We are widely respected for our work with two related specialties within plating, too: pretreatment systems, and material handling. Walgren has numerous proprietary material handling solutions that minimize footprint and energy use, and simplify waste management.

Customers choose Walgren because the plating systems we have installed at OEM facilities, tier 1s and military bases have an impressive track record for reliability and performance.

In 2015, Walgren was acquired by George Koch Sons, a diversified global manufacturer of large scale finishing lines with an impressive aerospace track record of its own.
