Steel carport | Peng Jian steel (certified) | Dongguan City, Guangdong Steel by Peng Jian Steel Limited. Steel Co., Ltd., Dongguan City, Peng Jian (dgpengjian.cn) is specialized in the "Steel" business, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Xu. (1) a large number of steel sandwich quality issues that exist within the steel itself in the rolling process, has exceeded the national standard specifications, can be sent to verify the requirements of mills, steel mills in consultation with the return or exchange treatment; (2) if the number is less sandwich technology sector and the owners can seek advice, the information is fed back to the steel mills, the problems of the remedial measures taken by the construction of steel, according to the results of non-destructive testing, the use of the site in question All gouging away with more than the depth of their own, then with equal strength weld material filling, after the completion of the surface treatment, after a specified time NDT inspection of steel sheds, while members of the same physical and chemical sampling inspection, to You can continue to use the design specifications; (3) under the supervision of the witness parts cut off, back into the condition of the plate, replaced parts for non-load-bearing and non-critical parts or use as an auxiliary Guangzhou Steel structure of the company, after the completion of the specified time after NDT inspection, make a record. 1. The process of manufacturing operations to meet the requirements to ensure access and clearance operations. General prevailing net height of not less than 1.8M, the general should be set up around the platform guard railings, railing height is generally 1M. When the platform height is greater than 2M, there should be set up under the protective railing height 100-150mm 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 of the plane, elevation, beams grid and column grid layout in addition to meet the requirements, the arrangement of beams, columns, still should consider other large equipment loads and concentrated loads on the platform location and the large diameter industrial hanging pipes, etc; 3. the platform structure arrangement, should strive to be economically rational, clear direct force transmission. Beam grid layout should adapt its span. When larger span beams latest design of steel structures, the spacing should also increase. To allow full use of the plank span girder grid reasonable arrangement, in order to achieve better economic results.
