Most people know the
difference between stainless steel and galvanised steel, but some of those
differences can be harder to spot with cables. In this article, we’ll explore
the differences between stainless and galvanised cables and how to tell which
type of cable you're dealing with.
These cables are made
from stainless steel, an alloy of iron containing at least 10.5% chromium. This
alloy creates a protective layer on the surface that prevents rust and
corrosion. Stainless steel wire rope provides excellent strength and durability
and can be used in many applications where other metals would not stand up to
the elements or wear quickly.
Galvanised steel has
been hot-dipped in a zinc coating to reduce rust and corrosion, albeit less
effectively than stainless steel. Galvanised steel cables are often used for
less demanding applications, such as building construction or outdoor projects
like fences or playgrounds. In contrast, stainless steel wire rope is more
expensive but lasts longer under harsh environmental conditions.
So how can you tell if a cable is stainless or galvanised?
While both types of
steel have a similar appearance, it can be difficult to tell them apart just by
looking. However, there are several approaches to determining the two:
to scratch the surface of the cable with a sharp object; stainless steel will
have a smooth, shiny finish, whereas galvanised steel will be rougher to the
way to determine the cable type is to use a magnet. If the cable is made from
galvanised steel, it will be attracted to the magnet. Stainless steel is
non-magnetic and will not be affected by magnets.
Most stainless cables will be silver, while galvanised cables will be dull
Stainless steel is heavier than galvanised, so if the cable feels unusually
light, it could indicate it is galvanised.
Visible signs of corrosion:
Another approach is to check for corrosion spots or rust
on the cable, indicating that it is galvanised and not stainless. Be sure to
look closely, as galvanised steel may still have a shiny appearance even when
factors, you should be able to tell whether a cable is stainless or galvanised
with some degree of accuracy. It's important to remember that different types
of cables have different properties, so it's essential to understand the
differences in order to make an informed decision about which type of cable is
best suited to your project.
