Anodized Aluminum Sheet For Traffic Sign
Anodized aluminum sheet for traffic sign is a commonly used material for making traffic and road signs because of its corrosion resistance, abrasion resistance, light weight and excellent visual effect. Usually, 1000 series or 3000 series aluminum alloy is used. 1000 series aluminum has higher purity and better corrosion resistance; 3000 series aluminum is added with manganese and other elements to improve strength, while maintaining good formability and corrosion resistance. H14 or H24 is more common tempers of anodized aluminum sheet for for traffic sign, H means hard state, and the larger the number means higher hardness. H14 is slightly hardened and suitable for applications requiring a certain degree of softness; H24 is fully hardened and suitable for applications requiring higher strength and hardness. Anodized aluminum sheet for for traffic sign are generally available in thicknesses from 1.0mm to 3.0mm, depending on the size of the sign a...
