1.color coated board /PPGI plate
2.Introduction
Color plate to cold rolled steel and galvanized steel as the substrate, after the surface pretreatment (degreasing, cleaning, chemical conversion treatment), in a continuous process of coating, after baking and cooling and made.
Painted plate, also known as color steel or PPGI steel.It is made of cold rolled steel sheet and galvanized steel sheet, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), continuous coating (roller coating method), after baking and cooling.
A color coating steel plate from the section is divided into five layers: steel substrate, metal coating (also some products directly use cold rolled substrate), chemical conversion layer, primary (primer), finish (finish)
3.Advantages
Color coated steel is light and beautiful, with good anti-corrosion performance, and can be directly processed. It provides a new raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, furniture industry and electrical appliance industry, and plays a good effect of replacing wood with steel, efficient construction, energy saving and pollution prevention.

PPGI/PPGL Coils
Description
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.
Features
Broad Availability
Color steel sheet are available in wide range of colors, sizes, and mechanical characteristics.Color steel sheet with a PVC coating can be embossed, giving the finish a fine texture. Besides, color steel sheet are also available with PVC or PVF films with grain or leathery finish.
Outstanding Formability
The substrate of color steel sheet is heat treated in a continuous annealing furnace. It' s available in drawing, extra deep drawing, and lock forming grades. The tightly controlled hot dip process minimizes the formation of the brittle zinc-iron alloy layer, thus ensuring a firmly adhering zinc layer which doesn' t peel during forming. The color coatings are durable and flexible, thus they don' t peel during forming.
Excellent Cost Effectiveness
Color steel sheets are easy to use and have no need for post-painting, thus eliminating the need to invest in expensive labor, painting equipment, and pollution abatement costs. The extra durability of color steel sheets against corrosion and weathering, imparts a lasting application life and noticeably reduces maintenance costs. In the long term these features produce significant savings for the end user.
