The road signs aluminium sheet with high corrosion resistance and durability performance can be produced in Haomei Aluminum. Road traffic signs are installed on outdoor highways and must withstand wind, sun and rain. Therefore, the materials are required to have corrosion resistance. Aluminum alloy sheets have excellent corrosion resistance, strong durability, strong adaptability to the environment, and good weather resistance. Moreover, the aluminium sheet alloy is easy to cut, light weight, high corrosion resistance and formability, and it is widely used to hang in the air.
Generally there are three aluminum grade of 1050/1060/1100 for road signs aluminium sheet. At present, most of the traffic road signs are processed from 1050 and 1060 aluminum alloy on the market. Roads with higher technical levels should use aluminum alloy plates with the grade of 3003, and large sign boards or sign plates in windy coastal areas should use aluminum sheet alloy with the grades of 3004 or 3104. If you make oxidation signs, especially oxidation dyeing signs, you must pay attention to it, otherwise it will affect the porosity of the oxide film and the adsorption performance and hardness level of the film.
Among the vast majority of products with metal signs on the market, aluminum signs are the most used, accounting for up to 90% of metal signs. The physical and chemical properties of road signs aluminium sheet are in line with the requirements related to the application in the sign, and it is easy to process. Aluminum has excellent ductility, easy to cut, and easy to stamp and form, which can meet the needs of special processes for signs. And there is no magnetism, aluminum is non-magnetic, and aluminum signs will not cause external interference to equipment.
