Hot-rolled high-strength, lightweight thin-walled H-shaped steel is a new type of steel product. Compared with ordinary hot-rolled H-shaped steel, it has the characteristics of “light and thin” while meeting the bending resistance. It is light in weight, saves metal, and improves bending resistance. Its yield strength, tensile strength, elongation, cross-sectional shrinkage and other force and energy parameters are better than those of the same type of high-frequency welded H-shaped steel.
Hot-rolled high-strength, lightweight, thin-walled H-beam is a new type of steel product. Compared with ordinary hot-rolled H-beam, it is “lighter and thinner” while maintaining bending resistance. Its light weight saves metal and improves bending resistance. Its yield strength, tensile strength, elongation, cross-sectional reduction and other mechanical parameters are superior to those of similar high-frequency welded H-beam. The main specifications are: H100×30×2.2×2.2 (American Standard), H101.6×57.2×2.35×3 (American Standard), H117×64×3.2×4 (American Standard), H100×42×2.2×2.5 (American Standard), H147×100×3.3×4.2 (American Standard W6×7), H148×100×4.3×5.5 (American Standard W6×8.5), H150×100×4.3×5.5 (American Standard W6×9), and H153×100×4.3×5.5 (American Standard W6×12). The ultra-thin H100×30×2.2×2.2 H-beam, developed and produced using Q500B steel, has a web thickness of only 1.8-2.2 mm, making it the lightest and thinnest ceiling product in the H-beam family. This series of high-strength, lightweight H-beam products has been widely used in applications such as trailer sills, high-end RVs, glass curtain walls, lightweight villas, centralized storage boxes, and photovoltaic mounting systems.
Materials typically include Q235B, Q355B, Q500B, and 20MnV, with standard lengths ranging from 6 to 9 meters.
