Steel gauges for doors


Depending on the application, there are three reasons why you should consider hollow metal doors with heavier gauges:

  • Structural strength: Heavier gauge means more rigidity thus longer lifetime for the door opening.

  • Security: A heavier gauge door is more difficult to compress at the lock location.

  • Resistance to dents: A heavier gauge door is more difficult to damage.


In high abuse and high security areas, heavier gauges should be part of the product selection criteria.
