AZ55 is the standard for galvanized steel sheets and coils used in a variety of applications, including roofing and siding. The AZ55 name refers to the thickness of the coating on the coil, which is between 0.375 and 1.5mm (0.015 and 0.059 inches).

AZ150 galvalume steel coil has a coating thickness of 18 microns on one side and 36 microns on both sides. The coating alloy of the steel consists of 55% aluminium, 43.4% zinc and 1.6% silica. This coating of steel acts as a passive barrier to general corrosion. It also helps protect steel from trimmed edges and scratches.

Galvalume steel coil is a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. So it is also known as cold galvanized steel.

PPGI coil is a popular material. It is based on hot-dip galvanized steel sheet or electro-galvanized steel sheet (galvanized layer) and is coated with multiple organic coatings to prevent it from rusting.

Color-coated galvanized sheet PPGL uses hot-dip galvanized sheet, electro-galvanized sheet as the substrate. It is coated with one or more layers of liquid coating after surface pretreatment and roller coating method. After baking and cooling, the surface has good weather resistance, superior processing performance and is rich in colors.

Wood grain color coated roll coil is made of refractory materials, such as steel and aluminum, which makes it an excellent choice for areas prone to wildfires or areas where fire safety is a concern. Unlike solid wood, wood grain board is not easy to rot, deform and crack. It also has strong resistance to impact and weather damage, which makes it ideal for harsh environments. Compared to solid wood, wood-like metals require minimal maintenance. It can be easily cleaned with a hose or high-pressure washer, and will not fade or discolor over time. Wood grain color coated roll coil products are widely used in construction, such as wall panels, siding, garage doors, fences, etc., and are also very popular in decoration and furniture.

Color-coated aluminum coils are the surface coating and coloring treatment of aluminum plates or aluminum coils. The commonly coated aluminum coils are fluorocarbon color-coated aluminum coils and polyester color-coated aluminum coils.

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.
