Product Description:

Steel Structure Building

1.the connection method of steel structure:

   welding connection or bolt connection

2.Steel structure design common norms are as follows:

  • "Steel Design Code" (GB50017-2003)

  • "Cold-formed steel structure technical specifications" (GB50018-2002)

  • "Construction Quality Acceptance of Steel" (GB50205-2001)

  • "Technical Specification for welded steel structure" (JGJ81-2002, J218-2002)

  • "Technical Specification for Steel Structures of Tall Buildings" (JGJ99-98)

3.The characteristics of steel

  • Light weight steel structure

  • Higher reliability of steel work

  • Steel anti-vibration (earthquake), impact and good

  • Steel structure for a higher degree of industrialization

  • Steel can be assembled quickly and accurately

  • Large steel interior space

  • Likely to cause sealing structure

  • Steel corrosive

  • Poor fire-resistant steel

  • Recyclable steel

  • Steel shorter duration

4.Commonly used steel grades and performance of steel

  • Carbon structural steel: Q195, Q215, Q235, Q255, Q275, Q345,etc.

  • High-strength low-alloy structural steel

  • Quality carbon structural steel and alloy structural steel

  • Special purpose steel

5.Market:

Products have been all over the country more than 20 provinces, municipalities and autonomous regions, and have been exported to Europe, North America, the Middle East, Africa, Asia and other countries and regions, the widespread use

Q:What is the price of the light steel structure?
Dry light steel structure according to the size and weight are the same, is generally calculated by weight, but generally small in terms of floor area (such as construction sites for residential building, bicycle shed), if the light steel plant, building greenhouses and other large area are calculated by weight and then converted into square area cost
Q:The meaning of UT in steel structure
Acceptance specification requirement 100% is primary flaw detection, and level two requires only 20% flaw detection, ut refers to ultrasonic testing.
Q:What is the steel structure of portal frame and frame difference
The bent frame is the two row of columns, the roof trusses above, and a board placed between the roof trusses of the two rows of columns, forming a continuous structure.
Q:Steel structure brush fire retardant coating per square meter kg?
1., thin steel structure fire retardant coating 1.2kg/mm, and then multiplied by the construction of fire retardant coating thickness can be.2. ultra thin steel structure fire retardant coating 1.6kg/mm, then multiplied by the construction thickness of fire retardant coating can be.3. thick steel structure fire retardant coating 1.0kg/mm, then multiplied by the construction thickness of fire retardant coating can be.In the same project, the coating thickness of different refractory grades is different, and the thickness is determined according to the inspection report of fireproof coating factory.When you choose to buy, it is necessary to determine the fire limit of your construction, attention to choose fire-resistant steel structure fire-resistant coating.
Q:What is the roof of a steel structure?
Now, the vast majority of industrial plants are 5% of the slope, that is, at 1:20, there are a few of the 1:15 slope, depending on the construction requirements. If you want to design the steel structure without knowing how to take it, there must be no problem at 1:20.
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:Name of steel structure awning
With high strength aluminum alloy material, the joint of column and ceiling is strengthened with galvanized steel structure, so it is more secure and firm. The surface of aluminum alloy is treated by powder electrostatic spraying, and the oxidation resistance is more than 30 years.
Q:How to calculate the allowable slenderness ratio of steel structures under compression?
The slenderness ratio of the structure is I = l/i, and the radius is gyration radius.The buckling stress in the axial compression members of steel structures is only related to slenderness ratio.
Q:Why steel buildings have the best seismic performance?
1, under the same size, the steel structure has a lighter weight, and the seismic energy received in the earthquake is smaller;2, steel structure has very good ductility, each member of the moment deformation is easy to coordinate;
Q:How much is one square meter for steel structure paint?
So, the actual workload is actually derusting and corrosion protection: 45 yuan / square. That's the regular price.
