European Standard H-Beam

H-beams are an optimized development of I-beams, offering superior mechanical properties in cross-section and representing an economical type of section steel. They are named after their resemblance to the letter "H" in the English alphabet.

• Wide flanges provide greater lateral stiffness and bending resistance, approximately 5%-10% higher than that of I-beams.

• The parallel surfaces of the flanges make connection, processing, and installation more convenient.

• Compared to welded I-beams, H-beams have lower costs, higher precision, and less residual stress. They eliminate the need for expensive welding materials and weld inspections, saving about 30% of steel structure fabrication costs.

• Under the same sectional load, hot-rolled H-beam structures are 15%-20% lighter than traditional steel structures.

• Compared to concrete structures, hot-rolled H-beam structures can increase usable space by 6% while reducing structural weight by 20%-30%, thereby decreasing internal forces in structural design.

According to statistics, in the event of a devastating earthquake of magnitude 7 or higher, steel structures primarily composed of H-beams suffer less damage.
