PRODUCTION DESCRIPTION

CZ Purlin Roll Forming Machine

The purlin roll forming machine is the backbone of efficient angle bar manufacturing. It eliminates manual bending labor, reduces scrap, and delivers perfectly consistent CZ Purlin steel profiles at high speed.

What is a purlin roll forming machine and what does it do?

A purlin roll forming machine is a specialized industrial system that continuously bends metal coils (galvanized steel, aluminum, etc.) into C, Z, or U-shaped purlins. These profiles are used as secondary structural supports

in metal buildings, warehouses, and steel-framed houses. The machine automatically uncoils, levels, punches holes, roll forms, and cuts the material to length.

How fast is a purlin roll forming machine?

Production speed typically ranges from 12 to 20 meters per minute (40–65 ft/min) for standard lines. High-speed models can reach 30m/min. The speed depends on material thickness (1.5–4mm), hole punching requirements,

and whether it's a fixed-size or automatic changeover machine.

What’s the difference between a standard purlin machine and a purlin roll former with a punching system?

A standard machine only roll-forms the profile. A purlin roll former with a hydraulic punching system pre-punches holes (web, flange, or slotted holes) before forming. This eliminates secondary drilling operations,

ensures precise hole alignment, and saves 30–50% in labor costs—critical for pre-engineered metal buildings.

ADVANTAGES

1. Make different purlin size without changing rollers or spacers.

2. Quick change any size from 60mm to 250mm in 1min.

3. Pre Cutting system(also can add post-cutter),no need changing cutter for different size.

4. Easy to operate, low maintenance cost.

5. Infinite sizing from 60-250mm,help to save material.

6. Optional Punch hole at any position of purlin web and flange.6. Embossing, Logo Marking.

7. Full safety protection with cover guard, emergency switches, mistake proofing program.
