SPANRIB® IYSACHT DESIGN AND INSTALLATION GUIDE ^—

LYSAGHT SPANRIB® The SPANRIB® cladding system provides the benefits of long spanning, pierced-fix cladding, with excellent rainwater carrying capacity. All overlapping ribs have specially formed capillary grooves to prevent water entering at the side laps. It has been designed for commercial and industrial applications where long span and fast installation are major requirements. Each sheet requires only 3 fasteners per support, so with 820mm cover, installation is very fast and less costly. Available in Queensland. TOLERANCES Length: + 0 mm, – 15 mm, Cover width: + 4 mm, – 4 mm MAXIMUM...

Don’t place fasteners less than 25mm from the ends of sheets. END LAPPING End-laps are not...
