What Is 3003-H22 Checker Plate
3003-H22 aluminum checker plate is a versatile anti-slip material commonly used for flooring in buses, trucks, and trailers, toolboxes and loading ramps, interior cladding in cold storage units, wall protection in commercial kitchens, and decorative surfaces in retail and public areas. The H22 temper indicates strain hardening followed by partial annealing, providing an ideal balance between formability and strength.
How H22 Compares with Other Tempers
The H22 condition is strain hardened to a controlled level and then partially annealed, which softens the material slightly for better forming while retaining useful strength. Compared with the harder H24 or the softer O temper, H22 offers a practical middle ground for general-purpose fabrication where the plate is sheared, bent, and welded.
Comparison with 5052 and 6061 Tread Plates
3003-H22 offers excellent corrosion resistance, moderate strength, superior formability, and cost-effectiveness. 5052 tread plate provides higher strength and better saltwater corrosion resistance, ideal for marine applications. 6061 checker plate offers superior strength, weldability, and durability for structural use and heavy-duty floors. Customers in light-to-medium duty applications typically choose 3003 for affordability and performance.
Surface Patterns
The most popular patterns for 3003-H22 checker plate are five-bar tread plate, diamond or 1-bar plate, and rice-grain and lentil patterns. These anti-slip textures enhance safety and aesthetics in public walkways, warehouse platforms, and stair treads, and are available in standard or custom designs.
Fabrication
One key advantage of 3003-H22 is its superior formability. Compared with harder grades such as 6061-T6, the patterned sheet can be easily sheared and cut, bent with minimal cracking, and welded using standard aluminum welding processes, making it ideal for fabricators needing material that adapts to curved surfaces, folded sections, and detailed shapes.
Dimensions and Finishes
Thickness is typically 1.5 to 6.35 mm with widths up to 1500 mm and standard or custom-cut lengths. Surface finish options include mill finish, bright polished, and color coated, with PVC film protection or paper interleaving available to preserve surface quality.
