Snap Lock (Slotted Flange)

The Snap Lock with Slotted Flange is a premium standing seam profile designed for those who demand a sleek, modern aesthetic without visible screws. As a concealed fastener panel, it offers a clean, uninterrupted surface that is highly sought after for high-end residential homes, upscale commercial projects, and contemporary architectural designs.

The defining feature of this panel is its integrated slotted flange, which allows the panel to be fastened directly to the deck through pre-punched slots. This design allows for natural thermal expansion and contraction of the metal—essential for preventing “oil canning” or buckling during temperature changes. Once the first panel is secured, the next panel simply snaps over the flange, hiding the fasteners completely and creating a continuous, weather-tight barrier.

With its tall, narrow ribs and fastener-free finish, the Snap Lock system provides maximum protection against the elements while offering a sophisticated, high-performance look that lasts a lifetime.
To meet specific architectural needs, this panel can be customized with various surface profiles. Whether you prefer a perfectly smooth look or added structural texture, we can manufacture the panel with clip relief, bead ribs, pencil ribs, striations, or a traditional flat pan.

Note: Oil canning is not a cause for rejection
