Commercial Heavy-duty Steel Doors For Your Door Projects For Your Commercial, Industrial, and Institutional Applications

Commercial Steel doors are widely recognized as the best value in the door industry. Most metal doors outlast their wood counterparts by over 10 years, are better insulated, vandal resistant, and longer lasting than wood doors or fiberglass doors. These doors are most commonly used on the exteriors of a commercial building, and on fire rated openings as they are inexpensive, and can handle ratings up to 3 hours.

Our Commercial Steel doors are made using a hollow Steel shell that is then re-enforced and filled with insulation. Our doors are supplied from manufacturers that meet the strict guidelines of the steel door institute, as well as testing from Underwriters Laboratories (UL), National Fire Protection Association (NFPA), American National Standards Institute (ANSI), and American Society for Testing and Materials (ASTM). 

You'll find industrial steel doors in just about every public building. Schools, stores, offices, hospitals, manufacturing plants and other facilities have commercial steel doors specially designed to handle heavy traffic areas. 

It's widely acknowledged in the door industry that commercial steel entry doors are the best value. They generally outlast wood doors by more than 10 years and are very affordable. In addition, a commercial steel door is better insulated than wood or fiberglass. Commonly used on commercial building exteriors, our commercial fire-rated doors can handle ratings up to three hours, meaning they're suitable for fire-rated openings. 

When you choose a commercial steel door from CDF, you can also be assured of its security. These vandal-resistant steel doors make it difficult for intruders to enter your building – giving them a big advantage over their wooden counterparts.
