Glassteel is a general term for systems that combine glass with slender steel profiles, typically used for (fire-resistant) glass screens, glass facades and glazed internal walls. Its defining feature is the pairing of large glass surfaces with a minimal yet strong steel frame, producing an assembly that is transparent while remaining structurally robust.
Application
Steel-profile systems for glass construction are used where both maximum daylight and high structural or fire performance are required:
- Fire-resistant glazing. Steel holds its shape relatively well under heat, making it suitable as a framework for fire-resistant glass screens and partition walls. The required fire resistance (for example 30 or 60 minutes) is determined by the combination of tested glass and profile.
- Glass facades and curtain walls. Slender steel profiles carry large glass panes and give a clean, industrial or historic-looking facade.
- Glazed internal walls. In offices and homes, steel frames with glass divide spaces without blocking daylight; the so-called “steel look” is popular here.
Characteristics
Because the exact properties (dimensions, fire class, insulation value) depend on the specific system and manufacturer, applications must always follow the tested and certified build-up. Only then is the stated fire resistance or structural performance guaranteed.
