Web1 m2 aluminium at 6 mm thick (SWG 4) = £44.00 per m2. The percentage increase in the cost for the thicker aluminium can be calculated: Increase in cost = £44.00 - £30.00 = £14.00. This needs to be calculated as a percentage of the thicker aluminium: (14 ÷ 44) × 100 = 32%. This shows that 100% more steel has been bought for just 32% of the ...
