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 does "HJ-1" mean in steel structures?
In steel structure, HJ-1 is truss number 1.
Q:In the installation of steel structure, insulation foil should be placed in the side wall or side wall? Why?
This is just the general case. Basically not strictly required.
Q:What does the title of a steel structure mean?
A truss is a structure in which the bars are hinged with each other at both ends. The straight rod truss has a generally triangular unit plane or space truss structure, mainly bear axial tension or stress, which can make full use of the strength of materials, the span is large than the solid web beam to save materials, reduce the weight and increase the stiffness. In the membrane structure building, truss design is very important, or it can support the whole building.
Q:How to calculate the steel structure quota?
Depends on the classification, if there is civil construction on the set of civil steel structure quota, if there is installed on the installation of steel structure quota.
Q:What does "fixation" mean in steel structures?
In general, the rigid connections of steel structural members can be completed by welding, riveting and high-strength bolts.
Q:What are the budgets for fire-resistant coatings for steel structures?
Fire resistance grade 2.5 hours, paint should be painted to 3mm. General again brush up 1.3mm thick and material price in Xi'an area with artificial material does not contain measures fee at 55 yuan / square meters of brush, but not regular professional fire, professional fire can meet the design requirements with the price will be twice as expensive as about 100 yuan.
Q:Measures to prevent rust in welded seam of steel structure
Containing 95% pure zinc, can be used for cold galvanizing, rust prevention, permeability, metal surface protection, zinc film after spraying, can effectively prevent rust and prevent corrosion spread. The main steel structures, bridges, buildings, electrical towers, tunnel facilities, containers, reinforcing steel bars, communication launchers, signs, ships, steel plates, equipment, etc., can be galvanized paint, the effect is remarkable
Q:What does steel structure HW stand for?
H is divided into hot-rolled H steel and welded H steel (H) two, hot-rolled H steel is divided into wide flange, H steel (HW), flange H (HM) and narrow flange H (HN) three.
Q:Does the column of steel structure do the ground beam or do it directly?
When the foundation is deep, the foundation top extends a thick short column upward, the pre buried bolt in short columns. This method should be on the design chart. No, there's a column in the concrete".
Q:How much is one square meter for steel structure paint?
Different paint, brush mode, operation height have an impact on the cost, the specific circumstances of the specific treatment.
