Garage doors are far more complex than your normal household door. Here we make sense of some of the industry terminology you might hear, and what they mean:
Astrangal – This is a weather seal which covers the bottom of the garage door, guarding against drafts, rain and bugs.
Cable Drums – Designed to collect and dispense the cables neatly and without tangling. They are positioned on the torsion springs.
Cable Safety Device – A safety measure which prevents the garage door from falling if the cable breaks.
Curtain – The face of the door.
Cycle – A term used to describe the lifespan of torsion spring doors, for example 100,000 cycles. One cycle means: fully closed > open > fully closed again.
Galvanizing – A method used for coating steel garage doors to prevent rusting.
Gauge – A measure of how thick or thin a steel door is. A higher gauge means thinner steel.
Guide Rail – This rail runs either side of roller door frames to help the door stay straight for a secure close.
Jamb – The vertical framing of the door opening.
Jamb Seal – The weather seal that runs alongside the jamb.
Top Header Seal – The weather seal that runs along the top side of the garage door.
Torsion Springs – Help to raise and lower the garage door
Torsion Springs (Counterbalance assembly) – Ensures that the door weight is evenly distributed when opening and closing.
Track – The path which guides the door when opening and closing.
Radius – The curved part of the track where vertical turns to horizontal along the ceiling.
Rollers – The wheels which travel along the tracks when the door opens and closes.
Windload – The force of the wind as it hits the garage door in a closed position.
