interchangeable cz purlin roll forming line | cz purlin making machine for indian PEB shed & solar structure

CZ purlin roll forming machine

This CZ interchangeable purlin roll forming line is developed specifically for India’s PEB and prefabricated shed manufacturers. It fabricates both C-section and Z-section purlins, widely used for roof secondary framing, wall girts and solar support structures.

The complete production line consists of hydraulic decoiler, sheet leveller, servo feeding system, hydraulic punching station, multi-pass roll forming unit, straightening device, flying cut system and finished product run-out table. Operators can toggle between C and Z purlin profiles and adjust web width directly via HMI touchscreen, without replacing forming rollers. This cuts production downtime significantly, helping Indian fabricators handle frequent project size changes.

The machine is optimized for locally available Indian raw coils, including MS mild steel, hot-dip galvanized coil and galvalume sheet. Finished purlins satisfy IS 811 and IS 801 cold-formed steel standards to meet wind-load requirements of industrial shed projects across India. The whole frame is reinforced to cope with high-dust, continuous-shift workshop conditions common in local metal fabrication factories.

Core Features

✅ Interchangeable C & Z Purlin, Tooling Without Roller Change

Universal adjustable forming tooling. Switch between C and Z profiles and modify web width in 5–10 minutes. Perfect for PEB workshops running mixed batch orders with frequent drawing revisions.

✅ Built-In 415V / 3 Phase / 50Hz Power Configuration

All motors, hydraulic pack and PLC control system match India’s standard industrial grid. Schneider electric components are easy to source spare parts locally, minimizing production halt risk. Multi-language HMI supports English operation for on-site operators.

✅ Heavy-Duty Frame for Long Continuous Shifts

Thick welded H-beam base and cast iron forming stands reduce vibration during long-hour running. Anti-dust sealing design protects rollers and bearings from metal dust, extending service life in Indian factory environments.

✅ Servo Hydraulic Punching + Flying Shear Cutting

Automated hole punching for purlin bolt connections; flying cutting works without stopping the line. Stable hole spacing and section precision ensure easy on-site assembly for construction teams.

✅ High Wear-Resistant Forming Rollers

Rollers made of GCr15 alloy steel with heat treatment, hardness HRC 58–62. Resist scratching when forming galvanized and galvalume coils commonly sourced in India.

✅ Localized After-Sales & Shipment Support

Full FAT inspection before loading. We offer technician on-site commissioning and operator training. Spare parts can be shipped quickly to major Indian ports including Mundra, Kandla, Chennai and Nhava Sheva.

FAQ

Q: Can the machine run under India’s 415V factory power?

A: Yes, the machine is fully wired and configured for 415V / 3P / 50Hz. No extra transformer is required on your workshop side.

Q: Does the finished purlin meet Indian PEB building codes?

A: Yes. The formed purlins conform to IS 811 and IS 801, the primary standards accepted by Indian structural consultants for shed and solar projects.

Q: How much time is needed to change from one purlin size to another?

A: Adjustment is controlled by touch screen recipe, takes roughly 5–10 minutes. No roller replacement needed.

Q: What support do you get after machine arrives at Indian port?

A: Pre-ship FAT test, overseas technician commissioning and operator training, lifetime remote troubleshooting and fast spare part supply.
