In Pre-Engineered Building (PEB) design, cold-formed C and Z purlins act as the primary secondary framing system transferring roof loads to main rafters.
Optimizing purlin selection yields major advantages in project speed and economy:
- High Tensile Strength: Fabricated from 450-550 MPa high-yield galvanized steel for superior load capacity at lower dead weight.
- Continuous Lapping: Z-purlins can be nested at supports to create a continuous beam effect, increasing span capacity by up to 25%.
- Pre-Punched Accuracy: CNC punching guarantees pinpoint hole alignment, eliminating on-site drilling and speeding up erection schedules.
Hexafab provides custom roll-formed C and Z profiles tailored to exact structural drawings, complete with anti-sag rods and cleat accessories.
