Steel Frame Construction
All the structural steelwork should be galvanised to prolong the life of the car park and to lower the maintenance cost. Pre-fabrication of steel parts reduces construction time of the parking structure.
The light steel frame should have columns at about 15.6m+ spacing to avoid any columns where the cars turn into car parking bays. 4.8m + 6m + 4.8m = 15.6m. The steel frames are normally at 7.2m centres giving 2.4m wide car parking bays, or at 7.5m giving 3 × 2.5m bays.
With clear span steel framed car parks these standard dimensions work well, but bigger car parking bays are available for US parking lots where automobile sizes are slightly larger.
