Steel raises the roof on M&S car park
Curved steelwork has played an important role in the construction of a car park for one of the largest Marks & Spencer stores in the UK.
Main steelwork contractor for the project was James Killelea and it sub-contracted Barnshaw Section Benders to curve floor beams to ensure they had sufficient precamber to control water run-off.
Barnshaws Commercial Director Greg North said: ‘The crucial aspect of this contract was the speed of supply. We have a long-standing relationship with the steelwork contractor and they appreciate our ability to deliver large tonnages of curved steel on time. In this case it was very nearly 500t of universal beams that required a camber of between 50mm and 100mm.”
The camber in each beam was carefully calculated to allow some deflection due to the weight of the roof section while still retaining enough of a curve to prevent any standing water on the car park surface.
The sections ranged from 533 x 210 x 101UB to 533 x 312 x 182UB and each batch of beams was ordered in a specific sequence to suit the construction programme.
