BlueScope Steel Limited is an Australian flat product steel producer that was spun-off from BHP Billiton in 2002 and it’s brand Colorbond is recognised as a leader in roofing supply industry. The Sydney based client with Colorbond roof towards the East-North side was using AC indoor unit virtually 24/7 during Australian summer time. After brief preparations and cleaning our applicators have applied a thin layer of about 0.5-0.6mm of C-COAT producing an immediate reduction of about 20oC in surface temperature and accordingly reducing a need for AC totally. We followed up with this client to find that they experienced huge reduction in electricity bill and significant improvement in indoor conditions.
