Steel trusses an economical choice

Choosing the Ultra-Span light gauge steel roof truss system for its new truss plant factory in Polokwane, Martek Roofing achieved significant savings.

For the roof of the new Martek Roofing truss plant factory in Polokwane, the MiTek-licenced truss supplier opted for the Ultra-Span light gauge steel (LGS) roof truss system.

The total roof structure of approximately 584m² mostly comprises of 16m trusses and some 25m clear span trusses, all being of bow-string shape. The light gauge steel weighs about 8kg/m².

According to Uwe Schluter, business development manager at MiTek Industries South Africa, in the case of a relatively low pitch roof, once clear span structures become larger, the Ultra-Span LGS roof trusses become the more economical choice compared to timber trusses.

“In fact, in this particular case the saving was about 10% less compared to a mild steel roof structure. Due to the fact that Martek could also construct the whole roof structure themselves, the true savings were even higher since transport and erection costs were lower. In addition, the lighter mass on the supporting structure allowed for secondary savings on other building costs,” Schluter explains.

“As usual, the trusses were pre-assembled into braced bays on the ground and then lifted into position by crane to connect unto the supporting lattice girders, with the final result being an interesting and different roof structure,” he adds.

Martek Roofing has been a MiTek-licenced timber truss supplier since October 1996. Under the leadership of owner and managing director, Sakkie Maritz, Martek Roofing was also one of the first South African companies to adopt the Ultra-Span LGS roof system with its LGS top-hat purlins, battens and bracing members when MiTek Industries South Africa introduced this roof system locally in 2001.

Like Martek Roofing, Schluter points out that the Ultra-Span (LGS) roof truss system is a preferred solution for quite a few MiTek-licenced truss suppliers.
