What is the difference between ordinary color steel coil and galvanized color coated plate?
Color steel coil is a composite material, also known as color steel plate. The product is continuously chemically transferred to the strip on the production line, such as degreasing, phosphating, etc., and is coated with organic paint and dried.

Aluminum galvanized color coated board is a new material produced by domestic high-end applications in recent years, commonly known as CCLI. It is made of galvanized aluminum plated steel (55% aluminum, 43% zinc, 1.6% silicon). It has better corrosion resistance than galvanized steel. It is degreased, phosphatized, complexed and coated with organic paint. Made.

Substrate selection: AZ150 (150 g/m2 galvanized aluminum); G345A high-strength galvanized aluminum steel sheet (55% aluminum, 43% zinc and 1.6% silicon) Corrosion resistance data: 5% NaCl35 C, 1000 hours, good site The scribe is less than 2 mm.

Q.U.V: 2000 hours, the maximum color difference is 2, and the light retention rate is over 90%. The above data shows that the aluminized color-coated plates (AZ150, G345A, PVDF) are very suitable for buildings or other facilities in extreme environments, with excellent corrosion resistance and weather resistance, and can guarantee the longer service life of these steel plates. Worked in major steel plants for 20 years. In addition, high-strength steel sheets have been widely used abroad, have good economics, and are also a domestic development trend.

Ordinary color steel coil is a composite material, also known as color coated steel sheet, which is formed by continuous chemical transfer treatment of strip steel on the production line by surface degreasing, phosphating, organic coating and baking. It has both steel and organic materials. It not only has the mechanical strength and easy forming properties of the steel sheet, but also has good decorative and corrosion resistance.
