Parts of a Rolling Steel Door

Posted by Wendell Daguno on Tue, Mar 25, 2014 @ 09:00 AM

Rolling steel doors are an extremely useful part of the dock and door system for many commercial and industrial organizations. These doors are great for security and easy to use too. Properly maintaining these doors requires teamwork between your own maintenance crew and an expert in commercial overhead doors. One of the best ways to determine what maintenance and repair work needs to be done and when is by better understanding the different parts of an overhead door system.

Some of the more noticeable parts of a rolling steel door include:

Rolling steel door parts

  • Curtain – This is the “door” itself—the steel curtain is what covers the majority of the space when the door is closed and it is tucked away when open.
  • Slats - Each of the individual section of the curtain is called a slat. These are connected in a way that they can make the door "roll up" when it is in an open position.
  • Springs – With a name like “rolling steel door,” you may think that springs wouldn’t be necessary. However, springs are one of the things that give the door tension and keep it open when it should be.
  • Counterbalance System – This is the physical part that helps the door open and remain open.
  • Seals – Seals are installed around all edges of the door to insure that temperatures stay as consistent as possible when the door is in the closed position.
  • Motor – Some of doors are motorized and as such have a mechanical system that allows you to open and close with just the press of a button.
