WELCOME to Vintage Plywood Mill Works. We produce mid-century modern wooden ceiling tiles and accent wall paneling. This unique MCM grooved, or ribbed plywood was popular in the 1940’s – 1950’s. The brand name was Weldtex, but it was also known as combed or striated plywood. We supply this not only in 3/8” thick pine plywood ceiling squares, but also in a number of plank style hardwood species for unique accents walls.
