[Clouds Steel Works to recommend the star product - steel production] performance indicators 1, strength index strength of steel by the elastic limit σe, yield strength σy, and ultimate tensile σu, designed to yield strength of steel, based on the yield It can reduce weight, high strength structure Ganghunjiegou loft construction, save steel, reduce the cost. Σu tensile strength steel that is the maximum stress before damage can afford at this time due to plastic deformation of the structure and lost the use of a great performance, but the structure does not collapse deformation, structural resistance requirements to meet when severe earthquake. 'Σu / size σy value, can be considered parameters strength of steel reserves. [Clouds Steel Works to recommend Star Products - Steel production] 1, high strength material Ganghunjiegou loft company, its own light weight high strength steel, high modulus of elasticity. Compared to concrete and wood, the ratio of the density and yield strength is relatively low, so under the same conditions by a small force of steel under the member section, light weight, easy to transport and install, suitable for large span, high altitude, carrying heavy structure. Ganghunjiegou loft construction | Steel clouds (certified) | Ganghunjiegou attic from the Tianjin Jinghai clouds Steel Engineering Company. Tianjin clouds Steel Engineering Company (www.tjxygcfw.com) is Tianjin, steel leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Steel leadership in the clouds with the staff warmly welcome all inquiries negotiations to create a better future for steel clouds.
