Product Description:

 

OKorder is offering steel structure at great prices with worldwide shipping. Our supplier is a world-class manufacturer of steel, with our products utilized the world over. 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.

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.

Q:Steel structure platform cost
Give me your drawings, the quota to be used, your construction organization plan and other relevant information to me. I'll calculate the cost for you
Q:How is the roof of the steel structure closed?
It is usually made with a plate 1 meters wide, depending on the length of the field. Press three knives, the first side is advisable 80mm, the second side takes 420mm, the third side takes 420mm, the fourth side takes 80mm, and the total length is 1 meters. The first angle is 120 degrees, and the second angles should be calculated according to the slope of the roof, that is, when the roof is mounted, the second side slope is the roof slope, and the third angles are the same as the first corner.
Q:What is the proportion of paint for large steel structures and what thinners do they have?
A variety of film-forming substances according to national standards, a total of xxx. It is the main part of the paint, determines the performance of the film. If there is no film forming material, pure paint and auxiliary material can not form paint film.
Q:How is the steel structure foundation checked and accepted?
When the foundation works in the handover, every time the acceptance of not less than one can form the installation unit space stiffness plinth foundation, and shall comply with the following provisions: the foundation of concrete strength to meet the design requirements; based around backfilling completed; and high standard basic symbol axis and datum point accurately, top surface of the foundation shall be complete; flat, two times of the surface water cut hair, bolt should be intact.
Q:Why should we add air holes to the embedded parts of the steel structure?
The embedded parts is provided with a ventilating has two uses: one is that it can be used to insert concrete vibrator vibration rod.
Q:What does the name below the steel structure of the pillars of the corner piece of iron bolt connection called ah
Another is the column base plate of steel column with embedded parts welding, some with anchor bolt, bolt connection side, while welding, some do not anchor bolts, direct welding and embedded parts.
Q:In the steel structure of steel purlin 160*60*20*2.5 is what mean
Channel steel is a strip of steel with a cross section. Section steel with groove shape.
Q:Excuse me, how to steel structure materials such as ah, how do I know purlin, bar, etc. What material is tied ah
These are commonly used in steel structure terminology or custom terminology, is the component is not material, the materials used are mostly profiles or cold bending materials, hardware manuals can not be found.
Q:In the steel structure safety margin refers to what?
The ratio of the structural stress to the design stress minus 1 is used as a positive fraction of the strength of the structure.
Q:Which is better, the steel structure or the frame structure?
Brick wall bearing, called brick concrete structureCommonly used in the 7 storey below ordinary multi-storey residentialThe utility model has the advantages of low cost and simple and fast construction.Disadvantages: not suitable for complex forms, floors, room size and other construction requirements strictly, seismic capacity weaker.
