The High Speed Automatic C Purlin Roll Forming Machine is an automated specialized equipment that continuously processes metal coils (such as galvanized steel, cold-rolled steel, etc.) into C-shaped steel purlins through cold bending forming processes. The typical production process includes full automation operations such as automatic feeding, leveling and feeding, continuous punching, roll forming, fixed length cutting, and finished product output. The entire production line usually consists of passive loading racks, leveling devices, punching devices, forming machines, hydraulic cutting devices, PLC control systems, and discharge platforms, among other components.

Main application scenarios：

The C-shaped purlin products produced by this equipment have good bending and compression resistance, as well as good flatness, and are widely used in the following fields:

1. Industrial and Logistics Buildings

• Roof load-bearing structure and wall support of industrial plants and workshops

• Roofs and wall rafters of warehouses and logistics centers

• Large industrial facilities such as locomotive depots and aircraft hangars

2. Public and commercial buildings

• Roof load-bearing capacity and wall support of exhibition halls and sports venues

• The framework structure of commercial buildings such as supermarkets, shopping malls, and hotels

• Public facilities such as theaters, market flower sheds, etc

3. Residential and lightweight buildings

• The purlin structure of residential roofs

• Steel structure frame for prefabricated houses and activity board houses

• Supporting structures for agricultural greenhouses and farmhouses

Core Features：

1. High speed and efficient production
The molding speed of the equipment can usually reach 8-18 meters per minute (excluding punching and cutting time), and some high-end models can reach speeds of 60-120 meters per minute without punching. Calculated on an 8-hour shift basis, the single shift production capacity can reach over 4800 meters.

2. Fully automated control
The whole machine is controlled by PLC (Programmable Logic Controller) and touch screen human-machine interface. The operator can preset parameters such as product length, quantity, and punching position on the touch screen, and the equipment automatically completes the entire production process from feeding to finished products. Simultaneously equipped with multiple safety protection functions, effectively avoiding safety accidents.

3. Flexible changeover and multi-purpose use of one machine
The modern high-speed automatic C-type purlin machine supports rapid and even stepless type changing – it can adjust the profile specifications at the millimeter level without changing the mold (such as web width of 80-300mm, waist height of 40-80mm, etc.). Some models also support C/Z steel interchange, and the same set of equipment can produce C or Z purlins through simple adjustment. The replacement time for high-end models can be shortened to 30 seconds to 3 minutes.

4. High precision molding
The roller is made of high-grade bearing steel such as GCr15, which has undergone quenching, precision grinding, and chrome plating treatment, and has extremely high hardness and wear resistance. The molding accuracy can be controlled within ± 0.1mm; The accuracy of the flying shear cutting system can reach ± 0.5mm.

5. Durable and sturdy
The fuselage is made of high-strength I-beams or steel plates welded together, and undergoes aging treatment to eliminate internal stress, ensuring that the fuselage does not deform during long-term use. The core components have a long service life, and some high-end models are designed to have a lifespan of over 15 years.
