Total Roofing & Cladding


The flatlock profile is a flat sheet with four folded edges in its most basic form. Because it has limited structural strength, it requires a plywood substrate for support, yet its frail state gives a nice pillowing effect and fantastic visual texture. It is ideally suited to contemporary design and will compliment any building if used sympathetically. Flatlock can be put horizontally, vertically, and in virtually any design.
The profile is installed with hidden screws and clips, giving it a thin, elegant look unlike any other profile.

  • Low maintenance compared to other materials

About Flatlock Cladding

Standard panel widths for Aluminium or Colorbond are 330mm, and for Zinc, they are 430mm. Panels are available in sizes up to 3 meters. These are designed to minimize wastage owing to coil widths (wider panels are available but may result in distortion or oil-canning). 

Flat Lock Panels are a basic yet elegant cladding option that gives a horizontal or vertical flat seam comparable to shiplap. On all four sides, the method uses a basic interlocking fold.

Installation of Flatlock Cladding

Flat Lock Panel is a wall system that is made up of factory-formed panels that are custom-sized into rectangle, square, or diamond forms and have a created interlocking welt around all sides. They’re put together by engaging the bottom edge of each panel in the top edge of the panel below and mechanically fastening the panels to the supports with concealed clips hidden behind the upper edges of the panels.

Factory produced clips, fasteners, flashings, and finishing elements are all part of the system. The wind loading determines the distance between the concealed clips, which are typically separated at 300mm centers for residential buildings.
