Glass railing is a type of railing system that uses glass panels as the infill. It is typically composed of a metal or aluminum frame that holds the glass in place, creating a barrier while still allowing for visibility. It is popular in both indoor and outdoor settings, such as on balconies, decks, and staircases. Glass railings are often used in modern and contemporary architectural designs and can add a sleek and minimalist aesthetic to a space. They can be either frameless or semi-frameless and can also be combined with other materials such as wood or stainless steel.
