What Is the Difference Between Top-Fix and Side-Fix Aluminium U Channel?

Top-fix aluminium U channel is secured to the top of a structural surface, such as a floor, concrete base or suitable parapet. Side-fix U channel is attached to the vertical face of a supporting structure. The appropriate option depends on the installation layout, available fixing surface, structural requirements and balustrade design.

When Should You Use Top-Fix Aluminium U Channel?

Top-fix aluminium U channel is suitable when a strong, level horizontal surface is available for mounting the glass balustrade. It is commonly considered for balconies, terraces and raised patios. The supporting structure must accommodate the specified fixings and loads, and the installation must follow the manufacturer's requirements.

When Is Side-Fix Aluminium U Channel Better?

Side-fix aluminium U channel can be useful when the glass balustrade needs to be mounted to the face of a structural slab or balcony edge. This arrangement can preserve usable floor space and create a clean appearance. The supporting structure, edge distances, fixings and required load capacity must be checked before installation.
