Hot Dip Galvanisation - AL-KO CARAVAN CHASSIS Handbook

AL-KO CARAVAN CHASSIS

HOT DIP GALVANISATION

The chassis is Hot Dipped Galvanised. This is regarded as one
of the best forms of corrosion protection. It does however
require minimal maintenance in certain circumstances.
When new, the chassis is of a bright and shiny appearance.
As the galvanising cures during the initial 2/ 3 month
period, this will gradually change to a medium/dark grey
colour. This grey finish is the ideal, giving the correct
protective coating. During this curing period the surface
should be protected to avoid possible wet storage stain,
in the form of a soft, light coloured, porous, oxidation
layer. If the chassis members are in contact with any salt
deposits from roads this should immediately be washed off
with a high pressure washer. Salt attracts moisture allowing
the surfaces to remain wet, this prevents curing and also
allows formation of wet storage stain.
It is recommended that the chassis/ components are washed
off, using a pressure washer on an annual basis (especially
after winter usage), to avoid undesirable build up of salt and
dirt deposits.
The galvanised chassis should not be painted or subjected to any
other protective treatment.
Should the galvanising become superficially damaged exposing
the steel core, this should be cleaned and treated with a Cold
Galvanising Spray obtainable from vehicle accessory outlets.
Damage to chassis members through impact etc, MUST NOT
be straightened or welded. Damaged chassis members MUST
be replaced.
