Perfecting Steel Frame Fitment for Glass Floors at Glass Floor Systems Ltd

At Glass Floor Systems Ltd, we specialize in crafting a diverse range of glass flooring solutions—fixed glass floors, hinged wine cellar glass floors, and glass well covers—designed to enhance safety, style, and functionality. A critical aspect of these installations is the fitment of the steel frame, which provides structural support and seamless integration for our toughened and laminated glass. Whether you’re installing a fixed glass floor in a commercial space, a hinged wine cellar glass floor for basement access, or a glass well cover in a garden, proper steel frame placement is essential. In this blog, we’ll outline our recommended approach, address alternative methods, and offer practical advice to achieve the perfect fit for your project.

The Advantage of Flush InstallationWe strongly recommend installing the steel frame flush with the floor level for all our glass flooring products. This technique ensures a smooth, hazard-free transition from your existing floor—whether tiles, decking, or paving—to the glass surface, enhancing both safety and aesthetics. For fixed glass floors, a flush frame ensures even weight distribution, while hinged wine cellar glass floors benefit from improved hinge operation and a polished look up to 2300 x 1100mm for electric models. Glass well covers gain optimal light penetration and stability when the frame is level, avoiding shadows or uneven edges. Our UKCA-certified steel frames are designed with this flush fitment in mind to meet the highest standards.Alternative Installation ApproachesHowever, not all installations follow this recommendation, as some of our gallery images demonstrate. Many DIY enthusiasts find it easier to finish the floor opening in advance and then place the steel frame over the top, sliding the glass panel into position afterward. While this method simplifies the process and allows flooring to be completed while awaiting the glass product, it creates a potential trip ledge where the frame sits above the floor level. This approach is not recommended, especially in high-use or prominent walkways where safety is critical, such as main hallways or commercial entrances. It may be acceptable in less frequented areas, like a room’s corner or an out-of-the-way spot, but caution is advised to avoid hazards.Tips for Optimal Steel Frame FitmentTo achieve the best outcome, whether you’re a professional installer or tackling a DIY project, consider these tips:
  • Get in touch! We can provide advice and make sure you get the product you need, even if a custom frame is required. A drawing is always provided for all glass well covers, fixed glass floor and wine cellar doors so you can check in advance how it will fit and make any adjustments required. 
  • Accurate Measurements: Double-check dimensions to ensure the steel frame aligns perfectly with your floor opening, especially for custom sizes like large wine cellar doors.
  • Level Surface: Use a spirit level to confirm the frame is flush, preventing uneven glass placement that could affect safety or appearance.
  • Professional Support: For complex installations, contact us at sales@glassfloorsystems.co.uk or 0114 229 1578 for guidance or installation assistance.
  • Safety First: If opting for an elevated frame, add a non-slip treatment or barrier in high-traffic areas, and review our FAQs for additional safety tips.
By prioritizing a flush installation, you’ll maximize the safety and visual impact of your glass flooring, whether it’s a fixed floor, hinged wine cellar glass floor, or glass well cover.
