Introduction of coated steel plate

The structure of coated steel plate mainly includes the following aspects.
1. Metal substrate: thin metal plate (0.3mm-1.5mm) such as galvanized or aluminum plate.
2. Polymer color film layer: a decorative film with various textures.
3. PE protective film: prevent scratches and external pollution during transportation and construction.
4. Chemical treatment layer: improve the corrosion resistance of the substrate and the adhesion of the mucous membrane.
Laminated steel plates are mainly used in building curtain walls: curtain walls are building enclosures, and are commonly used lightweight walls with decorative effects in modern large and high-rise buildings.
The steel plate has strong weather resistance, and it has been tested by experiments that the surface color of the UVA-340 irradiation > 1000h has no obvious change, and the color can be kept unchanged outdoors and has strong self-cleaning ability.
It is also used on roofs and walls: the current factory buildings in acid-alkali environment require long-term chemical resistance and resistance to acid and alkali to meet the needs of coastal buildings for salt spray resistance. It can not only resist chemicals, It also has the characteristics of enhancing the durability of the roof and wall, self-cleaning, anti-cracking, and fire prevention. In terms of interior decoration: the fire and flame retardant properties of the board meet the mandatory requirements for indoor fire protection, solvent resistance, stable performance, and environmental protection.
