Galvanized Steel Frame Metal C Purlins Z Purlins Making Machine CZ Purlin Roll Forming Machine

It manufactures galvanized steel C (Cee) and Z (Zee) purlins (C and Z purlins) using roll forming, punching and automatic cutting.

The machine is designed for galvanized steel coils. It can typically be adapted for other coated or plain cold‑rolled steels—confirm specific material compatibility with the supplier.

Forming speed can reach approximately 10–15 meters per minute, depending on profile, material thickness and punch frequency.

Standard line components include uncoiler, pre‑feed leveling, 75 mm shaft roll forming station (H‑shape base), punching station, stress‑relieved cut frame with hydraulic cutting, PLC control and electrical cabinet.

Forming roller material: GCr15 mould steel with quench treatment; forming roller shaft diameter: 75 mm. Cutter material: CR12 mould steel with quench treatment.

The machine uses a PLC and frequency converter for control. Mitsubishi or Siemens control systems are available for stable performance and simple operation.

Main motor power is 15 kW and the hydraulic unit motor is 5.5 kW. Electrical voltage is supplied per customer requirement—specify your local voltage/frequency when ordering.

Small Z purlins (less than 120 mm) are produced with a special design to be very straight and resist twisting. Rollers are CNC processed to ensure high dimensional accuracy; exact tolerances depend on profile and material.

Yes. The machine integrates a punching station for hole patterns and an automatic hydraulic cutting unit; the cut frame is stress‑relieved to avoid deformation during long production runs.

The roll forming section with punch machine weighs about 9 tons. Exact footprint depends on the customized configuration; request layout drawings for precise dimensions.

Yes. Profile dimensions, hole patterns and some structural elements can be customized. Tooling (rolls, cutters, and guides) is modified to match the required purlin dimensions and material thickness—provide your required profile drawings when ordering.

Routine maintenance includes regular cleaning, lubrication of bearings and shafts, inspection of roll tooling, periodic checking of hydraulic oil and electrical connections, and prompt replacement of worn cutters or punches. Follow the manufacturer’s maintenance schedule for best results.

Most suppliers offer installation, commissioning and on‑site or remote operator training. Confirm the scope, duration and any additional travel or service charges with the seller before purchase.

After‑sales support typically includes technical assistance, spare parts supply and a standard warranty period—terms vary by supplier. Ask for warranty length, spare parts list, response times and service contract options.

Request a quotation by supplying desired purlin profiles (drawings or dimensions), material type and thickness, expected production speed, local electrical supply, and any special requirements (hole patterns, surface treatment). The supplier will then provide pricing, lead time and technical details.
