UB 610x305x238 h beam steel: height is 610mm, flange width is 305mm, and the theoretical weight per meter is 238kg.

GNEE is usually produced by hot rolling process. After the steel is heated at high temperature, it is subjected to strong plastic deformation in the rolling mill to obtain the required cross-sectional shape and size. In some cases, we may perform normalizing treatment. After the steel is heated to a certain temperature, it is naturally cooled in the air to eliminate internal stress and improve the organizational properties.

Construction field: It can be used to manufacture frame structures, support structures and roof structures of high-rise buildings, commercial buildings and residential buildings.

Bridge construction: Its high strength and good toughness enable bridges to withstand the effects of natural forces such as earthquakes and wind loads, ensuring the safety of bridges.

Vehicle manufacturing: It is widely used in the manufacture of vehicle frames, bodies and other components, with the characteristics of high strength and light weight.
