Double Lock Standing Seam Roofing

Double Locks Standing Seam Roofing

The Double Lock Standing Seam Roofing system is best characterised by its thin, defined lines and by its numerous detail variations, for example hips, ridges and fascia/eaves. The streamline low height of the seams (25mm and 38mm) contributes to its architectural design and offers versatility when working on more complex designs and structures.

Suitable areas of applications:

  • Flat
  • Convex
  • Tapered

  • Curved
  • Conical

  • Concave
  • Domes

Particularly suited to very large roof areas, the use of profiling and/or seaming machines for closing the longitudinal standing seam joints greatly reduces the installation time, making this this a cost-effective solution. The standing seam technique can be hand produced, reflecting the individual architect’s vision for lines, shadows and detailing, producing designs that have a long lasting perspective.

The Double Lock Standing Seam system requires 2 panel seams (male and female) to lap each other. Each panel is secured with concealed clips and then crimped securely together with the use of special tools. Standing Seam panels and seams run vertically from the top of the ridge down to the bottom of the roof or gutter line.

Widely used for its superior weather resistance in the harshest of climates, the dual crimping of the seams help seal the roof area which is often subject to coastal spray, snowfall, strong winds, and heavy rain.

Choose from a variety of products including VM Zinc, Aluminium, Copper and coated steel. Special paint coatings like Coolmax® COLORBOND® steel  can help reduce the annual cooling energy costs of your building by up to 7.5%, compared to regular COLORBOND® steel.
