Export-Ready, Customized Galvanized Checkered Coils for Flooring and Industrial Projects

Our hot-dip galvanized checkered steel coils combine durable zinc protection with embossed anti-slip patterns such as diamond, 5-bar, and tear drop. As a reliable checkered steel coils supplier, CJM provides export-ready customized checkered steel coils for trailers, flooring, walkways, platforms, and mechanical fabrication.

We supply both plates and coils, supporting customers who need flat sheets for flooring or continuous coils for further processing. As a professional checkered steel coils company, CJM delivers export-ready products with strict quality control and customizable specifications for various regional standards.

Galvanized Checkered Steel Coils Overview

Our galvanized checkered steel coils are produced by hot-dip galvanizing a carbon-steel substrate, followed by embossing raised patterns to increase slip resistance. The zinc coating protects against corrosion, while the patterned surface improves traction in industrial and construction environments.

This page focuses on checkered steel coils, with flat plates also available on request for cut-to-size orders.

Key Advantages of Checkered Steel Coils

• Corrosion Resistance – Hot-dip zinc layer protects against moisture and rust.
• Slip-Resistant Surface – Diamond, tear-drop, or 5-bar patterns provide strong grip.
• Flexible Processing – Coils support continuous stamping, slitting, and fabrication.
• Cost-Efficient for OEM Buyers – Ideal for trailer floor manufacturers, stair tread producers, and metal fabrication plants.
• Customizable Supply – Width, thickness, zinc coating, and coil weight can be fully customized.

Surface Patterns of Checkered Steel Coils

We provide various embossed patterns to meet different anti-slip and aesthetic requirements:

Pattern Name	Description	Common Uses
Diamond Plate	One-directional raised diamond shape	Truck beds, trailers, loading docks
Tear Drop / Lentil	Raised droplet shape with good grip	Factory floors, staircases
5-Bar Pattern	Five raised bars in parallel	Walkways, catwalks, vehicle ramps
Durbar Plate	Non-slip pattern common in UK	Industrial & marine flooring
