820 mm Effective Forming Width Trapezoidal Roll Forming Machine with 18 Forming Stations and 0–40 m/min Production Speed for Trapezoidal Sheet Forming

If you are looking for a high-speed, stable and easy-to-operate roof panel production line, the YX21-164-820 from Dongguang Hengfu Roll Forming Machine Co., Ltd. is worth your attention. This equipment is designed for building material factories, steel structure enterprises and metal processing workshops that need efficient mass production of trapezoidal roof panels. It integrates coil decoiling, material guiding, roll forming, fixed-length shearing and finished panel output into one fully automatic process, helping customers improve output, stabilize quality and reduce operating pressure.

The YX21-164-820 adopts a heavy-duty 350H steel welded wall-type frame, thick carbon steel wall plates, solid main shaft and 18 forming stations. This structure greatly improves overall rigidity and reduces deformation risk during long-hour heavy-load operation. The stable frame helps maintain forming accuracy and product consistency over time.
All forming rollers are precision machined, tempered and electroplated, offering high hardness and excellent wear resistance. The gear transmission system provides smoother and more powerful power output than traditional chain drive, reducing vibration and ensuring more uniform panel forming quality.

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 delivers clean, burr-free cuts without secondary trimming, reducing manual work and improving finished product appearance.
A high-precision length measuring device ensures accurate and repeatable dimensions, so each finished panel has a consistent profile and precise length. Neat panel dimensions help achieve tighter overlap during installation and reduce the risk of roof leakage. The warning alarm light also helps operators monitor production status more conveniently.

The machine is equipped with a 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 lowers the technical threshold for workers and reduces training time.
Safety devices such as the foot-pedal emergency stop switch provide better protection during production. Designed for 380V 50Hz three-phase industrial power supply, the YX21-164-820 can adapt to most common factory power environments.

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