Aluminum Connectors for Multiwall Polycarbonate Sheeting
Aluminum connectors are crucial for securely joining multiwall polycarbonate sheeting, providing reliable support and enhancing the durability of your structures. The aluminum U and H Cap and Base systems detailed below are specifically designed for use with multiwall polycarbonate panels. Available in various finishes, including mill, bronze, and anodized options, these connectors ensure a polished look while ensuring functionality.
The extrusions come in several shapes, including “U” end caps and joining “H” shapes. Additionally, a two-piece joining extrusion is offered, which consists of a base fastened to the frame and a cap that snaps in place to hold the sheets securely (cap and base). These profiles are non-structural and rely on the structure’s frame for support. Unless specified otherwise, the aluminum cap and base systems do not require any gasket material.
