Material and surface
Stainless steel is extremely suited for ap-
plications with requirements for high wear
resistance, excellent hygiene and good cor-
rosion resistance.
Stainless steel forms a thin, protective sur-
face oxide film which provides for a dense,
durable surface with high mechanical load
resistance.
Despite containing e.g. nickel, stainless steel
is considered to be a non-allergenic material
when used for door handles, fittings etc. A
number of sub-components may be made
from other materials, such as polymer, brass
or aluminium, all of which have been used
with due consideration to the optimum
function, manufacture and durability of the
product.
Cleaning and maintenance
Regularly check the function and mounting
of fittings, retighten any loose fixings and
clean product surfaces. In areas and environ-
ments with elevated impact from sulphur
and nitrogen oxides, and in coastal environ-
ments with chloride condensation, the pro-
tective oxide layer on stainless steel may
corrode, oxidising the surface and possibly
forming reddish brown stains that resemble
rust formations. However, this corrosion is
only superficial.
The discolorations can easily be prevented or
removed through normal surface cleaning.
Use hot water, mild detergent, soft brushes
or synthetic sponges for cleaning. In special
cases, you may use custom-made polish for
stainless steel. Never use scouring pads,
steel sponges or steel brushes as these may
damage the surface!
The product is only covered by warranty if
correctly mounted and maintained.
Environment
If used alone, stainless steel emits no haza-
rdous vapours or metals. Generally, stainless
steel is not classified as environmentally
dangerous waste, but because the material
contains heavy metals, the products must
be disposed of according to the regulations
for industrial iron/metal waste, which ensu-
res optimum sorting and recirculation.
Specific lubrication instructions
Side hung hinges
Hinges on side hung windows
and doors should be lubricated
with acid-free oil during repeated activation.
We recommend lubrication with acid-free
grease. It will, however, be necessary to lift
the sash off the tenons and apply the grease
directly onto the tenons.
Top guided, side
swing reversible and
side hung
These are all hinge systems, and all joints
must be lubricated during repeated activa-
tion so that the lubricant reaches the mo-
veable arms. The joints should be lubricated
on the outside and in the crack between the
arms. Use an easily penetrating acid-free oil
followed by a long-lasting acid-free grease in
spray form.
Sliding surfaces, hinge sliders and sliding
blocks should be maintained in a clean state
to facilitate sliding.
