in the industrial field.

With the expansion of investment scale in strategic emerging industries such as “new infrastructure”, UHV construction and 5g base station construction involving steel structure demand will bring potential growth demand to the steel structure industry.

The growth rate of national industrial added value is stable.

Modern high-speed railway construction requires high impact resistance and high flatness of subgrade.

The plan proposes to vigorously promote the application of precast buildings, actively promote the construction of high-quality steel structure residential buildings, encourage schools, hospitals and other public buildings to give priority to the use of steel structures, and cultivate a number of precast construction production bases.

Foreign low rise light steel housing system has been relatively mature.

The types and application fields of equipment steel structures are very wide, which are mainly used in special buildings, equipment racks and supports (such as cement kiln tail, power and communication tower), boiler steel frames (power boiler and other boiler towers), special equipment towers (oil pipelines, offshore platforms, port equipment, chemical equipment), etc.

China’s steel output ranks first in the world all year round, and the supply of steel is stable.

In fact, in recent years, the state and local governments have intensively issued a number of policies to promote the development of precast buildings, and steel structures will greatly benefit from the development of precast buildings.

The downstream of steel structure is widely used in industries and construction industries such as plant storage, multi-storey and high-rise buildings, venues and power bridges.

There is no unified standard for the classification method of steel structure.

There is still a large space for China’s urbanization construction (from the development experience of other countries in the world, after the per capita GDP reaches 10000 US dollars and the urbanization rate reaches 60%, there will be at least 10 to 15 years of rapid urbanization development period).

↑ click “Guorui construction technology” above to pay attention to our recent release of the “14th five year plan” for the development of construction industry.

In terms of steel structure housing, the level of China is far from that of developed countries.

According to the application field, it can be divided into five categories: equipment steel structure, building heavy steel structure, building light steel structure, bridge steel structure and space steel structure.

Its price fluctuation will directly affect the profitability of steel structure enterprises.

The market process is simple, there are many manufacturers, the market competition is more intense, and the gross profit margin of products is lower.

With the continuous improvement of the market’s recognition of equipment steel structure, the application of equipment steel structure is expected to continue to grow.

Among them, light steel structure is mostly used in plant storage.

In addition, China’s steel enterprises also pay attention to the demand for steel in steel structure, and actively develop corrosion-resistant steel to boost the development of steel structure.

More than 90% of the steel structure buildings built in Japan are low-rise buildings with 5 floors or less.

From the perspective of enterprise types, the industrial chain of steel structure includes upstream steel suppliers, midstream steel structure enterprises and downstream engineering enterprises; From the business type of steel structure, from upstream to downstream, it can be roughly divided into three links: design, manufacturing and construction.

Recently, domestic new high-speed railways mostly adopt elevated design, and steel structure is used as the main structure of elevated bridge.

Equipment steel structure equipment steel structure is an important branch of heavy equipment manufacturing industry.

Compared with other structural forms such as reinforced concrete structure, masonry and other masonry structures, steel structure not only has many advantages such as high strength, light weight, good plastic toughness and seismic performance, but also is suitable for mechanized processing, high degree of industrialization and short construction period.

Building light steel structure building light steel structure is mainly used in light industrial workshop, steel structure residence, etc.

Due to the little use of cement, gravel and other materials, the environmental pollution problems such as dust, construction waste and noise are greatly reduced, which meets the requirements of sustainable development.

The United States, Japan, Australia and other countries have already widely used light steel structure in low rise housing.

Steel structure is a form of building structure mainly composed of steel plates, section steels, steel pipes, steel cables and other steels connected by welds, bolts or rivets.

China’s investment in railway, highway, bridge and other transportation infrastructure fields will greatly promote the development of bridge steel structure, and the market demand of bridge steel structure will increase significantly in the next few years.

H-section steel and medium and thick plate are the most commonly used products in steel structure.

The development speed of industrial factory buildings is closely related to the scale of industrial development.

The upstream of steel structure is the steel industry, and the main raw materials are plates, profiles, steel pipes and other steel products.

The development speed of equipment steel structure is closely related to the speed of industrial development.

High-rise heavy steel structure, long-span spatial structure, power bridge and other fields belong to high-end products.

The development of China’s national economy shows a good trend of sustained and stable growth, with certainty.

The application of steel structure in the field of industrial plants will maintain a trend of sustained growth.

In terms of price, steel procurement accounts for about 50 ~ 80% of the production cost of steel structure, and the steel price directly affects the profit of steel structure.

In Australia, the market share of light steel structure housing is 15%, and row steel structure housing has also been used in some parts of Europe.

It is expected that the market demand for equipment steel structure will maintain a stable development space in the future.

Bridge steel structure road traffic market has great demand for steel structure in the fields of railway, highway, urban transportation and bridge.

The production raw materials of steel structure are mainly steel plate, welded pipe, section steel, seamless steel pipe and other steel products.

Building heavy steel structure steel structure accounts for more than 85% of foreign buildings with a height of more than 200m.

During the 14th Five Year Plan period, China’s urbanization construction will better support the demand of urban public buildings for high-rise heavy steel structures.

According to the statistical bulletin on the development of transportation industry from 2011 to 2019, the average annual compound growth rate of China’s highway construction investment scale from 2011 to 2019 is 7.2%; In terms of railway, since the construction of “four vertical and four horizontal” railway rapid passenger transport channel and three intercity rapid passenger transport systems have been started one after another, China’s railway construction has entered the stage of rapid development of high-speed railway; High speed railway infrastructure projects mostly use steel structure viaduct as subgrade, and railway infrastructure investment will also tend to choose steel structure bridge project..

The United States and Japan are the countries with the most steel structures in high-rise buildings.
