For our every steel building, our engineers choose the most economical and reasonable materials according to the local wind and snow load with the building’s height and width. The used steel sizes are calculated by architectural Design Software, in accordance with China’s steel structure technical design standard.

STEEL STRUCTURE MEMBERS PRODUCTION (Fabrication) PROCESS :
1. Prepair raw materials : cut steel plate or use internation size H section steel and angle steel,round tube,round steel,square tube etc. with right sizes;
2. Assembly and welding: our welders will follow the drawings to assembe the steel members and weld them together as a entire beam/column/brace and so on.
Our welders are skilled in butt weld,fillet weld,intermittent welding etc. The welding lines are straight,orderly and nice.
Our quality inspector will check the steel pieces after finish welding,this is the first quality check.
3. Sand blast : After finish welding and polishiing,our sand blast effect can reach 2.5 high grade,very good for resist rust. 2.5 high grade could meet most countries' standard requirements.
(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.
We use hight pressure airless spraying machine for painting. Both the color and the thickness of paint are well-proportioned.
(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 )
For loading containers, there are different containers for different demands, like 20'GP, 40'HC, 40'OT.
Open top container:
Advantage:easy to load the steel; save steel pallet cost
Disadvantage:high shipping cost,aleak and few quantity to load
Closed container:
Advantage:save shipping cost,all members be packed together and reduce friction,the surface coating of steel members will be much better protected; easy unload
Disadvantage:steel pallet cost
Details Confirm in advance will let us know what you need:
| Project Details for the quotation: | |
| 1 | Size: Length*width*height _____mm*_____mm*_____mm |
| 2 | Wind load (max. Wind speed) _____kn/m2, _____km/h, _____m/s |
| 3 | Snow load (max. Snow height) _____kn/m2, _____mm |
| 4 | Thermal insulation If yes, EPS, fiberglass wool, rockwool, PU sandwich panels, Corrugated steel sheet with fiber glass wool will be suggested; If not, the Corrugated steel sheet will be ok. The cost of the latter will be much lower than that of the former. |
