LYSAGHT LONGLINE 305®

Product Description and Features

LYSAGHT LONGLINE 305® is a concealed-fixed roof cladding with bold ribs and wide pans. The standing seam ribs make a bold architectural statement, while maximising water tightness. It is available in three styles: 

• plain (flat pans);
• fluted (small creases in the centre of the pan);
• tapered (pan-width reduced by up to 50% of normal width at one end) for a sweeping fan effect, allowing curved and rounded roof shapes to be clad with ribs radiating from a central point.

It is a simple, low cost fixing that is fast, economical and effective. Please click to view images of LONGLINE 305®.

• May be used on roof pitches as low as 1 degree (1 in 50)

Note:

• For low pitches, all roof supports must be in the one plane to prevent water ponding leading to premature corrosion
