PURLINS & GIRTS

Apex Purlins and Girts are roll-formed from Hi-Tensile zinc-coated steel. They are primarily used to provide lightweight, economical, efficient roofing and cladding support systems for framed structures. Apex Purlins and Girts are available in a range of different sizes and configurations.
C-sections have equal falnges 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 laped in any combination.

Purlins and Girts that are lapped form a structuraly 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 a build up of substances like dust or grain are a consideration. Fascia purlins angled to suit the roof slope and an optional downturn lip for wall sheet attachment are available in long length one-piece sections.

MATERIALS
