Today, the editor will take you to learn about the relevant knowledge of color-coated substrates!
1. Look at substrates according to industry divisions
Color-coated rolls are lightweight, beautiful and have good anti-corrosion properties. They are generally available in gray white, sea blue, brick red and other colors. They are mainly used in the advertising industry, construction industry, home appliance industry, transportation industry and other industries.
Color-coated panels for construction: generally based on hot-dip galvanized steel sheets and hot-dip galvanized steel sheets
It is mainly processed into corrugated boards or sandwich panels with polyurethane, and is used to build roofs, walls, doors and other industrial and commercial buildings such as steel structure factories, airports, warehouses, and freezers.
Color-coated boards for home appliances: generally electro-galvanized and cold plates are used as substrates
Used in the production of refrigerators and large air conditioning systems, freezers, bread machines, furniture, etc.
Color-coated sheets for transportation industry: generally based on electro-galvanized and cold plates
Mainly used in oil pans, automotive interior parts, etc.
2. Look at the characteristics based on the substrate
Electro-galvanized substrate: Usually the zinc layer is thin and its corrosion resistance is not as good as that of hot-dip galvanized substrate
Hot-dip galvanized base plate: In addition to the protective effect of zinc, the organic coating on the surface of hot-dip galvanized color-coated plate also plays a role in isolating protection and preventing rust. Its service life is better than that of electro-galvanized plate.
Hot-dip Al-Zn base plate: Hot-dip Al-Zn steel plate (55% Al-Zn) is used as the new coating base plate, which has excellent anti-corrosion performance. Its service life is four times that of ordinary galvanized steel plates. It is an upgrade of galvanized plates. product
The specific selection of substrates needs to be selected according to the customer's requirements and usage scenarios. If you have any questions, please feel free to call us at +86 158 2468 7445!
