Prepainted Steel Coil/Sheet Introduction:

Dimensions:
The width range of supplied prepainted steel sheet for ANSON steel is 700-1550mm; The thickness range of the design is 0.2-2.0 mm, which can provide the steel volume of 508 or 610mm inner diameter.
Steel Grade:
ANSON steel supplies steel grades of color coating products have high strength steel color, deep steel color coating, general molding used for color painting, and other advanced high-strength steel paints, such as double - phase steel or polyphase steel, which can improve the anti-wind ability.
Substrate Plate Type:
The base plate of ANSON steel color coated steel plate includes hot galvanizing, electro-galvanizing, aluminized zinc and other basic plates, as well as newly developed zinc-alumina magnesium base plate. The coating weight not only has the double thickness coating, but also has two different thickness coating.
Coated Layer Structure:
The coated products of ANSON steel are 2/2, 2/1, 1/1, 3/2, 2/1M, etc.
Coating Types:
ANSON steel color coating products include polyester (PE), fluorocarbon (PVDF) color coating, silicon modified polyester (SMP) color coating, high tolerance (HDP) and other paint varieties.
Surface Treatment:
Ordinary plane, embossing, printing and special surface effect painted steel plate (anti-scrape, suede, mesh, etc.)

Special Coating function For Prepainted Steel Coil/Sheet:

The width range of the supplied steel plate for ANSON steel is 700-1550mm; The thickness range of the design is 0.2-2.0 mm, which can provide the steel volume of 508 or 610mm inner diameter.
The antibacterial coating of ANSON steel can inhibit the breeding of escherichia coli, staphylococcus aureus, and green bacillus in hospitals, food factories and so on.
ANSON steel self-cleaning series coated steel plate by increasing the crosslinking density and forming hydrophilic coating to achieve self-cleaning effect.
The thermal insulation series of ANSON steel is reflected by the special pigments in the coating to reflect the infrared heat in the sunlight, so as to reduce the temperature of the building and save energy.
