PROJECTS A critical element of the warehouse roof design was the selection of steels. 43.5% zinc and 1.5% silicon. It has excellent corrosion performance, forming capabilities and is available in high strength grades. “The continuous hot dip process used to produce the roofing and cladding substrate provides a surface coating which has a shiny appearance with a uniform small spangle. This coating reduces the solar absorptance of the surface. In short, ZINCALUME minimises the fraction of the sun’s energy absorbed by the roof and maximises the fraction reflected, giving an SRI of 63 that endures for up to four times overall project. A total of 2 500 tons of structural steel was raised to the sky. As far as the roof is concerned, Dave Reid, general manager at Macsteel, concurs. “Significantly, Macsteel roll-formed 660 tons in the Novotexi 440 profile on site with our mobile roll forming machines in a record time.” According to Joubert, construction broke ground on 14 November 2016 and by the end of March 2017, the main 2 180-ton base warehouse structure was completed – an exceptional feat for this prime structure. longer – an exceptional feature for a non- painted roofing steel,” explains Hanekom. Erected by Impact Engineering, the warehouse’s Clean COLORBOND cladding wows in Armour and Volcanic Grey – bold colours used to keyline prominent structural elements on the side of the building in a visually pleasing way.
