The unique combination of aluminum and zinc can outlast galvanized
steel by two to four times, depending on the environment.
Equivalent formability to conventional galvanized products
allows for a wide range of applications.
Aluminum-Zinc Coated Steel's smooth surface is architecturally
pleasing and makes for a superior surface for pre-painting
No primer required when field painting, provided a water based
acrylic finish coat is used.
Aluminum-Zinc Coated Steel is available in pre-painted
Operating conditions resulting in surface temperatures up
to 600 degrees are easily withstood without surface discoloration.
Aluminum-Zinc Coated Steel sheet reflects a high percentage
of heat and light. In roofing, it acts as a shield and thermal
coating over steel consists of an alloy of nominally 55%
aluminum, 1.6% silicon, and the remainder zinc by weight,
as listed in ASTM designation A792.
on long-term atmospheric corrosion test results, it is estimated
that Aluminum-Zinc coated steel sheet will outlast G90 galvanized
by two to four times in marine, industrial and rural atmospheres.
salt spray tests with cut edges exposed, the corrosion resistance
is typically three to four times that of G90 Galvanized.
