Since 1964, Allegheny has been the world leader in innovative design and manufacture of polypropylene process equipment. Our pickling, cleaning, coating, and plating tanks as well as hoods, covers, and fume exhaust systems have been installed in metal finishing lines around the world. We engineer with plastic stress analysis and finite element design packages to produce polypropylene equipment constructed to the highest fabricating standards. Listed below is some of the equipment that we have pioneered in the conversion from traditional materials to polypropylene construction.
