Usage/Applications of steel structure/steel frame/steel construction

*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

 steel structure pipeline

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 detect crack of steel structure quickly and effectively
Crack detection usually adopts the method of magnetic particle inspection, of course, the ray flaw detection method can achieve the same effect, and is more effective for the deeper crack, but the cost is high. Ultrasonic theory can be done, but manual inspection at the scene, the workload is too large, basically impossible to achieve.
Q:What does a product frame refer to in a steel structure workshop?
The steel structure is mainly made of steel beams, steel columns, steel trusses and other components, and each component or component is usually welded, bolted or riveted. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
Q:Why should we add air holes to the embedded parts of the steel structure?
Another is due to concrete pouring into mold, into many gases, the vibrating rod under the action of gas accumulation in the lower part of the embedded parts take up, not go out, the formation of voids, the influence of embedded parts anchor, hole, air run, this part of the concrete filled. So, the concrete steel embedded parts should be appropriate to open some air holes.
Q:Why steel structures are more suitable for building tall and high-rise buildings?
The cross section has small area, light weight, large rigidity and large bearing capacity, but the fire resistance is poor and the cost is higher.
Q:Definition of large steel structures
As a green environmental protection product, compared with the traditional concrete structure, it has the advantages of light weight, high strength and good seismic performance.
Q:What effect does the welding slag not have on the steel structure or the reinforced concrete structure?
Check the pressure leakage test of the pipeline. Water test, if there is a leak point, because the welding slag cover, the exudation of water may not be out of the leak point, is not conducive to check the location of leakage point.
Q:What is meant by a steel structure? What's the explanation for the trouble?
The term "limb" in a steel structure is most commonly used in latticed columns, in which the section, section, or plate is commonly referred to as the "limb". Like the limbs of a man, at the periphery.
Q:What kind of steel is used in steel structure?
In general, Q235 is the most commonly used plant, followed by Q345., Q490 and other high strength steel, but not commonly used.I do steel structure design, often use Q235, and Q345.
Q:In the steel structure, those belong to the main steel structure, and those belong to the secondary steel structure
The main frame is steel is steel frame, steel structure, steel purlin is time support retaining structure.
Q:Installation quota, there are tubes, steel structures and general steel structure, how to distinguish between the two?
Installation is only water and electricity installation, that is, the general steel structure. I do not know what you said is the instructions, if it is the installation of water and electricity support, then the electrical and ventilation is a set of general steel structure (general iron component production, installation), the pipe is to use pipe stent installation.
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.
