Brand Spotlight: Malco

We offer many products from several different brands. Whether you’re looking for aviation snips or a combo bender, we have everything for the metal roofer.

Today, though, we wanted to highlight one of our favorite brands: Malco.


Malco Products, SBC began in 1950 when Mark W. Keymer, a young steel supply salesman, decided to begin manufacturing and marketing a pipe crimer that he invented to use in the installation of “new” sheet metal ductwork which are utilized with forced air heating systems.

Additional tools soon followed, and the manufacturing operations of Mark W. Keymer were moved from the garage to the more spacious basement in him home in Minneapolis.

The Malco name came from the combination of his first name and the first name of an early associate, “Mark and Al’s Company.”
