Steel structure office building fabrication process:
1. Prepare raw materials : cut steel plate or use internation size H section steel and angle steel, round tube, round steel, square tube etc.;
2. Assembly and welding: our welders will follow the drawings to assemble the steel members and weld them together as a entire beam/column/brace and so on; (Our quality inspector will check the steel pieces after finish welding, this is the first quality check)
3. Sand blast : After finish welding and polishing, our sand blast effect can reach internation 2.5 high grade, very good for resist rust; (Secondary quality check)
4.Paint : Within 2 hours after sand blast, all the steel members should be paint. Client can choose any color and any brand of paint. (The third quality check)
5. Inspect the goods by client : After we finish a part of fabrication work, we will invite clients to check the goods before we pack the steel frame.
6.Packing and loading : If clients require us to load the goods by close containers, we will pack the steel structure members one by one on the steel skid and tie the whole steel package well. (The fourth quality check )
Technical Parameters:
1. Main Steel Structure: Use build-up steel column, welded H-beam steel
2. Purlin: C-type steel
3. Roof panel: Single steel sheet or sandwich panel
4. Wall panel: The same to roof panel
5. Tie bar: Welded-round tube
6. Brace: Round steel
7. Column brace and lateral brace: Angle steel
8. Crane: 3T-30T
9. Angle brace: Hot-rolled angle steel
10. Edge: Color plate
11. Gutter: Stainless steel
12. Down pipe: PVC Pipe
13. Door: Sandwich-panel door or Rolling door
14. Window: Aluminum alloy window or PVC window


Advantage of the building:
(1) Enough strong
it can resist 70m/s hurricane and G10 seismic intensity and protect your life and property. Furthermore, we also can design and build a stronger building according to your required.
(2) No water-seepage problem.
through the research and test by our technical team and construction team, we designed a whole reasonable and effective method of flashing plate and over-lapped of steel sheet, include(1. flashing plate on the roof, wall, bridge, eave, gutter and frame of window and door, 2. Joints between steel sheets and sky lighting belts, 3. Waterproof of nails ), with accuracy process and superior quality closure strips, we successfully reduce the leakage place from 1/1000 to 1/2500 place/sqm.
(3) High-performance heat insulation
Many sorts of material can be use as the roof panel and wall panel, which can bring the warm in winter and cold in summer for you house.
(4) Excellent Anti-corrosion and long life
shot blasting and 4 layers paint(90micron)/1 layer hot deep galvanized (80-200g/sqm) will provide our building 25-50 years life.
(5) Good air permeability and more natural lighting
natural roof turbine ventilators, bridge ventilators, Roof sky lighting belts, Wool sky lighting belts and varies of windows, they will bring us more fresh air and natural lighting.
(6) Quick installation
12 workers can assemble 1000sqm within 20 days.
(7) 100% recovery.

Q: Steel structure factory building fire prevention performance?
A: Mainly adopts fireproof coatings, foam fire retardant paint, and fire protection measures such as casing.
Q: The steel structure factory building common economic anticorrosive measures?
A, 1, hot dip galvanized, hot dip galvanized after rust removal of steel structure components in 600 degree centigrade high temperature melting zinc liquid, make the zinc layer adhered on the surface of the component, the advantage of this approach is durable life, long-term anti-corrosion, high industrialization degree, stable quality
2, coating: Coating method is not better than long-term anticorrosion method, but the fixed number of year of the fluorine carbon coating corrosion resistance can be up to 50 years, it is been used widely in indoor structure or for ease maintenance outdoor steel structure, with lower cost, but when used in outdoor it requires constant maintenance.
3, Cathodic protection, widely used in the underwater or underground structure
