HAOMEI Aluminum Co., Ltd. is a professional aluminum processing, manufacturing, and sales company specializing in hot-rolled and cold-rolled aluminum sheets and plates. We supply large-format aluminum diamond plates in a wide range of thicknesses and dimensions. The 4x8 ft aluminum diamond plate sheet is one of the most commonly requested sizes. Different thicknesses and colors are available, including 1/4-inch aluminum diamond plate and white, black, and red diamond tread plates.
Aluminum diamond plate, also known as aluminum diamond tread plate, aluminum checker plate, embossed aluminum plate, or anti-slip aluminum plate, is a type of metal sheet with regular raised diamond patterns formed on the aluminum surface through rolling or embossing processes.
Its surface pattern is clear, three-dimensional, and evenly arranged. In addition to delivering reliable anti-slip performance, it also offers light weight, an attractive appearance, corrosion resistance, and easy fabrication. Aluminum diamond plate is widely used in vehicle manufacturing, architectural decoration, machinery and equipment, ship decks, stair treads, platform walkways, cold-storage floors, and industrial protection applications.

1. Excellent Anti-Slip Performance
The raised diamond pattern is distributed in a cross-grid layout, effectively increasing friction at the contact surface. The embossed pattern provides all-direction traction, with a slip-resistance coefficient of 0.65 or above.
2. Lightweight and High Strength
Aluminum has a density of approximately one-third that of steel. It reduces structural load while making transportation and installation easier, significantly lowering construction time and costs.
3. Outstanding Corrosion Resistance
Aluminum alloys naturally form a dense oxide film on their surface, providing inherent rust resistance. This protective layer helps prevent oxidation and corrosion while providing good resistance to acids and alkalis.
4. Good Fabrication Performance
Aluminum diamond plate is easy to cut, weld, bend, and process into complex sizes and shapes. It is suitable for most fabrication processes and provides good formability, drillability, and weldability. It also offers excellent electrical and thermal conductivity.
5. Easy Maintenance
The surface is smooth, easy to clean, stain-resistant, and simple to wipe down. Its corrosion resistance reduces the need for frequent maintenance and rust-removal treatment.
6. Attractive and Durable
The highly polished surface and clear pattern provide a clean, modern appearance. Various surface treatments and color customization options are available to suit industrial, minimalist, and other design styles.
7. Environmentally Friendly and Recyclable
Aluminum alloy is a highly recyclable metal material. It supports modern green manufacturing, energy conservation, emission reduction, and circular-economy development.
Construction: Stair treads, anti-slip corridor platforms, elevator car flooring, moisture-proof basement walkways, architectural curtain walls, roofing, and wall cladding.
Transportation: Truck and bus flooring, trailer flooring, ship decks, anti-slip subway interior surfaces, airport conveyor belts, and loading ramps.
Industrial Manufacturing: Workshop operating platforms, equipment maintenance walkways, warehouse shelving panels, assembly line workbenches, and cold storage flooring.
Decoration: Commercial wall surfaces, storefront facades, furniture panels (coffee tables, cabinets), outdoor landscaping, hotel lobby walls, and shopping mall ceilings.
Other Applications: Toolboxes, wall panels, dock surfaces, trench covers, and walkways. In the home appliance sector, it is also commonly used for chest freezers, cold storage units, refrigerators, solar water heater reflectors, lighting fixtures, luggage, disinfection cabinets, air conditioning ducts, and machinery housings.
Aluminum diamond plate supports a variety of surface-treatment processes to meet different environmental, performance, and aesthetic requirements.
Anodizing
Anodizing forms a protective aluminum oxide layer on the surface through an electrochemical process. The resulting surface has a certain level of hardness and corrosion resistance, with a matte metallic appearance. Coloring agents can be added during the process to produce a wide range of colors.
Coating
Available coating processes include PVDF coating, baked paint coating, and powder coating. PVDF coating offers strong weather resistance and can be used outdoors for 15–20 years without fading or peeling.
Mirror Finish
The surface is extremely smooth, with reflectivity close to 90%. It provides high cleanliness and is an ideal choice for decorative applications.
Mill Finish
A standard rolled surface with a certain degree of roughness.
Other Treatments
Wood-grain transfer printing, electroplating, oxidation coloring, and other processes are available to meet more diverse decorative requirements.
For customization, manufacturers can provide tailored solutions for required sizes, colors, and thicknesses. Custom pattern tooling, slitting, cutting, punching, and other processing services are also available.
Q1: Will slip resistance decrease in oily environments?
A: The diamond pattern helps break up oil films, and the slip-resistance coefficient can still remain above 0.5. For heavily oily environments, deeper patterns or sand-textured surface treatment are recommended.
Q2: Can you provide customized processing services?
A: Yes. We can provide custom cutting, CNC machining, bending, drilling, protective film application, anodizing, coating, and other secondary processing services according to customer requirements.
Q3: Can it be used outdoors for a long time? Will it rust?
A: Aluminum itself is naturally rust-resistant. After anodizing or PVDF coating, it can be used outdoors for 15–20 years. For strongly acidic or alkaline environments, 5000-series or 6000-series alloys are recommended.
Q4: What installation methods are available?
A: Welding, bolt fastening, structural adhesive bonding, and clip-hanging installation are all available. The appropriate method should be selected according to the substrate and load-bearing requirements.
Q5: What is the approximate price?
A: Prices vary depending on alloy grade, thickness, surface treatment, and fluctuations in aluminum prices. As a reference, 1060 aluminum diamond plate is approximately RMB 15–25/m², 3003 is approximately RMB 25–40/m², 5052 is approximately RMB 40–60/m², and 6061 is approximately RMB 50–80/m² for sheet material only. Coating may add an additional RMB 20–50/m². Please contact the supplier for real-time pricing.
