Prepainted steel sheet is a cost-effective and long-lasting product.
Prepainted Steel Sheet is also called color steel plate, color plate. The Prepainted Steel Sheet uses cold-rolled steel sheet and galvanized steel sheet as the substrate, and is continuously coated after surface pretreatment.
The following describes the Substrate Type of Prepainted Steel Sheet
Cold-rolled substrates, color-coated thick steel plates, cold-rolled substrates, colorful plates manufactured with smooth, beautiful, elegant appearance, and the production and processing characteristics of cold-rolled steel plates, but the small scars on the surface coating expose the cold-rolled substrates to the gas, exposing part of the iron Red rust was produced immediately. Therefore, such products are only used as temporary temporary protection measures and raw materials in the room.
The hot-dip galvanized steel coated organic coated product is a hot-dip galvanized steel coated coating. In addition to the protection of zinc, the surface organic chemical architectural coating also has protective and rust-proof treatment effects, and its service life is longer than that of hot-dip galvanized architectural coating. The zinc content of the hot-dip galvanized sheet is generally 180 g / m2 (two sides), and the zinc content of the hot-dip galvanized sheet is 275 g / m2.
Hot-dip aluminum-zinc color-coated plate can be selected as alumina thick steel sheet because of sprayed steel plate (55% ai-zn and 5% ai-zn).
Electro-galvanized color coated plate, Electro-galvanized plateis used as the substrate. Organic galvanized products are galvanized coating. Due to the thin galvanized layer, the zinc content is usually 20 / 20g / m2, which is not suitable for outdoor walls and roofs. But because of its beautiful appearance and excellent processing performance, it can be used in household appliances, acoustics, steel furniture, interior decoration, etc.
