The Automatic CZ Purlin Two in One Interchangeable Roll Forming Machine is a cold bending equipment that integrates the functions of the C-type steel machine and the Z-type steel machine, mainly used for efficient production of C-type and Z-type steel structural purlins. The equipment achieves continuous bending, punching, and fixed length cutting of metal sheets (such as galvanized sheets and cold-rolled steel strips) through multiple progressive roll forming processes, and is widely used in the field of steel structure construction.

Core features :
1.Infinite changeover and cutting technology
Supports quick switching between C-type and Z-type purlins, with adjustable production specifications: width of 80-300mm, waist height of 40-80mm, and plate thickness of 1.0-3.0mm. It can produce standard and non-standard plate shapes without the need to replace molds to achieve millimeter level precision adjustment.
2.Efficient automated production
Adopting a PLC frequency conversion control system to achieve fully automatic operation, the production speed can reach 15-18m/min, and the daily production capacity can reach up to 30 tons; Equipped with a hydraulic drive system, the power is stable, and the forming accuracy error is within ± 0.5mm.
3.Strong compatibility between raw materials and scenes
Can adapt to various materials of steel strips such as Q195, Q235, Q345, etc., to meet the load-bearing requirements of different building scenarios; Supporting one click type change function, a single machine can produce more than 30 specifications of purlins, suitable for various scenarios such as steel structure factories, light steel villas, photovoltaic brackets, etc.
4.Intelligence and low maintenance costs
Integrated automatic punching and fixed length cutting devices to reduce manual intervention; The equipment adopts high-strength I-beam base and alloy steel rollers, which have high durability and low maintenance costs.

Application scenarios :
• Industrial and Storage Buildings
Used for roofs and enclosure structures of steel structure factories, warehouses, and logistics centers, providing a large-span, column free spatial layout that combines load-bearing and waterproof performance.
• Light steel residential and prefabricated buildings
As the core load-bearing component of light steel villas and prefabricated houses, it meets the needs of rapid construction and flexible movement, reducing construction costs.
• New Energy and Infrastructure
Widely used in photovoltaic brackets, grain warehouses, sewage treatment plant sheds and other scenarios, suitable for complex outdoor environments, corrosion-resistant, and easy to maintain.
