Usage/Applications of steel structure

*Characters of Structure Steel

1. Steel is characterized by high strength, light weight, good rigidity, strong deformation capacity, so it is suitable for construction of large-span, super high and super-heavy buildings particularly;

2. It with good homogeneous and isotropic, is an ideal elastomer which perfectly fits the application of general engineering;

3. The material has good ductility and toughness, so it can have large deformation and it can well withstand dynamic loads;

4. Steel structure’s construction period is short;

5. Steel structure has high degree of industrialization and can realize-specialized production with high level of mechanization.

*Steel structure application

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.

 light steel structure for prefab house

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:What does "pre assembled" of steel structure mean?
Structure of steel (pre-assembly)The block manufacturing of large span beam column, truss, supporting steel and steel frame structures, especially in connection with high strength bolt with large steel structure, block production and supply of steel shell structure, the whole process or separate temporary assembly operations in the factory. Pre assembly is an effective measure to control the quality and ensure the installation of components in the field.
Q:What is the difference between steel structure HN and HW?
HM is called mid flange H section steel. It is H steel with a flange width ratio of 1.33-1.75. It is mainly used as steel frame column in steel structure, and is used as frame beam in the frame structure which is subjected to load, such as equipment platform.
Q:Why are the main and main beam joints of steel structures articulated?
If there is only one side of the beam, the beam bending moment into girder bending moment, for the opening section, the torsional ability is not strong, the box section can be made rigid, but the torque for an I-shaped cross section is best not to. For the main beam with both secondary beams on both sides, the bending moment at the joint of both sides of the secondary beam is small, and the bending moment on both sides can be counteracted each other, and it is feasible to make a rigid connection. But in fact, the existence of live load may cause a great difference in the bending moment between the two sides, so it is possible to produce a larger torque when the rigid joint is used.
Q:Which is better, the fire resistance of the reinforced concrete structure and the fire resistance of the steel structure?
The steel melting point, steel structure is not to the melting point, when the burning temperature reached 500 degrees, the structure will collapse, concrete has no melting point, when the temperature reached 80 degrees will appear on the surface of concrete crack, skin peeling.
Q:What is a steel structure?
The steel structure is made of steel beams, steel columns, steel trusses and so on. Each component or component is usually welded, bolted or riveted.
Q:What are the raw materials of steel structure?
In the early stage of steel structure engineering, we should pre bury and embed the steel bar, that is, the anchor bolt. The material of the anchor bolt is Q235B. There are big and small.
Q:The role of stiffeners in steel structures?
Because the product can overcome the wall thickness from the difference of stress caused by the uneven deformation of the products.
Q:In the installation of steel structure, insulation foil should be placed in the side wall or side wall? Why?
The reasons are as follows: first, the sound insulation property is good.Two, fire performance is stronger.Three, in order to facilitate installation.
Q:Is the metal structure the same as the steel structure?
Steel structure is one of the metal structures. Steel structures refer to ferrous or carbon steel structures. The metal structure will be: non-ferrous metal structure (stainless steel), aluminum alloy structure and so on.
Q:What can be painted on the surface of steel structure to prevent rust and corrosion?
Steel structure workshop: epoxy anticorrosive primer primer, intermediate paint epoxy micaceous iron oxide intermediate coating, fluorocarbon paint is above several matching scheme is one of the most common facilities, according to the different environment different anti-corrosion paint such as high-rise building steel structure, tower steel structure and so on, if not anticorrosive paint generally used in corrosion environment for epoxy zinc yellow / iron red primer, epoxy coal tar paint, such as in the harsh environment of the steel structure, generally used in the majority of zinc rich epoxy primer.
STLA is a leading manufactuer of steel structure.The annual steel structure production capacity is 400 thousand tons. We are obtained China steel structure manufacture enterprise super-grade qualification; Industrial and civil building engineering general contracting qualifications of Class One ; Steel structure engineering general contracting qualifications of Class One ;Construction project integrated design qualification of Class One and Overseas project contracting business qualification.
