Welded Cross-section Steel Crossing Column Structural Steel Fabricators
How to fabricate cross-section steel crossing column
Welded Cross-section Steel Crossing Column Structural Steel Fabricators. The H-shaped steel production automatic assembly line is first processed into H-shaped steel, then processed into T-shaped steel, and finally assembled into ten columns.This cross-shaped steel column is used as a profile steel for steel reinforced concrete columns. After the steel plate is cut by a multi-head cutting machine, the web and the flange plate are assembled, and then welded by automatic boat-shaped position, then corrected, cut and assembled into a cross column, and the cross weld in the middle of the cross-shaped steel column is protected by CO2 gas. Soldering and welding.
Process flow:
Stakeout cutting → production of H-shaped steel → production of T-shaped steel → cross column assembly → welding of cross column → cross column correction → assembly of the zero plate on the cross column.
Our company can process all kinds of cross-beam/column shaped parts according to the drawings. Process: automatic submerged arc welding/CO2 gas shielded welding, subsequent processing content: perforated/reinforced plate/rust removal/paint, etc., main weld grade : Level 1, Level 2, Level 3, providing a flaw detection report issued by a third party.
Fabrication capacity:
We have three steel structure production lines, equipped the flame cutting machine, H-Section steel assembly machine, gantry welding machine and shot-blasting machine, paint spray booth. We also put apart the space for the fabrication of heavy-duty and large structure steel components in our workshop.
