Section steel hot-rolled section steel processing section steel company galvanized section steel manufacturer_Find Shanghai Ruiling ◆ Whether I-section steel is ordinary or light, due to the relatively high and narrow cross-section size, it has a negative impact on the moment of inertia of the two main sleeves of the section The difference is large, so it can generally only be used directly for components that are bent in the plane of their webs or formed into lattice-type stressed components. It is not suitable to use axial compression members or members that are perpendicular to the web plane and are curved, which greatly limits its application range.
◆Shaped steel is an efficient and economical section profile (others include cold-formed thin-walled steel, profiled steel plate, etc.). Due to their reasonable cross-sectional shape, they can make the steel more efficient and improve its load-bearing capacity. Different from ordinary I-shaped ones, the flange of the section steel is widened, and the inner and outer surfaces are usually parallel, which makes it easy to connect with other components with high-strength bolts. Its size series is reasonable and the models are complete, which is convenient for design and selection.
◆The flanges of section steel are all of equal thickness, with either rolled sections or combined sections composed of welded plates. I-beams are all rolled sections. Due to poor production technology, the inner edge of the flange has: slope. The rolling of section steel is different from that of ordinary I-beams that only use one set of horizontal rollers. Because its flange is wide and has no slope (or has a very small slope), a set of vertical rollers must be added for simultaneous rolling. Therefore, Its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled steel sections that can be produced in China is , and beyond that can only be welded combined sections. my country's national standard for hot-rolled steel sections (B) divides section steel into three categories: narrow flange, wide flange and steel pile. Their codes are respectively, and. Narrow flange steel is suitable for beams or compression members, while wide flange steel and steel piles are suitable for axial compression members or compression members. Compared with section steel, under the premise of equal weight, I-beam, , and section steel are not as good as section steel.
Shanghai Ruiling Construction Steel Structure Engineering Co., Ltd. was established in 2001. It is mainly engaged in the production, processing, sales and after-sales service of section steel, section steel and other section steel. The company has a team of senior engineers, senior technicians, steel structure designers and A professional engineering and technical team composed of professional steel structure installers, mainly undertakes projects such as large-scale steel structure workshops, steel structure warehouses, steel structure platforms, steel structure residences, steel structure mobile homes, sun rooms, steel structure lofts, steel structure carports and rain sheds, etc. After nearly two decades of development, Ruiling Company has become one of the most professional steel structure companies in East China.
