The difference between aluminized color steel roll and ordinary color steel roll
Substrate selection: AZ150 (aluminum zinc content 150g/m2); G345A high strength galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon) corrosion resistance data: 5%NaCL 35 DEG C, 1000Hrs, Field good, Scribe, No, Blister, 2mm belowQ.U.V: 2000hrs, MAX.2 color, light to keep the rate above 90%, the above data show that aluminum zinc coated board (AZ150, G345A, PVDF) is very suitable for the extreme environment of buildings or other facilities, highly corrosion resistance and weather resistance, and the major steel plate can ensure the service life of 20 years. In addition, high strength steel has been widely used abroad, and it has good economic performance, and it is also the domestic development trend.
Ordinary color steel roll is a composite material, also known as color coated steel plate, is used in the continuous production line on the production line after surface degreasing, phosphating and other chemical coating treatment, painted with organic coatings, made by baking products. Both steel and organic materials are a little bit different. Both the mechanical strength of steel plate and easy molding performance, but also organic materials, good decoration, corrosion resistance.
Aluminized color coated sheet is a new type of material produced in China in recent years due to its high end applications. It is often used as an indication of CCLI. It is made of galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon), which is more galvanized and more corrosion resistant. It is processed by surface degreasing, phosphating and complexing treatment, and is coated with organic coating.
