[Pretoria, 7 March 2016]: LCP Roofing, leaders in roof truss technology, recently played host to an interactive information session on Newlok, Safintra’s latest concealed fix roofing product. The well-attended event saw LCP Roofing customers, suppliers and staff alike come together for an afternoon of learning and connecting.
When Safintra approached LCP Roofing management about hosting an information session for their staff on Newlok, a product specifically designed for use on low pitched roofs and to withstand high winds, they saw an opportunity not only to learn more about the product in-house, but to extend this to their clients and suppliers as well. “It’s important to us that our clients know about new products on the market and that they understand how these can benefit their projects,” comments Lyndsay Cotton, LCP Roofing General Manager, “Which was why we thought it was a great idea to open this session to our valued clients and suppliers, so that they could really experience the product and engage directly with the manufacturer.”
Safintra took a holistic approach to the information session and brought along their Newlok mobile mill, steel coil, mechanical seamer and 90˚ hand crimper, to showcase the production process of the Newlok sheeting – from roll forming the profile from coil to installation.
Mark Farrell, Safintra’s Johannesburg Branch Manager, demonstrated the roll-forming process using the Newlok mobile mill to produce the sheeting, pointing to its unique profile and clipping system. One of the characteristics that differentiate the Newlok profile is that it can be interlocked either with a snap or snap-and-seam mechanism. When either snapped together or snapped and seamed, the two-part clip allows natural thermal expansion and contraction without unclipping between purlin supports. This makes Newlok a profile that qualifies as both a concealed fix (hidden anchoring system) when snapped together and a standing seam profile (snapped and seamed – either by hand crimping or mechanically), both methods allowing for thermal movement. However, the standing seam configuration provides hold-down strength in excess of 3kPa on negative wind uplift.
While Newlok is ideal for long spans on commercial and industrial buildings, due to the system’s ability to expand and contract as temperatures fluctuate, it also finds application in residential settings. It is specifically designed for low-pitched roofs, is fastened on the underside of the sheeting with clips and not pierced with traditional fasteners, resulting in completely watertight sheeting, even at very low slopes. The 50mm rib height also makes for optimal water shedding capabilities at slopes as low as 1.5 degrees.
LCP Roofing provided a sample roof structure onto which the newly rolled Newlok sheets were fastened by the LCP Roofing sheeting team, led by Edward Chego and Thabo Tjale. “The sample roof provided an interactive and tactile experience for our guests, who could experience the roof structure close to the ground and get up close and personal with the sheeting and clip system,” says Cotton, adding, “The fixing of the sheets was a prime showcase of the Newlok profile in action. Guests could see how the male-female joints easily snapped into place and how the clips held everything together for a smooth, sturdy surface with no piercings. Safintra also demonstrated their hand crimper, for seaming eave and ridge sheets, as well as their mechanical seamer, which is ideal for seaming the entire length of the sheet.”
The Safintra information session highlighted a number of practical scenarios and raised awareness of the unique roofing requirements presented by the South African landscape. “Concealed fix roof sheeting has become a firm favourite among specifiers, but has, until now, not been well suited to the high wind environments experienced in exposed, newly developed areas,” says Andri Pretorius, LCP Roofing Operational Director. “Presently, most concealed fix offerings readily available inland are 700mm wide and, due to changing climatic conditions, need to be positively fixed on both apices and eaves, thereby negating the primary advantage and purpose of concealed fix roof sheeting. Typical residential applications make 700mm wide sheeting problematic to fix and finish off neatly as well. Fitting a 445mm wide sheet on a complex residential roof will also be easier from a labour perspective,” he adds.
Not only is steel roofing cost effective, but it also contributes to the overall sustainability of a structure, as metal roofing can be 100% recycled at the end of its useful life. Coupling a profile like Newlok with LCP Roofing’s offering enables both to better control quality, offer holistic ‘top of wall’ solutions and encourages the roofing system and other retrofits to be planned and viewed as a single investment by industry, instead of as separate components.
“Newlok is a truly innovative addition to Safintra’s roof sheeting range, and in turn, to ours at LCP Roofing. As keen advocates for innovation, we are proud to offer our valued customers the multitude of benefits that come with the Newlok system,” remarks Pretorius, concluding, “A fact that goes a long way in cementing our reputation as leaders in roof truss technology.”
