Q390GJB Q390GJC Steel Beam H
Q390GJB high performance steel for building structure is referred to as high construction steel, which has the properties of easy welding, earthquake resistance, low temperature impact resistance, etc. It is mainly used in high-rise buildings, ultra-high-rise buildings, large-span stadiums, airports, convention and exhibition centers, as well as steel structure plants and other large-scale construction projects.
Compared with plain carbon or low alloy steel, the yield strength of high-built steel sets an upper limit, the tensile strength has improved, and there are requirements for carbon equivalent and flexural strength ratio indexes. High-construction steel is usually produced by medium plate mill, but it is not excluded to be produced by furnace coil mill and hot strip mill unit.
Q390GJC h steel profile belongs to the steel for building structure, referred to as high construction steel, is a low alloy high-strength steel.Q390GJC is suitable for the manufacture of high-rise building structures, large-span structures and other important building structures.
Q390GJC h profile steel is mainly used in high-rise buildings, ultra-high-rise buildings, large-span stadiums, airports, convention and exhibition centers, as well as steel structure plants and other large-scale construction projects.
Q390GJC h type beam through the application of high construction can greatly adapt to and support the direction of the development of building structure to high-rise and large-span, in order to reduce the weight of the structure, reduce the cost of manufacturing, reduce the thickness of the steel structure material, and improve its manufacturing reliability.
