Exceptional wind uplift strength
Saflok and Newlok (unseamed) are both concealed fix or secret fix profiles as the anchoring system is not visible, providing unrestrained thermal expansion or contraction. The difference between concealed fix and standing seam (Newlok) is that the Newlok profile can be seamed, either mechanically or by hand, giving it additional wind uplift strength.
NEWLOK is a concealed fix, standing seam sheet profile with an effective cover width of 445mm, and a height of 50.8mm.
Saflok 700 is a concealed fix profile, with an angular interlocking standing seam trapezoidal rib profile roll formed on mobile mills countrywide.
