EXTENDING THE LIFE OF STEEL
WITH DUPLEX COATINGS
The importance of steel in most architectural projects cannot
be underestimated. From bridges to stadiums, high-rises to
houses, steel acts as a durable, flexible, environmentally
friendly, cost effective material. To preserve its longevity and
aesthetic appearance however, it needs to be protected from
the elements to prevent rust and corrosion. One of the most
effective and long-lasting ways to protect steel and enhance its
aesthetic appeal, is by treating it with a duplex coating.
What is a duplex coating?
A duplex coating is a synergy of hot dip galvanising and powder
coating suitable for all types of steel architectural projects,
including structural sections, gates, railings, staircases, lighting
and flooring.
Used independently, a galvanised coating and a powder coat
provides a good level of protection for steel. However, as steel
begins to age, the galvanised zinc coating erodes, making the
steel more susceptible to weather damage. If the steel has
also been painted or powder coated however, it acts as an
extra barrier, which slows down the zinc erosion rate. This is
the main advantage of a duplex coating: when used together
the synergistic effect of the combined coatings provide a far
superior level of protection to extend the life of steel.
Duplex coatings benefits:
1. Durability
2. Ease of repainting
3. Economical
4. Aesthetics
5. Sustainable
6. Environmentally friendly.
