Last but not least, extra safety
features always mean additional
weight, which can be balanced
by replacing heavy materials by
aluminium.

EUROPEAN ALUMINIUM ASSOCIATION
Unlike traditional vehicles that
are exported to end their life a
long way from Europe, aluminium-
intensive trailers generally
spend their entire life in our
continent, where they are eventually
dismantled5. Due to the
high value of aluminium scrap,
the motivation to sell to a scrap
merchant is very high and landfilling
is avoided.
Recycled aluminium does not
loose any of its quality and saves
95% of the primary production
energy input. The energy
required to produce primary aluminium
is not lost: it is “stored in
the metal”.

4.1. Looking good forever
The modern commercial vehicle
cannot escape the pressures of
industrial design. Operators want
their vehicles to look good with
clean, pleasing lines, something
which aluminium alloy semis are
ideal for producing.
For example, using functional
extrusions and plain or prepainted
aluminium sheet that is
easy to shape, it is a straightforward
matter to produce vans
with rounded body corners both
inside and out.
With tippers and self-discharging
bodies, this makes for a smooth
unloading and easier cleaning. In
addition, using double wall aluminium
extruded boards allows
the preservation of a perfect
exterior surface over the time.
Image conscious operators appreciate
this type of construction very
much.
Aluminium is used to produce
the lightest, the strongest and
the most beautiful wheels.
Last but not least, no corrosion
will appear after impact on aluminium
parts, therefore preserving
the image of the company.

4.2. Aluminium is easy
to repair
Few people know that Land
Rovers have had aluminium closure
panels since 1948, and in
the last 50 years, nobody has
ever complained about repair
problems. This illustrates the fact
that repair is possible, but aluminium
repair techniques are
definitely different from those of
steel. Leading chassis manufacturers
have set up a European
dealer network where an efficient
repair service is offered.
