Standard Specification
Modes of Operation
The Safeguard 76 and 100 Roller Shutter can be operated manually or electrically, depending on your needs. Manual operation is available via a hand chain, assisted by reduction gearing and mechanical springs housed within the barrel. This includes a safety brake as standard. Electric options include a 3-phase 415v Safedrive motor with an integRAL safety brake and a 60% duty rating, or a single-phase 240v tube motor, which also comes with a safety brake.
Curtain
Safeguard 76 - The curtain is constructed from 76mm deep, galvanised cold-rolled concave sections of steel, tailored to the required gauge for strength and durability.
Safeguard 100 - The curtain is constructed from 100mm deep, galvanised cold-rolled flat sections of steel, tailored to the required gauge for strength and durability.
Each alternate lath is fitted with endlocks to prevent lateral movement, while wind anchor s are incorporated on larger shutters. Perforated versions are available, featuring micro circular holes to allow ventilation without compromising security.
Bottom Rail
At the base of the curtain, a robust steel angle reinforcing rail is fitted to form an inverted ‘T’ shape. This reinforcement adds stability and ensures a tight seal when the shutter is closed.
Side Guides
Side guides are formed from cold-rolled mild steel channel sections, fixed securely to the structure with full-height mild steel fixing angles. These guides ensure the smooth and stable operation of the shutter curtain.
Roller Assembly
The roller assembly is built from a mild steel tube fitted with high-tensile helical counterbalance springs, mounted on bright steel shafts running in ball races. Where required, machine-cut steel gears or chain drives are included to suit the size and weight of the shutter opening, ensuring reliable and balanced operation every time.
