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 120metres.
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 3 kPa 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.
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 S5 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,

concealed fix profiles (Saflock 700 for wider sheet
coverage, and Saflok 410 with extra lock down

Safintra also manufactures the Versatile™
profile, which combines the structural benefits
of a continuous steel sheet with the aesthetic
appeal of a tile.
Their products are renowned for their
strength and modern visual aesthetic by archi-
tects, quantity surveyors, specifiers and interior

The complete roofing solution includes
accessories, flashings and closures, Fixtite
fasteners and S5 clamps, which are suitable
for most panel and fixture attachment onto
roofs. Cleardek multi-wall polycarbonate sheet
