Prepainted steel coil

The color coated steel coil is manufactured by painting colorful Co ating materiais or by conglutinating organic flm on the basic sheeafter the proper surface treatment. Color coated steel coil has a lig ht weight, beautiful and good anti-corrosion performance, it can bedirectly processed, and also provides a new type of raw materials for construction, shipbuilding. automobile manufacturing, fumitureindustry, electrical industry, applicance:such as the steel instead of wood, such as 6 fficient construction, save energy and preventpollution. With the development of the industry, the wooden colo steel coll, camouflage color steel coil, transparent color steel coilhave also been stepping into and widely used by the market

PrePainted Steel Coils Structure



PrePainted Steel Coils Process


Appliciation Field

PPGL sheets and coils are widely used in many areas just like PPGI steel, including

1. Construction, such as roofing, wall panels, garages, ceiling, partitioning walls, etc.

2. Vehicle manufacturing industry, such as muffler, exhaust pipe, wiper attachment, fuel tank, truck box, etc.

3. Home appliances, for example, the panels of the refrigerator, washing machine, air conditioners, electronic microwave ovens, electrical cabinets, etc.

4. Agricultural uses, such as greenhouses, chicken coops, stables, haylofts, barns, sheds.




Difference Between PPGI And PPGL

1.PPGI is short for pre-painted galvanized steel, while PPGL is short for pre-painted galvalume steel. As the name suggests, PPGI uses galvanized sheets (with a layer of zinc coating) as base metal. While PPGL is with galvalume sheet as substrate, which is coated with 55% aluminum, 43.3% zinc, and 1.6% silicon. 



2. Al-Zn coating is more corrosion-resistant than zinc-coated steel sheet.

3.With the same weight, Al-Zn coating can cover 3% more space than the GI sheet.

4.PPGL has better corrosion and heat resistance than PPGI.
