elZinc Rainbow® Gold zinc roof is the outstanding feature of The Bund, which won the UK Roofing Awards 2018 Industry Choice category for Longworth Building Services.
Longworth partnered with SIG Zinc & Copper to install the stunning roof for The Alchemist, a new restaurant set between the towers of MediaCityUK and Michael Wilford’s The Lowry in the heart of Salford Quays, Manchester. The sharp lines and angles that make up the roof’s complex angular polyhedron shape are enhanced by the gold zinc, both of which have helped create a new landmark in the area.
elZinc Rainbow® is manufactured from titanium zinc that complies with the European standard UNE-EN 988. It is available in a range of colours, and with the exception of the gold finish, is made by applying mineral pigments to elZinc Slate®. The 35µm organic coating also provides a durable for additional protection against corrosion.
The zinc roof cladding was installed over an Admaster composite panel which provides both insulation and acoustic attenuation. Longworth Building Services developed a bespoke installation system, utilising specialist mechanical handling and access equipment. This included a pontoon scaffold over the quay to form the structure using 12m long, 500kg composite sheets.
Building from just primary steelwork outwards, a bespoke designed secondary-steel frame was required to creation the many acute angles and required close cooperation between Longworth and Reid Architects using the latest 3d modelling software to design and construct the incredibly complex angular polyhedron shape of the building.
Longworth received more than 1,500 votes from across the roofing sector to win the first ever Industry Choice Award at the UK Roofing Awards 2018.
