C & Z Purlins

Product available in: Vic, Sa, Qld

Apex Purlins and Girts are roll-formed from Hi-Tensile Galvanised 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 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.

Cleat Connection		Lapped Connection (Cleatless)
The cleat connection is assembled by fastening two bolts through the web of the purlin to a cleats so that the load is supported via the web of the sections. The connections can be a single thickness to match the end connection section, or the internal support connection of a lapped connection.		A lapped connection is the fixing of purlins through the bottom and/or top flange of the purlin is used in certain variations of construction. The capacity tables are not to be used for lapped connections, for these types of connections there are more considerations (both strength and accessibility) and construction concerns that need to be considered.

LENGTHS / TRANSPORT
Apex Building Products can custom cut lengths to your requirements. Due to transport restrictions it is advisable to check with our office the maximum length.

HANDLING
Care should be taken at all times when handling Corrugated. Packs must be kept dry and stored above ground level, should the sheets become wet separate immediately and individually wipe and place in an area to dry.

COMPATIBILITY
ZINCALUME® steel sheeting is compatible with most roofing products. It is NOT recommended to use lead flashing/nails, copper or copper alloy materials with or in run-off situations.

CUTTING
Apex Building Products provides this service, however sheets may be cut using a power saw with a metal cutting blade. COLORBOND® steel sheeting must be cut with the coloured surface facing the ground. Ensure that no hot particles or debris come into contact with the COLORBOND® .

CLEAN UP
To prevent premature corrosion at the completion of each day ensure the sheeting area is cleared of all debris, including nails, rivets, rags and all cutting or drilling filings.
