Common materials for commercial doors include some of the following:
Hollow metal doors are the most common. They are long lasting and affordable. They can be customized in many styles and colors, and used for many different applications.
Galvanized steel doors are frequently used for exterior doors because they resist rust formation.
Aluminum doors are strong without being heavy.
Glass doors are used for both exterior doors and interior doors, and can be a beautiful addition to your workplace.
If you have any special considerations for your office door installation, make sure you discuss it before the installation begins. This might include security levels, door alarms you are going to want installed along with the new doors, or emergency exits in your building. You will also want to consider how employees will gain access to the building.
