The production and storage capabilities expansion project for a leading brewery in Lusaka, Zambia, received a nomination into both the Pan African Export as well as Industrial/Mining categories of the Steel Awards 2024. The Steel Awards is a programme of the South African Institute of Steel Construction (SAISC). These annual awards recognize outstanding steel construction projects. They celebrate the efforts of engineers, contractors, architects, and project teams. As a proud member of the SAISC, Safintra is proud to have been the steel roofing and cladding to this Pan African project, where SaflokⓇ and IBR profiled ColorplusⓇ AZ150 steel roofing and cladding material was used.
Roll forming took place on site in Lusaka by Safintra Namibia. The selected colour was Safal Steel’s Chalk.
Toit Oosthuizen of JTC Buildings, who presented the project at the Steel Awards 2024, comments: “We designed, supplied and installed around 800t of pre-engineered metal buildings (PEMB) for the Zambian Brewery expansion project and an additional 250t of lattice steelwork for pipe bridges”.
Of significance was the use of steel that was pre-engineered into components for assembly on site as PEMBs.
Oosthuizen says that highlights of the design and construction included the speed afforded to the project by using PEMBs. This material, along with the lightweight benefit offered by the roofing and cladding meant that the buildings could be assembled on site during quiet hours with great efficiency, the roof spans being based on clear spans of 45m. This facilitated large open internal space, free of columns. Such was the good functionality imparted by working with steel.
The overall use of steel
In his presentation to the SAISC, Oosthuizen pointed out to the Steel Awards judges that such a project utilised 1050t of steel, including 800t used on the PEB structures and 250t on pipe bridges that connected the older working buildings on the premises with the new.
25 000m2 of steel roofing and cladding were roll formed to clad the building uniformly in Safal Steel’s ColorplusⓇ Colour Chalk.
Safintra celebrates the usage of its steel roofing and sidewall cladding products in such a Pan-African environment, where we rose to the challenge of roadhauling product through Botswana to Zambia and then roll forming of steel coils of ColorplusⓇ AZ150 on the remote site for the roof cladding.
Project & product highlights:
Project Completed: Feb 2024
Steelwork Completed: Sept 2023
Roofing and cladding completed: Dec 2023
Base material: Safal Steel Colorplus AZ150 TCT 0.53
Colour: Chalk
Profile, roof: Saflok 700
Profile, side cladding: IBR pierced fixed.
About Saflok 700
Safintra 0.50mm thick Saflok 700® interlocking roof sheeting is typically fixed to steel internal purlins at 1900mm centres and ridge/eave purlins at 1700mm centres using Saflok 700® clips which are fastened to steel purlins with Fixtite™ or Safintra approved wafer head self-tapping fasteners, all in accordance with the manufacturer’s recommendation. The steel base substrate is commonly Colorplus® AZ 150, AZ200 or in Zincal (uncoated steel sheet) while the profile can be rolled using the specifiers base material of choice. The sheeting is a double interlocking concealed fix Saflok 700® profile as manufactured by Safintra. Roll-forming is done in continuous lengths from certified G550 steel. The profile shall be roll-formed with 4 ribs and centres not exceeding 233mm and a cover width of 700mm. The male rib is to include spurs to ensure a double interlocking action with adjacent sheets. The minimum rib height will be 41mm. Two stiffening ribs are incorporated in each pan.
