Commercial Door Tips and Hardware

The installation of a door in a commercial setting is very different from a residential area. There are certain requirements that must be met for fire safety, and the door is often mounted differently than a residential unit. Here are some tips to help with the installation and safety of your commercial door.

Installation

The door is usually mounted to a concrete frame. You’ll want to use 5” bolts to mount the door if this is the case, but if you’re using a block wall then 4” bolts will do. You don’t want the bolt to extend through to the empty space on the interior of the frame, or the door will have no anchor.

All manufacturers also place their hinges and locks in different positions, so it’s important that you measure out the door frame and make your marks before you attempt installation. If you mount your door with a parallel arm type, you must make sure that it is on the push side of the door. A standard arm will be mounted on the pull side of the door.

Fire Ratings

In order for a door to receive a fire rating, several requirements must be met:

• The hinges must be a steel ball bearing.
• The door must have a closer, it cannot remain open in a fire.
• It must have a latch set so that it can remain closed.
• The door must also have a clear label that designates it as a fire safe door.

If you’re building has four or more floors to it, then all doors in the stairwell must be rated as fire safe.
