We have just talked about several classifications of color coated roll substrates. After we know several classifications of color coated roll, let's learn more about their characteristics. Let's have a look with Xiaobian.
1、 Electro galvanized substrate:
The coating is thin and the corrosion resistance is not as good as that of hot-dip galvanized substrate;
2、 Hot dip galvanized substrate:
It is to immerse the steel sheet into the molten zinc bath to make a layer of zinc adhere to its
surface. This galvanized sheet has good coating adhesion and weldability;
3、 Hot dip aluminum zinc substrate:
The product is plated with 55% Al Zn and has excellent corrosion resistance. Its service life is more than four times that of ordinary
galvanized steel plate. It is a new generation of galvanized sheet.
(1) It has good durability, corrosion resistance and longer service life compared with galvanized steel plate;
(2) It has good heat resistance and is not easy to change color
at high temperature compared with galvanized steel plate;
(3) Good thermal reflection;
(4) It has similar processability and spraying performance with galvanized steel plate;
(5) Good welding performance.
(6) It has good performance
price ratio, durable performance and competitive price. Therefore, whether architectural designers, engineers or manufacturers have been widely used in industrial buildings, steel structures and civil facilities, such as garage doors, gutters and roofs.
