PPGL

PPGL
Product introduction and parameters
PPGL stands for pre-painted galvalume steel, which is a kind of color-coated steel with GL as substrate. It combines the strength of steel with excellent anti-corrosion of Zn-Al coating. The galvalume coating is made of 55% aluminum, 43.4% zinc, and 1.6% silicon. Except for their excellent corrosion resistance, PPGL sheets also have high thermal reflectivity, which makes them heat-resisting. Let’s review more details.

Material introduction

Color coated steel is a kind of building material widely used in the construction industry, which is made of cold-rolled steel plate as the substrate, through the steps of surface treatment, coating and curing. Color coated steel has the characteristics of diverse colors, beautiful appearance, high durability, light weight and high strength, and is widely used in construction, home appliances, decoration, automobiles and other fields.


The surface treatment of color-coated steel includes steps such as rust removal, phosphating and pickling to ensure the cleanliness and adhesion of the steel plate surface. In the coating process, high performance polyester, silicone modified polyester, polyurethane and fluorocarbon coatings are used, which have excellent weather resistance, chemical resistance and wear resistance. Finally, through high temperature baking and curing, the coating and the surface of the steel plate are closely combined to form a color coated steel with excellent properties.


The strength of color coated steel depends on the substrate material and thickness, and the durability depends on the coating, surface coating and processing technology, the coating has polyester coating (PE), fluorocarbon coating (PVDF), silicon modified coating (SMP), high weather resistant coating (HDP), acrylic acid coating, polyurethane coating (PU), plastic sol coating (PVC) and so on. The coating structure has two coating and one drying, two coating and two drying, etc., and the maintenance-free service life can be 10-30 years according to the different environment and atmosphere.
