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 are the differences between steel structures and concrete structures?
The strength of the steel is high and the modulus of elasticity is high. Compared with the concrete and wood density and the ratio of yield strength is relatively low, and therefore under the same loading conditions section of steel structure is small, light weight, convenient transportation and installation, suitable for large span, height, weight bearing structure.
Q:What are the accessories in the steel structure?
The maintenance system includes: roof and wall inside and outside pressure plate (a single plate project) and thermal insulation layer, and various accessories, standard parts, gutter drainage wall and roof lighting and window part.
Q:Installation quota, there are tubes, steel structures and general steel structure, how to distinguish between the two?
Installation quota, the pipe structure is hollow, pipe, solid steel, and the two how to distinguish between the problem, that is, hollow and solid division.
Q:What does HN350*175*7*11*16 represent in steel structures?
That is a high x steel beam flange width x x web thickness, flange thickness, flange width steel beam is as high as 300, 175, 7 for the web thickness, flange thickness is 11, 16 is the last R arc.
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: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:What is the rib of steel structure?
Is in the beam web on both sides of configuration, perpendicular and beam flange and web (most so, some web and not vertical) two plates, there are unilateral configurations, but rarely, at the ends of the beam can be used in a sealed.
Q:Why steel structure does not fire?
Steel structure is the most fatal weakness is the fire resistance of steel is very poor, the internal crystal structure of steel is very sensitive to temperature, temperature rises or falls will change the performance of the steel, steel structure is typically 450 to 650 DEG C will lose the bearing capacity, big deformation, resulting in steel column and beam bending results. Due to large deformation can't continue to use.
Q:What is the steel structure XLT?
The steel structure is XLT diagonal brace.Steel structure is mainly made of steel material, and it is one of the main types of building structure.
Q:Does the column of steel structure do the ground beam or do it directly?
The embedded bolt shall be accurately laid on the foundation according to the location and size. When the foundation is deep, the foundation top extends a thick short column, the pre buried bolt in short columns, pay special attention to ensure accurate position and size of bolts.
