SYSTEM IS DESIGNED & PATENTED BY
ESRO (ERALUER SICHERHEITSOLLADEN GMBH)
With normal shutters, unauthorised
persons can gain access into buildings by forcefully
lifting the shutters up to half a metre and sending
a person underneath to activate the controls internally.
ESRO self-locking security roller shutters, blinds
and grilles were developed as the result of research
done by ESRO, Germany to combat this problem of
unauthorised access.
UNIQUE
SELF-LOCKING SYSTEM
With ESRO's self locking security
shutters, each profile locks within the guide rail
once the shutter is fully suspended and a special
mounting technique eradicates the possibility of an
authorised opening of the blind. No external locks
are required. The security blinds have a European
Security Rating of ER4; which is just one level below
the rating for safes.
Some salient
features of these products are as follows:
HIGH
STABILITY
The products are made of extruded aluminium alloy AIMgSi
0.5 F 22/25. The design of the profiles, coupled with
the weight and strength of the product makes it highly
resistant to wind pressure and any attempt to pull it
out of the guide rail.
WIDE
WIDTH
ESRO's profiles are specially designed and extruded
with precision to acheive high stability and as a result
ESRO's shutters and grilles are able to span up to 12
metres in width without a central mullion and with no
sagging.
SMALL WINDING PACK
The design of the profiles allows for a very smal
winding pack so that installation into most spaces
is possible including behind shop windows and existing
buildings where headroom is limited.
LOW
NOISE
Metal to metal contact
is minimised in the design of the curtain system with
the incorporation of PVC strips in the guide rails.
The shutters and grilles are certified as low noise
shutters and are permitted to be used even in residential
areas in Germany.
As aesthetic apperance,
coupled with low maintenance, ESRO shutters and grilles
make an excellent choice.
VARIOUS
DESIGN
The blinds and shutters can be single or double walled.
For the grilles, the grille pieces can be in LM72 (55
mm pitch) or LM82 (80 mm pitch) and of varying widths
to the customers desire.
Double wall profiles can be filled with insulation for
heat and noise protection or reinforced with steel sheets
for extra safety.
Shutters and
grilles can be integrated and as the profiles are designed
to fit together, no scratching occurs while in the process
of winding up or down.
