1.0mm BMT: G550, Z275
1.2mm BMT: G500, Z275
1.5, 1.9, 2.4 & 3.0 mm BMT: G450, Z275

LYSAGHT® Cee sections

LYSAGHT® Cee sections may be used in single spans and unlapped continuous spans in construction with the purlins butted to internal supports. They are ideal as eave purlins or where compact sections are required for detailing.


LYSAGHT® Zed sections

LYSAGHT® Zed sections, with one broad and one narrow flange are designed to nest neatly and are intended for lapping at internal supports. They may be used over single spans, unlapped and lapped continuous spans in construction. Lapped continuous spans result in a considerable capacity increase in the system.
