Tetlow Developments Ltd recently completed an external building conservation and renovation project on an industrial unit in the Northwest. The building is the headquarters of CNC Support Ltd, Manchester. CNC Support Ltd, who carry out the service, installation and repair of CNC machinery.
The industrial building was constructed by building contractors some 25 years ago in the now ‘traditional’ manor, as have many industrial buildings in and around the Manchester area and throughout the North West.
The building consists of a simple steel portal frame with a masonry plinth to the window head height, above which the elevation is completed with corrugated sheet metal, which has been used as wall cladding. The corrugated roof is affixed to the steel portal frame in the manner of most roof cladding upon industrial buildings throughout the North West, frequently seen here in Manchester.
The client contacted Tetlow Developments Ltd for advice about how the appearance of the building could be improved upon; the existing metal cladding on the walls was looking very tired. The metal cladding had experienced levels of mechanical damage and cut edge corrosion was very evident on a significant number of the corrugated sheet metal panels.
Additionally there was also concern about the integrity of the roof cladding, as historic water ingress was evident in some areas. Upon closer inspection of the roof, it was found that there had been significant cut edge corrosion to the end of the corrugated sheet metal where this roof cladding terminates into the gutter. This cut edge corrosion was so substantial that the corrugated roofing had corroded back beyond the line of the gutter, thus allowing moisture to enter the building. In addition to this corrosion the existing steel gutters had corroded to such a degree that in sections the gutter had almost perforated.
A scope of works was agreed with the client which would ensure the aesthetic improvement of the building with appropriate corrugated sheet metal that would also make the buildings weather-tight. The existing corrugated sheet metal that made up the external elevations wall cladding was removed first and replaced with new profiled metal cladding in a new colour (goosewing grey) as selected by the client. Whilst replacing the new metal cladding Tetlow Developments Ltd also installed all the associated flashing to fully protect the building from the elements.
The corrugated roofing that had been significantly damaged by the cut edge corrosion needed to be specially treated to avoid any further corrosion from taking place. First the severely corroded sections of the roof cladding were cut back to an even line and the remaining corroded exposed surfaces were abraded to remove any friable material. The exposed areas of cut edge corrosion were then treated with a rust eater that chemically alters the state of the iron oxide, stabilising it and slowing down the corrosion process. The treated areas were then sealed with a high build epoxy paint to encapsulate the corroding areas of the corrugated roofing.
The final element of work was the repair of the galvanised steel gutters. Firstly all debris was removed from the gutters in preparation for the receipt of the new gutters. A plygene gutter as manufactured by H D Sharman (see www.hdsharman.co.uk) was then placed into the existing gutter. The gutter used was made bespoke for this project. The gutter was designed to be in one continuous piece, which strengthens the structure, mitigating any future joint failure problems.
The headquarters of CNC Support Ltd, Manchester, following the replacement of the corrugated sheet metal cladding and the treatment of roof cladding for cut edge corrosion, is now water-tight, and in addition, has the advantage of being one of the more attractive industrial buildings in Rochdale, Bury, Bolton, Stockport and Oldham area.
