According to former State Planning Commission [No. 198611649 text "on please China Engineering Construction Standardization Committee responsible for organizing the recommended construction standard experimental work notice" requirement, now ratified Association standards "Arched corrugated steel roof structure Technical Specification", numbered CECS 167: 2004, recommended to the engineering design, construction, and use of adoption. No girder arch Waterproof: Galaxy roof structure catcher connection, without beam arch warehouse and joints will not be standing water in a section height, water seepage, and thus the structure itself waterproof impeccable. Junction with the lower edge of the roof beams are the weak link in the entire structural waterproofing, waterproof if handled properly, no girder arch, it will cause water seepage along the walls of the room, without beam arch canopy, while the water corrosion of steel and small joints embedded parts, the durability of the impact structure must pay attention to this part of the water treatment design. Usually two trioleyl flexible waterproof cloth. No girder arch, Guangxi Yinhe, no beam arch plant supplied by Guangxi Yinhe metal structure Engineering Limited. No girder arch, Guangxi Yinhe, without beam arch plant is Guangxi Yinhe metal structure Engineering Company Limited (www.gxmmr.cn) this year introduced a new upgrade, the above picture is for reference only, please call the contact or pictures on this page phone, for the latest information, contact: Mr. Sun.
