Durable Steel Structures for Large-Scale Projects | Junyou Steel

Steel H beams from Guangdong Junyou Steel Structure Co., Ltd are foundational structural components, named for their H-shaped cross-section, which balances strength and weight efficiency. Manufactured from high-grade steel (Q235, Q355, or Q690), these beams feature flanges (horizontal sections) and a web (vertical section) that work together to resist bending and shear forces, making them ideal for load-bearing applications in buildings, bridges, and industrial facilities. Key specifications include: - Sizes: Flange widths 100-600mm, web thickness 6-30mm, lengths up to 12m (custom lengths available). - Strength: Yield strength 235-690MPa, enabling spans up to 20m in commercial buildings. - Applications: Primary columns/beams in high-rises, bridge girders, crane runways (supporting 50+ ton loads). Fabrication involves hot rolling for uniformity or welding for custom sizes, with strict dimensional checks (±1mm). Surface treatments—zinc plating or epoxy coating—resist corrosion, extending service life in humid/coastal areas. These beams integrate seamlessly with other steel components via bolted/welded connections, ensuring structural rigidity. Used in projects like airports and factories, steel H beams reduce material usage by 20% compared to I-beams, offering cost savings without compromising performance. The company’s H beams comply with GB/T 11263 and ASTM A6, meeting global standards for reliability.
