Piazza-25 projectile-proof architectural grating; Stereo-3 architectural grating
Buchanan Galleries is a major shopping centre and 10-storey car park in a prominent city centre location, adjacent to the Royal Concert Hall in Glasgow.
The west elevation of the Buchanan Galleries car park, which is immediately adjacent to the main Glasgow–Edinburgh railway line, required a 25x25 open screen for ventilation.
Network Rail is particularly aware of the consequences of projectiles being thrown onto their tracks, and specify gratings with a maximum aperture through which a 25mm diameter sphere will not pass. This standard is applicable to screens securing enclosed areas or sites where the threat of vandalism is a potential problem.
Lang+Fulton recommend the use of Piazza-25 grating with an extra small 25x25mm aperture for locations where there is considered to be a risk of dangerous projectiles.
Piazza-25 was therefore specfied on the two Buchanan Galleries elevations that faced the railway line, in order to comply with saftey regulations.
Stereo-3 grating with a 63x132mm aperture was used for the remaining three elevations.
A total of 1300 square metres of infill panels were supplied to secure the 1000x2600 and 13700x3700mm ventilation openings.
The steel panels were galvanised and polyester powder coated.
Having worked in conformity with Network Rail specifications on several projects, Lang+Fulton has extensive experience in installing screens and gratings that reduce the risk of harm from projectiles near railway lines.
This project's design was developed by Lang+Fulton's technical office in conjunction with consulting engineers WA Fairhurst & Partners.
