Robertson and Steeledale provided engineering, manufacturing and installation of 20,068 square metres of SF1000 Low Profile Ridge Ventilators, 5,500 square metres of HVD 470 Low Profile Ridge Ventilators and 4,028 square metres of Continuous Louvres.

Ventilators and louvres were provided to the Potrooms A & B, Bake Oven, Cast House and all ancillary buildings on site. The ventilator exhaust performance was calculated to meet the specific project conditions. CFD (Computational Fluid Dynamic) modelling was undertaken for the Cast House complex to ensure ventilator sizing and locations were optimised.
