COL-MET began as Oak Cliff Metal in 1957 and primarily manufactured building products for Dallas-Ft.Worth-area contractors and businesses. On February 4, 1958 James Collier Sr. obtained a patent for galvanized clip edging beginning a new chapter for the company. In the early 1970s, at the request of local nurseries, Oak Cliff Metal began manufacturing galvanized sign holders. Oak Cliff Metal moved to Garland, Texas in the 1980s and transformed into Collier Metal Specialties. COL-MET then began producing stake type steel lawn edging at the request of their existing nursery and landscape customers to offer professionals an affordable, long lasting solution to retain mulch, rock, and stone in various landscape designs. The headquarters moved to their present location in Garland,Texas, in the late 1990s and now has expanded production capabilities and a 125,000-square-foot manufacturing facility.
