Aluminum tread plate 1100 1060 3003 5052 H24 H26
Aluminum tread plate, also known as aluminum checker plate or diamond plate, is an essential material widely used across various industries due to its durability, lightweight properties, and distinctive textured surface that offers slip resistance. Among the most common aluminum alloys employed in tread plates are 1100, 1060, 3003, and 5052. When combined with tempering conditions like H24 and H26, these alloys provide a balance of strength, corrosion resistance, and formability suitable for numerous applications.
Aluminum Tread Plate Alloys and Tempering
Aluminum tread plates feature raised patterns that increase grip, making them ideal for floorings, ramps, vehicle bodies, and various industrial surfaces that require enhanced safety.
Common Aluminum Alloy Families Used:
| Alloy | Primary Characteristic | Typical Uses |
|---|---|---|
| 1100 | Commercially pure aluminum (99%+), excellent corrosion resistance, high ductility | Decorative and architectural applications, chemical equipment |
| 1060 | Very high purity, excellent corrosion resistance and electrical conductivity | Electrical and food processing industries |
| 3003 | Alloyed with manganese, moderate strength, good corrosion resistance | Roofing, siding, and edging materials |
| 5052 | Alloyed with magnesium, high strength, excellent corrosion resistance, particularly in marine environments | Marine, automotive, and industrial applications |
Tempering States: H24 and H26
The temper codes reflect different mechanical and chemical conditioning after production:
| Temper | Description | Properties |
|---|---|---|
| H24 | Strain-Hardened and partially annealed | Medium strength, excellent formability, good weldability |
| H26 | Strain-Hardened and quarter annealed | Higher hardness and strength with moderate ductility |
Tempering directly affects properties like tensile strength and flexibility essential for choosing the right tread plate for your application.
