1. Rolling shutters specification in india are a type of door normally used for industrial and
commercial. the specification of rolling shutter shall be as per the requirement of the client.
here i am trying to put general information about rolling shutter and its materials, fixing
methods and other details. the rolling shutter accessories should be as specified and
approved should be suitable for fixing in position as specified i.e. outside or inside; on or below
lintel or between jambs of the opening.
Rolling shutter can be hand operated or gear operated. hand operated shutters are of push
and pull type. gear operated shutters are provided with reduction gear operated by mechanical
device with chain, crank, shaft and handle. the shutter consist of 80 mm wide ms laths 0.7
to1.25 mm thick or gauge as specified of mild steel sheet roll forming. laths are inter-locked
together throughout its entire length and jointed together at the end with end locks. these are
mounted on specially designed pipe shaft.
The guide channels, brackets and lock plate should be of hot rolled steel of thickness not less
than 16 gauge. cast iron castings used for rolling pulley wheels, u-clamps shall
pipes used for the suspension shaft of the rolling should be heavy duty pipe suitable for
mechanical purposes
The springs used in the rolling for counter balancing the rolling shutter should be made either
from high tensile spring steel wire
both the side guides and bottom rails are joint less and of single piece of pressed steel of
minimum 16 gauge thickness. the top cover of shaft, spring etc. should be of the same
materials as that of lath. hood, brackets etc are required to cover the shaft etc. the reduction
gear arrangement operated by the mechanical device should be of the best quality and easy in
operation.

2. Fixing rolling shutter first the brackets are fixed on the lintel/beam or under the lintel/beam as
required with rawl plugs and screws, bolts, washers etc. The shafts along with the spring are
then fixed on the brackets. The lath portion shutters is laid on ground and the side guide
channels are bound with it. The shutter is then placed in position. The side guide channels
are fixed to the wall through the plates welded to the guides. These plates and brackets
should be fixed by means of steel screws, bolts and rawl plugs drilled into the wall.
The plates and screws, bolts shall be concealed in plaster to make their locations invisible.
fixing should be done accurately so that the operation of the rolling shutter is easy and
smooth. the smooth and easy working of roll shutters are ensured. to prevent rusting of
shutters, it is cleaned off dust, scales, rust etc. and priming with a coat of red oxide paint is
done before fixing the rolling shutter in position and then it is painted with two coats of
flat/synthetic enamel paint.
