1030 mm Effective Width Trapezoidal Roll Forming Machine with 23 Rows Forming Stations for 0.3–0.6 mm Color Coated Steel Roof Panels

The YX12-103-1030, also known as the C16 roll forming production line, is a wide-coverage trapezoidal roof panel machine engineered for higher material utilization and efficient on-site installation. It is an ideal choice for building material manufacturers, steel structure contractors, and roofing component suppliers who want to produce large-format color steel roof panels with stable quality and lower installation consumption.

Developed by Dongguang Hengfu Roll Forming Machine Co., Ltd., this line integrates decoiling, guiding and feeding, continuous roll forming, fixed-length cutting, and finished panel output into one automatic process. With 23 forming passes, a wide effective width of 1030 mm, and a reliable industrial structure, the C16 model is especially suitable for medium- and large-volume roof sheet production.

The C16 produces roof panels with an effective forming width of 1030 mm, helping reduce the number of overlapping seams in roofing projects. Compared with narrower panel models, it lowers installation consumption and improves overall roofing efficiency. This makes the YX12-103-1030 particularly suitable for industrial plants, logistics warehouses, commercial buildings, and large-area roofing projects.

Equipped with 23 forming stations, the machine bends the metal sheet gradually through multiple stages. This progressive forming process reduces stress concentration, minimizes the risk of material cracking or surface marks, and ensures smooth, clean, and well-defined trapezoidal profiles. The result is better-looking finished panels and higher on-site installation quality.

The C16 adopts a 350H steel welded wall-type frame with 14 mm thick carbon steel wall plates and a solid 70 mm main shaft. The whole machine weighs about 7.4 tons, providing strong rigidity and excellent vibration resistance during long-time continuous production.

All forming rollers are made of 45# steel and undergo rough turning, finish turning, outer-circle grinding, electroplating, and quenching-tempering treatment. High surface hardness and good wear resistance help extend roller service life. The 1-inch chain transmission system delivers stable power for daily industrial operation.

The shearing unit uses a double linear-guide cutting mechanism with 4 kW driving power and Cr12MoV cutter blades. It produces clean, burr-free cuts and requires little routine maintenance. The high-precision rotary counting device with linear slider support ensures stable length measurement, keeping finished panel length tolerance within ±1 mm.

This production line is compatible with 1200 mm and 1250 mm incoming coil widths, and processes color-coated steel sheets from 0.3 mm to 0.6 mm with yield strength up to ≤350 MPa. Its wide material adaptability helps customers handle common market coil specifications and organize production more flexibly.

The C16 is equipped with a mature split-type PLC touch screen control system. Operators can easily set panel length, production quantity, and running speed through the intuitive interface, then start fully automatic cyclic production. The simple operation logic lowers technical requirements for workshop workers, and short training is enough for daily operation. The machine works with a standard 380V 50 Hz three-phase industrial power supply.
