CURTAIN

The shutter curtain is constructed from 20swg galvanised steel interlocking lath as standard. Nylon endlocks are riveted to both ends of alternate laths to prevent lateral movement.

Options

In most cases the following alternatives can be offered either singly or in combination: 22swg or 18swg galvanised lath; Colorcoat HP200 Plastisol coated lath; polyester powder coating; punched/slotted lath and perforated lath.

BOTTOM RAIL

The curtain bottom rail is constructed from a braced single or double mild steel angle(s), of various dimensions as dictated by the size of the door.

Options

Purpose made rubber weatherseal can be fitted to accommodate minor floor irregularities and provide resistance to rain water ingress. A tapered bottom rail can be provided to accommodate sloping floors. We recommend that the threshold be formed with an incline away from the opening to allow run-off and prevent pooling.

BARREL ASSEMBLY

The barrel, which is usually fixed behind the lintel, is constructed from mild steel tube of sufficient diameter and wall thickness to withstand deflection and twist during operation. Counter balancing is achieved by helical torsion springs mounted on a steel shaft incorporated within the barrel and greased on assembly. Spring and shaft supports are cast steel.

SUPPORTING BRACKETS

Supporting brackets are constructed from mild steel plate mounted on mild steel angle cleats for fixing to the lintel and are of suitable size and thickness for the weight and dimensions of the shutter. Cast iron or welded steel cups are fixed to the end plates to receive the barrel's centre shaft.

LOCKING ARRANGEMENTS

Locking is by means of a pair of guide locks (brass cylinders with pins that locate through the curtain and guides) with a mild steel housing welded to the guide

Options

An espangolette lock, high security ground lock or shoot bolt(s) to receive customer's own padlock can be fitted in addition to, or in place of, the standard guide locks.

HOOD, FASCIA AND SOFFIT

A galvanised sheet steel hood / canopy can be supplied to enclose the barrel assembly.

ELECTRICAL OPERATION

Electrical operation can be provided, at extra cost, by means of a 240v single phase tubular motor with integral limit switches to control the travel of the shutter curtain. Open and close activation is by means of simple rocker switch. A manual override device can be included for emergency operation in the event of a power failure.

Options

A key operated switch can be supplied for external applications or to restrict operation to authorised personnel. A variety of safety facilities and other operating equipment, including remote control, are also avaliable.
