The best steel manufacturers, Peng Jian steel (certified), Zhuhai, Dongguan Peng steel structure built by Steel Limited. Steel Co., Ltd., Dongguan City, Peng Jian (dgpengjian.cn) is specialized in the "Steel" of the enterprise, the company adhering to the "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Xu. Steel Engineering is mainly structural steel production steel prices, is one of the main building structure types. Steel is one of the more common modern construction projects in the form of structure. Ours is the first manufacturer with a national iron bearing structure, much in the era of Qin Shi Huang (246-219 BC), the would have to do a simple load-bearing structure with iron, while Western countries began to use metal load-bearing structure in the 17th century. 3-6 century AD, steel, smart and hard-working people of our country on the iron chain suspension bridge built with chains, the famous chain bridge Dadu River in Sichuan Luding, Yunnan and Guizhou Yuan River Bridge River Bridge are all early iron plate body of the load-bearing structure Examples. 1. Meet the requirements of process manufacturing operations to ensure the passage and clearance operations. General prevailing net height of not less than 1.8M, around the platform shall be provided with protective railings general steel metal housing, railing height is generally 1M. When the platform at a height greater than 2M steel manufacturers, there should be set at a height of 100-150mm protective railings skirting boards. Platform should be set for the upper and lower prevailing ladders width of not less than 600mm. 2. Determine the size of the platform structure plane, elevation, beams grid and column grid layout in addition to meet the requirements, the arrangement of beams, columns, still should consider equipment loads and concentrated loads of other larger location on the platform as well as large-diameter industrial hanging pipes, etc; 3. the platform structure arrangement should strive to be economically rational, transfer directly clear. Beam grid layout should adapt its span. When larger span beams, the distance should also increase. Allows full use of decking span, rational arrangement of beam grid, in order to achieve better economic results.
