On January 22, the space structure branch of China steel structure and association held the peak BBS of grid structure enterprises (including grid frame and shell structure) in xuzhou. The expert of branch of dimensional structure thinks, the steel structure of small span, net frame is inferior to light steel, but in engineering respect of large span steel structure, net frame wins out with the advantage such as dosage low, installation is convenient. Accordingly, industry of structure of structure of xu zhou new-style net still will continue to develop steadily.

In the face of the rapid development of the steel structure industry in xuzhou, the home of the grid has become an indisputable fact. Bigger and bigger; The larger the span; Look more and more new. 25 years ago, except feihong group, other steel structure enterprises in xuzhou gradually had comprehensive advantages in design, manufacturing and construction. Many projects become nationally known projects, "the township of the grid in xuzhou" has become an indisputable fact. Bolt ball processing diameter up to 1.2 meters, xuzhou China coal and steel structure company in 2007 contracted to build the huolinhe 200,000 tons of spherical grid storage bunker is known as "Asia's largest light steel grid storage bunker construction," won the gold award of the ministry of construction. Xuzhou feihong, jiangsu hengjiu, jiangsu tiandi, xuzhou anmeigu and other projects contracted by the construction, won the China construction "steel structure award".

With the continuous development of urban and rural construction, component resource-saving housing environment and reducing construction consumption have become the consensus in the industry. He said: "the advantages of the steel structure green energy-saving residential building system, first of all in line with the requirements of the circular economy. Steel structure is almost the only recyclable building structure system in China, which has many advantages such as good seismic performance, fast construction speed, and plays a significant role in saving resources and energy. He put forward, xuzhou each grid steel structure enterprises should integrate various technical advantages, as far as possible to achieve the design module, component standardization, processing factory, construction assembly, increase the cooperation with real estate business, to promote the development of China's residential steel structure building.

Call for the development of industry standards as soon as possible by virtue of the country's largest network frame and steel structure product production base, the advantages of the circulation base, the national network frame and steel structure quality inspection center was established in December 2007 in xuzhou, xuzhou has become another beautiful "city card". But the net frame profession has not the profession standard tardy, this has to be the profession one big flaw. Experts such as Dr. Li chengming, deputy director of the space structure branch, Dr. Geng xiaobing, deputy director of the technology center of Shanghai modern architectural design group, and geng xiaobing, deputy director of the naval engineering design bureau, proposed that the space structure branch and the quality inspection center should take the lead to develop the other side of the grid frame industry as soon as possible, so as to promote the sustainable and healthy development of the industry. Li Chengming, geng smile ice, such as thought, xuzhou the flying of rack company in steel structure processing, production, welding process, etc., do fine do ceaselessly, formed a complete set of strict technical operation procedures and quality management system, but if want to further development, to form the industry recognized set of rack industry standards and specifications. This is not only conducive to the development of xuzhou grid enterprises, the domestic industry as a whole has played a positive role.
