Our 3003 5052 Aluminum Checkered Plate, widely named Aluminum Tread Plate or Diamond aluminum sheet, is pressed with standard 5-bar diamond patterns to deliver reliable slip resistance for high-traffic scenarios. 3003 Al-Mn alloy balances cost, weather resistance and easy forming, ideal for truck floors, cold storage and indoor industrial platforms; 5052 Al-Mg grade offers stronger tensile strength and outstanding saltwater corrosion resistance, perfect for marine decks, coastal facilities and heavy-load stair treads.
Standard specifications cover thickness 1.0–8mm, width 1000–1850mm, customizable length from 1000–6000mm. Available tempers include H14, H24, H32 with precise pattern height 0.7–1.5mm. All sheets meet ASTM B209 standards, supporting cutting, bending and welding processing. Lightweight yet durable, this diamond aluminum sheet avoids rust, cuts transport weight and extends service life for construction, vehicle, ship and decorative anti-slip projects.
