Flat Lock metal panels have been used for centuries. OVERLY Panel Systems brings that tradition forward with today’s ingenuity.

The FLP™ (Flat Lock Panel) is an overlapping, shingle-style metal panel system designed for architects and builders who need design flexibility, durability, and clean aesthetics. Whether you’re designing a bold façade, a curved surface, or a custom architectural feature, FLP™ delivers timeless style with contemporary innovation.

What Are Flat Lock Panels?

FLP™ panels are interlocking metal tiles that attach using a concealed cleat and fastener system, creating a sleek, uninterrupted surface.

• Panels are secured to the substrate with hidden cleats
• Adjacent panels lap and hook together
• Installed bottom-to-top and side-to-side for efficient construction
• Suitable for walls, façades, soffits, and complex geometries

This system offers a refined, modular look while ensuring structural integrity and weather resistance.
