Quick Answer: How Do You Choose the Right Commercial Door Frame?
Choosing the right commercial door frame depends on the wall construction, opening type, fire rating requirements, and installation method. The two most common commercial door frame types are welded frames and knockdown (KD) frames. Welded door frames are typically used for masonry walls, exterior openings, and high-abuse applications, while knockdown door frames are commonly used for drywall construction and interior commercial openings. Selecting the correct hollow metal door frame helps ensure proper installation, code compliance, long-term durability, and accurate door operation.
