Cutting -First Step of Steel Structure Fabrication Procedure

Structural steel fabrication process step 1: Cutting:

Cut steel plate into pieces and connections by flame cutting machines (CNC, Semi-automatic flame cutting machines). Long strips will be used as web and flange plate, connections will be used as connected, reinforced or stiffening plate.


Assembly-Second Step of Steel Structure Fabrication Procedure

Structural steel fabrication process step 2:  Assembly: 

Combine web and flange plate together through H-beams assembly machine, make tack welding. Keep the web plate in the middle line, do not be off the center line.


Automatic Submerged Arc Welding-Third Step of Steel Structure Fabrication Procedure

Structural steel fabrication process step 3: Gantry automatic submerged arc welding: 

Make welding by gantry submerged arc welding machine. Make sure the welding sequence and reduce the welding deformation.


Flange Plate of Straightening-Cutting -Fourth Step of Steel Structure Fabrication Procedure

Steel structure fabrication procedure step 4: Flange plate of straightening: Start straightening on welding-finished H steel beams by straightening machine. 


Connections Process-Fifth Step of Steel Structure Fabrication Procedure

Steel structure manufacturing process step 5: Connections process: Make holes on connected pieces by drilling machines. Make sure the hole size and precision.


Welding-Sixth Step of Steel Structure Fabrication Procedure

Structural steel fabrication process step 6: Welding: Make welding with CO2. Make sure the weld quality without welding flaw.


Shot Blasting and Descaling-Seventh Step of Steel Structure Fabrication Procedure

Steel structure fabrication procedure step 7: Shot blasting: Make shot blasting on steel profiles. Make sure the blasting grade and quality.


Spray Paint Processing-Eighth Step of Steel Structure Fabrication Procedure

Steel structure fabrication procedure step 8: Spray painting:Painting or other anti-corrosion surface treatment.


Packaging of Main Steel Structure Framing

Step 9: Steel Structure Packaging: Pack steel structure profiles on steel pallet, which will be easy for loading, transportation and unloading jobs.
