Application
Standing Seam Roof Sheet
Concealed fixed roofing
Concealed fix system requires no piercing fasteners and helps provide weather tightness and superior resistance to wind uplift. With no exposed fasteners, the straight lines of your roof remain clean and smooth.

Heat Insulated clip
The original heat insulated clip allows for movement which results from the thermal effect. This minimizes the need for step expansion joints.

Design flexibility
Available in tapered and curved sheets to fulfil the most challenging design criteria. Suitable for roofs with low slopes.
Better thermal performance
Specially engineered thermal pad slides neatly onto base of the clip which can reduce or eliminate thermal bridging effects.

On-Site Roll-Forming
LYSAGHT FLEXLOK™ 400 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.

Architectural Roofing Solution
High design flexibility with multiple profile shapes and on site roll forming makes FLEXLOK™ 400 a perfect architectural roofing solution.
