Steel Coil: Witness to the Development of Human Society

  From the steel skeletons of skyscrapers to the metal packaging of canned goods, from the body frames of high-speed trains to the chassis of cars, these seemingly unrelated items all from a common base material: steel coils.

Infrastructure base of hot-rolled steel coils. Hot-rolled steel coils are well known for their strength and toughness as they are rolled at high temperature, formed the main building materials and a component for most buildings and bridges. 

The critical material for the core H-beam of every bridge girder is hot-rolled steel coils, which are resilient to the long-term and random effects of moving vehicles. 

Cold-rolled steel coils, a safety shielding design that strikes a good balance between aesthetics and function. The cold-rolled steel coils, when assembled at room temperature, provide high precision and a smooth surface for machining and stamping the surface to very nice looking. 

They can also find their applications in automotive bodies and high-speed trains. Using precision machining, such cars might minimize their wind resistance, improve fuel efficiency, aid in energy conservation, lower gas emissions and even help reach carbon neutrality. 

Galvanized and color-matched steel coils — perfect for home and appliance exteriors. Steel, as with all things, has to be in contact with damp environments at home. Perhaps you had been concerned a decade ago that a previous washing machine would rust, but we’ve got something better: galvanized steel coil. This cold-rolled coating on the steel, based on the zinc, makes the metal resistant to moisture while still maintaining the slick surface of cold-rolled metal. 

This material is probably used on most of the kitchen appliances that we get today, meaning that stuff just lasts a ton longer. Color-coated steel coil, is usually used in exterior walls and roofs of building nowadays. It effectively blocks solar radiation, it has remarkable water resistance and it has a minimal cost, if you choose a specially formulated and thickened, durable, reputable paint film, color-coated steel coil can handle the adverse environment and last for almost 20 years.

  Hot-rolled, cold-rolled, and color-coated steel coils are different forms of this material, each perfectly matching the specific needs of different industrial sectors. This material is becoming a designable industrial element, permeating every aspect of our lives and bearing witness to the development of human civilization.
