Channel and Header Systems for Frameless Glass
What Are They and Why Are They Essential for Frameless Glass?
Channel and Header Systems are the heart of modern glass architecture. These are the metal profiles that continuously support the tempered glass along its edges, eliminating the need for bulky posts. They allow you to achieve the desired frameless effect, while guaranteeing structural safety against lateral load.
Channel System (U-Channel): Floor Fixing
The channel system is a robust solution that anchors the glass at its base. It is the most popular method for railings and interior glass partition walls.
Materials and Finishes: U-Channel Durability
The choice of material is vital, as the channel bears the entire weight and pressure of the glass:
Extruded Aluminum: The most common and cost-effective option. Offers lightness and high corrosion resistance. Ideal for interiors and controlled exteriors.
Stainless Steel: Maximum resistance to aggressive environments (such as coastal areas or pools). This is the highest quality investment, compatible with 304 and 316 grades.
Key Applications of the Concealed Channel
Railings: Creating that clean line where the glass appears to rise directly from the floor.
Facades and Partition Walls: For fixing large panels of fixed structural glass.
Header System (Top Rail): Support and Movement
The header system or top rail fulfills a dual function: structural reinforcement and movement guidance.
The Header as a Handrail and Structural Reinforcement
In semi-frameless glass railings, the header is placed on the top edge of the tempered glass.
Safety Function: It acts as a continuous handrail, adding rigidity and complying with load and height regulations.
Aesthetics: It can be a minimalist profile or a decorative tube, often compatible with the same finishes as the bottom channel.
