The beam-column joints of Prefab House are mainly connected by bolt welding. However, bolted joints are recommended for fabricated steel structures. The advantage of bolted connection (weld-free connection) is that the installation speed is fast and the construction quality is easier to control.
1. The construction period is short. Generally, the first floor of Prefab House can be built in three or four days, and it only takes one or two days. Steel structure residential systems are mostly manufactured in factories and installed on-site. The amount of on-site work is greatly reduced. Therefore, the construction period can be greatly shortened, and the noise and dust generated during the construction, as well as the consumption of on-site resources and various on-site expenses are correspondingly reduced. Compared with reinforced concrete structures, the construction period can generally be shortened by one-half, the investment benefits can be brought into play in advance, capital turnover can be accelerated, and construction costs can be reduced by 3%-5%.
2. Good seismic performance. Because the steel of Prefab House is an elastically deformable material, it can greatly improve the safety and reliability of the house. The steel structure has high strength, good ductility and light weight, which can greatly improve the mechanical performance of the structure, especially the seismic performance. Judging from the situation after the earthquake at home and abroad, the number of collapsed steel structure residential buildings is very small.
In line with the development direction of building energy efficiency. Prefab House uses steel as the frame and thermal insulation wallboard as the enclosure structure, which can replace clay bricks, reduce the amount of cement, sand, stone, and lime, and reduce the damage to non-renewable resources. On-site wet construction is reduced, and the construction environment is better. At the same time, steel can be recycled and reused, and the environmental pollution during construction and dismantling is small, and its energy saving index can reach more than 50%, which belongs to the green building system.
The application of steel structure in Prefab House has opened up a new application market for my country's steel industry. It can also drive the research and application of related new building materials.
Steel-finished house is generally a residential building constructed with factory-made, economical steel profiles as a supporting work and new lightweight, heat-conserving, heat-insulating and high-strength wall materials as a home. The industrialisation of the steel building house refers to the use of steel construction houses as the final product. Through socialized mass production, the process of investment, development, construction, construction and customer service of steel dwellings is centralised and unified into an overall organisational form. The industrialization of the steel building house is the development trend of the steel building house.

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.
Commercial steel building is a new type of energy-saving and environmentally-friendly building system. It is known as one of the "green buildings" in the 21st century. It is an energy-saving, environmentally-friendly, and recyclable building structure.
The general sequence of commercial steel building welding is: pre welding inspection → preheating and derusting → installation and welding of base plate and arc striking plate → welding → inspection
1. Before commercial steel building welding, check the groove angle, blunt edge, gap and staggered joint, and remove the rust, oil stain and iron oxide scale in and on both sides of the groove.
2. Preheating. Before commercial steel building welding, gas welding or special baking gun shall be used to heat the groove and the base metal within 100mm on both sides evenly, and the surface thermometer shall be used to measure the temperature to prevent the temperature from meeting the requirements or local oxidation on the surface and preheating temperature.
3. Recheck the preheating temperature. If the temperature is not enough, reheat it to make it meet the requirements.
4. When assembling and welding the backing plate and arc striking plate, the surface cleanliness shall be the same as that of the groove surface, the backing plate shall be close to the base metal, and the arc striking plate shall be firmly welded with the base metal.
1. Welding: the weld bead of the first layer shall seal the connection between the base metal and the backing plate in the groove, and then weld layer by layer until the groove is filled. After each weld is welded, the welding slag and spatter must be removed, and the welding defects shall be ground away and repaired in time.
2. An interface must be welded continuously. If it is necessary to stop welding halfway, it shall be subject to thermal insulation and slow cooling treatment, and shall be heated again according to the regulations before re welding.
3. In case of rain and snow, commercial steel building shall stop welding. There shall be a wind shield and canopy around and above the welded junction of components. When the wind speed is greater than 5m / s, the welding shall be stopped. When the ambient temperature is lower than zero, preheating and post heating measures shall be taken for construction according to regulations.
4. Carbon structural steel shall be subject to weld flaw detection after the weld is cooled to ambient temperature, and low alloy structural steel shall be subject to weld flaw detection 24 hours after completion.
5. Welders and inspectors of commercial steel building shall carefully fill in the operation record form.
When purchasing commercial steel building, we should pay attention to the design of waterproof, heat-insulating and anti-corrosion of the steel structure. The design documents did not specify the steel derusting grade and paint and coating thickness, and did not adopt corresponding measures according to the different fire resistance limits of different parts. commercial steel building of thermal insulation protection measures needs to be avoided.
Commercial steel building has focused on the development and production of commercial steel buildings for several years. And it commits to provide perfect service for every customer from all over the world.

Industrial steel building has a wide range of applications and can be used in factories, warehouses, office buildings, stadiums, hangars, etc. to be used. It is suitable not only for single-storey large-space buildings, but also for the construction of multi-storey or high-rise buildings.
What are the architectural features of industrial steel building?
What is the reason why more and more people are choosing industrial steel building?
What types of construction are available for industrial steel buildings?
Insulation: Avoid heat transfer on both sides of the metal roof to ensure that the ambient air temperature is stable. The thermal protection function is realized by filling thermal protection materials (usually used glass wool and stone wool) under the metal roof plate. The heat conservation effect is expressed by the U-value and the unit is W/M2K. The thermal insulation performance is determined by the following factors: raw material, density and thickness of the thermal insulation cotton; the humidity of the thermal insulation wall, the method of connecting the metal roof plate and the underlying structure (to prevent the phenomenon of the "cold bridge"), the repeated ability of the metal coating to heat radiation.
Daylight: Improve indoor lighting during the day by means of skylights and save energy. When installing daylight panels or daylight glass at certain positions on the metal roof, the duration of the daylight should be adjusted to the metal ceiling panel and the connection between the daylight and the metal ceiling panel should be treated watertight.
Beautiful: The metal roof of the industrial steel building has a good texture and a pleasant color.
Check the heat expansion and contraction: check the contraction shift and direction of the metal roof plate. Make sure that in areas with high temperature differences the metal roof plate is not damaged by heat expansion and contraction.
Anti-avalanche: install snow barriers on the metal roof in snow-covered areas to prevent a sudden fall of snow.
Anti-ice caps: industrial steel building can prevent rain and snow from forming ice caps on the mould.
The frame of the industrial steel building is the main structure of the system frame. It is a flat structure consisting of columns and frames. All horizontal water loads and most vertical loads are transferred to the foundation via the plant frame. In industrial buildings, the industrial steel building frame has the following three most common types of construction;
1. The single-storey steel structure factory building frame is a single-storey frame formed from the stacked column of the factory building and the frames anchored to the top of the column (the column top can be called the system bent when the column top is foldable).
2. A rigid one-storey frame, a one-storey frame formed by a rigid connection of columns with an equal or gradual cross-section and frames on the top of the column.
3. Multi-layered frame, a multi-layered frame formed by joining columns and floor supports (or specialist works) and roof supports or roof supports.
Having learned so much about industrial steel building, it is also a difficult problem to select from many manufacturers the one with high quality and low price. Qingdao Xinguangzheng Steel Structure Co., Ltd. has been a Chinese pioneer in industrial steel building for several years. You can work with customers from design to completion to ensure that all technical requirements are met.
