Quality & Innovation:
Longstanding Traditions
In 1950, Mark Keymer, a young steel supply salesman, manufactured and marketed a pipe crimper he had invented for installing sheet metal ductwork in heating systems. He insisted on quality construction, setting the benchmark for the new company. More innovations followed for Malco Tools:
- The first hand seamer, or hand brake, featuring compound-leverage handles.
- The time-saving hand notcher, for a V-shaped cut in one motion.
- The hand-operated snap-lock punch.
Just the right tools for crimping, bending, folding or seaming metal. Today, Malco continues the tradition of quality and innovation, and distributes thousands of products from its Annandale, MN headquarters to trade professionals in the U.S. and around the globe.
A proud heritage for a promising future.
