According to Dave Reid, the National Product Specialist: Novotexi 440 at Macsteel:
“Sky-Forming is unique to South Africa and Macsteel Novotexi 440 concealed fix roofing. This process of roll-forming roof sheeting in long lengths is becoming the preferred method in constructing mega-warehousing. It dramatically improves the quality of the end product and has advantages on the critical path planning of the project as a whole in allowing following trades to simultaneously operate without blocking the ground space around the site.”
“At roughly 700 meters long and 230 meters wide, the shear size of the facility has been a design challenge from conception. From finding an appropriate-shaped and sized piece of land, to the height of the structure, through to the details of fire escape routes across 230 meters of warehouse floorplate” explains Heyes.
The design has been carefully thought out from a risk-to-business angle, also.
“Mitigating risk from a business point of view meant dividing the drygoods and perishables warehouses with a fire wall. What became aptly known as ‘the-great-wall-of-PnP’ amongst the professional team, is a 200m long and 26m high tilt-up-concrete 2-hour fire wall. Concrete for the pre-cast walling panels was poured horizontally, on sacrificial beds, down at ground level and then lifted with cranes into position to form the central spine of the development” he adds.
Safal Steel’s pre-painted metal roofing coated steel, ColorplusⓇ, is derived from the technically advanced ZincalⓇ substrate, made under licenced technology from BIEC International Inc. The process of manufacture is unique and efficient, during which rolled steel is continuously hot dipped into an alloy mixture. This consists of a 55% aluminium, 44.5% zinc and 1.5% silicon blend. This coating process gives rise to what is best known as AZ coated steel material, not to be mistaken for or confused with ‘Z’ or galvanised roofing material. The AZ material offers significant performance and also environmental sustainability benefits when compared with its heavier and faster- corroding galvanised alternative.
As the pre-painted version, ColorplusⓇ, is coated with a specially formulated paint system that is available in a standard range of 11 colours. Bespoke colours and paint system options are available on request, subject to terms and conditions.
The innovative pigments used in the paint have been carefully selected for colour retention in the long run and keep their a fresh appearance for many years. This technology also limits chalking. With an increasing load of wind-borne contaminants and dust in many environments, particle resistance is also a key feature we build into our paint system. This means that the advanced modified polyesters in the paint system resists dirt, ensuring your roof stays cleaner, retaining its colour for longer.
