Metal Manufacturing Industries

Manufacturing hollow metal doors and steel frames in Mexico since 1999. Our products protect buildings and people every day — proving their durability and performance on projects across Mexico and around the world.

Our Products

MMI's hollow metal door designs give architects, specifiers, and contractors the range they need to meet every opening requirement. Across Latin America, and particularly in Mexico, construction has modernized around standardized door and frame sizes — making supply and installation faster, simpler, and more cost-effective. MMI engineers its product lines around that reality.
