About Collomix

Collomix traces its roots to the early 1970s in Germany, when a rapid growth in the use of ready-mix materials in construction met a recognition of the need for quality tools dedicating to mixing. Since 1975 with the development of its first mixing paddle, Collomix has been meeting that need, and exceeding customer expectations. Today, millions of paddles, mixers, and systems later, Collomix is a trusted global leader providing quality mixing tools and accessories that stand the test of time.
