Double-Lok®
Mechanically Seamed Roof Panel

Product Description

Description: A metal standing seam roofing product attached to sub-framing using a variety of concealed, interlocking clips that provide for minimum panel penetrations. This panel can be used on new construction as well as retrofit on existing structures. This panel design provides a high degree of weather tightness and has been tested by independent laboratories in accordance with ASTM E283 and E331 (for air infiltration, water penetration, and wind uplift).

Gauge: 24 (Standard) with 22 gauge available on request

Lengths: 55' maximum is standard but longer lengths available by special request.

Fasteners:Concealed fastening system.  The clips are available as floating or fixed.  Two different clip heights are available to allow for thermal blocks.

Finish: Galvalume® and Royal K-70® Panel Colors

Usage:New and retrofit applications.

Limitations: Recommended for roof slopes of 1/4:12 or greater. When using the fixed clip we recommend for double slope buildings 200' wide or less and single slope buildings 100' wide or less.(May vary upon extreme weather conditions.) Oil-canning is not a reason for rejection.
