Under roof corrosion of roofing fasteners is the great
hidden danger. All protective coatings are subject to
damage during installation when crest fixing metal roofing.
Damage is caused by the scratching of the roof sheeting
along the shank of the fastener. This allows the corrosive
environment to attack the exposed metal of the fastener
shank – reducing the structural integrity of any
construction leading to costly repairs and replacement.
ShankGuard® is a revolutionary patented design feature
specifically designed to protect fastener shanks from
scratching and scouring. ShankGuard® cuts a slightly
larger hole in the roofing profile than the shank diameter,
protecting it against scratching on the sharp edges
of the pierced hole in the metal roof. By remaining
scratch free the fastener shank keeps its corrosion
coating intact and fully functioning, up to 60% more
corrosion resistant in comparative tests carried out
in accordance with AS3566.
