If you're remodeling an old building so you can move your inventory and business into a new space, then you'll want high-quality building materials that provide excellent protection against vandals and fires. The doors in your new building are especially important.

Hollow metal doors are popular for commercial use because of their durability and strength. Here are a few reasons to consider installing hollow steel doors in your commercial building.

Hollow Steel Doors Are a Wise Investment

Steel is a good material for commercial doors because steel outlasts wood and aluminum in a busy work environment. Steel doors also perform well on swing testing and field use because steel is such a strong material. Steel doors use steel frames too, which enhances their durability.

Steel Doors Protect Your Building Against Fire

Some hollow steel doors are designed specifically to be used as fire doors. You may want these to protect your inventory or staff in case a fire breaks out in the building. Fire doors are rated according to how long they can hold back a fire, and hollow steel doors can come with as high as a 3-hour rating.

For maximum protection against fire, the fire resistance of the door, the wall, and their location in the building are all taken into consideration when being installed.

Hollow Doors Are Energy Efficient

Using hollow steel doors in your building can also help with energy costs. The space between the steel door panels acts as insulation. The insulating effect can be enhanced by adding polystyrene or polyurethane insulation in the cavity.

The type of insulation that you choose will depend on whether or not you want a fire-rated door. Polyurethane offers the best insulation, but polystyrene is best for fire doors.

Steel Offers Superior Protection

If vandals are a concern in your area, then a hollow steel door is a wise choice. A door designed for security uses thicker steel in the door and frame. This prevents against kicking in the door. The strength of these steel doors also makes them suitable for protection against storms, strong winds, and flying debris.

You can also choose a plain or embossed door, and you can select from a variety of window configurations. These doors have an attractive appearance, which makes them suitable for all types of commercial use.


In addition, steel is an easy material to wipe clean, which makes hollow steel doors easy to maintain so they always look nice for your staff and customers.

Hollow Steel Doors Have Several Uses in Your Building

Hollow steel doors can be used throughout your building. The thickness of the steel and the inner cores vary according to the purpose of the door. The cores can be used to add insulation, block fire, offer soundproofing, and enhance security. Even though the doors look different inside the core, the outside has the same finish so there is uniformity throughout your building.

With all the options available in hollow steel doors, you may need professional help choosing the best doors for your purposes. Whether your renovated space will be large or small, secure doors are important. give us a call today to schedule a consultation.
