Aluminium Checker Plate (Chequer Plate) Overview
Aluminium Checker Plate is a lightweight, anti-slip, and corrosion-resistant sheet metal with a raised surface pattern — usually diamonds or lines — used for flooring, stairs, ramps, toolboxes, and industrial surfaces.
Standard Sizes (in mm)
| Thickness (mm) | Width (mm) | Length (mm) |
| 1.5 – 6 | 1000 | 2000 |
| 2 – 8 | 1220 | 2440 |
| 2 – 8 | 1250 | 2500 |

Custom sizes are often available upon request.
Common Aluminium Grades
| Grade | Description | Uses |
| 1050 | Commercially pure, soft, good corrosion resistance | Decorative, light-duty panels |
| 3003 | Medium strength, excellent corrosion resistance, easy to work with | Toolboxes, cladding |
| 5052 | Stronger, marine-grade, excellent corrosion resistance, weldable | Marine ramps, steps, wet environments |
| 5754 | High strength, great for structural use, good corrosion resistance | Trailers, ramps, flooring |
| 6061 | High strength, heat-treatable, excellent machinability | Structural and industrial applications |
| 6082 | Structural alloy, good anodizing response, high strength | Platforms, bridges, heavy-duty floors |
