Application scope of 406x140x39 steel h column
Low temperature environment
Applicable conditions: S355J0 material is particularly suitable for low temperature environment, and can still maintain at least 27J impact toughness at 0℃, while S355JR h type steel beam guarantees the same impact performance at 20℃.
Application scenarios: Such as polar research stations, cold storage buildings and other places where structural strength needs to be maintained under low temperature conditions.
High load demand environment
Applicable conditions: This type of H-shaped steel has a large cross-sectional size (height is about 406 mm, width is about 140 mm), and a weight of about 39 kg per meter, which can withstand high loads.
Application scenarios: For example, large industrial plants, heavy machinery support frames, core tube structures of high-rise buildings and other occasions with high requirements for bearing capacity.
Dynamic load environment
Applicable conditions: The good weldability and certain ductility of the S355 h shaped steel beam series of steel make it very suitable for dealing with dynamic loads.
Application scenarios: For example, the main beam or secondary beam position in bridge construction is still stable and reliable under traffic vibration or other forms of dynamic loads.
