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.

Hot-rolled steel coils, the backbone of infrastructure

  Hot-rolled steel coils, rolled at high temperatures, possess high strength and toughness, making them ideal for use in building materials and forming the structural foundations of numerous buildings and bridges. H-beams made from hot-rolled steel coils are the core material for bridge girders, easily withstanding the long-term and random impacts of passing vehicles.

Cold-rolled steel coils, a safety shield that balances aesthetics and practicality

  Cold-rolled steel coils, rolled at room temperature, offer high precision and a smooth surface, making them suitable for precision machining and stamping. They are commonly used in the bodies of vehicles such as high-speed trains and cars. After precision machining, these vehicles can effectively reduce wind resistance, improve fuel efficiency, and contribute to energy conservation, emission reduction, and carbon neutrality.

Galvanized and color-coated steel coils, excellent choice for exteriors of homes and appliances.

  In the home, steel inevitably encounters humid environments. Perhaps you've once fretted over an old washing machine rusted through, but now we have a better option: galvanized steel coil. This cold-rolled material, coated with a zinc coating, offers moisture resistance while retaining the smooth aesthetics of cold-rolled steel. Most kitchen appliances today are made of this material, significantly extending their lifespan.

 Color-coated steel coil, a decorative material with a built-in paint film, is now widely used on building exterior walls and roofs. It effectively blocks solar radiation, offers excellent water resistance, and maintains a low cost. If you choose a specially formulated, thickened, reputable paint film, color-coated steel coil can even withstand harsh environments for nearly 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.
