Spiral staircase, curved balustrading, & premium general glass processing capabilities

In-house Glass Processing

Spiral staircase and other specialty curved glass applications require the very best quality raw materials and impeccable processing techniques. To ensure this, we process (cut, wash, polish, edge etc.) our glass in-house from premium raw glass stock direct from two of the world’s leading suppliers of float glass.

Standard Capabilities

Generally speaking, curves of increasing tightness require increasingly thinner and smaller panes of glass as illustrated in the table below (a pdf can be downloaded here: Curved Glass Specifications & Tolerances). With so many variables for spiral staircases and other curved glass applications, it is worthwhile contacting us to discuss your specific needs.
