U-Channel System
A base-mounted glass railing system using an extruded aluminum channel (U-shaped profile) that receives the glass panel at its bottom edge, creating a frameless appearance without visible posts.
Technical Details
U-channel systems (also called base shoe or shoe channel systems) consist of an aluminum extrusion anchored to the substrate (concrete slab, steel beam, or wood structure). The glass panel is set into the channel with structural shims and secured with a compression plate or set screws. Wet-glazing with structural silicone or dry-glazing with gaskets fills the remaining gap. This method provides a clean, minimalist appearance while meeting structural requirements.
Frequently Asked Questions
What is the advantage of U-channel glass railings?
U-channel systems eliminate visible posts, creating a clean frameless look that maximizes views. The glass appears to float from the floor or deck surface. They are ideal for modern architectural designs and luxury applications.
How is glass secured in a U-channel?
Glass panels are set into the aluminum channel with structural shims for alignment, then secured with compression plates or set screws. The gap is filled with either structural silicone (wet glazing) or compression gaskets (dry glazing).
