Henan Henry can manufacture aluminium sheet for sign blank in various gauage and pattern. Aluminum sign blanks are available in all of the most popular shapes with many available with radius corners, pre-applied borders and pre-drilled holes for mounting hardware.  Alloy1100, 3003, 5052, 5454, 5754 are tailored as your requirements.

Characteristics of aluminum sheet: In addition to the above reasons of metal road traffic sign factory, the physical and chemical properties of aluminium coincide with the requirements related to the application of the sign. Here is a brief introduction.

1. Light weight; the density of aluminium is 2.702 g NaN3, which is 1/3 of that of copper and aluminium. The aluminium label will not increase the weight of equipment, but also save costs.

2. Easy to process; Aluminum sheet has excellent ductility, easy to cut, and easy to stamp, which can reflect the needs of the strange process of road traffic signs.

3. Good corrosion resistance; Hard and compact oxide films can be formed on the surface of aluminium and its alloys.

4. Weather resistance is good; Aluminum oxide film, many substances do not corrode it, and it will also have good durability in harsh environment in industrial areas and coastal areas.

5. No magnetism; aluminum sheet is non-magnetic, and the aluminium label will not interfere with the instrument and equipment.

6. Resources are abundant; aluminium reserves are considerable, and the annual output of aluminium products is second only to that of iron and steel, ranking second in the world's total metal production.
