OKorder annually supplies products to European, North American and Asian markets. We provide quotations within 24 hours of receiving an inquiry and guarantee competitive prices.

 

Product Applications:

 

1. Heavy industrial plants: relatively large span and column spacing; with a heavy duty crane or large-tonnage cranes; or plants with 2 to 3 layers cranes; as well as some high-temperature workshop should adopt steel crane beams, steel components, steel roof, steel columns, etc. up to the whole structure

2. Large span structure: the greater the span of the structure, the more significant economic benefits will have by reducing the weight of the structure

3. Towering structures and high-rise buildings: the towering structure, including high-voltage transmission line towers, substation structure, radio and television emission towers and masts, etc. These structures are mainly exposed to the wind load. Besides of its light weight and easy installation, structure steel can bring upon with more economic returns by reducing the wind load through its high-strength and smaller member section.

4. Structure under dynamic loads: As steel with good dynamic performance and toughness, so it can be used directly to crane beam bearing a greater or larger span bridge crane

5. Removable and mobile structures: Structure Steel can also apply to movable Exhibition hall and prefabricated house etc by virtue of its light weight, bolt connection, easy installation and uninstallation. In case of construction machinery, it is a must to use structure steel so as to reduce the structural weight.

6. Containers and pipes: the high-pressure pipe and pipeline, gas tank and boiler are all made of steel for the sake of its high strength and leakproofness

7. Light steel structure: light steel structures and portal frame structure combined with single angle or thin-walled structural steel with the advantages of light weight, build fast and steel saving etc., in recent years has been widely used.

8. Other buildings: Transport Corridor, trestle and various pipeline support frame, as well as blast furnaces and boilers frameworks are usually made of steel structure.

All in all, according to the reality, structure steel is widely used for high, large, heavy and light construction.

Q:How to distinguish between steel structure materials and structures, steel types and specifications?
Carbon structural steelAccording to the current national standard "carbon structural steel" (GB700) regulations, numerical grade carbon steel structural yield point represented by the letters Q, yield point (N/mm2), the quality grade of symbols and symbol deoxidization method four parts according to the order.Carbon structural steels are divided into five kinds: Q195, Q215, Q235, Q255 and Q275. The greater the yield strength, the greater the carbon content, strength and hardness of the carbon structure, the lower the plasticity. Among them, Q235 in use, processing and welding performance is better, is one of the steel commonly used in steel structure.Quality grade is divided into A, B, C, D four, from A to D that quality from low to high. Different quality grades of steel require different chemical composition and mechanical properties. A no impact on regulations, only in the cold test only when the carbon, silicon and manganese content can not as delivery conditions; the B level, C level and D level were required to ensure 20 C and 0 C, 20 C Charpy V notch impact energy is not less than 27J (longitudinal), were required to provide assurance of conformity of bending test, as well as carbon, manganese, silicon, sulfur and phosphorus content of warranty. When all steels are delivered, the supplier shall provide the quality assurance of mechanical properties such as yield point, ultimate strength and elongation.
Q:Is the metal structure the same as the steel structure?
Dissimilarity。 Steel structures can only be attributed to one of the metal structures. There are other building materials, such as aluminum alloys commonly used in curtain walls, aluminum or magnesium alloys for large roofs, or copper panels.
Q:In the installation of steel structure, insulation foil should be placed in the side wall or side wall? Why?
I don't understand. Both inside and outside have wall panels and foil insulated cotton. Why do you use bare sheets, that is, aluminum foil?Some factories only have exterior wall panels, foil foil, interior moisture, cotton dustAs for downstairs said fire, I laughed, heat preservation itself is a fire retardant material, with aluminum foil does not matter
Q:Where are welded parts of steel structures to be subjected to nondestructive testing?
The appearance of the weld is smooth and beautiful, and there shall be no welding defects, such as blowhole, undercut, flowing, welding failure, incomplete sealing angle and non sealing.
Q:Is the floor of the steel structure slab cast-in-place or steel?
Steel structure is mainly made of steel material, and it is one of the main types of building structure.
Q:I want to make light steel structure. What tools do I need?
Another major content of the construction of steel structure is welding. The field welding equipment is mainly manual welding. As the labor costs are increasing day by day, in order to improve the efficiency, the gas shielded welding is becoming more and more popular at the installation site. Welding auxiliary equipment is the drying equipment of welding rod: drying machine.
Q:What is pre assembled steel structure, what is called steel structure assembly?
In general, the components or components of each plate are assembled into a new component through the welding and riveting process
Q:What is called a steel rivet?
It's going to be an antique. Aluminum or steel rivets are used for locking structures when they are used for retaining structures, not for structural purposes. As for the thin steel plate, the steel structure is not good, and at the very least, the structural professional pays little attention to rivet pulling.
Q:Why steel structures are more suitable for building tall and high-rise buildings?
In fact, more reasonable, in the future development trend driven by the mixed structure of economic rationality, and good technical performance so that it can occupy a place,
Q:Why steel buildings have the best seismic performance?
The steel structure has good ductility, energy consumption can be offset by seismic wave. Steel is basically isotropic material, tensile, compressive and shear strength is very high, but also has good ductility, especially the steel structure, with its own unique high ductility, reducing the seismic response. Steel structure can be regarded as an ideal elastic-plastic structure. It can absorb and consume seismic input energy through plastic deformation of structure, so it has higher resistance to strong earthquake. Compared with other structures, the steel structure is light in weight, which greatly reduces the effect of the earthquake. In addition to the high seismic performance, the construction cycle is short and industrialization
