Steel Structure Buildings Main Technology

Smartweigh Instrument Co.,Ltd | Updated: Sep 29, 2017

Steel structure building a new kind of building system can connect the real estate, construction, metallurgical industry boundaries between the industry, set to become a new industry system, which is in the industry generally bullish on steel structure building system.

Compared with traditional concrete structures, steel structure buildings are replaced by steel plates or steel sections with reinforced concrete, with higher intensity and better earthquake resistance. And because the component can be made by factory, the site is installed, so the construction period is greatly reduced. Because of the reusability of steel, construction waste can be greatly reduced, which is more green and environmentally friendly. Therefore, it is widely adopted in the world and used in industrial buildings and civil buildings.

At present, the use of steel structure in high-rise buildings and supertall buildings is becoming more and more mature, which gradually becomes the mainstream building process, which is the development direction of future architecture.


1. Greatly economize construction time, construction is not affected by the season

2. Increase the use area of residential space and reduce construction waste and environmental pollution

3. The construction materials can be reused to promote the development of other new building materials industries

4. Good anti-seismic performance, easy to adapt and flexible in use, comfort and so on

5. High strength, light weight, high security and high degree of security, reduce building cost

6. In line with the national sustainable development strategy, low-carbon, green, environmental protection and energy conservation are among the key industries supported by the state


Due to the non-renewable land resources, the ministry of construction has banned the use of the traditional clay brick, at the same time, China's steel output reached 1 billion tons, the condition of serious supply exceeds demand has forced the iron and steel enterprises to introduce the foreign mature system of steel structure residential building, found a new way for construction and steel industry at the same time, as a result, steel mills and walk in the forefront of the steel structure residential building materials enterprises.

1. Heat resistant and not refractory, need surface coating for fire retardant coating

2. Easy to be corroded, surface need to be coated with anticorrosive paint, reduce or avoid corrosion, improve durable years

Energy conservation, efficiency, environmental protection and industrialization. After a few years of the 20th century, China's urban housing construction area of 440 million square meters, the completion of a year output value 600 billion yuan (about GDP9 %) for the construction of the rapid development of housing industry become a new growth point of national economy in the new century. To realize housing industry modernization, to resolve the existing in the construction of residential industrialization level is low, the product rate low and residential material grade, low service life, high energy consumption of the solid clay brick, is not conducive to environmental protection problems, has been included in the new century presses for solution of the problem. The construction industry in China requires the whole industry to study the new system of steel structure applied in various buildings, expand its application range and develop multi-layer steel structure buildings. Internationally, the designers and architects attaches great importance to the research of metal structure and its durability, practicability and economy, the European experts suggested that have the requirement of green building, steel structure is conducive to protect the environment, energy saving buildings. In their opinion, the dimensional feeling of metal structure has good can realize creative space planning and design, construction, not only is the live, use, more should consider is to create a more comfortable space, space of managing the sources of energy. In 1998, Japan produced 59 million tons of steel and 13 percent of the construction structure, while steel structures accounted for a significant proportion of steel structures, and Hong Kong was full of skyscrapers. The earthquake in Taiwan obviously shows that the steel structure is better than the reinforced concrete structure; Look from the earthquake damage, general multi-storey residential basic all fall to the ground, and steel structure building of housing not collapsed, so the Taiwan authorities wants multi-storey buildings are steel structures. The pilot of steel structure is used in multi-storey residential and small high-rise residential buildings in China, starting from tianjin. Tianjin adopts three different structures, different wall materials and different construction methods. We will launch a pilot project of more than 200,000 square meters. The first is the use of the large open structure of steel tubular columns; Secondly, the structure of steel truss structure is adopted. Thirdly, the structure of steel tube concrete is adopted. The square meters of three kinds of structures are less steel than the reinforced concrete structure. In Qingdao, Shanghai and New Territories, a certain area of housing projects will be piloted. Due to the current "steel housing" in our country, many structures cannot be mass-produced, so the steel structure will be more expensive than the concrete structure. Beijing Jin Chen calculated that the construction of the apartment unit, although the price of the overall structure of Shanghai is relatively high, but due to the short time, less energy consumption, high efficiency, quality class, so the comprehensive cost is not high, at the same time, because this is Beijing's first steel structure housing demonstration project, as a result, suppliers to the most preferential prices to provide the steel structure part, total cost and the concrete structure.
