From Chicago distribution to global manufacturing excellence.
STZ Industries traces its origins back to 1935, when G&S Supply was founded in Chicago as a local distributor of plumbing products.
In 1984, the company expanded into manufacturing under the LDR brand, supplying major home centers, hardware distributors, and mass-market retailers across the United States.LDR was acquired by Coda Resources in 2015, strengthening the group’s US footprint.
In 2019, the company restructured its product lines, selling its fashion plumbing division and adopting the name STZ Industries.
