Bold capacities require grade 8.8 purlin bolts. Values above horizontal line in body of table are governed by the strength of the grade 8.8 bolt.
IN = Inward load capacity. OUT = Outward load capacity. See also: Design notes for capacity tables.In mixed spans, the thicker section is used in the end spans.
