What is color coated steel coil?
Color coated steel coil refers to the steel coil coated with color organic coating or film on the surface of galvanized steel coil, aluminum coated steel coil, tin coated steel coil or cold-rolled steel coil. On the one hand, it plays the role of protecting metal, on the other hand, it plays the role of decoration. This kind of steel coil coating can be divided into organic coating, inorganic coating and composite coating.
Color coated steel coil has light weight, beautiful appearance and good anti-corrosion performance, and can be processed directly. It provides a new raw material for construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry, electrical industry and so on Color coated steel coil products include cold-rolled base coil, color coated steel coil, hot-dip galvanized color coated steel coil, hot-dip aluminum zinc color coated steel coil (galvanized aluminum color coated coil with aluminum content of about 5% and aluminum zinc color coated coil with aluminum content of about 55%), electro galvanized color coated steel coil, etc
HDT steel is a professional manufacturer of color coated galvanized steel coil. There are four main types of color coated galvanized steel coil.
1、 Ester coated (PE) color coated steel coil
PE polyester color coating roll has good adhesion, rich colors, wide range in formability and outdoor durability, medium chemical resistance and low cost. PE polyester color coating roll has the advantages of high cost performance. It is recommended to use PE polyester color coating roll in a relatively friendly environment;
2、 High weather resistance coating (HDP) color coated steel coil;
HDP high weather resistant color coating roll has excellent color retention and UV resistance, excellent outdoor durability and pulverization resistance, good adhesion of paint film coating, rich colors and excellent cost performance. The most suitable environment for high weather resistance HDP pressure type color coating roll is bad weather environment. For example, in areas with strong ultraviolet rays such as plateau, we will recommend the use of HDP high weather resistance pressure type color coating roll;
3、 Silicon modified coating (SMP) color coated steel coil;
SMP silicon polyester color coating roll has good hardness, wear resistance and heat resistance; And good external durability, pulverization resistance, gloss retention, general flexibility and medium cost. SMP silicon modified polyester profiled color coating roll is most suitable for high temperature plants, such as steel mills and other indoor environments with high temperature. Generally, SMP silicon modified polyester profiled color coating roll is recommended;
4、 Fluorocarbon coating (PVDF) color coated steel coil;
PVDF fluorocarbon color coating roll has excellent color retention and UV resistance, excellent outdoor durability and pulverization resistance, excellent solvent resistance, good formability, dirt resistance, limited color and high cost. PVDF profiled color coating roll has the characteristics of high corrosion resistance. Many factories with strong corrosive environment will choose PVDF profiled color coating roll. In addition, there are often humid sea winds at the seaside, which are highly corrosive. Generally, PVDF profiled color coating roll will also be selected
