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® and COLORBOND®,
have taught the industry many valuable lessons. One
such lesson is that stainless steel fasteners have been
shown to be incompatible with COLORBOND® 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.
