Heavy Duty Automatic Non Scratch Trapezoidal Roll Forming Machine for Trapezoidal Roof Sheet Machine Production

Manufactured by Dongguang Hengfu Roll Forming Machine Co., Ltd.

The YX21‑164‑820 roll forming production line is a high‑speed, heavy‑duty automatic solution for manufacturing premium trapezoidal metal roof panels. Engineered by Dongguang Hengfu Roll Forming Machine Co., Ltd., it realizes a complete automatic production process from coil decoiling, material guiding and roll forming to fixed‑length shearing and finished panel output. Designed for real industrial mass production, this line delivers stable profile quality, high output efficiency and reliable long‑term operation, making it an excellent production asset for building material factories, steel structure manufacturers and metal processing enterprises.

The machine adopts a heavy‑duty 350H steel welded wall‑type frame with thick carbon steel wall plates, solid main shaft and 18 forming stations, ensuring extremely high overall rigidity. Even under long‑hour heavy‑load continuous operation, the frame remains stable and resistant to deformation, helping maintain consistent forming accuracy over time.

All forming rollers are finished through precision machining, tempering and electroplating treatment, providing high hardness and excellent wear resistance. Compared with traditional chain drive, the gear transmission system delivers smoother power transfer, reduces high‑speed vibration and ensures more uniform panel forming results.

Both the main forming unit and shearing unit are equipped with high‑power servo motors, enabling stable and adjustable high‑speed operation. The double linear‑guide servo electric shear runs smoothly and produces clean, burr‑free cuts without secondary trimming. This improves finished product quality while lowering maintenance requirements.

A high‑precision length measuring device ensures excellent dimensional repeatability, so each finished roof panel has a consistent profile and accurate length. Neat and precise panel dimensions support tighter overlap during installation and reduce the risk of roof leakage. The warning alarm light provides clear production status feedback and improves on‑site workshop management.

The production line is equipped with a proven split‑type PLC touch screen control system. Operators can easily set panel length, production quantity and running speed through the intuitive interface, enabling fully automatic cyclic production. The simple operation logic reduces the skill requirement for workers, and short training is enough for daily operation.

Complete safety devices such as the foot‑pedal emergency stop switch further protect operators during production. Designed for 380V 50Hz three‑phase industrial power supply, the machine can adapt to most factory power environments worldwide.

The YX21‑164‑820 is suitable for processing standard color‑coated steel sheets within a reasonable thickness range. It produces high‑quality trapezoidal roof panels with high structural strength, neat surface and good weather resistance. The finished panels are widely used in steel structure workshops, large warehouses, commercial buildings, agricultural sheds and various construction roofing projects.
