Steel structure prefabricated building is a new environmentally friendly building,it is trend of building in future.Nearly all kinds of building could be built by steel structure design system including civil building,commercial building,industrial building,agricultural building and so on,Compared with traditional concrete buildings,steel structure building is better in structure strength,anti-earthquake and space utilization.Installation is quick due to prefabriated components.Moreover,because steel id reusable,so,it is more environmentally friendly.Now,steel structure technology is a mature technology in high-rise building and super high-rise buildings.It has became mainstream in construction design.
1.Quick installation:
All steel structure parts are pre-fabricated in the factory and then shipped to the site for direct installation. Customers do not need to be welded at the site, reducing installation time.
2.Ample internal use space:
The steel structure prefabricated building has a large span, except for the pillars supporting the roof steel beams on both sides，there are no pillars inside. The forklift will not encounter obstacles during internal travel, which significantly improves the used space.
3.Building materials can be recycled:
90% of the steel structure prefabricated building materials can be recycled, which improves the reuse rate of materials.
4.Environmental-friendly
During the construction process, there is no construction waste and dust, no water is needed, water saved, and there is no noise, which will not affect the average life of surrounding residents.
| 1 | Steel structure | Q235 or Q345,column and beam ,which are generally assembled and welded with hot-rolled H section steel or steel plates. |
| 2 | Purlin | Q235 or Q345，C or Z section channel |
| 3 | Roof cladding | sandwich panel or corrugated steel sheet |
| 4 | Wall cladding | sandwich panel ,glass curtain,aluminium panel for choice |
| 5 | Sag rod | Q235,circular steel tube |
| 6 | Bracing | Q235，steel rod, L angle, or square tube. |
| 7 | Column&transverse brace | Q235，angle steel or H section steel or steel pipe |
| 8 | Knee brace | Q235，L 50*4 |
| 10 | Rainspout | PVC pipe |
| 11 | Door | Sliding Door/Rolling Door |
| 12 | Windows | Plastic Steel Window/Aluminum-alloy Window |
Step 1 Blanking
Checking specifications，quality and appearance of raw material,then cutting steel plate into sizes required by Numerical Control Cutting Machine.
Step 2 Formation
Fixing the flange plates and the web.The gap between the flange plate and the web must not exceed 1.0mm.
Step 3 Sybmerged Arc Welding
Welding the flange plates and the web. The welding seam surface must be smooth without any holes and slags.
Step 4 Correcting
There will be greater welding deformation after welding the flange plates and web together, and also deviation of the squareness. Therefore, it is necessary to correct the welded H-steel by straightener.
Step 5 Drilling
After drilling, burrs must be cleaned up without damaging the base metal. If the deviation of the hole distance is beyond the specified scope, the quality of electrode must be as same as the base metal. Drill again after polishing smooth.
Step 6 Assembling
Strictly follow the drawing to assemble and consider the pre-welding shrinkage according to the characteristics of steel components. Then,continue processing after confirming without any error.
Step 7
CO2 Gas Shielded Welding
Step 8 Shot Blasting
By shot blasting, the surface roughness will be gained, which can increase the adhesion of paint film and imporve the surface quality of paint and preservative effect.
Step 9 Straightening, Cleaning and Polishing
Step 10 Painting
Step 11 Spraying and Packaging
Step 12 Finished products storaging
Drawing and quotation will be offered within 1 day once the details are informed.Customized drawign are welcomed,it doesn’t matter even if there is no one.
