As a trusted distributor of quality door products, CDF is perfectly positioned to supply you with the right metal door frame for your project.

Of course, we stock wood and metal doors, too – plus the quality hardware required for installation. Here are a few of the reasons to choose a CDF commercial metal door frame for your construction site:

• Quality Materials: Each commercial door frame we provide has been crafted using 16-gauge galvanneal steel and has positive locking tabs to ensure rigid assembly connections.
• Trusted Manufacturers: Our partners include some of the most respected door manufacturers in the business.
• Fire Rated: All of our metal door frames are available with your choice of fire rating – up to three hours.
• Custom Options: CDF also provides custom commercial metal door frames for front door style openings. These frames can include windows on both the top and sides as well as special configurations for mullions, wide doors and opposing door swings.

Knockdown vs. Welded Steel Door Frame

Knockdown (KD) steel door frames are made for installation in existing drywall or blockwall openings. A KD steel door frame has interlocking tabs and slots. The frames have visible seams when installation is finished. KD frames are the most affordable because they ship in pieces and require assembly upon arrival at the worksite.

Welded commercial metal door frames are best suited for new construction sites. They're chosen for their seamless appearance and to help ensure that the door frames are square when they're installed. A welded hollow metal door frame is suitable for use in drywall and blockwall openings. They are a bit more expensive because they arrive preassembled and don't require welding or finishing.
