CHASSIS
GALVANISED CHASSIS
The chassis is Hot Dipped Galvanised. Hot dip
galvanising has been used for many years
throughout the automotive industry and is
widely regarded as one of the best forms of
corrosion protection.
When the steel is withdrawn from the
galvanising bath it has a clean, bright surface.
Over a period of time this changes to a dull
grey colour as the surface zinc reacts with
oxygen, water and carbon dioxide in the
atmosphere to form a tough, stable, protective
layer.
During this time, if galvanised items are stored
in damp or wet conditions, where there is little
or no air movement, then the zinc will continue
to react with the moisture that is present. In so
doing the zinc will produce excessive amounts
of zinc hydroxide. This is seen as a bulky
white deposit on the surface of the galvanising
and is often referred to as wet storage stain
(white rust).
In the case of Leisure Accommodation
Vehicles, you can help to prevent wet storage
stain (white rust) occurring. You can do this by
washing the chassis with clean water as soon
as they are delivered. You must then allow an
adequate flow of dry air to ensure that they dry
off completely.
Should wet storage stain (white rust) occur on
a product however, then it can sometimes be
removed using a stiff bristle brush or a
“Scotchbrite” pad.
Because of its post process nature “Wet
Storage Stain (white rust)” is not covered
under Warranty procedures.
PAINTED CHASSIS
It is imperative that as a minimum, annual
inspections take place to all painted steel
areas to assess any degradation of the paint
system.
The finish on a caravan chassis is under
constant attack from sunlight, coastal air,
pollution, dust and frost. To this end it is
recommended that the chassis is regularly
inspected and washed as appropriate.
Maintenance may be required at more frequent
intervals because of fading, chalking, chemical
contamination, wear and tear, or for aesthetic
or other reasons.
Mechanical damage to the paint system
will result in a significant reduction in the
paint durability. Hence, mechanical damage
must be identified at an early stage and
appropriate touch-up procedures followed to
the effected areas.
Minor paint damage, such as chipping, can be
touched up with approved paint, available
through your dealership.
CHECKING THE EXTERNAL
STRUCTURE
Inspect visually for damage to panels, gutter
and other external features. Signs of damage,
leakage and movement should be repaired as
necessary.
SAFETY WARNING
ENSURE THAT ALL NECESSARY
WORKING AT HEIGHT SAFETY
PRECAUTIONS ARE IN PLACE BEFORE
CLIMBING ONTO THE ROOF.
WARNING
TO AVOID DAMAGING THE ROOF USE A
15MM OR THICKER SHEET OF
PLYWOOD OR SIMILAR. IT MUST BE
WIDE ENOUGH TO SPAN OVER TWO
ROOF SPARS WHICH ARE
APPROXIMATELY 400MM CENTRES,
A SHEET 1220MM X 1220MM (4’X 4’)
SHOULD BE SUITABLE WHEN
POSITIONED CAREFULLY ON THE ROOF.
