Steel doors - commonly referred to as hollow metal doors - are the most widely used door type incommercial construction. This guide explains when steel doors are the right choice, what problemsthey solve, and why they are preferred over wood or fiberglass in demanding applications.

Durability is the most common reason steel doors are specified in commercial buildings.Wood doors can dent, chip, split, or warp over time. Exposure to temperature changes causes wood toexpand and contract, often leading to long-term alignment and clearance issues.
Fiberglass doors face similar problems, including surface cracking, fading, and structural weaknessin high-traffic environments.
Steel doors, by contrast, are constructed from cold-rolled or galvannealed steel with an insulated core.While steel will naturally expand and contract slightly with temperature changes, it does not crack orwarp structurally. Any surface issues are typically limited to paint or primer and can be easily refinishedwithout affecting the door’s integrity.
Steel doors offer significantly higher security than wood or fiberglass alternatives.They resist forced entry, blunt impact, and repeated abuse far better than other door materials.
A steel door may dent under extreme impact, but it remains functional and secure.Penetrating a properly constructed commercial steel door is extremely difficult.
Additional accessories such as kick plates, hinge guards, latch guards, and armor plates can furtherincrease durability and security in high-risk areas.
When evaluated on a cost vs durability basis, steel doors are often the best value in commercial construction.They are typically less expensive than solid-core architectural wood doors while offeringsuperior lifespan, lower maintenance, and higher security.
Steel doors also eliminate the cost of specialty wood species, veneer matching, and prefinishing.A factory-primed steel door can be painted to match any design intent at a fraction of the cost.
When a fire-rated opening is required, steel doors are the industry standard.Commercial hollow metal doors are available with fire ratings ranging from20 minutes up to 3 hours, depending on the tested assembly.
Fire-rated steel doors are commonly required for:

Steel doors are the preferred solution for exterior openings exposed to weather, moisture, and temperature changes.High-quality commercial steel doors are manufactured from galvannealed steel,providing corrosion resistance and long-term durability.
Steel doors can be installed in virtually any wall condition, including:
Frame type, anchors, and door construction should always match the wall condition and application.
Commercial steel doors are commonly specified because they can meet:
Choosing a properly constructed steel door ensures smoother inspections, longer service life,and lower total cost of ownership.
