Guangzhou Steel News: steel structure to carry out the construction market trends and outlook
Because of its light weight steel construction system itself has high strength, fast construction and other strengths, compared with reinforced concrete structure, but has a "high, big, light" to carry out the three aspects of the unique advantages. With the development of national economic construction, concrete and masonry construction has long been the situation in a unified world is changing. Commodity steel structure built in large span space structure light steel gantry structure, multi-field, and the growing number of high-rise residences, expanding use of the area. From the West-East Gas, West, East lose, water diversion, the Qinghai-Tibet Railway, the 2008 Olympic Games venues and facilities, steel structure residence, western development and other construction practice, one to carry the momentum of construction steel construction industry and markets is China is seeing.

First, carry out construction steel market trends
Two decades of reform and opening up and economic development, has invented a very favorable environment for the use of steel structure to carry out the system.
1, from the material basis for the main steel structure to see:
Steel is a key factor to carry out steel construction undertaken. In order to meet the needs of the construction market, the steel products will move towards complete standardization of materials to carry out the direction of varieties. Domestic construction steel construction steel in the number, variety and quality are carried out quickly, hot-rolled H-shaped steel, color steel, cold-formed steel production capacity has greatly improved for the steel construction of the important conditions to carry out the invention. Other steel structure in steel and painted galvanized steel sheet has significantly increased, product quality has improved greatly. Fire-resistant, weathering steel, ultra-thin hot-rolled H-beam steel and a number of new projects has begun in the use of steel construction to carry out the invention conditions. Guangzhou Steel
2, from the planning, production, construction level professional look:
Steel construction industry after several years to carry out, the quality of professional steel structure planners constantly improve in practice. A number of characteristics of powerful professional institutes, the Planning Institute of continuous research and development of the steel construction planning software and new technologies. Now, many domestic steel construction planning software one after another, can be individually adapted to planning needs light steel structure, the grid structure, high-rise steel structure, thin-walled vaulted structure. With the widespread use of computer technology in project planning, improving steel construction planning software functions to assist planners complete structural analysis planning, construction drawings provides a great convenience.
Steel structure manufacturing enterprises everywhere in the country, creating a number of powerful enterprises. 10 - 20 million tons of annual output reached more than 10 enterprises have the scale, bear a large domestic steel structure engineering tasks, they are fully equipped to compete fairly with the international strength of enterprises in the same industry. Now a number of foreign investment, joint ventures, private institutions of steel manufacturing companies have come to the fore in the fierce competition in the market. From computer programming, graphics, digital control, automation manufacturing are in industry-leading level, the scope of its merchandise from the traditional construction engineering construction, machinery and equipment, non-standard components, complete sets of facilities to commodity houses, container trade, port facilities and other direct to the user's terminal products.
Industrialized mass production of steel construction, steel construction work to install a new law after another, as well as energy-saving, water, insulation, and other advanced products mobilized and integrated sets, planning, construction and integration of production will improve the level of industrialization of construction.
3, from the steel structure engineering performance point of view:
Across the Yangtze River Transmission height of 421 meters the world's third of Shanghai Jinmao Tower, a leading international level, the height of 279 meters in the Shenzhen SEG building, span 1490 m Runyang Yangtze River Bridge, span 550 meters of the Lupu Bridge, the 345-meter Many important projects of steel structure construction system of the Eiffel Tower, as well as the Capital International Airport, the Bird's Nest National Sports Center, etc., marking the construction of high-rise steel structure forward heavy and space to carry out large-span steel structure.
4, from the residence of the steel structure industrial point of view:
Promote the use of light steel structure of 已把 on residence building as the construction of a revolution in the industry. With the economic development of home industry to become a new growth point, light steel shelter will be the only way to carry out home industry. The residence industrialization and industrialization premise is matched with new technology, new materials and new systems. As the steel construction system is easy to implement industrial production, standardized production, and with the support of the wall materials can be used energy-saving, environmental protection, new materials. Therefore, the study of steel construction system shelter set of technologies, will greatly facilitate the rapid industrialization of the residence to carry out.
5, from the guidance and support of government departments to see:
Guidance and support of government departments, the steel structure as green goods get workers and conduct. Steel structure with traditional concrete structure, compared with a light weight, high strength, good seismic performance advantages. Suitable for live loads smaller proportion of the total load configuration, more suitable for large-span space structure, and is suitable for high-rise structures built on soft ground. Also in line with environmental protection and saving and intensive use of resources of national policy, increasing its overall economic benefit for the parties to investors. Guangzhou Steel
