What is the difference in a hollow door and a steel door?

A hollow door and a steel door differ in their construction material and design, which impacts their strength, durability, and insulation properties.

A hollow door is typically made of a lightweight material such as cardboard or MDF (medium-density fiberboard) with a thin veneer or laminate covering. The interior of the door is essentially hollow, with only a thin frame and support structure holding the door together. Hollow doors are often used as interior doors in residential buildings, where they provide basic privacy and sound insulation.

A steel door, on the other hand, is made of steel or other metal alloys, which makes it much stronger and more durable than a hollow door. Steel doors are often used for exterior doors in commercial and industrial buildings, as they provide excellent security, weather resistance, and fire resistance.

In addition to their different construction materials, steel doors and hollow doors also differ in their design features. Steel doors typically have thicker frames, hinges, and locking mechanisms, which make them more resistant to forced entry. They may also have insulation materials inside the door itself to improve energy efficiency and reduce noise transmission. Hollow doors, on the other hand, have a simpler design with fewer features and are primarily used for their lightweight and low-cost advantages.

Overall, the main difference between a hollow door and a steel door is their strength, durability, and intended use. If you need a door that provides superior security and weather protection, a steel door is likely the better choice. If you need a basic interior door for a residential building, a hollow door may be sufficient.
