BUILDING MATERIALS ADVERTORIAL The low mass per m2 (between 2-10kg/m2) of this roofing system ensures both savings on the supporting structure as well as on transportation and erection costs. With additional benefits such as non-combustible, corrosion resistant, straightness of members and ease of assembly – makes this one of the most viable roof systems especially in Africa where good structural wood is not always avalable. Residential (trusses): With savings on trusses due to larger spacing’s added to further savings on erection due to light weight (approx. 4kg/m2) and the convenience of no site wastage makes these roof structures ideal for low-cost housing projects with Tiled or Sheeted roofs. The roof trusses are supplied pre-assembled or in Kit-form for site assembly. Residential (purlins): The strength and diversity of the Ultra-Span profiles makes it an ideal choice for simple purlin roof applications as often found in low-cost housing. Span capabilities vary from 3m -6m with a very low mass of only 2kg/m2 of roof area. With no site wastage and all materials being galvanized, it is ideal in even remote areas. Community: Even Church projects or other community projects with larger spans (as shown above 28m & 30m spans) for both tiled and sheeted roofs are easily managed with Ultra-Span trusses whilst maintaining the vaulted ceiling effect. Commercial: With a proven track record of many successful applications in large clear spans (Spar-Brighton, Zambezi –Mall), Ultra-Span is one of the most economical roof structure solutions in the range from 16m -35m – this applies especially to lowpitched roofs. 54 HARDWARE AFRICA 2014
