Aluminum-galvanized coloured steel coil is a new material produced in recent years in view of high-end applications in China, which is commonly referred to as CCLI. It is an enterprise product which is made of galvanized aluminized steel sheet (55% aluminium, 43% zinc and 1.6% silicon) with better corrosion resistance than galvanized steel sheet, treated by degreasing, phosphating and complexing on the surface, coated with organic paint and baked.
Coloured steel coil
Substrate selection: AZ150 (150 g/m2 of galvanized aluminium); G345A high strength galvanized steel sheet (55% aluminium, 43% zinc and 1.6% silicon) corrosion resistance data: 5% NaCL 35 C, 1000Hrs, field is good, Scribe No Blister 2 mm below Q.U.V: 2000 hrs, color difference MAX.2, light retention rate more than 90%. The above data show that the galvanized steel sheet (AZ150, G34) 5A, PVDF) is very suitable for buildings or other facilities in extreme environments. It is very resistant to corrosion and climate, and the major steel mills of this kind of steel plate can guarantee the service life of more than 20 years. In addition, high strength steel plate has been widely used abroad, with better economic, but also the domestic future development trend.
Coloured steel coil
Ordinary color steel coil is a kind of composite material, also known as color coated steel plate. It is an enterprise product made by continuous chemical transfer treatment of strip steel on production line, such as degreasing and phosphating on the surface, coating with organic paint and baking. It's a little bit of both steel plate and organic material. It has not only the mechanical strength and easy-to-form property of steel plate, but also the good decorative and corrosion resistance of organic materials.
