Welcome to RT Materials, a full service Building Materials distributor. The company was incorporated in April of 2009 as MBE Construction Services Inc. and on July 2010 assumed the corporate name of RT Materials. In December of that same year RT Materials became certified by the City of Chicago as a Minority Business Enterprise (MBE). Over the past three years RT Materials is the fastest growing building materials distributor in the Chicagoland market. We have earned the reputation for superior quality service with reliable on time deliveries. We take great pride in the fact that RT Materials is a true bonafide MBE distributor, with a vast inventory of building materials and experienced Union labor.
