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


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?
Sandwich board (plated plastic plate 0.3/0.4 thick) 50 75 yuan /m, 5, 6 local steel prices and taxes (1+2+3+4+5+6), building area = unilateral cost you can adjust according to the actual situation of the local (as long as the labor cost, material cost adjustment) Oh, I hope useful to you
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:Why can't epoxy paint be used in outdoor steel structures?
Epoxy paint used as primer, iron red epoxy primer, epoxy zinc primer can be matched with acrylic polyurethane paint, fluorocarbon paint, etc. for outdoor weatherproof coating.
Q:What effect does the welding slag not have on the steel structure or the reinforced concrete structure?
Affect corrosion. Welding slag is porous, such as not welding slag, anti-corrosion paint can not effectively prevent oxygen and welding alloy contact, will cause rust.
Q:What is a light portal steel frame?
Light steel structure is made of steel (steel plate and shaped steel), and compared with other materials, the steel structure has the following characteristics:High strength steel strength and elastic modulus of concrete, masonry and wood to be many times higher, due to the small weight, high stiffness, steel structure for the construction of large span and super high and super heavy buildings especially suitable for.Small weight - the weight of ordinary steel roof truss only reinforced concrete roof truss 1/4~1/3, if the use of thin-walled steel roof, it is lighter. Because of its light weight, the steel structure is also convenient for transportation and lifting, and can lighten the burden of the substructure and the foundation.Uniform material - the internal structure of the steel is uniform, very close to the isotropic body, and in a certain range of stress, it belongs to the ideal elastic work, and accords with the basic assumption adopted in engineering mechanics. Therefore, the calculation method of steel structure can be accurate and reliable according to the principle of mechanics.
Q:Is cast-in-place concrete attic good or steel structure + ALC board good?!
The short cycle of cast-in-place steel structure high stability, light weight, does not destroy the original structure, anchorage hole cast-in-place the original wall hit double row hole spacing of ten cm each with adhesive implantation wall, wall depth of ten to fifteen cm, and the steel structure is not greater than the chemical anchor spacing bolt with wall of not less than thirty cm fifty cm fifteen cm deep into the root.
Q:Steel structure workshop and equipment have static electricity is how?
Remind: if you hit the steel structure was not necessarily static, static steel structure, but you have the electrostatic savings, met steel structure rapidly after being led into the earth, you have been playing the static feeling, this is the most general.
Q:Steel structure, tied with brace pipe casing and how the difference? What difference?
The basic line tied in portal structure, drawing on the acronym XG, general specification for pipe 114, is connected to each portal frame brace; acronym T, general specification for the 12 round, the role is to the whole roof purlin
Q:What is called a steel rivet?
In the 60 and 70s, high-strength bolts have not yet, welding technology is not as advanced as now, so many of the steel structure connections, by rivets, see the old movies, sometimes see.
Q:Steel structure component assembling method
Vertical mounting: according to the characteristics of components and the stable position of parts, choose the top-down or bottom-up assembly. The method is applicable to a structure with a smooth and small height or a large diameter cylinder.
