We at Metroll Newcastle offer an extensive range of unique, innovative
fastener solutions for metal, wood, concrete and masonry applications.
These superior quality fasteners are designed for a variety of uses
including premium metal roof and wall applications.
Fasteners are manufactured in a wide range of materials from common
steel to titanium, plastic and other exotic materials. The fastener
material determines the strength, brittleness, corrosion resistance,
galvanic corrosion properties, and cost. These fasteners come in
different material grade and a variety of coatings to enhance the
corrosion resistance and/or their appearance.
Designed specifically for premium metal roof and wall applications,
our fasteners comply with standard AS 3566 that requires minimum
corrosion resistance levels under accelerated testing of 1000 hours,
salt spray testing, 15 cycles acid rain testing, 2000 hours testing
for organic coatings and 1000 hours humidity testing.
The testing of new types of coatings and fasteners, which have appeared
since the introduction of AS 3566 in conjunction with ZINCALUME® steel and COLORBOND® steel, have taught the industry many valuable lessons.
One such lesson is that stainless steel fasteners have been shown
to be incompatible with COLORBOND® steel and cause premature corrosion
of roofing sheets.
Our helpful staff can help you access the most appropriate fastener
application to match the performance of fasteners to the metal cladding
or roofing, as well as having compatible life with the cladding or
roofing. We specify that fasteners must at least meet AS 3566 Class
3 if the basic objective of having fastener and cladding compatible
life spans is to be met.
