H Beam is a kind of economic section of high efficiency with more optimized section area distribution and more reasonable strength-to-weight ratio. Because its section is the same as the English letter "H", it gets its name. Because each part of H-beam is arranged at right angles, h-beam has the advantages of strong bending resistance, simple construction, cost saving and light structure weight in all directions, and has been widely used.
An economic section shaped like the capital Latin letter H, also known as universal beam, wide flange (edge) I-beams or parallel flange I-beams. The cross-section of H-beams usually includes two parts, the web and the flange, also known as the waist and the edge. The inner and outer flanges of H-beams are parallel or nearly parallel, and the flanges end at right angles, hence the name parallel flanged I-beams. The web thickness of H-shaped steel is smaller than that of ordinary I-steel with the same high web, and the flange width is larger than that of ordinary I-steel with the same high web, so it is also named wide flange I-steel. Determined by the shape, the section modulus, moment of inertia and corresponding strength of H-beam are obviously better than that of ordinary I-beam with the same single weight. Used in different requirements of the metal structure, whether under bending moment, pressure load, eccentric load shows its superior performance, can be compared with ordinary I-steel greatly improve the bearing capacity, saving metal 10% ~ 40%. H-shaped steel has wide flange, thin web, many specifications and flexible use, which can save 15% ~ 20% of metal in various truss structures. Because the inner and outer flanges are parallel and the edge ends are right angles, it is easy to assemble and combine into various components, thus saving about 25% of welding and riveting work, greatly speeding up the construction speed and shortening the construction period of the project. Because of the advantages mentioned above, H-beam steel is widely used in: a variety of civil and industrial building structures; All kinds of 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 large bearing capacity, good cross-section stability and large span are required; Heavy equipment; Expressway; Ship frame; Mine support; Foundation treatment and dam works; Various machine components.
Shanghai Bosheng Industries Co., Ltd pays great attention to quality control and management. H Beam is completely controlled by iso9001-2008 quality system, and we have obtained the production license of railway products from The Ministry of Railways of China. We have a full set of testing equipment to ensure that all of our rail products meet customer requirements.
Shanghai Bosheng Industries Co., Ltd is an ISO 9001/2008 certified company. All processes are in accordance with the requirements of ISO quality management system, from supplier quality control to finished products, we are in accordance with the standard procedures, we have strict quality control system for suppliers:
1. Before producing H Beam, we will check and test the raw materials. we require suppliers to provide production batch number, chemical composition, mechanical properties and other testing indicators.
2. Our quality control inspectors take sample sampling and batch testing after the process of manufacturing H Beam, and provide raw material certificate and other means to control the testing process.
3.According to the different requirements of H Beam, we make the corresponding physical and chemical testing and inspection. If the results do not meet our requirements, we will refuse to accept the materials only if they meet our standards.
4. For semi-finished products and their external suppliers of H Beam, we often organize quality control coordination meetings and provide technical advice and guidance. Ensure that qualified products are delivered to our customers prior to shipment.
