Company Announcement - Safintra South Africa announced the launch of the Newlok standing seam range of concealed fix roofing. Standing Seam is a category of profiled metal sheeting where the side laps are mechanically seamed for extra lock-down onto concealed fastening mechanism.  It is part of a broader category called CONCEALED FIX roofing, in which a concealed fixing device is used to secure the sheet from under the side lap, thus avoiding the need to pierce the sheet to secure it.

The Newlok mobile mill, which can be transported on-site, rolls the steel forms for the profile in continuous lengths of up to 120 meters. Benefits of Newlok include:

• The system is suitable for use on extremely low-pitched roofs
• Unique profile offering either a snap-together interlock, or a snap-and-seam locking mechanism for optimum wind stability
• Exceptional hold down strength in excess of 3kPa on negative wind uplift on the seamed profile.
• Interlocking system allows natural thermal expansion and contraction, without unclipping between purlin supports
• Wide purlin supports for economical design
• Concealed fasteners provide increased security, as roof sheets cannot easily be removed from the outside

Metal roofing is making a comeback in house design for its environmental credentials (100% recyclable) and practical values as it is long wearing, unique and low maintenance - and for aesthetic value. Safintra. When seamed, the standing “rib” provides the perfect attachment substrate for above roof installations such as solar PV panels, HVAC units, piping and more, without violating thermal expansion and contraction of the roof.  Top quality clamps, such as the S-5 range, may be attached to the ribs without penetrating the roof sheet, thus preserving metal material warranties as well as installation warranties on water-tightness. Safintra’s range of roofing products include both pierced (Widek™, Trimflute™, Fluteline, Classicor Corrugated and Tufdek IBR), and concealed fix profiles (Saflock 700 for wider sheet coverage, and Saflok 410 with extra lock down for challenging wind conditions).
