Hollow metal doors combine reinforced steel sheets and insulated cores to deliver commercial-grade strength, fire resistance, and long-term value for commercial and industrial buildings.
Standard hollow commercial metal doors are 1-3/4″ thick and painted with a prime coat suitable for painting.
Hollow metal doors deliver durability and strength compared to alternative materials. They withstand heavy use and resist damage better than wood or aluminum doors, and they require less maintenance over time. As a result, metal doors offer the lowest total cost of ownership of any door material.
In addition, Doors Unlimited offers a complete line of hollow metal doors for both new construction and retrofit projects across institutional, industrial, and commercial markets. We only provide hollow metal doors from manufacturers who meet the strict guidelines of the Steel Door Institute (SDI).
Carrying Steelcraft hardware prep locations in stock, but also offering replacement or retrofit doors with hardware prep locations from all manufacturers, including Mesker, Ceco, Curries, Old Republic, and Pioneer.
