1.2 Profile
C and Z purlins produced by this line use galvanized or cold-rolled steel, thickness 1.5–3mm. Shapes include standard C and Z profiles with uniform flanges and web. Features high precision, smooth edges, and optional pre-punched holes. Applications include industrial roofing, steel frame buildings, warehouses, and agricultural structures, providing structural support and durability.
Material: Galvanized Steel / PPGI / Aluminum Thickness:1.5-3.0mm
Yield strength: 200 - 350 Mpa Tensil stress: 200 -350 Mpa

1.3 Production Process

Flow Chart:

Decoiler → Guide → Pre Punch → Roll Forming Machine → Hydraulic Cut → Out Table

Process:

The line unrolls steel coils, aligns material via guides, pre-punches holes for fast assembly, then forms profiles in a cast-iron stand roll former with chain drive. Hydraulic cutters precisely cut purlins to length. Dual-layer roll forming allows multi-size production efficiently, delivering high-precision C and Z purlins for structural and roofing applications.


1.4 Key Focus

Dual-layer design enables simultaneous production of different C and Z purlin sizes.

Cast-iron stand ensures high rigidity and long-term stability.

Chain-driven roll former provides smooth, precise forming at high speed.

Automatic size change reduces downtime, increases production efficiency.

Integrated pre-punching allows easy assembly and customizable profiles.
