Colonial commenced its
operations in 1929, originally under the name
Colonial Mirror and Glass Corporation, as a manufacturer of mirrors and a processor of flat glass primarily for sale to store fixture manufacturers and glazing contractors.

Through the acquisition of automated fabricating equipment, Colonial expanded its operations to include the processing of flat glass products for sale to architectural woodworkers and industrial glazing concerns.

In 1957, Colonial relocated and expanded its facilities to accommodate an automated mirror silvering conveyor system. In the same year it commenced the distribution of flat glass purchased from domestic and foreign manufacturers. Colonial thereafter increased its production capacity and efficiency through the acquisition of additional space and the installation of modern polishing equipment and beveling machinery.

 


In 1979, Colonial entered the Tempered Glass business by acquiring a 43,000 square foot facility on Kent Avenue in Brooklyn and purchasing a computer controlled glass tempering furnace.

 

In 2002, Colonial began operating under the lean enterprise model, converting Colonial’s production system to one of lean manufacturing. Transforming Colonial from a traditional batch-and-queue production facility where only one glass thickness is ran per day to maximize yield, into a flexible system where each thickness is ran daily, sometimes even more than once, as a mean to better service Colonial’s growing customer base. As a result, Colonial’s on-time performance percentage rate and production capacity has increased significantly each year over the past 4 years. In 2005, Colonial introduced two new product lines: InsulSteel insulated glass units and SafetySteel security glass. These 2 new product lines join Colonial’s existing GlasSteel Tempered Glass, GlasSteel Tempered Doors, and GlasSteel Shower Doors product lines, further broadening Colonial’s efforts to become a one stop shop for all of their customers’ glass needs.

In 2006, Colonial reengineered its lean factory systems to expand capacity, enhance quality, and improve on-time performance:
    upgraded cogeneration system;
    second tempering oven;
    automated cutting system;
    hole & notch machine;
    expanded delivery fleet.
