G&S Supply was formed in Chicago in 1935, locally distributing plumbing products. In 1984 G&S began to manufacture product under the LDR brand and expanded their business by supplying home centers, hardware distributors and mass merchants their plumbing supplies. LDR was then acquired by Coda Resources in 2015. In 2019, LDR sold its fashion plumbing business and changed its name to STZ industries.Shop All STZ Industries ProductsVisit STZ Industries Website
