In emergency response, H-beam dimensions balance portability and structural integrity:
Compact Section Sizes:
Lightweight H-beams (HN150×75) with a height of 150mm and weight of 14.5 kg/m enable easy transport. The International Red Cross uses these beams to assemble 20m² shelters within 2 hours.
Interchangeable Components:
Standardized H-beam lengths (e.g., 6m) and bolted connections allow modular expansion. In earthquake-stricken Turkey, prefabricated H-beam kits increased shelter capacity by 50% in a week.
Load-Bearing Adaptability:
HN200×100 H-beams, with a load capacity of 15 kN/m², support multi-story relief structures. Bangladesh employs these beams to withstand monsoon winds (up to 120 km/h) in Rohingya refugee camps.
