| 1.1 Production Line | ||
| This roll forming production line targets metal building manufacturers, construction companies, and structural steel suppliers. It offers high efficiency, precision, and flexibility for producing multi-size C and Z purlins. The automated size change and dual-layer design improve productivity while minimizing downtime, serving demanding industrial and commercial roofing markets. | ||
|
|
|
|
| 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. |
