H-beam is an economic and efficient section steel with a cross-sectional shape similar to the uppercase Latin letter 'H', also known as wide-flange I-beam. Here are its detailed introductions: Characteristics: High Structural Strength: Compared with ordinary I-beams, H-beams have a larger section modulus. Under the same loading conditions, they can save 10%-15% of metal and greatly improve bearing capacity. Easy Construction: The flanges are parallel inside and outside, and the flange ends are at right angles, facilitating the assembly and combination into various components, which can save about 25% of welding and riveting work, accelerate the construction speed, and shorten the construction period. Good Stability: Since all parts are arranged at right angles, it has strong bending resistance in all directions, high structural stability, is suitable for building structures that bear large vibration and impact loads, and has strong resistance to natural disasters. Space-saving: Compared with concrete structures, H-beam steel structural columns have a smaller cross-sectional area, which can increase the effective usable area of buildings by 4%-6%. At the same time, the bay of steel structures can be 50% larger than that of concrete structures, making building layout more flexible.
