Comparison between UB 203x133x25 h-shaped iron beam and UB 203x133x30 h-shaped beam:
The web and flange of the 30 model are thicker, the weight is increased by about 20%, and the bearing capacity and bending resistance are stronger; the 25 model is lighter and suitable for scenes that are sensitive to weight but not extreme in load requirements; the cross-sectional dimensions (height and width) of the two are basically the same, and the interchangeability is high.
Application of 203x133x25/30 UB H-beam made of S355JR
Building structure: used as beams and columns to support factories, high-rise buildings, stadiums, etc.; cross-section optimization design reduces the weight of the structure by 30-40% (compared with traditional I-beams).
Bridge engineering: load-bearing components such as bridge decks and beams; high strength and toughness ensure long-term stability.
Machinery manufacturing: basic frames for cranes and transportation equipment; easy to process and assemble, reducing welding workload by about 25%.
Ocean and energy engineering: wind power towers, offshore platform support structures (need to cooperate with anti-corrosion treatment).
Others: equipment foundations, brackets, foundation piles, etc., to meet high load and stability requirements.
