75MM STEEL SHUTTERS
S75 Steel Shutters
Curtain – Roll formed in-house from Australian made ‘Bluescope’ z275 galvanised steel, S75 curtains are available in 75/0.8mm profile, or 75/1.0mm profile (depending on opening size, and application). Our slat profile has been designed to allow maximum compatibility with other manufacturers profiles to maximise options should repairs be required in the future.
Aluminium Bottom Rail – Made from locally extruded Aluminium, the bottom rail is a ‘T’ shaped section that is the last slat on the curtain, and fitted with a rubber weather strip to seal the door when closed. Optional steel box or steel reinforced bottom rails are available upon request
Drum – made from C350 seamless line pipe with diamater and wall thickness to suit door size. Cold drawn 1020 solid bar axles which are mounted on 38.1 ID sealed roller bearings. Australian made helical springs (for sprung doors)
Clips – made from high quality ‘Dupont’ plastic, the clips are designed to prevent sideways movement within the curtain, while also keeping things quiet
Guides – Roll formed in-house from Australian made ‘Bluescope’ z275 galvanised steel, guides are available in either 75 x 30 x 2, heavy duty 100 x 35 x 2.5mm, or wind lock 103 x 35 x 3mm.
Perforated and/or Slotted slats provide ventilation, and vision through the door and are available upon request.
Slotted slats provide approx. 26% free air
Perforated slats provide approx. 33% free air
Windlocks – S100 shutters can be wind locked to provide mechanical protection against wind load if required. Cast wind lock clips are installed every 2nd, or 4th slat (depending on opening size).
Operation – Operation of a shutter can be by hand (up to 5m2), via a chain hoist (manually), or via a motor. We work closely with Grifco – stocking many of their products from the industry standard ‘E-Drive’ models, the older style ‘M-Drive’ motors, and the new D-Series units
Locking – Typically a shutter is large enough that it doesn’t need to be mechanically locked – as its considered ‘locked’ under its own weight and via connection to the motor. However, for smaller doors where mechanical locking is required – there are a variety of options including (but not limited to) ‘Shoot Bolts’ – which lock the door by shooting through the back of the guide; ‘Floor Locks’ which typically lock the bottom rail to the floor, and orb locks – which are fancy shoot bolts. We recommend you discuss your locking requirements with your local Sprint representative
Finishes – Doors can be supplied in Galv (silver), or have a ‘powder coat’ colour finish applied. Sprint works with the Dulux ‘Duralloy’ range of colours as standard. However Dulux’ other ranges (Duratec, etc) are available upon request (additional cost applies). *When selecting powder coat, please be aware that Sprint’s standard finish coats both sides of each slat to give colour finish inside and out. This is a superior finish to one side (both sides have an extra layer of protection), plus the cost saving of coating one side vs both sides doesn’t stack up. So we can coat one (1) side if required – but it is not any cheaper.
What does your shutter weight?
100/0.8mm = approx. 12.4kg p/m2
100/1.0mm = approx. 15.2kg p/m2
*this calculation is based upon opening size, and does not account for the drum or motor – which adds additional weight depending on opening size. Please contact your Sprint Representative to enquire about more accurate weights if required.
