In most cases the following alternatives can be offered either singly or in combination: 22swg or 18swg galvanised steel; Colorcoat HP200 plastisol coating; polyester powder coating; punched or slotted lath; perforated lath.
CURTAIN GUIDES
The vertical curtain guides are constructed from cold rolled steel channel, of various dimensions as dictated by the amount of security required or the size of the door, mounted on continuous mild steel angles for fixing to the jambs.
BOTTOM RAIL

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 achieve 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 appropriate size and thickness for the weight and dimensions of the door. 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 steel pins which locate through the curtain and guides), with a mild steel housing welded to the guide.
