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 steel structure steel plate?
When the length of the material is controlled from 3 to 6m, the problem that the vertical transportation can not be suspended between the secondary beams can be avoided. When the floor slab is hoisted, a special soft sling is used. Check the soft sling for tearing and cutting when lifting. When the support plate is used on the steel beam, the probe shall be prevented. When laying, the operator shall wear a seat belt and ensure that the edges are secured to the perimeter safety rope.
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 does "CHS44*12" mean in steel structures?
CHS44*12 in steel structure:CHS is a round tube;44*12 specifications are: outer diameter and wall thickness.
Q:What does steel structure "Zhongshan wall post" mean?
The gable column is the column with both ends of the beam. The main function is to support and fix the gable plate, and it also plays a certain role in wind resistance.
Q:What do we call a steel rivet in the hippocampus? What's the difference between them?
The pull nail of the hippocampus is a kind of metal link with unique structure and high riveting strength. It belongs to new fastening parts. The utility model has good filling hole performance, good air tightness and high riveting strength. The utility model is suitable for riveting fields with high surface requirements, high riveting strength and requirements for sealing performance.
Q:10 meters span, from 1 meters high slope, need to use the big beam? What size of steel is welded?
Ten meters span is single or double slope slope, single slope, the slope is 10%, double slope, the slope is 20%, but such small span steel, direct line, speed, although the steel key, but processing simple labor costs.
Q:What does "BH beam" mean in steel structure?
The ratio of the area of a longitudinal force (tension or pressure) to the effective area of a member (the axial compression member is a full cross section). The reinforcement ratio and the reinforcement ratio of the compression bar are calculated respectively. Formula: P =A (s) /bh (0). Here is the angle brackets below.
Q:How can the welds in the steel structure be considered qualified?
The weld quality is divided into 3 grades, such as one or two, three, of which the quality grade of the first grade welds is the highest, and so on:Quality requirements for primary welds shall not include defects such as weld, root contraction, undercut and poor joint.There are no defects such as surface porosity, slag inclusion, cracks and arcing defects in the first and two grade welds.The three grade welds can only meet the quality standards of the above two grades with relatively low appearance.
Q:Housing cost of civil steel structure
If you stay. The structure can be made of steel structure, but the wall must be made of brick, cement and other exterior wall insulation materials.Steel structural frames must be of type H steel. As far as the price is concerned. Hard to say. All have to budget according to specifications and drawings. But I think it's better to be an ordinary house. There's no need for that mess.
Q:Steel structure workshop column and top beam how to use materials?
When the load is relatively small, steel section is preferred, such as H steel. When the load is large, the welded I-beam can be selected;
