Purlin Roll Forming Machine

Sinno Purlin Forming Machine - Making High-Strength Steel Framing Simple

The Sinno Purlin Forming Machine is a precision-engineered production line for producing C-, Z- and sometimes Sigma-shaped steel purlins - structural members that are key to supporting roof and wall systems. This advanced equipment integrates a hydraulic unwinder, a fully automatic forming unit, a flying shear cutting system and a PLC control system for seamless high-speed operation and minimal manual operation.

The structural backbone of modern steel buildings

Unlike roof panels or cladding panels, purlins are the invisible frames that give steel buildings their strength. The Sinno Purlin Forming Machine enables manufacturers to produce frame profiles in a variety of sizes and thicknesses to meet the needs of warehouses, workshops, agricultural buildings and prefabricated structures.

One machine, multiple profiles

Thanks to its automatic size conversion system (optional), the machine can quickly and tool-free convert between purlins of different sizes and shapes. From C-shaped to Z-shaped profiles, flange height, web width and lip angle can all be adjusted through touch screen settings, reducing downtime and increasing productivity for custom orders.

Heavy-duty construction, precise output

The machine features a sturdy welded frame, precision-machined rollers and a high-torque drive system to operate continuously under load. All rollers are CNC-finished and hard-chrome plated for increased wear resistance, ensuring precise forming and long-term durability.

Straight, strong and easy to install

The finished purlins have excellent dimensional consistency, clean cuts and smooth edges. These profiles are easy to bolt, weld or rivet on site, helping to speed up construction schedules and ensure reliable structural performance even under high roof loads.

Efficiency and flexibility for steel structural framing

With its high level of automation, intuitive interface and low maintenance requirements, the Sino purlin forming machine is an ideal investment for steel structural component manufacturers. It allows for greater customization, faster turnaround times and higher profit margins in the competitive construction market.
