The car park exterior façade is a combination of perforated and solid aluminium panels orientated to create a flowing display. The designers wanted to retain the visibility of the grain in the surface of the aluminium and therefore needed a protective coating that would not mask this subtle pattern.

Powdertech applied a semi-transparent polyester coating, referred to as a lacquer. Lacquers are available in many shades and provide the same level of protection as opaque architectural powder coatings. To remain in keeping with the pale gold shades of the stone throughout York, a pale bronze lacquer was selected. A total of six hundred and eighty four panels were coated - 1800 square metres of metal. “We have close relationships with the leading powder manufacturers who specialise in custom powders and shades, “ said Richard Besant, Director, Powdertech, “ All the powders we use are of architectural quality and provide excellent weather resistance and colour stability.”
