Weather Resistance & Strength Combined
The Shutter allows maximum use within the building because there are no back tracks, as is the case with a sectional overhead door, therefore you can store right up to the doorway with pallets, potato boxes etc.
The twin skin design makes the shutter extremely strong and wind resistant in fact we have installed many shutters throughout the UK that are 12 metres wide by 6 metres high with no wind problems.
The shutters come complete with a bottom rubber seal and brush seals to the guide rails and the soffit thus providing an all round seal and insulation.
The guide rails are fully galvanised as is the curtain area.
The curtain area can be also provided with a Plastisol finish (see the colour chart) or a powder coated finish to the standard RAL range of colours. Due to the design of the twin skin shutter you could, if desired’ have each 100mm deep lath different colours or the outside different from the inside indeed the possibilities are numerous.
The shutters can be provided either hand-chain operated or power operated.
Specification
Curtain formed from pre-galvanized light gauge material, the curtain sections interlocking to provide hollow section lath and the internal air space between the two laths is in-filled with insulating material. The curtain fully assembled is complete with end cast capping to each end of each lath. The lower edge of the curtain comes complete with a rubber weather seal.
The barrel on which the curtain coils is manufactured from mild steel tube, complete with all necessary inner box shafts and helical springs. The size of the barrel and number of springs will be purpose designed to suit specific opening sizes and curtain weights. Where geared shutters are required, the gearing would consist of either spear gearing or chain wheel drive.
Brackets generally constructed from mild steel plates, complete with suitable fixing angles for supporting the shutter at high level off the opening structure. The gear end bracket would incorporate the appropriate spear gearing or chain drive, again dependent on opening size.
Vertical side guides formed from pre-galvanized material and inclusive of vertical brush seal on both inner and outer faces of the guides. The brush seal would run full height of the opening. Where necessary all guides would be complete with suitable mounting angles; again, purpose designed to suit site conditions.
A separate brush head seal would be provided, therefore requiring suitable lintel to which this can be introduced to close off the air space between the curtain face and the lintel face; standard brush seal being able to accommodate a maximum 75mm between lintel and curtain face.

A standard starter unit would also be provided with raise, lower and stop buttons. All electrical equipment would be to suit 380/415 volt, 3 phase, 50 cycle supply (single phase equipment also available).
