For Glass

About Glass Railing Posts

A glass railing post is a stainless-steel vertical upright designed to hold glass panels as the infill of a balustrade, creating a transparent barrier on balconies, terraces, mezzanines and staircases.

The glass is secured to the post either by integrated glass adaptors (through-bolt point fixings drilled into the glass) or by glass clamps, and a handrail sits on top to complete the system.

Strofix supplies 21 glass railing post systems in flat (40×40 mm) and round (Ø42.4 mm) post profiles, for flat-surface and stair installations, all in AISI 304 or AISI 316 stainless steel with a satin finish.

Multiple system variants are available within each profile and surface combination, differing in glass-adaptor arrangement and the number of fixing points per post.

The correct system depends on post profile, installation surface, glass fixing method and the panel size and weight to be supported.

How to choose a glass railing post

1. Installation surface: flat or stairs

Flat-surface posts have a straight base for level mounting on balconies, terraces, walkways and mezzanines.

Stair posts have an angled base to follow the pitch of a staircase.

The base angle is fixed per variant — confirm whether the railing run is level or inclined before selecting.

2. Post profile: flat (40×40 mm) or round (Ø42.4 mm)

Both flat-surface and stair variants are available in a square 40×40 mm flat-sided profile and a round Ø42.4 mm tube profile.

The flat profile pairs with square-section handrails and railing components for a geometric appearance.

The round profile matches standard Ø42.4 mm tube handrails, elbows and connectors.

The choice is aesthetic and does not affect structural performance.

3. Glass fixing method: with glass adaptors or clamp-based

Systems labelled "with glass adaptors" include integrated point-fixing positions for through-bolt glass adaptors, which require pre-drilled holes in the glass panel.

Other systems are designed for glass clamp attachment, where the glass is held along its edge without drilling.

Choose based on the glass specification and the fixing method agreed with the glazier or structural engineer.

4. System variant (number of fixing points)

Within each profile, surface and fixing-method combination, multiple variants exist at different price points.

Higher-priced systems typically include more fixing-point positions or larger adaptor arrangements, providing higher hold strength for heavier or taller glass panels.

Compare the product images and specifications to match the system to the panel dimensions and load requirements of the project.

5. Steel grade: AISI 304 or AISI 316

All 21 systems are available in both AISI 304 and AISI 316.

AISI 304 is the standard grade for interior and typical exterior installations.

AISI 316 should be specified for coastal, pool and high-humidity environments where higher chloride resistance is required.
