In 1946, a modern office and warehouse was built in Bethlehem, which facilitated innovative methods of material handling such as palletized storage, forklift trucks, and conveyors to move large quantities of sand and stone. In the 1950s and 1960s, new product lines were added including face brick, fireplace products, gypsum drywall, kitchen cabinets, and appliances. Delivery capabilities were greatly expanded with the introduction of boom trucks for delivery of bricks, palletized bagged goods and drywall.
In the next 2 decades, the third generation of the Black family became associated with the company. The 1970s was a period of rapid change; the firm’s kitchen cabinet business grew into a separate department specializing in stock and custom cabinets for both builders and home owners. Custom design and installation services were added.
A Commercial Door and Hardware Department was established in 1975. This department, featuring hollow metal doors and contract hardware, became the cornerstone of the firm’s commercial sales effort; and soon included wood doors, washroom accessories, toilet partitions and other specialties.
