The Customized C Purlin Roll Forming Machine and Z Purlin Making Machine provide an efficient manufacturing solution for steel structure companies, building material suppliers, and metal profile manufacturers. This production line processes galvanized steel coils into accurately shaped C and Z purlins through continuous roll forming, helping manufacturers achieve consistent profile dimensions and stable production quality.
Designed for customized steel profile production, this C/Z Purlin Roll Forming Machine handles material thicknesses from 1.2mm to 3.0mm. Its 18 forming stations gradually shape the steel strip, while an 80mm main shaft supports stable roller operation. Furthermore, the hydraulic cutting system delivers accurate cutting according to the required profile length.
Manufacturers can configure the machine according to their C purlin and Z purlin drawings, including profile dimensions, flange structures, lip sizes, punching positions, and production requirements. Therefore, the equipment can support different steel building projects rather than limiting production to one standard profile.
Machine Structure and Key Technical Features
The machine combines coil feeding, roller forming, transmission, hydraulic cutting, and electrical control into one production system. Each section performs a specific function, allowing the operator to manage the manufacturing process efficiently.
18-Station Roller Forming System: The 18 forming stands gradually bend the galvanized steel strip into the required C or Z profile. This progressive forming process reduces sudden material deformation and helps maintain consistent profile geometry throughout production.
80mm Main Shaft: The machine uses an 80mm shaft diameter to support the forming rollers. A stable shaft structure helps maintain roller alignment and forming accuracy when processing steel materials between 1.2mm and 3.0mm thick.
Cr12 Roller and Mould Material: The forming rollers use Cr12 tool steel, which offers good wear resistance and supports long-term industrial production. The roller configuration can be customized according to the required C and Z purlin cross-sections.
Chain Drive Transmission: The chain-driven system transfers power through the forming stations. This mechanical transmission arrangement supports continuous material feeding and forming during normal operation.
Hydraulic Cutting System: After the profile reaches the preset length, the hydraulic cutting unit completes the cutting operation. This system helps manufacturers produce purlins with consistent lengths for subsequent assembly and installation.
Flexible PLC Control: The electrical control system can be configured with Mitsubishi, Siemens, or other suitable control components according to customer requirements. Operators can manage production settings and coordinate the machine’s working sections through the control interface.
Working Process of the C/Z Purlin Making Machine
The automatic C purlin and Z purlin production line transforms flat galvanized steel coils into finished structural profiles through several continuous manufacturing stages.
1. Coil Loading and Feeding: The operator loads the galvanized steel coil onto the decoiler. The feeding section then guides the steel strip into the forming machine while maintaining stable material alignment.
2. Progressive Roll Forming: The steel strip passes through 18 forming stations. Each roller stand gradually changes the material shape until it reaches the specified C or Z purlin cross-section.
3. Profile Dimension Control: The forming rollers work together to maintain the required web, flange, and lip dimensions. Manufacturers can customize the roller tooling based on technical drawings and material specifications.
4. Hydraulic Length Cutting: The cutting system separates the continuously formed profile according to the preset production length. This process prepares individual purlins for handling, storage, and installation.
5. Finished Product Collection: Workers collect and inspect the finished profiles. They can check the overall dimensions, cutting edges, straightness, and surface condition before transferring the products to the next production stage.
The standard production speed is approximately 10–20 meters per minute, depending on the profile design, material thickness, and actual production configuration.
Applications of C Purlins and Z Purlins in Steel Construction
C purlins and Z purlins play important roles in modern steel building systems. Their lightweight structure, practical installation characteristics, and structural versatility make them suitable for a wide range of construction projects. With a customized C/Z Purlin Roll Forming Machine, manufacturers can supply different profile specifications for various building requirements.
Industrial Steel Buildings: Steel factories, workshops, and manufacturing facilities commonly use C and Z purlins as roof and wall support members. These profiles help support roof panels, wall cladding, and secondary structural components.
Warehouse and Logistics Centers: Large warehouses require reliable roof support systems and efficient construction materials. C and Z purlins provide practical solutions for roof framing and wall structures, helping contractors assemble steel building systems efficiently.
Commercial and Agricultural Buildings: Commercial workshops, farm buildings, equipment storage facilities, and agricultural sheds can also use roll-formed purlins. Manufacturers can adjust the profile specifications to meet different building designs and load requirements.
Roofing and Wall Cladding Systems: C and Z profiles support metal roofing sheets and wall panels in many prefabricated steel structures. Their formed sections provide practical mounting surfaces for building envelope materials.
Steel Structure Manufacturing: Steel fabrication companies can use customized purlin profiles in prefabricated buildings, industrial extensions, agricultural structures, and other engineered construction projects. A dedicated roll forming line helps manufacturers maintain repeatable production dimensions across different orders.
