FACADE, POLYESTER, Riyadh

Thousands of Powdertech coated panels installed at the Riyadh Metro

Overview

Riyadh’s new six-line metro, the world’s biggest urban rail project outside China, is one of Saudi Arabia’s most prestigious projects with leading architects including Zaha Hadid Architects commissioned to design the major stations. The infrastructure is set to make an incredible impression with sweeping canopies, light-reflecting curves, and arches of gleaming metal work.

The Riyadh Metro, costing around £14.7 billion  is expected to open in the second half of 2020 and will carry 1.16 million passengers a day in the initial phase of operation, with capacity to carry 3.6 million passengers as usage grows. 

Powdertech Operational Expertise

Powdertech is coating over 13000 panels of perforated aluminium, weighing 146 tonnes and 14,600 individually machined unique fixing brackets, all manufactured by EDM Spanwall. Each triangular perforated panel forms part of an arc and is secured by brackets at its corners, all of which are on a slightly different angle, due to the curved design. All the panels and brackets are marked with unique codes so that the appropriately angled brackets hold the panel and the panel goes into the right position on the façade. A Qualicoat Class 2 Axalta powder, RAL9006 is the chosen shade for the panelling.

The work demands a high degree of operational logistics, dealing with numerous parts and collating them correctly. Weekly batches of triangular panels and brackets are dispatched to Riyadh, all parts clearly identified, coated and delivered in sequence.”
