The sigma purlin shape provides an efficient, robust profile that suits both short and long span conditions.
In most cases of popular building type, sag rods aren’t required (subject to wind uplift conditions)

Sleeves are required to supply continuity to the purlin section across the supporting rafters. The most popular system, double

spanning has been specifically developed to minimize the number of sleeves, thus reducing the number of components and resulting in savings in installation time and component cost.

The sleeve details have also been considered in terms of simplicity and duplication. All sleeves are an equivalent length with identical longitudinal dimensions, uniformity reducing the prospect of errors. The simplest of the purlin systems. Use where design conditions dictate that no connecting sleeves are often used, i.e. purlin within a depth of rafter.
