2010 Soccer World Cup StadiaSOCCER CITY20 Hot Dip Galvanizing Today Volume 7 Issue 1 2010
2010 Soccer World Cup StadiaInnovative use of Mentis grating atSoccer CityTypically used in horizontal industrial and mining flooringapplications, Gripweld grating is being used as part of the‘Pit of Fire’ at Soccer City Stadium, south of Johannesburg.What makes this application so unusual is that the gratingwill be placed within a framework, produced by SpiralEngineering, in a vertical orientation. Some 1 100 runningmetres of B-100 Gripweld grating has been supplied byAndrew Mentis to Spiral Engineering.The design of the stadium is based on the calabash orAfrican pot which is constructed on a raised podium,referred to as the ‘pit of fire’, to lend the impression of thepot being fired. The ‘fiery pit’ demarcates the security andturnstiles line, separating the outer areas and the secureinner areas.“As a result of our reputation of producing architecturallypleasing, functional objects, we were selected byconstruction contractor Grinaker-LTA to design andmanufacture a hot dip galvanized framework that wouldhave both aesthetic appeal and uncompromising strength,”Les Steel-Smith, director at Spiral Engineering, says.Gripweld product was made that much easier by workingwith a reputable supplier,” Steel-Smith adds.The grating was selected over traditional fencing materialbecause of its integral strength and inflexibility. Steel-Smith points out that in order to eliminate unauthorisedremoval of panels, Spiral Engineering has used 5 000tamper-proof bolts and sheer nuts to secure the Gripweldpanels into the framework.“Probably our biggest obstacle is that each panel was adifferent size so we needed to first produce a mock-up ofour requirements, then get Andrew Mentis to produce exactsizing for the 260 double gates and 180 single gates,” Steel-Smith says.The contract was awarded at the end of 2008, with supplyof the panels having commenced in February and thecomplete project delivered by Spiral Engineering at the endof 2009.“In essence, the framework with incorporated grating, formsan architectural column, complete with a roof and entailsclipping the panels into rectangular tubular frameworkengineered and manufactured by ourselves and hot dipgalvanized locally,” Steel-Smith explains.“The Andrew Mentis B-100 Gripweld was specified by thecontractor. We have built up a very close workingrelationship with Andrew Mentis over the years so thesuccessful incorporation of our conceptualisation and thePROPOSED FEATURES FOR 2010May/June (No 43):• Tubes, pipes and scaffolding• Masts and poles• Water storage• Heat exchangers and cooling fansAugust/September (No 44):• Awards• Cable ladders and traysNovember/December (No 45):• The world of hot dip galvanizing around us• Sustainability of the industryNOTE: FEATURES MAY BE SUBJECT TO CHANGEVolume 7 Issue 1 2010 Hot Dip Galvanizing Today 21
