JIS G3321 0.45mm Brick grain Pre-finished PPGL Prepainted Galvalume
color-coated Steel HDP Beckers for cladding
PPGI & PPGL (prepainted galvanized steel & prepainted galvalume
steel) also known as pre-coated steel or color coated steel coil,
It is a product made of hot-dip galvanized steel sheet, hot-dip
galvalume steel sheet, electro galvanized steel sheet, etc.
After surface pretreatment, one or several layers of organic
coating are applied on the surface, and then baked and solidified.
The color coated steel coil is light in weight, beautiful in
appearance, and has good anti-corrosion performance, and can be
directly processed.
The color is generally divided into gray, sea blue, brick red, etc.
It is mainly used in advertising, construction, decoration, home
appliances, electrical appliances, Furniture industry and
transportation industry.
The coatings used for color coated steel coils are based on the
environment in which the resin is selected, such as polyester
silicon modified polyester, polyvinyl chloride plastisol,
polyvinylidene chloride, and the like.
Life span:
For the shortcomings of PE and SMP, HYDRO (now acquired by BASF)
and BECKER of Sweden developed a 60-80% weatherable HDP polyester
coating that can achieve PVDF coating in early 2000, and is
superior to ordinary silicon modification.
This coating has an outdoor weather resistance of 15-18years.The coating has excellent weather resistance, corrosion resistance
and solvent resistance, UV resistance, processability, and a tough
and durable aesthetic color.HDP coating is suitable for area with
high temperature and less industrial pollution.
