River Street Tower, Manchester

OVERVIEW

6500SQM OF OPTIMA FC IN COR-TEN WEATHERED STEEL RAINSCREEN PANELS HAVE BEEN USED IN THE STATE-OF-THE-ART STUDENT ACCOMMODATION ON RIVER STREET.


As described by Architect Simpson Haugh, the student accommodation comprises three distinct volumes: a volume stepping from ten storeys fronting Garwood Street, down to five storeys facing River Street, and a 32-storey tower.


Cor-Ten, a steel alloy which forms a rust-like appearance over 18 – 36 months, was selected for the project due to its striking appearance and in tribute to the copper shades surrounding River Street’s built environment. Cor-Ten is immediately recognisable with its bright red and orange tones.


The strong textures of the Cor-Ten provide a fantastic contrast to the dark-blue glass cladding covering the inner elevations.


Originally designed for use in coal carriages in 1930s American, the name Cor-Ten was patented in 1933 by U.S Steel, deriving its name from ‘Corrosion Resistance’ and ‘Tensile Strength’.


Whilst it might look like the metal is rusting, the outer layer of the metal is actually undergoing a planned corrosion process under the influence of outdoor weather elements, which protects the metal from further corrosion over time.


Referencing the corrosion process, Sotech Specification Manager Charlie Mclaughlin said: “Cor-Ten panels developed a patina in-situ on the buildings as a response to the elements. The local climate should be ideal. It was great to do another job with Simpson Haugh, especially on a site just a stone throw from their office.”


Sotech’s Optima FC secret fix hook-on rainscreen system was installed to carry the panels, this fully tested system had the added precautions of stainless steel hooks and polyester powder coated rails to eliminate any bimetallic reaction between the Corten panels and aluminium support system.


As you can see from the project photos, the Cor-Ten panels were perforated with hole cluster patterns positioned to coordinate with extractor vent outlets in the backing wall. This is achieved through a laser cutting process.


As experts in the industry with over 30 years’ experience, Sotech wasn’t just involved at the manufacturing stage, but were engaged from design stage, offering details, advice and budget costs during the project.


With 792 bedrooms and state of the art social space, the building fills a spot in Manchester’s landscape that had been empty for years.
