Strength and Durability with Structural Integrity

LYSAGHT Roof Purlins and Girts are light-weight structural steel members, designed in accordance with the As/Nzs 4600: 1996 Cold Formed Steel Structures, utilising high Strength Zinc-coated Steel. Available in ZED-plusTM Sections, these roof purlins can be used over single spans or un-lapped and lapped continuous spans in multi-bay buildings. Lapped continuous spans result in considerable capacity increase in the system. LYSAGHT’ CEE-plusTM Sections may be used in
single spans, and un-lapped continuous spans in multi-bay building, and are ideal as eave purlins or where compact sections are required for detailing.

Greater Spanning Capability

Cold formed galvanized purlins have a minimum yield strength of approximately 60% greater than that of hot rolled steel that is typically used for purlins. This high strength – to – low weight ratio in most applications allows extra spanning capability for the most cost effective structures.

Easier to Handle

The high-strength to low-weight ratio makes the product easier to handle, both during transportation and erection.

Lightweight, Quick and Easy Installation

The pre-punched sections of the high strength galvanized cold rolled sections reduces fixing time by using self-drilling, self-tapping screws and standard bolts.

Longer Life

LYSAGHT’ Purlins are made from Zinc and Zn-Al alloy coated steel. They have greater corrosion resistance and lasts longer under extreme weather conditions.
