760 Standing Seam Roll Forming Machine

This 760 standing seam roll forming machine is professional cold forming equipment for manufacturing 760mm effective width interlocking standing seam metal roof panels. The finished roof sheet features high vertical standing ribs and interlocking edge structure. During on-site installation, panels can be locked together without exposed fixing screws, greatly improving roof waterproof, wind resistance and anti-leakage performance. It is widely used for large-span logistics warehouses, solar power station roof systems, modern industrial workshops, light steel villas and scenic architecture.
The machine can process 0.4–0.8mm aluminum magnesium manganese alloy strips, color coated steel coils and hot-dip galvanized steel strips. It realizes automatic uncoiling, multi-pass continuous roll forming and fixed-length hydraulic cutting in one integrated production line without secondary processing.

The whole machine frame adopts heavy extra-thick channel steel integral welding structure, which goes through high-temperature stress relief annealing after welding to eliminate internal welding stress. The rigid frame guarantees stable and vibration-free long-time high-speed forming, maintaining consistent forming precision for every finished panel.
All forming rollers are precision turned solid 45# carbon steel with multi-layer surface quenched hard chrome plating, featuring high hardness, wear resistance and rust-proof performance, scratch-free forming for soft aluminum alloy and thin color steel sheets. A total of 20–26 groups of progressive bending roller stations are arranged in order, completing complex standing rib and interlocking edge multi-angle bending in one feeding stroke. The spring-back value after forming is strictly controlled within standard range, ensuring neat panel edges and tight interlock effect. Standing rib height and lock seam shape can be fine-tuned according to customers’ local construction drawings.

Variable frequency synchronous chain transmission system is equipped for stable low-speed operation, forming speed adjustable from 6 m/min to 20 m/min steplessly to match different thin metal raw materials. A heavy-duty bilateral mechanical deviation correction device is installed at the feeding inlet to guide steel strips to run along the central track and avoid offset raw material waste.
At the tail, an integral vertical heavy hydraulic cutting unit is configured with thickened special wear-resistant alloy cutting blades suitable for aluminum, galvanized and color steel sheets. The cut ends are flat without burr, collapse or deformation, and the fixed-length tolerance of finished roof panels is controlled within ±1mm. An independent small hydraulic station provides stable cutting pressure without oil leakage during long-term circulating work.

An independent large touch screen PLC control cabinet is matched with the machine, pre-storing multiple groups of 760 standing seam profile parameter recipes. Users can one-click switch different production specifications without repeated parameter resetting. The control system supports automatic length counting, fixed-length shutdown, real-time speed display and fault self-diagnosis functions. Only one ordinary operator can complete full-line production monitoring work, greatly lowering labor operation threshold. Overload protection and emergency stop switch are equipped to reduce production safety risks.

This 760 standing seam roll forming machine can be perfectly matched with hydraulic coil reel uncoiler to form a fully automatic continuous feeding production line. We support customized adjustment of standing rib height, effective width and raw material thickness range according to customer’s project requirements.
Each standing seam forming machine will undergo a 72-hour non-stop full-load coil endurance test before delivery. Our engineers repeatedly calibrate forming wave radian, interlocking tightness and cutting length tolerance to eliminate all hidden quality troubles before shipment. Complete spare forming rollers, cutting blades, hydraulic sealing parts and bilingual English-Chinese operation & maintenance manuals are provided as standard free accessories.
We offer a 2-year full machine comprehensive warranty covering all mechanical and electrical components. The delivery cycle is 50–60 days after receiving customer’s advance deposit. Custom three-phase industrial voltage (380V/415V/220V) is supported to adapt to power supply standards of different countries. Professional remote video installation, commissioning and operation guidance service is available for all overseas buyers.
