The components of the steel structure have many advantages, like small section, light weight, easy to transport and installation, suitable for large span, high height, heavy bearing structure.
Suitable for withstand impact and dynamic load, with good seismic performance.The internal structure of steel is uniform with high reliability.
Factory mechanized production of steel structure components finished products of high precision, high production efficiency, site assembly speed, short construction period.

Steel Structure Components Production
Prepare raw materials :
cut steel plate or use H section steel and angle steel,round tube,round steel,square tube etc. with right sizes;
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 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.
Sand blasting :
After finish welding and polishing,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)
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 high pressure airless spraying machine for painting. Both the color and the thickness of paint are well-proportioned.
(The third quality check)
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.
Steel Structure Building Installation
1.Foundation construction (pre-embedded anchor bolts),
Installing detailed drawing will be offered in advance.
2. Column installation
One worker commands truck crane how to move, 3 ~ 4 workers cooperate with crane to install the steel column, put column to anchor bolt location.
3.Beam installation
After completing the installation of adjacent two steel column, then main beam begin to install.
4.Installing roof & wall purlin
The roof and wall purlin will be installed after finishing column and beam. Bolting the purlin on the main structure.
5.Fixing wall and roof sheet
To fix the wall sheet on wall purlin by self-tapping screw; then fix the roof sheet.
6.Fixing the cover
To install the cover on the corner, eave, window and door opening.
7.Install windows and doors.
