ASTM A755 0.85mm Brick grain Pre-finished PPGL Prepainted Galvalume color-coated Steel HDP Beckers for cladding
PPGI & PPGL (pre-painted galvanised steel sheet & pre-painted galvalume steel sheet), also known as pre-coated steel sheet or colour-coated steel sheet, consists of hot-dip galvanised steel sheet, hot-dip galvanised galvalume steel sheet and electro galvanised steel sheet.
After pre-treatment of the surface, one or more layers of organic coating are applied and baked solidified. Colour-coated steel sheets are lightweight, good in appearance, corrosion resistant and can be directly processed.
Colours are generally divided into grey, sea blue, brick red, etc. They are mainly used in advertising, construction, decoration, household appliances, electronics, furniture industry and transport.
The coatings used for coloured coils depend on the environment in which the resin is selected, such as silicone-modified polyester, polyvinyl chloride plastisol or polyvinylidene chloride.
