Concealed Fixed Roofing

The fixing clips are first secured to steel or timber supports, then LYSAGHT KLIP-LOK® 770 is laid directly onto the clips. With no exposed fasteners, the straight lines of your roof remain clean and smooth.

Simple, Low Cost Fixing

Long, straight lengths of LYSAGHT KLIP-LOK® 700 can be laid in place and easily aligned. Fixing with our new clips is simpler and faster than ever before. The smaller number of clips for a given area provides extra economy.

Better architectural appeal

Bold ribs make appealing architectural appearance coupled with availability of multiple colour choices.

On-Site Roll-Forming

LYSAGHT KLIP-LOK® 770 can be manufactured on site using world-class mobile roll-forming technology, which not only gives single length from the ridge of the roof to the eave, but also helps to make it a leak-proof structure with better control over quality installation.

Wider Cover & better performance

Made of high tensile steel of 550 MPa yield strength, it has a wider span, with better uplift performance than all available comparable profiles.
