Glass Capping Rails FAQs

What does a glass capping rail do?

A glass capping rail is a U-shaped profile fitted over the top edge of a compatible glass balustrade panel to create a clean finished edge and continuous top rail appearance.

Should I choose stainless steel or aluminium?

Stainless steel is typically chosen where higher corrosion resistance and a heavier architectural finish are required, while aluminium offers a lighter-weight alternative that can be easier to handle and install. The correct choice depends on the project specification and compatible glass system.

Are glass capping rails suitable for external use?

Yes. Suitable options are available for both internal and external glass balustrade applications, depending on the selected material and specification.

How do I choose the correct size?

Glass capping rails must match the thickness of the glass panel being used. Always confirm the glass specification before ordering.

Can glass capping rails form part of a handrail system?

Some systems are designed to function as a top rail or handrail detail when used with compatible components. Always check the project specification before specifying.
