Description of  CZ Purlin Roll Forming Machine

Cangzhou Zhongtuo offers a variety of purlin and girts forming machines, designed to accommodate profiles ranging from 100mm to 400mm in both Z and C shapes. These machines provide options for cutting to length and can be configured as either punched or unpunched.

C-Shape Purlin Roll Forming Machine

A C purlin roll forming machine is a specialized piece of equipment that continuously produces C-shaped steel channels from galvanized or cold-rolled steel strips. The process involves several stages, including feeding, hole punching, bending, and cutting. This machine is fully automated and features a user-friendly Human-Machine Interface (HMI) panel, making operation straightforward. It is comprised of several key components: a decoiler, sheet guiding equipment, a roll forming section, a PLC control system, hydraulic cutting, and a collection table.

C purlins, also known as Cee purlins, are structural elements with a C-shaped cross-section. They function as horizontal beams designed to support the roof and wall joists of a building shell structure. Positioned between the roofing sheets and the building, C purlins provide essential support to keep the sheets securely attached and in place.

Z purlins, also roll-formed from GALVASPAN steel, feature one broad flange and one narrow flange. ZTRFM’s Z Section purlins are designed to interlock neatly, allowing for lapping at internal supports. This design facilitates the creation of structurally continuous purlin lines across the length of the building.

Main machine Features:

Zhongtuo Machinery Factory specializes in manufacturing C purlin roll forming machines, designed to produce C-shaped purlins ranging from 3 inches to 12 inches in size. We also offer CU and CG purlin machines, with options for punched holes or without. Please share your specific requirements, and we will customize the roll forming machines to meet your needs.

For transitioning between C and Z purlins, our design allows for easy adjustment of the upper layer rollers in relation to the lower rollers using a handwheel that can turn 180 degrees. To accommodate different sizes, the entire roller line can be moved with a bottom press control, making the process efficient and time-saving.

Advantages of Our Purlin Machines:

1.Precision Engineering: Our specialized design enables the production of small Z purlins (less than 120mm) that are exceptionally straight and resistant to twisting. Unlike similar small-sized Z purlins from other manufacturers, which often exhibit straightness issues, our machines consistently produce high-quality purlins.

2.Robust Construction: Featuring a robust 75mm solid shaft and a base frame made from H-shaped steel, our machines are built to withstand long-term production without warping. This construction ensures the consistent quality and durability of the purlins produced.

3.High-Quality Rollers: The rollers are manufactured from GCR15 material and are precisely machined using CNC technology. This level of precision guarantees that the rollers are accurate, which directly translates to the precision of the final purlins produced.

4.Stress-Relief Treatment: Our cutting frames undergo a stress-relief treatment to prevent deformation during extended production runs. This ensures smooth C purlin formation and maintains the integrity of the purlins throughout the manufacturing process.

5.Advanced Operating System and Speed: We utilize a Siemens operating system, ensuring stable performance and ease of operation. Our machines can achieve forming speeds of  15-20 m/min, enhancing overall production efficiency. The C-Z purlin machine, equipped with a punching unit, has an approximate weight of 9 tons, indicating its robust design.
