Notes to load capacities table:
Load capacities have been calculated on the basis of the top flanges being at 90º to web
Load capacities for one- and two-bridging cases assume roof sheeting attached to top flange
Load capacities for fully bridged case assume roof sheeting attached to top flange and wall sheeting attached to bottom lip
For detailing, note that mounting face is 12 mm behind front face
Standard LYSAGHT® M12, grade 4.6, purlin bolts to be used
The tables assume the use of a LYSAGHT® bridging system and LYSAGHT® bolts.
