The light steel structure of commercial steel building is a structure composed of steel materials, and each component or part is connected by welding, bolts or rivets.
commercial steel building is mainly used for low-rise or multi-storey buildings: the prefabricated wall panels are transported to the construction site by special vehicles, hoisted by cranes, connected with the foundation by anchor bolts and connectors, and the wall panels are connected by screws and connectors, and then the light steel floor is installed. The light steel floor is composed of floor beams, profiled steel plates Steel wire mesh and concrete. The construction of the main structure can be completed by constructing the upper floor according to the construction method of one floor and finally installing the roof. The system is applicable to buildings with 6 floors and below. It has the advantages of high assembly rate, short construction cycle, earthquake resistance and typhoon resistance, thermal insulation, large use area in the sleeve, no exposed beams and columns, and recyclable materials.
1. The construction period is short. The construction period of commercial steel building can be shortened by more than 50%;
2. The project quality is stable. The quality of parts and components produced in commercial steel building factory is more stable, which solves many common quality problems of on-site construction technology and human errors in on-site construction, and ensures the project quality;
3. Energy saving and environmental protection, less construction pollution. commercial steel building adopts energy-saving technology, which greatly improves the performance of house thermal insulation and sound insulation, and improves the living comfort of the building. According to statistics, the prefabricated construction method can save about 50% water, 70% wood and 70% construction waste;
4. Integrated decoration, which is carried out simultaneously with architecture, structure and electromechanical design. commercial steel building completes the pre functional conditions, pipeline installation, wall decoration and component installation in place at one time, which not only ensures the decoration quality, but also avoids the repeated waste and secondary pollution of secondary decoration.
The construction quality problems of commercial steel building will continue to evolve and change with external changes and the extension of time, and quality defects will gradually manifest. For example, the welds of steel components cause cracks in the welds that did not originally have cracks due to changes in stress: delayed cracks can occur due to the activity of hydrogen in the welds after welding. In addition, if the component is subjected to long-term overload, the steel component will be bent and deformed under the arch, which will cause hidden dangers.
When faced with the relatively unfamiliar construction and construction techniques of steel structures, managers and technicians engaged in construction must be very careful and trained before they can take up their posts.

What are the main Steel building accessories?
How to remove the rust spots on the surface of Steel building accessories?
For Steel building accessories that have been used for a period of time, there are inevitably some attachments on the surface, such as rust, dirt, dust, old paint film, etc. Before painting the surface of Steel building accessories, if these attachments are not completely removed, although they can be temporarily covered after painting, they play a role of isolation, which makes the coating and the component substrate bond If the strength is severely reduced, the paint film will fall off prematurely, which will eventually reduce the corrosion resistance of the surface coating and fail to play the protective role of the coating. Therefore, before painting the surface of the component, the attachments on the surface of Steel building accessories should be thoroughly cleaned.
In order to improve the quality of rust removal and work efficiency. To improve the working conditions of construction workers, the current Steel building accessories derusting work has adopted a large number of wind-driven or electric small equipment. The main rust removal methods using equipment are:

Prefab House is a house constructed by industrialized production methods. It is a house constructed by prefabricating part or all of the components of the house in the factory and then transporting it to the construction site. The components are assembled through reliable connections.
What are the characteristics of Prefab House?
What are the actual advantages of Prefab House?
What is the significance of the appearance of Steel Structure Prefab House?
1. Prefab House is estimated to be about 30% faster than conventional construction methods.
2. The safety of the Prefab House is perfectly fine, since the finished steps, external walls etc. are transported to the construction site but also have to be covered instead of easy connection with steel concrete. Steel rods run through each floor, and the structure of the house is very strong.
3. Compared to traditional built houses, Prefab House has a higher component precision that can minimise frequent quality problems such as wall friction and leakage and can improve the general level of safety, fire resistance and durability of the house. It uses a light partition system and the owner can change the decoration as needed.
4. Prefab House is more energy-saving and environmentally friendly when used in the home, e.g. a new type of thermal insulation layer that has a better thermal insulation effect. When a household measurement is implemented and the heating has the same temperature, the room temperature of the "assembled" space is higher. The head of household may consider lowering the heating temperature, saving heating costs and, at the same time, reducing energy consumption.
1. The space layout of Prefab House is flexible.
2. The construction process of Prefab House is environmentally friendly and sustainable.
3. The structure of Prefab House has light weight and high bearing capacity.
4. Prefab House has excellent quality and superior seismic performance.
5. Prefab House can realize the industrialization and industrialization of residential construction, and the construction period is short.
6. Prefab House is very economical and applicable.
For a long time, the construction of houses is dominated by concrete structures. Concrete structure houses mainly use on-site manual wet work. There are problems such as low production efficiency, long construction period, high energy consumption, serious pollution, difficult to guarantee quality and performance, and short life cycle. Around the 1990s, the development of steel structures began. The appearance of Steel Structure Prefab House is a major contribution to our human habitation, reducing the pressure on the living environment. Over the years, housing construction data show that the amount of construction waste has accounted for nearly 40% of the total urban waste.
Qingdao Xinguangzheng Steel Structure Co., Ltd., which has been established for over ten years, focuses on the production of Prefab Houses. Here, you can find the Prefab Houses you need.
Industrial steel building is a great invention. All components are prefabricated in the factory, and the site only needs to be assembled simply, thus greatly shortening the construction period. For a building of 6000 square meters, the basic installation can be completed in only 40 days.
What should I pay attention to when using Industrial steel building?
What are the reasons why Industrial steel building is used more and more widely?
What are the steps involved in the general process of Industrial steel building installation?
1. Industrial steel building construction has strict requirements for construction measurement. When the steel structure workshop stops the structural calculation, the mechanical model is very clear, and the size change has an obvious influence on the model. Therefore, during the manufacturing and installation stages, construction measurement is a more important issue. For example, inaccurate blanking will result in deformation of components; failure to be placed in place during installation will affect the load-bearing effect of the environmental characteristics of the construction site welding of steel structure workshops.
2. The steel of Industrial steel building has the characteristics of thermal expansion and contraction, and it is sensitive to weather, temperature and other conditions during the installation process. Industrial steel building welding has its own special technical requirements. In practice, when natural conditions cannot meet the work requirements, manual measures are often taken to create conditions for construction, such as preheating of welding rods and preheating and heating of steel plates. If the size of the steel structure factory building changes greatly during the construction process, the temperature is too high or too low will affect the accuracy of the device.
3. The Industrial steel building is easy to rust and has poor fire resistance, so it needs to be painted and maintained. Paint the steel structure factory building fireproof coating on the exterior of the Industrial steel building to play the role of fire protection and heat insulation maintenance, to prevent the steel from rapidly heating up in the fire and reducing its strength, and to prevent the steel structure factory building from losing its support ability and causing the building to collapse.
The grid structure of Industrial steel building has the advantages of reasonable stress, large stiffness, light weight, single member and convenient fabrication and installation. In recent years, it has been widely used in public and industrial buildings with large span and large column network. It can be used not only for roof structure, but also for floors, walls and special structures.
