Galvanized steel coils are made by hot-dip galvanizing on the surface of cold-rolled steel coils. Hot-dip galvanizing is a treatment process that uses the good corrosion resistance of zinc to immerse the steel plate in molten zinc liquid to form a layer of zinc on its surface. This processing method not only has an aesthetic effect, but also has the function of preventing steel from rusting.
Cold-rolled steel coils are steel processed by cold rolling. By controlling the temperature, pressure and other parameters of the cold rolling process, the surface of the steel is smooth and has high strength, high wear resistance, and corrosion resistance.
Galvanized steel coils have the following advantages.
Anti-corrosion hot-dip galvanizing can prevent oxidation of the steel surface, extend the service life, and keep the steel surface at a certain gloss.
The surface of the galvanized steel coil has a bright gloss, and the appearance is more beautiful and generous.
Galvanized steel coils can not only be used in the construction field with high requirements for appearance, but also as liquid or gas storage and transportation pipelines.
Cold-rolled steel coils have the following advantages.
Cold-rolled steel coils are processed by cold rolling process, and the surface of the material is uniform and smooth, with high strength and hardness. It is a high-strength and high-precision steel.
Cold-rolled steel coils have good plasticity and processability, and can be processed by mold stamping and other processes, and have a wide range of applications.
After the cold rolling process, the surface performance of cold-rolled steel coils is more stable and more wear-resistant.
Because galvanized steel coils have good corrosion resistance and aesthetics, they are widely used in construction, manufacturing and other fields, such as building roofs, wall panels, steel structures, automobile panels, home appliances, etc.
In the fields of machinery, electronics, etc., cold-rolled steel coils are often used as raw materials for the manufacture of various parts and equipment. In addition, cold-rolled coils can also be used as raw materials for the manufacture of boilers and automobile manufacturing.
Galvanized steel coils and cold-rolled steel coils are different types of coils in steel processing. Galvanized coils mainly have the characteristics of corrosion resistance and beauty, and are used in the fields of construction, manufacturing and other fields. Cold-rolled steel coils have the characteristics of high strength and high wear resistance, and are widely used. They are often used as raw materials for the manufacture of various parts and equipment in the fields of machinery, electronics and other fields.
