What size bridging is required for a purlin roof?

Alternative hole sizes, shapes and centres are possible, subject to enquiry. Stramit recommends that bridging be installed such that the maximum unbraced length is 20 x D (where D is the purlin web height), or 4000mm whichever is the least. In addition to enhancing purlin performance this requirement assists with the erection of roof sheeting.
