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:
(1) Angle grinder: This small pneumatic equipment is mainly used to clean flat areas. It can use sandpaper, grinding wheels and wire brushes as needed.
(2) Needle Bundle Derusting Machine: This kind of small pneumatic equipment is generally equipped with 30-40 needle bundles, which can be adjusted with different working surfaces, which are mainly suitable for curved, narrow, uneven and cracked places.
(3) Single-head cold air gun: This small pneumatic equipment is also called zinc knocking. It uses the impact of the knocking head to remove rust. The diameter of the shovel head is generally 25-40mm, and it can impact 1000 to 6000 times per minute. Suitable for relatively narrow places.
1. Two-hole connection accessories
One of the main accessories of Steel building accessories is the double-hole connection accessory, which is mainly used to connect with the corners. The corners on both sides of the right-angle connection can reduce the pressure on the alloy. At the same time, the recesses of the building materials can be based on the aluminum alloy frame.
2. Single hole connector
Steel building accessories also has an important accessory, the single-hole connector, which has a completely different function from the double-pipe connector. It is mainly used for the affinity connection between the aluminum alloy frame and the ground in the ground installation. Therefore, the single-hole connector has The role of anchor bolts.
The Steel building accessories have been widely used in daily life and industrial production. Qingdao Xinguangzheng Steel Structure Co., Ltd. can provide the best Steel building accessories for their customers.

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.

Agricultural steel building is a construction of steel materials and is one of the main types of construction. The structure consists mainly of steel bearings, steel columns, steel works and other components made of profile steel and steel plates and uses silanisation, pure manganese phosphation, washing and drying, galvanising and other rust and rust protection methods.
What is agricultural steel building?
What are the characteristics of people who opt for agricultural steel building?
What are the benefits of people opting for agricultural steel building?
The agricultural steel building is characterized by high strength, low weight, good overall stiffness and high deformation resistance. It is therefore particularly suitable for the construction of large-scale and ultra-high agricultural buildings; The material has a good homogeneity and isotrope, which is ideal for elasticity. The structure most closely corresponds to the basic assumptions of general technical mechanics; the material has good plasticity and toughness, can exhibit large deformations and can withstand dynamic loads well; construction time is short; the agricultural steel industry has a high degree of industrialisation and can be specialised in agricultural production.
1. agricultural steel building has good sealing performance
Since the welding design can be completely sealed, it can be air and water-tight to high pressure containers, large oil reservoirs, pressure pipes, etc. to be processed.
2. agricultural steel building is heat resistant and non-fire resistant
If the temperature is below 150oC, the properties of the steel change slightly. The steel structure is therefore suitable for hot workshops, but if the surface is exposed to heat radiation of approximately 150, it should be protected by a thermal insulation plate. If the temperature is between 300-C and 400-C, the strength and elasticity module of the steel material decreases significantly, and if the temperature is approximately 600-oC, the strength of the steel material is zero. In buildings with special fire protection requirements, the steel structure must be protected by refractory materials to improve fire resistance.
3. agricultural steel building has poor corrosion resistance
Especially in the vicinity of moist and corrosive media, it rust easily. In general, steel structures must be rusted, galvanized or painted and regularly maintained. Specific measures such as zinc-blockanode protection are required for offshore platform construction in seawater to protect corrosion.
4.The demolition of agricultural steelworks is not subject to any building protection and the steel can be recycled and reused.
The grid structure of the agricultural steel building has an adequate load, a high stiffness, a low weight, individual rods and a comfortable production and installation. In recent years, it has often been used in public and industrial buildings with large stretches and large columns. In the construction of agricultural steel buildings there are stainless steel sandwich plates, profile plates, lighting materials and other roof materials. It can be used not only for roof constructions, but also for floors, walls and special constructions.
Agricultural steel production plays an essential role in the current industrial production process. Qingdao Xinguangzheng Steel Structure Co., Ltd. has undertaken to offer the most suitable agricultural steel buildings at a reasonable price.
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.

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.
