Z & C Purlins / Section

Purlins and Girts are roll-formed from Hi-Tensile Galvanised steel and are primarily used to provide light weight, economical, efficient roofing and cladding support systems for framed structures. It is available in a range of different sizes and configurations. C-sections have equal flanges and may be used in single spans and unlapped continuous spans in multi-bay buildings. Their freestanding stable shape allows easy handling and storage and is easily adapted for use in small and medium sized buildings as structural framework.

Z-sections feature one broad and one narrow flange allowing the two sections to fit together snugly, making them suitable for lapping. Z sections of the same depth and different thickness' can be lapped in any combination. Purlins and Girts that are lapped form a structurally continuous line along the length of the building, a factor that contributes significantly to the reduction in building costs. Downturn lip purlins are ideal in applications where environmental conditions or build up of substances like dust or grain are a consideration for special or large projects.
