Is
hot
dipped
galvanized
better?
The
thicker
zinc
coating
produced
by
hot
dip
galvanization
offers
improved
rust
and
corrosion
protection
versus
pre-galvanization. This is an important quality in a temporary fence panel, as it is most often used outdoors and
exposed to snow, ice, rain, and salt.
How
long
do
galvanised
roofing
sheets
last?
Metal
roofing
sheets
have
a
considerably
long
lifespan
and,
although
manufacturers
will
often
state
an
expected
lifespan of 10 – 15 years, people more than often find that they last much, much, longer with some people reporting
their sheets to still be in good working order after 60 years!
What
is
purpose
of
zinc
coating
on
GI
sheet?
Because
of
the
sacrificial
nature
of
the
zinc,
the
coating
provides
corrosion
protection
for
areas
of
exposed
steel
surfaces, such as cutting edges and areas where coating has damaged (scratches, impacts, etc.).
