Hot dip galvanized steel coils are commonly used in fields that require high corrosion resistance and strength, such as marine engineering, chemical engineering, shipbuilding, aerospace, etc., due to their excellent anti-corrosion performance and strength. In these fields, hot-dip galvanized steel coils can effectively resist the erosion of materials by harsh environments. Cold dip galvanized steel coils are commonly used in fields such as construction, home appliances, automobiles, and light industry. Although its anti-corrosion performance is not as good as hot-dip galvanized steel coils, its cost is relatively low and it can meet the anti-corrosion requirements in general environments.

Hot dip galvanized steel coil: The thickness of the galvanized layer is generally between 60-200um. Due to the high galvanizing temperature, the formed galvanized layer is more uniform and stable, thus having a longer service life. Cold galvanized steel coil: The thickness of the galvanized layer is between 5-15um, which is relatively thin. Although it can also provide some anti-corrosion effect, its anti-corrosion ability is weaker compared to hot-dip galvanized steel coils.

Galvanized steel coils, as an important steel product, have a wide range of applications in various fields. Its excellent performance and wide application prospects make galvanized steel coils an indispensable material in the manufacturing industry. With the continuous advancement of process technology and the increasing market demand, the development prospects of galvanized steel coils will be even broader in the future.

Galvanized steel coils are widely used in the manufacturing of household appliances such as refrigerators, washing machines, air conditioners, etc. Its surface is hard and flat, which can effectively protect the surface of household appliances and extend their service life. Galvanized steel coils are also used in the food processing industry, such as manufacturing conveyor belts, shelves, cargo boxes, etc. Its surface is smooth, corrosion-resistant, and meets food safety standards, ensuring food quality and hygiene.
