This production line is our company developed guardrail plate and shaped steel special equipment, with a certain specification of steel strip as raw materials, through the cold forming method, the production of the required specifications of cold formed steel.

The mill is intended for manufacturing of round pipe of Φ88.9mm-Φ273mm with thickness of 3.0mm–8.0mm from cold-rolled and hot-rolled coil strip by means of unclosed tubular blank with its subsequent welding into tube, edge heating by means of solid state high-frequency welder, longitudinal seam welding in rolls of tube welding machine, cooling, further sizing or shaping and on-stream cutting of endless tube in measured lengths.

The technical flow of the production line {SteelTape}→→ Hydraulic Double-arbor un-coiler →→Strip-head Cutter and welder→→Spiral Accumulator→→Forming section (Flattening unit +Main driving unit +Forming unit +Guide unit +High frequency induction welding unit +squeeze roller) + De-burr frame→→Cooling unit →→ Sizing section →→Friction saw →→Rollout table

Used to straightening the round pipe, Main transmission adopts AC motor.

It adopts an imported PLC control system, and the entire machine is formed by welding thickened steel plates, featuring a stable and durable structure. It can realize integrated fully automatic production including automatic feeding, leveling, punching, forming, cutting, and discharging, without the need for a large number of manual supervision throughout the process. The equipment utilizes precision roll technology; the rolls are made of cemented carbide, undergo quenching and precision machining, resulting in high forming accuracy and strong wear resistance. The produced C-section steel has standard dimensions, a smooth surface without scratches, and excellent load-bearing performance, fully complying with industry standards.
