Assembled steel multi-storey building with structural optimisation to reduce costs by 20%
According to the experience of Yuantai Derun, according to the division of assembled building structure system, it can be divided into precast concrete structure, steel structure and wood structure, compared with precast concrete and wood structure, steel structure has comparative advantages in many aspects. With the development of steel construction, the technology of assembled steel construction continues to mature, and assembled steel construction is widely used in offices, factories, warehouses, large public facilities and other fields, and one of the high-quality assembled steel multi-storey buildings is expected to become the future trend of residential buildings.
Continuous growth in the scale of assembled steel structures
According to the Ministry of Housing and Urban-Rural Development on the "Thirteen Five" assembly-type building action plan" clearly put forward, by 2020 the national assembly-type building accounted for more than 15% of new buildings, including key promotion areas to reach more than 20%, actively promote areas to reach more than 15%, encourage the promotion of areas to reach more than 10%. At present, China's actual assembled building accounts for only about 3% of new construction area, of which less than 1% is steel structure, with the policy level of the central and local continued promotion, China's assembled building penetration rate accelerated, the future of assembled steel structure building will have huge incremental space.

Innovative technology reduces structural costs by 20%
With the early development of concrete in China and its cost advantages, the development of steel housing has yet to produce economies of scale. At the same time, the development of assembled steel structures has brought with it higher standards and requirements for building support facilities. Although the cost of assembly is approaching that of cast-in-place from the data currently available, as an emerging method of building construction, many of the advantages of assembled steel buildings are incomparable to those of traditional buildings. Therefore, under the policy and its own characteristics, how to reduce the total cost of construction? Construction companies believe that it is more meaningful to promote assembled steel buildings through innovative technology to help them cost less.
Being an all-round service provider of structural steel pipes is the original intention of Yuantai Derun Innovation in developing steel pipes for assembly-type buildings. Since the establishment of the factory in 2002, Yuantai Derun has been conducting research and development in the field of structural steel pipes for assembly-type buildings, accumulating a large number of research results and innovative technologies, forming a variety of types of structural steel pipe product systems such as structural steel pipes for buildings, mechanical structural steel pipes and hot-dip galvanised structural steel pipes, most of which can be cost-competitive compared to traditional structural steel pipes. In addition to a large number of patents, the company's engineering experts have also participated in the preparation of several national codes for assembly-type buildings.
