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.
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.
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.
Steel structure fabrication procedure step 4: Flange plate of straightening: Start straightening on welding-finished H steel beams by straightening machine.
Steel structure manufacturing process step 5: Connections process: Make holes on connected pieces by drilling machines. Make sure the hole size and precision.
Structural steel fabrication process step 6: Welding: Make welding with CO2. Make sure the weld quality without welding flaw.
Steel structure fabrication procedure step 7: Shot blasting: Make shot blasting on steel profiles. Make sure the blasting grade and quality.
Steel structure fabrication procedure step 8: Spray painting:Painting or other anti-corrosion surface treatment.
Step 9: Steel Structure Packaging: Pack steel structure profiles on steel pallet, which will be easy for loading, transportation and unloading jobs.
