The substrate of Prepainted galvanized steel coil is cold-rolled substrate, hot dip galvanized substrate and electro-galvanized substrate. Coating types can be divided into polyester, silicon modified polyester, vinylidene fluoride and plastic sol. The surface condition of prepainted galvanized steel coil can be divided into coated coil, embossed coil and printed coil. Prepainted galvanized steel coil is widely used in household appliances and transportation industries. For the construction industry, it is mainly used for steel structure workshop, airport, warehouse and freezing industries, commercial buildings such as roof walls and doors.
Composite panels commonly used insulation materials are rock wool, glass fiber cotton, polystyrene (EPS), polyurethane, etc., these are low thermal conductivity, resulting a good thermal insulation effect. High-strength steel coil manufactured with high-strength steel substrate (tensile strength 5600kg / cm) and coupled with the most advanced design and roll forming, therefore, prepainted galvanized steel coil has excellent structural characteristics.
Prepainted galvanized steel coil not only has high mechanical strength, easy-forming properties, but also has good decorative performance and corrosion resistance. Prepainted galvanized steel coils the emerging material respected in the world today. With the development of science and technology, prepainted galvanized steel coil has shown more and more vitality and broad market prospects. It has been widely applied in construction, home appliances, electromechanical, transportation, interior decoration, office equipment and other industries.
