Prefab House refers to the use of industrial production methods to build houses, that is, the stairs, exterior walls, balconies, air-conditioning panels, etc. of the house are all prefabricated in the factory outside the construction site, and then shipped to the construction site for "assembly", and the interior of the house will be refined at one time. Handed over after renovation. That is, the huge external walls, stairs, and balconies from the factory are "assembled" on the construction site into houses and buildings.
What are the advantages of a Prefab House?
What are the structural types of Prefab Houses?
What should we be careful about when selecting a Prefab House?
1. Safe and reliable
The Prefab House with steel as the main building material has a high capacity per volume unit, is more stable and solid than the traditional brick and brick concrete technology, has a better seismic performance, wind resistance, water density and refractory performance and also has thermal insulation and sound protection functions. Steel has good ductility and can better use the energy brought in by earthquakes, so it has good seismic performance and a high structural security t hat guarantees the safety of stay.
2. Easy construction and short construction time
All components are prefabricated in the factory and only have to be installed on site, which greatly shortens the construction cycle. A 6000-square-metre-long building can basically be installed in 40 days.
1. Structural system
The structure of the Prefab House can be divided into: steel frame system, steel frame support system, steel frame-core tube system, steel frame-module-core tube system and steel frame-shear-wall system. With the continuous development of the technology, newer steel construction systems will also appear.
2. Peripheral protection system
The outer protective system of the Prefab House can be divided into blocks, plates, cans and other types.
3. Internal system
Traditional construction has many disadvantages. For example, the traditional rough decoration method does not separate the interior system and the structural system, which makes it difficult to adapt to the modern development of the housing industry; the house technology lines are not separated and the water and power lines are buried in the support layer, which the "century residence" cannot realize." The waste of social resources is serious.
1.The costs are relatively higher than in the traditional Prefab House made of brick concrete and concrete.
2. The steel structure of the Prefab House, with its unique steel structure, walls, roofs and other materials, as well as the standardized and final internal distribution and support facilities, is difficult to adapt to the habits of people "arbitrarily handling the house".
3. Corrosion of steel: Al-galvanized steel must be used for maximum corrosion protection and the main steel structure can reach fifty years.
4. There are many requirements for new materials. The structure of steel houses is equipped with materials such as thermal insulation and heat protection, usually using new lightweight materials.
Prefab Houses produced by Qingdao Xinguangzheng Steel Structure Co., Ltd. feature attractive appearance, excellent performance, user-friendly operation, easy maintenance, and internationally advanced performance indicators, and are exported to more than 10 countries and regions.
Qingdao Xinguangzheng Steel Structure Group completed Qingdao Haier Yungu Supporting School Project on August 31, 2022.
Industrial steel building mainly refers to that the main load-bearing components are composed of steel. Including steel column, steel beam, steel structure foundation, steel roof truss (of course, the span of the plant is relatively large, and they are basically steel structure roof truss now), steel roof. Note that the wall of steel structure can also be maintained by brick wall.
What should be taken into account in the day-to-day maintenance of industrial steel buildings?
What are the arrangements for the planning of industrial steel buildings?
What should be taken into account when selecting industrial steel building?
After the installation of our industrial steel building, the owner is not allowed to change its structure privately, not to remove screws and other parts, and not to increase or reduce the partition wall. If you need to change a part, you need to negotiate with the manufacturer. It is up to the manufacturer to decide whether it can be changed. After approximately three years of use, the steel structure must be maintained with colour to give the building beauty and safety. industrial steel buildings are connected by steel construction components, so electrical devices such as wires should be insulated by cable channels in order to avoid accidents involving electric shocks.
The maintenance of industrial steel buildings is closely linked to the durability of the steel structure. That is why the industry pays enough attention to it. If you have problems with maintenance and maintenance, you should contact a professional steel construction manufacturer for help.
1. Insurance: Avoid rain water from the outside entering the metal roof of the industrial steel building. Rainwater enters the metal roof mainly through overlapping joints or knots. In order to achieve the function of the centrifuge, it is necessary to use a sealing disc at the screw connection and to make a concealed fixation. Use sealants or welds on the top of the plate. Best use a long board to remove the overlap. Close water-tight treatment for bleeding.
2. Fire protection: The metal material does not burn in the event of fire and the flame does not penetrate the metal roof plate.
3. Wind pressure resistance: industrial steel building can withstand the maximum local wind pressure and the metal roof plate is not removed by negative wind pressure. The wind resistance depends on the strength of the metal roof plate and the fixing seat and the density of the fixing seat.
Sound protection: industrial steel building prevents sound transmission from the outside to the inside or from the inside to the outside. Fill the metal sheet with sound insulation material (mostly insulated cotton) and the sound insulation effect is expressed by the sound intensity difference on both sides of the metal sheet. The sound insulation effect depends on the density and thickness of the sound insulating agent. Note that sound insulating agents have different locking effects on sounds of different frequencies.

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.
Prefab House refers to a building where parts and components produced in a factory are assembled and connected at the construction site. Steel structure prefabricated buildings refer to steel structure components produced in factories and assembled and connected at the construction site.
Different countries have different understandings and practices of the housing system, but Prefab House generally refers to the main project of the house. Different residential products are formed due to the selection of different structural materials, structural types and construction methods, and constitute a number of corresponding residential products ranging from design to The complete technology of construction. The steel structure residential building system uses the steel structure form as the basis for the classification of the building system and becomes a branch of the building system.
The material of Prefab House has good homogeneity and isotropy, which is an ideal elastic body, which is most in line with the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformations, and can well withstand dynamic loads; construction period is short ; It has a high degree of industrialization and can be used for specialized production with a high degree of mechanization; it has high processing accuracy, high efficiency, and good airtightness, so it can be used to build gas tanks, oil tanks, and transformers.
In the future, the steel structure of Prefab House should study high-strength steel to greatly increase its yield point strength; in addition, new types of steel should be rolled, such as H-shaped steel (also known as wide flange steel), T-shaped steel and profiled steel plates, etc. The needs of large-span structures and super high-rise buildings.
(1) Light weight and high strength. Due to the use of steel as the load-bearing structure and new building materials as the enclosure structure, Prefab House generally uses steel structure to build residences that weigh about one-half of the weight of reinforced concrete residences, which reduces the weight of the house and reduces the cost of basic engineering. Since the building area occupied by the vertical force-bearing member is relatively small, the use area of the house can be increased. At the same time, because the steel structure residence adopts a large bay and large depth column network, it provides residents with a large space that can be flexibly separated, which can meet the different needs of users.
(2) The degree of industrialization is high and meets the requirements of industrialization. Most of the structural components of Prefab House are made in factories, which are easy to install and suitable for mass production. This has changed the traditional way of housing construction and realized the transformation from "building houses" to "manufacturing houses". Promoted the transformation of the housing industry from extensive to intensive, and at the same time promoted the development of productivity.
Qingdao Xinguangzheng Steel Structure Co., Ltd. has worked on the production of Prefab Houses for several years. You can find the best Prefab House in this company.
A lot of work is needed to promote and improve the design specifications and construction technical standards of different types of structures, and to develop new types of lightweight insulation wall materials and the supporting issues of residential components. At the same time, it is necessary to widely publicize the advantages of the development of Residential steel building, so that more developers, designers and users can understand and understand steel structure housing.
What are the main forms of Residential steel building?
What are the structural characteristics of these Residential steel buildings?
What should I pay attention to when using Residential steel building?
Judging from the Residential steel building that has been built, the king has:
1) Thin-walled steel composite wall panel form;
2) Pure frame form;
3) Frame support form;
4) Form of steel-concrete combination;
5) Steel frame-concrete seismic wall form and so on.
The structural forms of Residential steel building have their own characteristics. Among them, the thin-walled steel composite wall panel is particularly suitable for finalized products. The Residential steel building system evolved from the wall panel structure, that is, the thin-walled steel column members are arranged at a distance of about 600mm. The vertical load-bearing structure and section steel have a support system to resist horizontal forces. The floor slab is arranged as a multi-rib support structure according to the position of the vertical section steel. Because the upper structure is a wall-like structure, the foundation is set as a strip foundation according to the force. The foundation requirements are not high.
The thin-walled steel composite wallboard residence is affected by the dense structure, and there are certain restrictions on the size of the partitions, door, door and window openings, and pick-out components.
The latter several forms of Residential steel building can meet the design requirements of multi-story residential buildings, but there is a common problem from the perspective of use, that is, the impact of the prominent beams and columns on the interior look and feel of the residence.
Compared with other buildings, Residential steel building has its particularity. Offices and workshops can use a relatively fixed column network, and the storey height is also higher. The space occupied by the beams and columns is suitable for people. The rules of the column network are conducive to the beams. Layout. On the contrary, the residence is a product with many changes. According to the requirements of the building, a regular column network is rarely arranged. The interior space of the house is relatively small and changes a lot, which is not conducive to the layout of the steel frame.
After seeing this and learning so much information about residential steel structures, I believe you must also want to order a Residential steel building. Qingdao Xinguangzheng Steel Structure Co., Ltd. can provide the best Residential steel building you need. At the same time, their after-sales service is also very considerate.

Nowadays, more and more industrial parks prefer to build workshop, warehouse, office and other buildings by steel structures. Why are steel structures so popular with the public? It is mainly due to the four excellent functions of steel structure "light, fast, good properties and economical".
1. Light: The steel structure has the characteristics of light weight and excellent stress function.
Steel has the smallest ratio of density to strength compared with concrete and wood. For example, the weight of steel roof trusses is only 30% or even 25% of the same concrete roof truss under the same load and strength conditions. The weight of the steel structure house is about 50% of the reinforced concrete house, but the usable area is about 4% higher than that of the reinforced concrete house.
2. Fast.
The steel structure is prefabricated in the factory then bolts contacted installation on site. It has the characteristics of mass production of large pieces and high-level precision of finished products, which effectively shorten the construction period and reducing the cost to give high investment returen. Compared with the construction period of reinforced concrete structure engineering, the steel structure is only 1/3 to 1/2 of the reinforced concrete structure under the same conditions .
3. Good properties: The steel structure has good properties and high reliability.
Steel has uniform of texture, isotropy, large elastic modulus, good plasticity ,good resistance and is an ideal elastic plastic body. Therefore, the steel structure will not suddenly break due to occasional overloading or partial overloading, it can adapt to the oscillating load, and the calculation model can reflect the mechanical properties of the steel well, so the analysis is accurate and reliable.
4.Economical.
The cost of steel structure is higher than concrete structure from the raw materials only, but the construction speed of steel structure is about 50% faster than concrete structure, which will save a lot of time and cost. The steel structure is more than 50% lighter than the overall weight of the concrete structure house, so that the cost of basic treatment and transportation will be reduced. Building is a systematic project includes many items, such as planning, manufacturing, transportation, installation, maintenance and management. Therefore, from the overall point of view, the steel structure is more cost saving.
