Garage Door Glossary

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:

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.
