Z & C Purlins

Purlins and Girts are roll-formed from Hi-Tensile Galvanised steel and are primarily used to provide lightweight, 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. Apex offers the added flexibility of downturn lips and adjustable top flanges for all sizes. 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, Apex is able to customise sections outside the standard range to suit your individual requirements.


MATERIALS

    Purlins and Girts are roll-formed from a Galvanised, high strength, steel strip complying with AS1397.
    Minimum yield stress: 450Mpa. Standard base steel thickness: 1.0, 1.2, 1.5, 1.9 and 2.4
    Zinc coating of Z350 (350g/m2) minimum coating mass) is the standard coating class provided.
    Other coatings, grades and materials may be available, subject to inquiry.


NESTING CHANNEL

Its also called as lipless C Purlins they allow for use with our standard range of C section purlins slotting into them. It is Manufactured from high tensile galvanised steel they accommodate C Purlins from 100-250mm web height. They are the perfect solution for many applications such as mezzanine floors or awning and patio systems where the purlin framing can be installed in one plain minimising the height required.
