About Montgomery Plant
The Montgomery plant has been in operation from the current location since 1976. The plant is built differently from the Willsgrove plant and uses tunnel kiln. Tunnel kiln is a continuous moving ware kiln in which the clay products to be fired are passed on cars through a long horizontal tunnel. Better heat distribution results in uniform temperature across the kiln cross section in the firing zone thereby resulting in a higher percentage of good quality bricks. This is demonstrated in the high compressive strength of Macdonald bricks and their good reputation with engineers.
