Challenge

ASF was asked to come up with a solution for a stainless steel illuminated handrail / step unit system for the One City Square project in Bradford.

There were a couple of difficulties to overcome, not least an 8-week end-to-end lead time but, on a technical note, the desired specification required square or rectangular section stainless steel, a timber handrail and linear illumination.

This created a few problems as the off-the-shelf slotted rectangular tube worked well for the lighting, but the wall thickness was too thin to cope with the natural seasonal movement from timber if fully clad.

Solution

ASF worked with LTP Lighting Integration to develop a bespoke lighting unit, so that each individual section of railing had a dedicated light, allowing for some movement in the system without compromising the lamp. Expansion gaps are also built into the timbers and 'celebrated' rather than trying to hide them. A combination of square and rectangular section stainless steel was used, with a flat bar horizontal infill to create a style-focused end product that remained in line with the client's requirements.

Result

The outcome is a very modern system that celebrates an area of 'Spanish Steps' alongside a longer, wider stairway. Lighting meets the required standards for both brightness and colour temperature and the timber capping sections offer not only a decorative element but also a finish that is warm to touch.
