Application areas
Building structure: HEA140 h type beam is suitable for light factory frame and bridge auxiliary support; HEB140 h section beam is suitable for medium-sized industrial factory main beam and warehouse load-bearing column.
Machinery manufacturing: heavy equipment bracket (such as mining machinery base); ship deck reinforcement or bulkhead support.
Special scenarios: outdoor structures that need to adapt to low temperatures of -20℃ (relying on S275JR low-temperature toughness); prefabricated steel structures produced in batches in a standardized manner.
Economic efficiency and selection recommendations
HEA140 h-shaped iron beam: suitable for light-load scenarios, lower cost and easy to carry;
HEB140 h-shaped steel beam: has a stronger load-bearing capacity and is suitable for the main load-bearing structure. The unit price is slightly higher but the overall benefits are significant.
