If you’ve ever ordered the wrong commercial door frame, you know how quickly a project can go off track. In this video, we break down the key differences between knockdown (KD) and welded door frames so you can choose the right option with confidence and avoid delays, rework, and added costs.

 

Quick Answer: Knockdown vs. Welded Door Frames

The primary difference between a knockdown door frame and a welded door frame is how the frame is manufactured and installed. Knockdown door frames (KD frames) ship in multiple pieces and are assembled on-site, making them ideal for drywall construction, interior commercial doors, and renovation projects. Welded door frames ship as a single welded unit and are commonly used for masonry walls, exterior commercial openings, and high-abuse environments where additional strength and durability are required.

Both knockdown hollow metal frames and welded hollow metal frames are commonly used in commercial buildings, schools, healthcare facilities, warehouses, and office buildings. The best choice depends on the wall type, installation conditions, project timeline, and whether the opening is located indoors or outdoors.
