Product Options | Type: The product reference combines the purlin section type, either Zeta (1), Zeta II (2) or Zed (Z) and then requires values to be input based on the depth and thickness required i.e. 1/12513 refers to Zeta section, 125 mm deep and 1.3 mm thick. The following depths and thickness are available: - Depth:
- Thickness:
General:
System type: applies to all purlin profiles unless noted otherwise. - Butted: Single spanning sections without sleeves. Non continuous system, suitable where depth constraints exist and sections are fixed between supports. - Double span (Zeta and Zeta II ONLY): Double spanning sections with only a minimum number of sleeves to alternate purlins across the penultimate support. Does not give quite the same strength capacity as the Sleeved system, but with fewer components is faster to erect. Alternative to sleeved system up to 7.5m span. - Double span heavy end bay (Zeta ONLY): Similar to Heavy end bay system, but using double spanning interior purlin lengths and fewer sleeves. Does not give quite the same strength capacity as the Heavy End Bay system, but with fewer components is faster to erect. Alternative to the Heavy End Bay system up to 7.5m span. - Heavy end bay (Zeta, Zeta II and Zed ONLY): Single spanning sections with sleeves at all supports providing a fully continuous system. End bay sections and sleeves increased in gauge to compensate for the lack of continuity at the gable. Increased capacity for longer spans and/or heavier loads. Suitable as a purlin system for longer buildings with five or more bays. - Sleeved (Zeta, Zeta II, Zed and CW Section ONLY): Single spanning sections with sleeves at alternate supports and on all penultimate rafters. Sleeves act as 'mechanical hinges' to provide maximum structural efficiency for the number of components employed. Suitable for most building applications. |
