About the introduction of coated steel plate

More and more figures of coated steel plates appear in our lives, and some may not have a special understanding of it. Today, I will give you a general introduction, hoping to help you.
The structure of coated steel plate mainly includes the following aspects.
1. Metal substrate: galvanized or cold rolled, aluminum plate, stainless steel plate, etc.
2. Polymer adhesive layer: The polymer fissions at a temperature of 15°C, bonding the upper and lower layers.
3. PE protective film: prevent scratches and external pollution during transportation and construction.
4. PVC/PET film: decorative panel.
5. Chemical treatment layer: improve the corrosion resistance of the substrate and the adhesion of the mucous membrane.
Laminated steel plate is mainly used in building curtain wall: curtain wall is the outer wall enclosure of the building, not load-bearing, and is a light-weight wall with decorative effect commonly used in modern large and high-rise buildings. The coated steel plate has strong weather resistance. 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 acid-base resistance 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.
