The Development Trend and Prospect of Steel Structure Construction Market

With the development of national economic construction, the situation of concrete and masonry structures is changing for a long time. Steel structure products in the long-span space structure, light steel gantry structure, multi-story and small high-rise residential areas of construction is increasing.

The application field is expanding from the construction practice of west-to-east gas transmission, south-to-north water transfer, Qinghai-Tibet railway, 2008 Olympic venue facilities, steel structure housing, western development and so on. Twenty years of reform and opening-up and economic development have created a very favorable development environment for the application of steel structure systems.

From the perspective of the main material foundation of the development of steel structures:

The development of steel is a key factor in the development of steel structures. In order to meet the needs of the construction market, finished steel will develop towards the standardization of a complete range of materials. The production capacity of hot-rolled H-shaped steel, colored steel plate and cold-formed steel has been greatly improved, creating important conditions for the development of steel structures. Other steel structures medium-sized steel, and coated steel plates have significantly increased, product quality has been greatly improved. Fire-resistant, weather-resistant steel, ultra-thin hot-rolled H-shaped steel and other new steel have begun to be used in engineering, creating conditions for the development of steel structures.

From the perspective of design, production and construction specialization:

After several years of development, the quality of professional steel structure designers has been constantly improved in practice. A group of characteristic and powerful professional research institutes and design institutes continue to research and develop steel structure design software and new technologies. At present, many domestic steel structure design software has been released one after another to meet the design needs of light steel structure, grid structure, high-rise steel structure and thin-walled arch structure. With the general application of computer technology in engineering design, steel structure design software functions are becoming more and more perfect to assist designers in completing structural analysis.

From the industrialization of residential steel structures perspective:

China has taken the promotion and application of light steel structures in residential construction as a revolution in the construction of high-tech industries. With the housing industry has become a new growth point for China's economic development, light steel housing will be the only way to develop the housing industry. The premise of housing industrialization is to have new technologies, new materials and new systems with industrialization. The steel structure system is easy to achieve industrial production, standardized production, and the accompanying wall materials can use energy-saving, environmentally friendly new materials. Therefore, the study of steel structure system residential technology will greatly promote the rapid development of residential industrialization.

From the guidance and support of government departments perspective:

The guidance and support of government departments make steel structures as green environmental protection products for workers and development. Compared with the traditional concrete structure, steel structure has the advantages of light weight, high strength and good seismic performance. Structures with a smaller ratio of live loads to total loads are more suitable for structures with large span spaces, towering structures and suitable for construction on soft soil foundations. It is also in line with the national policy of environmental protection, conservation and intensive use of resources.
