Hot-dip galvanized substrate

The product obtained by coating the organic coating on the hot-dip galvanized steel plate is the hot-dip galvanized color coated plate.  In addition to the protective effect of zinc, the organic coating on the surface also plays a role in isolating protection and preventing rust, and the service life is longer than that of the hot galvanized sheet.  The zinc content of hot-dip galvanized substrate is generally 180g/m2 (double-sided), and the maximum galvanizing amount of hot-dip galvanized substrate for external construction is 275g/m2.

Hot aluminized zinc substrate

The hot-plated aluminum zinc steel plate (55%Al-Zn) is used as the new coating substrate, usually containing 150g/㎡ of aluminum zinc (double-sided).  The corrosion resistance of hot plated aluminum zinc plate is 2-5 times that of hot galvanized plate.  Continuous or intermittent use at temperatures up to 490 ° C will not result in severe oxidation or oxide skin.  The ability to reflect heat and light is 2 times that of hot galvanized steel, and the reflectivity is greater than 0.75, which is an ideal building material to save energy.

Color coated roll use

Color coated roll has light weight, beautiful appearance and good corrosion resistance, but also can be directly processed, the color is generally divided into gray, blue, brick red, mainly used in advertising, construction, home appliance industry, electrical appliance industry, furniture industry and transportation industry.  

The paint used in the color coating volume is selected according to the different use environment, such as polyester silicon modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride and so on.  Users can choose according to the use. 

In the top coating link, it is mainly the choice of color and the treatment of the appearance effect, using PVDF, PE, HDP and other resins as coating materials, so that the color coated steel coil has different colors and glossness on the surface.  The main part of the varnish is to increase the gloss of the coating and improve the anti-fouling performance.

Solidify After finishing the coating, the color-coated steel coil needs to be cured by baking.  During the baking and curing process, the color coated steel coil is sent into a high temperature oven, and different temperatures and times are set according to the different materials selected.  Through curing, the coating material can be fully reacted and cross-linked, thereby improving the performance indicators such as weather resistance, hardness and adhesion of the color coated steel coil.  

Cutting and packing After the above process, the color-coated steel coil needs to be cut and packaged after it is made.  Cutting is mainly to cut the color coated steel coil into the required size according to customer needs and product specifications.  Packaging is to cut the color coated steel coil for packaging, so as to avoid external pollution and damage.
