Product Information

Unveil the elegance of architectural design with the Berridge Manufacturing Single Lock Zee-Lock, a standing seam panel crafted to redefine residential and commercial construction aesthetics. This two-inch high mechanically seamed panel brings a touch of sophistication to straight or curved applications, blending structural excellence with visual allure.

Crafted from robust 24- and 22-gauge steel, or 0.032 and 0.040 aluminum, the Single Lock Zee-Lock panel offers a 16-inch coverage and a choice between a sleek smooth finish or optional striations, providing designers with a canvas for creative expression. The concealed fasteners ensure a clean, contemporary look, making it an ideal choice for roofing and fascia projects.

Installation is a breeze with continuous lengths available up to 40 feet. The panel can be seamlessly formed on-site with the Berridge SP-21 Roll Former, and the Zee-Lock Seamer ensures a watertight seal with efficiency in a single pass.

Imagine a residential roof adorned with a smooth finish, embodying modern sophistication, or a commercial space featuring the optional striations, adding a dynamic visual dimension. The Single Lock Zee-Lock stands as more than a construction material — it’s a statement of style, seamlessly blending form and function for projects where architectural excellence is non-negotiable.
