Process

Hot-rolled steel coil

↓

Uncoiler → Leveler → Shear welder → Accumulator (Loop storage)

↓

├── Upper flange forming

├── Web forming → Welding fixture (three strips converge) → High-frequency welding

└── Bottom flange forming

↓

Cooling unit → Straightening device → Pull-out stand → Cut-to-length flying shear → Run-out table
