Installation stages for VM ZINC® PLUS Flat lock panel:

Designed to be field assembled in sequential installation.

1. 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 .

2. 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 a wall system based on factory formed custom sized rectangular shaped VM ZINC® 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.

The system includes a full range of factory formed clips, fasteners, flashings and finishing elements.
