C16 Trapezoidal Roll Forming Machine with 23 Rows Forming Stations and Double Linear-Guide Hydraulic Cutting for 0.3-0.6mm Trapezoidal Roof Panel Production

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

The YX12‑103‑1030, also known as the C16 roll forming production line, is a well‑engineered trapezoidal roof panel manufacturing machine purpose‑built for producing wide‑coverage metal roof sheets. It completes the full production workflow, including decoiling, guiding and feeding, continuous roll forming, fixed‑length cutting, and finished panel output.

The C16 model is widely favored by metal‑working factories for its wide effective panel width, stable forming performance, and excellent cost‑performance, making it a practical investment for building‑material producers, steel‑structure contractors, and roofing component manufacturers.

Developed and assembled by Dongguang Hengfu Roll Forming Machine Co., Ltd., this machine adopts 23 forming stations to achieve smooth, gradual sheet shaping. It is optimized for processing popular wide‑size color‑coated coils. Balancing reliable performance, easy operation, and reasonable investment cost, the C16 line is perfectly suited for medium‑and‑large‑volume roof‑sheet production tasks.

The C16 roll former features a 350H‑steel welded wall‑plate frame with 14 mm thick carbon‑steel wall panels and a solid 70 mm main shaft. With 23 forming passes, metal sheets go through progressive multi‑stage bending. This gradual forming design effectively avoids material cracking or surface marks, delivering smooth and well‑defined panel profiles.

All forming rollers are manufactured from 45# steel and undergo rough turning, finish turning, outer‑circle grinding, electroplating, and quenching‑tempering treatment. High surface hardness greatly improves wear resistance and extends roller service life. The 1‑inch chain transmission system offers steady power transfer for daily industrial production. The whole machine weighs around 7.4 tons, offering solid anti‑vibration performance during long‑time continuous running.

Equipped with a double linear‑guide cutting mechanism driven by 4 kW power, the shearing unit runs smoothly. Using Cr12MoV cutter blades, it achieves a burr‑free cutting result and requires very little routine maintenance. The high‑precision rotary counter with linear‑slider bracket ensures stable length measuring. Finished panels keep a tight length tolerance within ±1 mm. The uniform dimension of each sheet brings convenience for later on‑site roof installation.

This C16 machine is fitted with a mature split‑type PLC touch‑screen control system. Operators can input target panel length, production quantity, and operating speed directly on the touch panel to trigger fully‑automatic cyclic production. The human‑machine interface is intuitive, lowering skill requirements for workshop staff. New operators can get familiar with daily operations after simple training. The machine works with a standard 380V 50 Hz three‑phase industrial power supply, compatible with most factory power supply conditions worldwide.

The production line accepts an incoming coil width of 1200 mm or 1250 mm color‑coated steel sheets. It processes material thickness ranging from 0.3 mm to 0.6 mm with material yield strength up to ≤350 MPa, producing finished panels with an effective working width of 1030 mm. Thanks to its wide coverage, C16 roof panels help reduce installation laps and save overall project material cost. Finished products are extensively applied in industrial plants, logistics warehouses, market buildings, livestock farms, and various civil roofing construction projects.

Every C16 production line undergoes complete component inspection, assembly check, and a full‑speed trial run before shipment. Customers can choose on‑site factory acceptance or remote online video acceptance. We offer clear technical guidance to support customers for smooth commissioning and production startup.
