C Purlin & Z Purlin
C Purlin and Z Purlin are widely used structural components in steel structure buildings. They serve as important support elements for roofing systems and wall cladding systems, providing excellent load-bearing capacity and structural stability for industrial and commercial buildings.
| Model | Type | Description |
| CP-80 | C Purlin | Light duty purlin for small structures |
| CP-100 | C Purlin | Standard purlin for roofing support |
| CP-120 | C Purlin | Medium load structural purlin |
| CP-160 | C Purlin | Heavy duty structural purlin |
| ZP-120 | Z Purlin | Overlapping purlin for large span buildings |
| ZP-160 | Z Purlin | Heavy load purlin for industrial roofs |
| ZP-200 | Z Purlin | High strength purlin for long span structures |
