Product Review You’ll never need a brick pier again... ...now there’s something much, much better! Above: PosiTrusses lend themselves to curved designs and greater spans. Although PosiTrusses have been used more commonly in the construction of floors, Robert says the qualities of the trusses has also led them to be used in numerous innovative roof designs, with their lightweight quality also making them much easier and cost effective to work with. And being relatively lightweight means a reduction in the weight of the overall structure, and consequently savings in foundations and framing which would otherwise need to be especially engineered for heavier structures. The trusses can be used to create anything from standard roof lines to curved structures and are of particular use where height restrictions are an issue, and – as with flooring applications – PosiTrusses can achieve greater spans with fewer load-bearing walls for larger open areas and increased design possibilities. Using PosiTrusses for second-storey homes, steep sites, and sites with poor foundations which need to be cut-and-filled will also reduce the costs associated with retaining wall structures. All-steel Uni-Pier is replacing brick piers, concrete and timber stumps. It’s the superior piering system: easier, faster, simpler. • Sized to suit: 200mm to 5000mm in increments of 200mm • On-the-job head adjustment up to 200mm • Easy accurate levelling to within millimetres • Durable with hot dipped galvanised fi nish • Superior “hold-down” strength (windy areas) • Integrated ant caps • Fully engineered design • Domestic or commercial grades • Choice of alternative head designs • Ideal for level or sloping s ites Phone: (02) 9737 9275 PO Box 6484 Silverwater NSW 1811 The trusses can be used to create anything from standard roof lines to curved structures and are of particular use where height restrictions are an issue The three trusses available in MiTek’s PosiStrut’s range are PosiTruss, PosiJoist and PosiPlus. • PosiTrusses are standard, all-purpose trusses suitable for many building applications and made to an exact length where long span joists or rafters are required.
