walkways, and warehouse flooring.
• Lentil / Teardrop Pattern – Offers a smoother, uniform surface suitable for decorative or light-duty indoor use.
• Hexagonal / Honeycomb Plate – Heavy-duty grip pattern used for equipment platforms and machinery floors.

Both diamond and five-bar tread plates are available in mild steel, carbon steel, and galvanized finishes, allowing selection based on strength, corrosion protection, and cost.

Standard Sizes, Thickness & Theoretical Weight

Checkered steel plates are typically supplied in standard sizes for convenience in fabrication and transportation. Below are common size and weight references for typical patterns and grades.

Nominal Thickness (mm)	Standard Size (mm)	Weight (kg/m²)
2.5	1000 x 2000	19.63
3.0	1250 x 2500	23.55
5.0	1500 x 6000	39.25
6.0	1220 x 2440	47.10
8.0	1500 x 6000	62.80

Note: The above values represent theoretical weights for reference only. Actual weight may vary slightly due to manufacturing tolerances and surface patterns.

Customized dimensions such as 8×4 checker plate, 5mm chequered plate, or galvanized tread sheet can be supplied according to project needs.
