Second, the supply forecast of China's steel structure industry from 2022 to 2026

Driven by a series of major events such as the Winter Olympics, the development momentum of the steel structure industry will be more violent, and a large number of spectacular, iconic and exquisite steel structure projects are constantly posing new challenges to China's steel structure manufacturing industry. These famous projects will promote the future trend of China's steel structure industry will be better. In the next few years, China's steel structure industry will continue to maintain a rapid growth trend, and the prospect of the steel structure industry is promising.

In China, the development and application of steel structure buildings lag behind foreign countries. Since the cost of steel structure buildings is slightly higher than that of concrete buildings, the use of steel structures in China is mainly high-rise buildings, public buildings and other large buildings, and steel structure houses are still relatively few. With the progress and development of modern society, the application of steel structure is becoming more and more extensive. In the construction project, the expansion of the scale of construction, the use of steel structure is becoming more and more common, especially the opening of China's national door, the increasingly frequent foreign exchanges, steel structure buildings have achieved rapid development.

Third, 2022-2026 China's steel structure industry demand forecast

Under the background of double carbon and the development of China's construction industry, the requirements for building structural performance are also getting higher and higher. In order to respond to the call of China's sustainable development strategy, China has developed a light steel structure and is widely used in construction projects. Light steel structure is widely used in domestic industrial, agricultural, commercial and residential buildings due to its steel-saving, safe and reliable, construction period saving and flexible use, and the use of light steel structure buildings has been recognized by the society and has become an important part of steel structure buildings.

Section 2022 Development prospects of steel structure market from 2026 to <>

First, the development potential of the steel structure market from 2022 to 2026

At present, the steel used in China's steel structure industry only accounts for about 5% of the total steel in the country, and there is a big gap with the proportion of about 10% in developed countries. Domestic steel can basically meet the needs of steel structure processing, but there is still a gap with foreign countries in terms of specific varieties, specifications and performance, such as high-strength large-specification ultra-thick H-beam steel, high-strength ultra-thick plate, etc. At present, Japan promotes the use of strength Q690 grade steel in construction and bridges, and has matured the use of Q960 mechanical steel.

In the future, the variety, quality and specifications of domestic steel should not only meet the needs of domestic and foreign steel structure development, but also lead the international leadership in the application and development of high-performance steel in related fields; Steel structure products, accessories and supporting technology products have reached the international advanced level. Focus on the potential market and independent innovation technology development of steel structure housing, steel structure bridges and non-standard, complete sets of equipment manufacturing (including new energy wind power, nuclear power, smart grid, three-in-one, marine engineering steel structure network, etc.) with a large amount and wide range of output value, promote the overall improvement of the quality of steel structure house construction, improve the service life and actual life of buildings more advanced, promote the improvement of related supporting products and components, and gradually make the steel structure industry a strategic emerging industry in China. It initially has the goal of strengthening the country with steel and steel structure.

Second, the development prospect of steel structure market from 2022 to 2026

In the future, the development of China's steel structure will focus on offshore oil engineering equipment, steel structure housing, steel structure bridges and other three fields, such as the country's 3,59 highway bridges as an example, the current steel structure bridges are less than 1%, and steel structure bridges account for 41% in Japan, the United States accounts for 33%, it can be seen that China's steel structure bridge market demand, industrial development and developed countries still have a big gap. The National Development and Reform Commission, the Ministry of Industry and Information Technology, and the Ministry of Science and Technology are also studying the determination and planning targets of strategic new industries, and will include them in the planning and give support and support policies to industries with international advanced level, strong independent innovation ability, strong international competitiveness and can occupy more markets. Opportunities are also challenges, whether China's steel structure industry can go up the ladder and scale, the development of the past ten years is crucial.

（1） Fundamentals The foundation is a component of a building, which is a load-bearing component below the ground level. It supports all the loads of the upper building and transmits these loads and the self weight of the foundation to the foundation below. The foundation must be sturdy, stable, and reliable. [1] （2） Foundation The foundation is not a component of a building, but a soil or rock mass that bears the load transmitted from the foundation. The building must be built on a solid and reliable foundation. To ensure the firmness and stability of the foundation and prevent accelerated or uneven settlement, the foundation should meet the following requirements: having sufficient bearing capacity and uniform compression to ensure uniform settlement; Has the ability to prevent landslides and inclinations. [1] （3） Wall Walls and columns are vertical load-bearing components that support roofs, floors, and transmit these loads and self weight to the foundation. The functions of walls include load-bearing, maintenance, separation, and decoration. The requirements for walls are: sufficient strength and stability; Meet the performance of thermal engineering (insulation, insulation, and prevention of condensation water); Having certain sound insulation performance; It has certain fire resistance performance. Walls have different names according to different classifications, mainly including the following categories. 1. It is divided into exterior walls and interior walls according to its location in the building. External wall: The external wall is located around the building and serves as a maintenance component, serving as a wind, rain, thermal insulation, sound insulation, and other functions. Internal wall: The internal wall is located inside the building and mainly serves to separate the internal space, as well as to provide sound insulation, fire prevention, and other functions. 2. Divided into longitudinal walls and transverse walls according to their orientation in the building. Vertical wall: refers to a wall arranged along the long axis of a building. Horizontal wall: refers to a wall arranged along the short axis of a building, with the outer horizontal wall commonly referred to as a gable. 3. Divided into load-bearing walls and non load-bearing walls according to their stress conditions. Load bearing wall: refers to a wall that directly bears the load transmitted from beams, floors, roofs, etc. Non load-bearing wall: refers to a wall that does not withstand external loads. In non load-bearing walls, walls that only bear their own weight and transmit it to the foundation are called load-bearing walls; A wall that only serves as a partition space and its own weight is borne by the floor slab or beam is called a partition wall; In frame structures, walls do not bear external loads, and the walls between filled columns are called filled walls; A wall composed of lightweight wall panels suspended outside a building for decorative purposes is called a curtain wall. 4. According to the materials used, it is divided into brick walls, stone walls, small block walls, and reinforced concrete walls. 5. Divided into solid walls, hollow walls, and composite walls according to their structure. Solid wall: A wall built with clay bricks and other solid blocks. Hollow wall: A wall with cavities inside it, which can be formed by building blocks or by combining materials with holes, such as hollow blocks. Composite wall: refers to a wall composed of two or more materials, such as an aerated concrete composite panel wall.

1. Brick and wood structure building: The main load-bearing components of this type of building are made of brick and wood. The walls and columns of the vertical load-bearing components are made of brick, while the floors and roof trusses of the horizontal load-bearing components are made of wood. The number of floors in this type of building is generally low, usually below 3 floors. Ancient architecture and buildings from the 1950s and 1960s often have this type of structure. 2. Brick concrete structure building: The vertical load-bearing components of this type of building use brick walls or brick columns, and the horizontal load-bearing components use reinforced concrete floors and roof slabs, including a small number of roofs using wooden frames. The number of floors of this type of building is generally below 6, with low cost and poor seismic resistance. The width, depth, and floor height are all limited. 3. Reinforced concrete structure building: The load-bearing components of this type of building, such as beams, slabs, columns, walls, roof trusses, etc., are composed of two major materials: steel bars and concrete. Its enclosure components such as walls and partitions are made of lightweight bricks or other masonry. The characteristics are strong structural adaptability, good seismic resistance, and durability. The types of reinforced concrete structure houses include frame structure, frame shear wall structure, shear wall structure, simplified structure, frame tube structure, and tube in tube structure. 4. Steel structure building: The main load-bearing components of this type of building are all made of steel, which has high construction costs and is often used in multi-story public buildings or buildings with large spans. [1] （4） The classification of construction methods by building construction method refers to the methods used in building construction. Cast-in-place masonry building: The main load-bearing components of this type of building are all cast and built at the construction site. Prefabricated and prefabricated building: the main load-bearing components of such buildings are prefabricated components made in the processing plant and assembled at the construction site. Partial cast-in-place and cast-in-place masonry, partial prefabricated building: some components (such as walls) of such buildings are poured or built on the construction site, and some components (such as floors and stairs) are prefabricated components made in the processing plant. [1] （5） Classification by building durability years Classification Table by Building Durability Years: Durability Year Level/Durability Year/Scope of Application Level 1/Over 100 Years/Important Buildings and Tall Buildings Level 2/50-100 Years/General Buildings Level 3/25-50 Years/Minor Buildings Level 4/Below 15 Years/Temporary Buildings

Classification by nature of use

Residential buildings: refer to buildings designed for families or individuals to reside for a long period of time, and can be divided into residential and collective dormitories (residential buildings are divided into ordinary residential, high-end apartments, and villas; collective dormitories are divided into single employee dormitories and student dormitories). Public buildings refer to non productive buildings used by people for shopping, office, learning, medical treatment, travel, sports, etc., such as office buildings, shops, hotels, cinemas, gyms, exhibition halls, hospitals, etc. Industrial buildings: refer to buildings used for industrial production or directly serving industrial production, such as factories, warehouses, etc. Agricultural buildings: refer to buildings used for agricultural production or directly serving agricultural production, such as silos, breeding farms, etc. [1] （2） The number of floors of a house classified by floor number or total height refers to the natural number of floors of the house, generally calculated based on an indoor floor level of ± 0 or above; For a semi basement with daylight windows above the outdoor floor level, if the indoor floor height is above 2.20m (excluding 2.20m), the natural number of floors shall be calculated. False floors, attached floors (mezzanine), insertions, attics, decorative towers, as well as stairwells and water tank rooms protruding from the roof, do not count the number of floors. The total number of floors in a house is the sum of the number of floors above ground and underground. Residential buildings are divided into low-rise residential buildings (1-3 floors), multi-story residential buildings (4-6 floors), medium to high-rise residential buildings (7-9 floors), and high-rise residential buildings (10 floors and above) based on the number of floors. Public buildings and comprehensive buildings with a total height exceeding 24m are high-rise buildings, but do not include single story buildings with a total height exceeding 24m. A building with a total height exceeding OOm, whether it is a residential or public building, or a comprehensive building, is called a super high-rise building [1] （3） According to the classification of building structure, building structure refers to the system composed of load-bearing components (foundations, walls, columns, beams, floors, roof trusses, etc.) in a building.
