The development of building curtain wall in China is marked by the Great Wall hotel built in 1983, which has experienced nearly 40 years of development and evolution. From the lack of curtain wall concept and design standards to the mature application of various new technologies, new materials and new processes. Today, refined steel profiles, as curtain wall keel and beam, are gradually rising and popularized in the field of curtain wall.

Refined steel profiles have four basic characteristics.

First, the appearance of refined steel profile is comparable to that of aluminum profile. With a more slender size, it wins a wider and transparent space plasticity for the curtain wall. At present, in the commercial prime area with an inch of land and an inch of gold, more usable space can be saved on the basis of fixed area and space. With the increase of available space, curtain wall design can stimulate richer ideas and imagination.

Second, refined steel profiles have irreplaceable high strength. The steel profile has inherent excellent rigidity and is formed by refined steel rolling process. It not only has beautiful appearance, but also has several times the strength of ordinary steel. It not only has various shapes, large span and good permeability, but also can deal with it freely under the requirements of a variety of special-shaped and heterogeneous facades.

Third, the fabricated structure of Strong system is often adopted for refined steel profiles. All profiles are constructed in the factory. The project site only needs to assemble various parts like building blocks according to the drawings. Simple construction, environmental protection, fast speed and short construction period. Ordinary workers can be competent without special operators.

Fourth, refined steel profiles can use aerospace high-tech CPC graphene zinc nano coating system as the best anti-corrosion choice. Graphene zinc nano coating is a national patented product with an effective anti-corrosion life of up to 50 years. It is especially suitable for coastal areas, lakes, rivers, wetlands, chemical enterprises, large-scale engineering construction and other high saline and humid areas with harsh anti-corrosion environmental requirements and harsh natural conditions.

Refined steel profile is the inevitable trend of curtain wall development in the future. In the future, units using refined steel design and drawings will seize the market.
