What These Components Are

Glass clamps are the fastest way to fix toughened glass panels to stainless tube or flat surfaces in balustrade, balcony, staircase, swimming pool and feature applications. Choose the clamp style based on tube diameter and glass thickness - round backs fit curved tube (42.4mm or 48.3mm), flat backs fit posts/walls with a flat face, 90° and 180° clamps fix glass at corners or in line.

Finishes Explained

316 Mirror - the premium architectural finish. Marine-grade 316 stainless polished to a high reflective mirror finish. The choice for showcase residential, hotels, retail and feature installs where appearance matters as much as durability.

316 Satin - the trade standard for external and marine work. Marine-grade 316 stainless with a brushed satin finish - hides fingerprints, water spots and minor scratches. The default choice for balconies, terraces, swimming pools, coastal homes and commercial work.

304 Satin - the indoor/dry-environment option. Standard 304 grade stainless in satin finish - lower cost than 316, perfectly suited to interior staircases, dry-environment installs and budget-focused projects. Not recommended for outdoor or coastal use.

Specification & Standards

All stainless steel components are manufactured to BS EN 10088 stainless steel standards. 316 grade contains 16-18% chromium, 10-14% nickel and 2-3% molybdenum (the molybdenum is what gives 316 its marine-grade chloride resistance). 304 grade contains 18-20% chromium and 8-10.5% nickel. Tube and section dimensions to standard UK railing dimensions (42.4mm or 48.3mm OD round tube, 40×40mm square, 40×30mm or 60×30mm channel for glass-top systems).
