1. Aluminium
1.1. What are the advantages of an aluminium vehicles?
1.2. Is there an additional cost for an aluminium vehicle?
Yes, aluminium vehicles are slightly
more expensive than equivalent
steel designs. If we analyse the difference
in detail, we can see that,
when heavy goods are transported,
the additional investment
is paid back after less than two
years. Make your own calculations
on www.alutransport.org.
1.3. What are the main benefits for the environment?
Aluminium contributes to the
reduction of CO2 emissions from
road transport as follows:
• When carrying heavy goods,
it increases the load capacity of
vehicles and therefore improves
transport performance, allowing
more goods to be carried per
trip. In this case, one ton saved
on the dead weight of an articulated
truck saves 1,500 litres of
diesel fuel over 100,000 km.
• When carrying voluminous
goods, it reduces the overall
weight, lowering fuel consumption
per kilometre. In this case,
one ton saved on the dead
weight of an articulated truck
saves 600 litres of diesel fuel
over 100,000 km.
Taking primary production, use
stage and end-of-life recycling
into account, life-cycle savings
have been estimated1 that 1kg
of aluminium in today’s average
articulated truck saves
28kg of CO2.
Truck fleet operators benefit
from a better performance of
their fleet.
There is a significant payload
increase which makes the fleet
much more profitable. Another
fact is cost savings that result
from smaller fleets with less
staff, lower fuel bills and lower
road toll costs.
Trailer rental companies can offer
operators semi-trailers with a better
performance. Due to the
higher payload, the longer life
and the higher residual value of
the equipment these companies
can generate more profit by
using state-of-the-art equipment.

No, it is not. Aluminium with its
natural «alumina» layer has an
excellent protection performance.
If an operator chooses to
pay extra money (and weight
too!) for the paint finish, the
motivation to do so lies in having
a fleet with a particular
branding.
1.4. Is it necessary to paint an aluminium vehicle?
1.5. Is it possible to repair an aluminium vehicle?
It is often said that aluminium
vehicles cannot be repaired,
however this is totally wrong.
Few people know that Land
Rover cars have had an aluminium
body since the end of
world war two, and in the last
50 years nobody has ever complained
about repair problems.
This illustrates the fact that
repair is possible as for any
other materials, but aluminium
repair techniques are definitely
different from those of steel.
Please refer to the Chapter XIV
for detailed information.
Leading chassis manufacturers
have set up a European dealer
network where an efficient
repair service is offered.
1.6. Does aluminium burn?
NO, aluminium and its alloys
are, under atmospheric conditions,
totally non-combustible
and do not contribute to the
spread of fire.
Aluminium alloys will however
melt at around 650°C, but without
releasing harmful gases.
