Riyadh Metro

Powdertech coated over 13000 panels of perforated aluminium, weighing 146 tonnes and 14,600 individually machined unique fixing brackets for Riyadh’s new six-line metro, the world’s biggest urban rail project outside China and one of Saudi Arabia’s most prestigious projects.

Each triangular perforated panel formed part of an arc to be secured by brackets at its corners, all of which were on a slightly different angle, due to the curved design. All the panels and brackets were marked with unique codes so that the appropriately angled brackets were attached and the panel fitted correctly on the façade.
