York Building Products Company has been supplying quality products to the building industry for over 60 years. Throughout that time our manufacturing focus has expanded from gray block to architectural block, retaining wall systems and colored mortar. In addition, the company has developed quarries and mining operations throughout south central Pennsylvania and northern Maryland from which we supply stone, sand and gravel to our own block manufacturing plants and bituminous asphalt plants as well as other manufacturing customers, state, commercial and residential construction projects. York Building Products vertical integration enables us to control our product quality from the raw material stage through the entire manufacturing process. The product quality is monitored at each step of the way to insure we meet or exceed the highest industry standards. The company's diverse product offering enables the customer a single source for many of their building product requirements. York Building Products includes 3 bituminous asphalt plants, 3 sand and gravel operations, 2 stone quarries, 7 block plants, 1 mortar facility and two "factory outlet" retail stores serving distributors, contractors and homeowners in the Pennsylvania, Maryland, Delaware, Washington DC and Virginia markets.
