Rainscreen and the benifits of specifying aluminium
1st November 2017
This month we look at why aluminium is the preferred choice of material for architects.
•Resistant to corrosion - Corrosion does not affect aluminium due to it’s protective oxide coating.
•Fire class - A1 - EN13501-1
•Light weight and strong - Weighs in at about the third of the weight of steel. High strength-to-weight ratio
•100% recyclable -. Re-melting of aluminium requires 5 % of the energy required to produce the primary metal and won’t lose any of it’s quality in the process
•Flexible - Aluminium is one of the easiest metals to bend, curve and fabricate.
•Alloy 1 to 7 series offers different levels of strength, workability, weldability, machining and corrosion resistance.
•Finish either (ppc) polyester powder coated, pre painted, anodised or mill •
•Available in RAL, B.S. anodised colours
•Perforated or punched to image
•Sheet or coil fabrication up to 2000 x 6000mm
•Thickness from 0.3mm to 5mm
EXAMPLE of durability - The statue of Eros was cast in high purity aluminium, and erected in Piccadilly Circus in 1893. For the first half of the 20th century, London had a very highly polluted atmosphere. Furthermore, the traffic density in Piccadilly Circus was probably as high as anywhere in the world. At the time of the Coronation celebrations in 1953, the statue was cleaned. On removal of the surface grime it was found that the metal was in excellent condition, with no evidence of pitting or corrosive attack.
