Grating panels of Stereo-3 and Terra-34, with an anti-climb aperture, were retrofitted to a multi-storey car park in Norwich to bring it up to modern safety requirements.

The six-level St Andrews car park did not meet current standards and the aim of the project was to prevent the tragic loss of life through suicides. The improvements included infill panels of Stereo-3 and a four-meter-high anti-climb Terra-34 fence around the top deck with a cranked top panel.
