The white grey aluminium sheet for sign making have color code of Ral9002 Gray white, or 9003 Signal white. White grey aluminium sheet are a common used product for making signs for traffic, road, advertising, name plate, channel letter and so on. Among metal signs, aluminum signs account for the largest proportion. The main reason is that the nameplates of electromechanical products use a lot of aluminum plates. Regular painted aluminium sheet for sings making have standards to follow in addition to corrosion and painting, and surface treatment is also essential.
Generally, 1060 aluminum sheet can be used for signs, or 3003 aluminum sheet anti-rust series, but if the surface is painted, there is no need to use anti-rust. The white grey aluminium sheet for sign making is made of 3003 aluminum and 3004 aluminum sheet, and the oxidation effect of 5052 is the best for aluminum oxide plate. Beautiful. What are the advantages of using 3003 painted aluminum sheet to making signs?
1, Corrosion resistance and oxidation resistance. 3003 aluminum sheet has good formability and corrosion resistance, anti-oxidation, anti-ultraviolet radiation, excellent weather resistance, acid and alkali resistance, atmospheric fog resistance, high temperature resistance and water resistance.
2, The surface of the board is smooth and not easy to fall off. Using standardized production process, the surface of 3003 aluminum sheet is smooth, not easy to fall off, no peeling, no cracking.
3, Long service life. The strength of 3003 aluminum sheet is higher than that of 1000 series pure aluminum grades, weather resistance, stain resistance, easy bending and welding processing, etc., and it is economical and environmentally friendly.
In the products of metal signs, the proportion of aluminum signs accounts for more than 90% of the metal signs. For more than half a century, the use of white grey aluminium sheet for sign making has been enduring for a long time. The main reason is that aluminum has the most decorative performance. Many surface decoration techniques can be applied and exerted on aluminum materials, which is convenient for obtaining colorful and multi-combined advanced decorative layers. On the other hand, it is determined by a series of excellent properties of aluminum.
