Flat Lock Tiles are made out of material fully supported by structural plywood. This is a system whereby two sides of the tile will form a under cloak fold and the other two sides an over cloak fold, they overlap when the tiles are joined. The upper tile hooks over the below fixed tile and locks into its final position before mechanically fixed to the plywood deck using Stainless Steel screws. Essentially this system looks like a fish scale skin, which covers the facade. Panel sizes can vary in width and lengths. Contact our team at Craft Metals for recommended standard sizes.
