# Hollow Metal Doors

## Hollow Metal Doors

### Commercial and Industrial Hollow Metal Doors

Hollow Metal Doors are fabricated of channel reinforced sheet steel and filled with insulation materials such as polystyrene. Standard hollow metal doors are 1 3/4” thick and are prime coat painted (gray). Finish is suitable for painting.

Hollow Metal Doors are shown to have superior performance for strength and durability compared to the alternate materials. Steel can withstand more abuse, is more sanitary, and easier to maintain than wood, aluminum, and fiberglass. Because of their strength and durability, steel doors have the lowest total cost of ownership of any other materials.

We only provide metal doors from manufacturers that meet the strict guidelines of the Steel Door Institute (SDI).
