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.
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.

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.
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.
The advantages of industrial steel building are high seismic performance, good fire resistance, short construction period, and durability. Compared with traditional factory buildings, industrial steel building has improved a lot, so it is strongly welcomed by the market.

What are the advantages of industrial steel building construction?
1. From the height:
The height of the drip level of a single-storey factory building is very important. Some factory buildings are 4-5 meters high, some are 6-7 meters, and some can be as high as 11-12 meters or higher. Generally, the taller the factory building, the more difficult it will be to build, and the more expensive the material costs will be.
2. From the external building structure:
Simple iron sheet: It is the simplest, a factory built with iron sheet relatively freely.
Steel structure workshop: The steel structure workshop is divided into steel structure or ordinary steel structure. Color steel structure is more than ordinary
much better.
Concrete structure: The wall is built with bricks and the roof is sealed with concrete. This structure has better safety and heat insulation than the previous two.
3. From the internal structure:
It is divided into those with corbels and those without corbels. Only the workshops with corbels can install cranes (also called cranes). This is an important part of industrial production. If there are machinery and equipment to install cranes, just Must have corbels to use.
industrial steel building has the characteristics of forming a large space for use, easily meeting the requirements of the production process, and convenient internal transportation organization, which is conducive to the placement of heavier production equipment and products, and can realize the industrialization of the production of plant building components and the mechanization of on-site construction. Therefore, industrial steel building has been widely used in industrial buildings such as metallurgy, machinery manufacturing, motor manufacturing, chemical and textile industries. Common structural forms of reinforced concrete single-story factory buildings include bent frame structure and rigid frame structure.
1. industrial steel building has good structural performance, light weight, high strength, and good seismic performance.
2. The steel used in industrial steel building is recyclable, which is more energy-efficient and environmentally friendly than masonry and concrete.
3. The industrial steel building is processed by the factory, so the quality of the industrial steel building is guaranteed.
4. industrial steel building materials have light weight and low base cost.
5. The on-site construction period of industrial steel building is short. There is basically no wet work on site, and no dust, sewage and other pollution will be generated.
6. The cross-section of structural components is small, the pillars are very thin, the walls are very thin, and the building area is large.
Qingdao Xinguangzheng Steel Structure Co., Ltd. has been committed to providing customers with reliable industrial steel buildings and perfect after-sales service so that customers can invest easily, use them with confidence, and have no worries.
Steel structure workshop is composed of frame, beam, wall and weighing column, etc. In the design of single-layer steel structure workshop, the first thing to ensure that the structure of the workshop does not affect the use of the second in the design time to calculate the bearing force of the beam, the selection of materials to meet the relevant standards.
Composition of single-layer steel structure workshop:
1. Transverse frame: composed of columns and the roof truss or roof beam supported by it, it is the main load-bearing system of the steel structure of single-storey workshop. It bears the dead weight of the structure, the wind and snow loads and the vertical and horizontal loads of the crane, and transfers these loads to the foundation.
2. Roof structure: structural system bearing roof load, including transverse frame beam, bracket, middle roof frame, skylight frame, purlin and so on.
3. Support system: including the support of the roof part and the support between columns. On the one hand, it forms the longitudinal frame of the steel structure of the single-storey workshop with columns and crane beams to bear the longitudinal horizontal load; On the other hand, the main load-bearing system is connected by individual plane structure into the whole structure of space, so as to ensure the necessary stiffness and stability of the steel structure of the single-storey workshop.
4. Crane beam and brake beam (or brake truss) : mainly bear the vertical and horizontal load of the crane, and transfer the load to the transverse frame and longitudinal frame.
5. Wall frame: Bear the dead weight and wind load of the wall.
Single-layer steel structure plant design points:
1. In the column network arrangement of single-storey steel structure buildings, when column spacing is not equal, especially the column spacing of each longitudinal column column, the columns should be arranged on the common horizontal positioning axis to ensure the stiffness requirements of the workshop, so that the workshop can be used normally.
2. For the temperature expansion joint section length of single-storey steel structure building, it is better to set the expansion joint when the plant structure exceeds the designed value under special circumstances. This has the advantage of being separated into independent structures, making temperature changes negligible after a drop.
3. The transverse frame calculation of single-storey steel structure building. The transverse frame structure transfers the load and action of the plant structure to the foundation, which is the main load-bearing structure of the plant.
4. Calculation of longitudinal force transmission system of single-storey steel structure building, steel column, column.
