Galvanized color-coated coils and galvanized color-coated coils are widely used due to their various colors and good performance. However, many of them do not understand the difference. Let us introduce galvanized color coated coils and galvanized color coated coils.
Aluminum-zinc color-coated coil is a new type of material produced by domestic high-end technology in recent years, commonly called CCLI. It is made of galvalume steel (containing 55% aluminum, 43% zinc and 1.6% silicon) as the base material, and then after surface degreasing, phosphating and compound salt treatment, and then coated with an organic Paint and bake baked products. The corrosion resistance of galvanized steel sheet is better than that of galvanized steel sheet, generally: 5% NaCL 35℃, 1000Hrs, good electric field and no bubbles under 2mm. Therefore, the aluminum-zinc color coating coil and the galvanized color coating coil are essentially different in function.
In short, aluminum-zinc color-coated coils have better corrosion resistance, corrosion resistance and longer service life than galvanized color-coated coils. They are very suitable for construction and facility materials in harsh environments. At present, the development prospect of aluminum-zinc color-coated coils in the Chinese market is relatively optimistic, and will gradually enter more fields and get better applications.
Zhejiang Tiannu Color Steel Co., Ltd. was established in January 2003 and is located in Zhejiang Province. It is a Sino-Hong Kong joint venture with a registered capital of RMB 50 million. The company covers an area of 50,000 square meters, with a workshop area of 12,000 square meters.
The company's main products are hot-dip galvanized steel coils, Aluzinc steel coils, color-coated steel coils (ppgi/ppgl), color-coated aluminum coils, printed ppgi for household appliances, roof/corrugated ppgi sheets and ppgi coatings.
Currently, we have 85 skilled employees, 5 professional engineers and 15 experienced office personnel. The manufacturing capacity of our production line is nearly 100,000 metric tons per year.
