Galvanizing refers to a surface treatment technology that coats the surface of metal, alloy or other materials with a layer of zinc for aesthetics and rust prevention. The main method used is hot dip galvanizing.

Galvanized sheets and electro-galvanized sheets are both iron alloy sheets that are coated with a layer of zinc on the surface of iron products to improve their corrosion resistance.

Color-coated steel coil, also known as color-coated steel coil, pre-coated steel coil or PPGI, is a kind of cold-rolled steel coil or galvanized steel coil that is coated with one or more layers of organic coatings on the surface, and then dried and cured. formed products. Color-coated rolls have good weather resistance, corrosion resistance and aesthetics, and are widely used in construction, home appliances, transportation, furniture and other fields. The price trend of color-coated rolls will be analyzed below.

With the continuous advancement of modern home appliance technology and consumers' increasing attention to product appearance and quality, color-coated steel coils are increasingly used in the field of home appliance manufacturing.

PPGI steel coil is a steel coil product treated with special coating technology. Compared with traditional coatings, it has many significant differences and advantages in appearance, durability and construction. This article will discuss the differences between color-coated steel coils and traditional coatings, and explain the advantages of color-coated steel coils.

The main influencing factors on the price of color-coated steel plates are raw materials (substrate) and zinc layer thickness, coating thickness, coating grade, steel coil thickness and packaging method.

The coating types currently used for PPGI/PPGL/PPAL steel coils include PE, HDP, PVDF, SMP, acrylic, PVC, etc.

SECC=Electro-galvanized steel sheet: Resistant to fingerprints, has excellent corrosion resistance, and maintains the processability of cold-rolled sheets.

Hot-dip galvanizing was developed from the older hot-dip method. It has a history of 140 years since France applied hot-dip galvanizing to industry in 1836.
