corrosion risk
Area of use «radiation protection doors»
ÖNORM S 5210 regulates the requirements for radiation protection doors. A
specialist lock with two nuts and two cylinder penetrations is used because
of the lead plates that are installed. We can offer our GEOS half fittings
especially for this lock, mounted displaced from one another on the door
leaf and individually on each side. This arrangement of lock and fitting prevents
radiation passing through the door leaf when installed correctly. GEOS
half handle fittings with a counterbracing pin 248 are used, as it is not permitted
to drill or screw through the door leaf. The screws only on the rebate
side are usually a problem (there is often only a wood thickness of 5mm - 6
mm available). For this reason we offer you rosette fittings with a special
screw system against a counterplate with integrated M4 screws. The exact
arrangement of the half handle fittings can be seen in this sketch.
Model 1700 GEOS - Area of use «corrosion risk»
Special requirements for stainless steel
Corrosion risk exists everywhere where the support structure of the fitting
can come into contact with aggressive, corrosive liquids or vapour. In
tunnels, for example the saliferous atmosphere can have an effect on the
fittings and during cleaning of tunnels or slaughterhouses the cleaning
materials can have a destructive effect on the material. Another example
can be found in swimming pools, the chlorine atmosphere which can also
cause damage, as can the use of fittings near the coast.
We can offer the stainless steel fitting model 1700 GEOS in the following
qualities:
→ door handle in accordance with DIN 17 440, material no. 1.4301 (SUS
304, V2A),
→ for plates and/or rosettes material no. 1.4307 (SUS 304, V2A)
e.g. in the finishes E-POL or E-PVD
Further important product specifications in the case of corrosion risk are as
follows:
→ The support structure with connection screws and square pins is
delivered in stainless steel 1.4301 (SUS 304, V2A) in this version.
→ Use of the door handle bearing D6PFH in round roses and D51PFH or
D52PFH for short backplates.
→ square 9 mm spindle

Area of use «construction without obstacles»
Construction without obstacles is regulated in ÖNORM B 1600 and
ÖNORM B 1601. Opening doors is often an obstacle that is difficult to overcome
for people with special needs, children or people with a short-term
handicap (e.g. a broken foot).
This is why we offer fittings for handicapped persons. A specialist WC
solution is also available.
