A roll forming production line designed to efficiently produce high-quality color steel roofing panels. It combines a welded 400H main frame, precision rollers and shafts, PLC computer control and auxiliary devices (leveling, feeding, straightening, auto receiving) for continuous, stable production.
It is compatible with a variety of sheet materials including plain steel, color-coated steel, GI (galvanized iron) and PPGI (pre-painted galvanized iron).
Typical production speed is in the 10–20 m/min range for most roofing profiles. Under optimal conditions and specific configurations the line can reach up to about 25 m/min.
Standard configurations provide around 20 rolling steps for accurate shaping. Some detailed configurations or models use up to 23 rolling stations to meet particular profile requirements.
Rollers are made from 45# steel with a 0.03 mm chrome treatment for smoothness and corrosion resistance. Roller shafts are GCr15 (shaft diameter typically 80 mm). Forming dies are processed from Cr12 die steel and vacuum quenched to a hardness around HRC58–62 for long service life.
The main machine structure is fabricated from 400H welded steel. The base uses archway structure components (QT640+570 castings) and HT200 cast sliders that are annealed and CNC finished for rigidity and durable alignment.
A PLC-based computer control system is used for precise operation, easy parameter adjustment, and reliable automated control of forming, cutting and auxiliary equipment.
The standard drive configuration uses two 15 kW K-series reducers (total 30 kW) with gear box transmission and universal joint connections. Exact electrical specifications (voltage, phase, frequency) should be confirmed with the supplier for your region.
Commonly included or available accessories are decoiler, leveling and feeding device (steel plate welded platform with 7-roller leveling), straightening device, universal straightening table, hydraulic or flying shear, and an automatic pneumatic up/down receiving table. Solar strut channel tooling and other custom attachments can be supplied.
Supported panel profiles and material thickness ranges depend on the tooling and configuration. Please provide the specific roof profile and material thickness you require so the supplier can confirm compatibility and tooling requirements.
High precision is achieved through the PLC control, multi-stage rolling (20–23 stations) and hardened, chrome-treated rollers/dies (HRC58–62). The combined roller structure reduces forming resistance and wear, resulting in consistent dimensional accuracy and long tool life.
Regular maintenance includes lubrication of bearings and chains, inspection of roller/shaft wear, checking alignment and tightening bolts. Chrome-treated rollers and hardened dies extend service intervals. Spare parts and wearing parts (rollers, shafts, shear blades) are generally available from the supplier—confirm stock and lead times when ordering.
Most suppliers offer on-site installation, commissioning and operator training as part of the package or as an optional service. Confirm scope, duration and any travel/visa costs with the supplier before shipment.
The machine incorporates guided feeding/positioning wheels and robust feeding platforms to protect material and operators. It is recommended to equip the line with guarding, emergency stop buttons, proper electrical protection and to follow local safety regulations. The supplier can advise on additional guarding and safety options.
Yes, the machine is customizable (different profiles, station counts, auxiliary units). Lead time varies with customization level, current production schedules and spare-part availability—contact the supplier with your exact requirements for a lead time and quote.
