Lightweight steel roofing system an ideal fit for new Uitenhage development

Turnkey construction company Lamprecht Properties has finished the construction of the new R120-million shopping centre in KwaNobuhle, just outside Uitenhage. KwaNobuhle is home to over 350 000 people and the 15,500 m² retail development will feature 47 retail shops, a 3 000 m² Shoprite and parking for over 550 cars.

Lamprecht Properties approached MiTek to manufacture roof trusses for the shopping mall. The MiTek SA contractors in Port Elizabeth, USM Building Supplies, manufactured, assembled and erected an 18 500 m² roof made from lightweight steel profiles for the project.

“The project which commenced on the 1st September 2009 was successfully completed by the 25th June 2010. This newly constructed roof cost approximately R12 025 000,” says Tony Ward, branch manager of USM Building Supplies. Ken Wright, manager at the MiTek Port Elizabeth branch, explains that MiTek’s Ultra-span Light Gauge Steel Truss System was used and it is an ideal fit for the project. “The Ultra-span system is a light steel gauge roofing system which is used for both commercial developments, such as the shopping centre in KwaNobuhle, as well as in domestic applications,” says Wright.

“Its light weight enables the roofing system to be erected easily on site and the system is also set up in a very short time,” adds Wright.

The biggest advantage of the Ultra-span system is the unique member profile shape that MiTek has developed. Purposely designed with less steel per metre than other systems, the Ultra-span truss shape is fabricated with only three components (chords, webs and a single size connector).

Advantages of the lightweight steel roofing system

  • Elegant simple system, with all members straight and true for a level roof.
  • Span capability from small low-cost to large 40m clear span commercial structures.
  • Longevity of product due to galvanized coating plus inherent properties of non-combustibility, resistance to borer and fungus attack.
  • Lower weight reduces transportation costs, improves handling and erection.
  • Ease of truss manufacture with screws and electric fixing tool directly on site or in factory conditions.

Wessie van der Westhuizen, a manager at Lamprecht Properties and site-manager for the shopping centre in KwaNobuhle, says that they have been using the Ultra-span system for a number of years and are satisfied with the product. “We were the first people to install the Ultra-span roofing system in the Eastern Cape. Lamprecht Properties has been using the lightweight steel roof systems for three years and we will keep using it due to its ability to save a huge amount of time on a project,” says Van der Westhuizen.

“USM Building Supplies are able to design the roof, and the entire roofing system arrives in a container on site where you simply assemble it and lift it onto a structure with a crane. It is completely hassle free,” says Van der Westhuizen.

Ultra-span trusses can also be supplied in ‘kit-form’ for low-cost housing or other remote projects, whereby trusses are assembled on site or in pre-fabricated form ready for installation on the roof.

“Ultra-span has a variety of benefits. If your roof is too large to be done in pre-fabricated timber or you are shipping roofs into Africa and spending a lot on transport, for example, this roofing system is a great non-combustible roof solution,” says Wright.

The design of the Ultra-span truss system shape allows it to rest flat in the jigging fixture with all of the connection surfaces easily accessible and flush for a quality screwed connection. The system also features gauge connectors for faster screw throughput, same gauge top and bottom chord designs to minimise cutting and handling, and a true truss shape every time including scissor trusses and tray ceiling with no job site modifications.

MiTek Industries S.A. (Pty) Ltd has an international reputation of being a leading roof system supplier in the world. It has licensed over 140 timber truss manufacturers in Southern Africa and uses the Gang-Nail and Hydro-Nail truss systems which are recognised amongst the world’s best. Not only does MiTek have unique capabilities when it comes to professional structural engineering services, but also the company’s continual Research and Development of lightweight steel roof design makes MiTek a significant contributor to the roofing industry.

MiTek would like to congratulate USM Building Materials (part of the Iliad Group), for the professional way they handled the KwaNobuhle Project.
