Compared with ordinary building boards, steel coils have stronger scratch resistance, and are not easy to leave scratches after being scratched by sharp objects, so they are often used to make home appliances and rolling shutter doors and windows.
In addition, because of their good weather resistance , and easy to form, it is also often used as a substitute for wood. Steel coil, also known as coil steel.
It takes slab (mainly continuous casting billet) as raw material, and after heating, it is made into strip steel by rough rolling unit and finishing rolling unit.
The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow, and is coiled into steel coils by the coiler.
The cooled steel coil, according to the different needs of users, is processed by different finishing lines to become steel plate, flat coil and slit steel strip products.
Because steel coil products have high strength, good toughness, and a wide variety of steel specifications, they are also widely used.
They are widely used from general engineering structures to the manufacture of automobiles, bridges, ships, boilers and pressure vessels.
