What is concealed fix sheeting and what makes it unique?

The concealed-fix Roofing system was developed to accommodate the effect of thermal expansion and contraction of Roofing Sheets under extremes of temperature and to provide a watertight low pitch roof in heavy tropical storms. It is a modern development of the “Standing Seam” roofing used successfully throughout the world for generations. The Concealed-fix system has been on the South African market since 1964. Over the years it has earned an excellent reputation and enjoys a high acceptance amongst Architects, Quantity Surveyors, Engineers and Contractors.

The concealed-fix system, Klip-Tite™ the latest development in 2013, is the most highly specified proprietary roof system presently available in South Africa. ​
IT HAS VERSATILITY The upstanding ribs and flat base of the profile provide opportunities for a variety of architectural treatments. The profile is strong due to the depth and rigidity of the ribs. Klip-Tite™ and Klip-Lok™ are offered in several conventional and other materials to meet the various requirements of long life, aesthetic appeal and resistance to environmental corrosion. ​ EASE OF ERECTION The system of fixing the Klip-Tite™ and Klip-Lok™ roof sheets to the roof structure utilizing concealed clips is relatively uncomplicated provided that the laid down erection procedures of the KL700 Plus clip are followed. ​ ​
IT IS LEAKPROOF, WEATHERTIGHT AND STRONG The concealed clip system of fixing means that the sheet is not holed by main fixings. The deep vertical ribs and 233mm broad pans increase water-carrying capacity and rapid run-off. The profile geometry is such that deflection under load is reduced allowing flat pitches. No end laps are required. ​ ​ IT IS ECONOMICAL The Klip-Tite™ and Klip-Lok™ sheet’s greater water capacity and concealed fixing system (no holes through sheeting) allow the sheet to be used on very flat pitched roofs, thereby reducing roof structure costs to a point where it becomes the most economical roofing system on the market.
