Saflok 700

Saflok 700 is a concealed fix profile, with an angular interlocking standing seam trapezoidal rib profile roll formed on mobile mills countrywide.



Concealed-fix roofing, also referred to as secret fix, is designed for very low pitched roofs. Because clips under the sheet hold it down, the sheet is not punctured with fasteners, and remains completely watertight even at a very low slope. The securing clips are pre-fixed into the purlins and the sheet is mechanically snapped onto the clip.

As a concealed fix sheet can also expand and contract over the clips as the temperature changes, this system is ideal for long spans on industrial, commercial and retail buildings. The Saflok 700 ® concealed fix roofing system is an interlocking trapezoidal rib profile that can be rolled on site in lengths of up to 120 metres.

Saflok 700® may be rolled in Aluminium – Zinc coated steel, (bare or colour coated) or Aluminium (Mill Finish or G4 Colortech). Saflok 700® can be curved or bullnosed to a minimum internal radius of 450mm – 500mm. Reverse cranking is not possible.
