Z purlins

Standard sizes Z125 to Z300
Unequal flanges E / F nest for laps
Lip angle 95–115°
Auto-size line: H 100–400, T 1.2–4.0 mm
Oval holes 14 × 22 or 16 × 24 mm

Built for continuous roofs

Z sections have one wider and one narrower flange so two sections nest into each other at laps over the rafters. Lapped Z purlins act as continuous beams – lighter purlins for the same span, the standard secondary system for pre-engineered buildings.

C and Z purlin section dimensions — Section parameters H, E, F, L, lip angle and hole centres K.

常见问题

Why use Z instead of C purlins?

Z purlins can be lapped over rafters to act as continuous beams, which usually saves weight on multi-bay roofs.
