High frequency welded H-beams for construction engineering

H-beam is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength to weight ratio, named after its cross-section that is the same as the English letter "H".

purpose

H-shaped steel is widely used, mainly for various civil and industrial building structures; Various large-span industrial plants and modern high-rise buildings, especially in areas with frequent seismic activity and industrial plants under high-temperature working conditions; Large bridges with high load-bearing capacity, good cross-sectional stability, and large spans are required; Heavy equipment; expressway; Ship skeleton; Mine support; Foundation treatment and embankment engineering; Various machine components.

characteristic

The inner and outer sides of the flange of H-beam are parallel or nearly parallel, and the end of the flange is at a right angle, hence the name parallel flange I-beam. The thickness of the belly plate of H-beam is smaller than that of ordinary I-beam with the same height as the belly plate, and the width of the flange is larger than that of ordinary I-beam with the same height as the belly plate, hence it is also called wide edge I-beam. Due to its shape, the section modulus, moment of inertia, and corresponding strength of H-beams are significantly better than those of ordinary I-beams of the same weight. Used in metal structures with different requirements, it demonstrates superior performance in withstanding bending moments, pressure loads, and eccentric loads. It can greatly improve the bearing capacity compared to ordinary I-beams and save 10% to 40% of metal. H-shaped steel has wide flanges, thin web plates, multiple specifications, and flexible use, which can save 15% to 20% of metal when used in various truss structures. Due to the parallel inner and outer sides of its wing edges and the right angled edge ends, it is easy to assemble and combine into various components, which can save about 25% of welding and riveting work, greatly accelerate the construction speed of the project, and shorten the construction period.
