General information



Flat lock panels offer a simple yet elegant roofing solution that provides a longitudinal flat seam. The system uses a simple interlocking fold on all four sides and can be installed either horizontally or vertically.
This roofing method is often used alongside roof tiles and roof shingles to enhance the building’s aesthetic and functional qualities. While roof tiles are known for their durability and traditional look, roof shingles offer versatility and a range of design options.
This solution is suitable for all buildings up to 30 m. The pre-formed panels are easy to install, making them a practical choice for modern roofing needs.

 

Support

The support must be:

  • Rigid and continuous,
  • Meet loading requirements in conformity with a minimum pull out strength of 50 daN for each clip,
  • Rest on at least 3 bearing structure elements,
  • Have no protruding elements.


Areas of application

Can be installed horizontally and vertically


Flat roofs with slope of ≥ 5% et ≤ 173%


  • ANTHRA-ZINC
  • QUARTZ-ZINC
  • Natural zinc

Description

Designed to be field assembled in sequential installation. A 20 mm continuous ventilation gap must be left clear beneath the substructure. Continuous ventilation openings are made at the top and bottom.

Lay the panel on the structure

Flat lock panels are installed from bottom to top for both vertical and horizontal laying.

Vertical From left to right - recessed joint on right side
Horizontal From right to left - recessed joint always on top to ensure it is waterproof

 

Installation of clips

Clips have a dual function :

  •    Ensuring the mechanical resistance of the entire roof
  •    Allowing free expansion of the metal

Galvanised Steel clips Thickness: 0.5 mm. The clip is pre-punched with counter-sunk holes for attachment. Designed to withstand negative load requirements.

 

Flat lock panel is based on factory formed custom sized rectangular shaped VMZINC elements featuring a formed interlocking welt at all edges. They are installed by engaging the lower edge of each panel in the upper edge of the panel below and mechanically attaching the panels to supports using concealed clips located under the upper edges of panels.
