What Is A Hollow Metal Door In Construction?

Hollow metal doors are highly popular in commercial and industrial construction due to their sturdy frame, comprised of steel with steel panels laminated to both sides.

They are equipped with mounts for hinges and a pocket for a mortise lock, allowing it to easily fit into different applications.

Hollow metal doors also provide excellent soundproofing and thermal insulation performance, making them a great choice for businesses looking to create comfortable environments.

What Are The Advantages Of A Hollow Metal Door?

Hollow metal doors provide excellent durability and are highly resistant to impact damage, wear and tear, and rust. They are an ideal choice for environments that require a higher level of security such as schools and hospitals.

Hollow metal doors also offer quick installation speeds, soundproofing capabilities, improved fire safety protection (depending on the material used), and better thermal performance than other doors.

Furthermore, hollow metal doors tend to stay looking newer for longer periods of time as they can be painted or powder-coated to match almost any aesthetic.

Finally, these doors may require less maintenance than other types of doors thanks to their toughness.

What Is The Difference Between A Hollow Door And A Steel Door?

The main difference between a hollow door and a steel door lies in the material used to construct them. Steel doors are made from the metal of varying thickness, which is measured in gauges, while hollow doors only consist of wood and some layers of insulation materials.

Hollow doors are lighter than steel doors, however, they provide less security due to their weaker construction materials.

Steel doors, on the other hand, provide greater protection against forced entry but come with a much higher price tag due to the costly metal used in their construction as well as their heavier weight.

Furthermore, while steel doors usually require more maintenance such as painting or rust preventive measures over time, hollow doors can be easily wiped down or painted for an aesthetic upgrade.

Where Are Hollow Metal Doors Used?

Hollow metal doors are widely used in both commercial and industrial settings for interior, exterior, and fire-rated door openings.

These doors are custom manufactured to precise specifications by a professional commercial metal door and frame specialist based on the requirements of the project. They come in various sizes, colors, and finishes as well as with a variety of hardware options.

Hollow metal doors offer higher resistance to dust and moisture due to their tight seals and heavy construction materials.

In addition, they provide superior soundproofing characteristics that help reduce noise pollution in busy environments. The fire-resistance rating of hollow metal doors is also higher when compared to wood or plastic alternatives, making them ideal for areas that require extra protection from potential fires or smoke infiltration.

Which Hollow Metal Door Core Is Most Commonly Used In Temperature-Rise Doors?

Honeycomb is the most commonly used hollow metal door core for temperature-rise doors, due to its heavy-duty and durable composition.

It can be fire-rated up to 3 hours, although its insulation value is not as great as a foam core. Nevertheless, it can still be used at exterior openings when cost-effectiveness is desired.

What Are The Different Types Of Hollow Metal Doors?

The four main types are cased open, single rabbet, double rabbet, and double egress.

  1. Cased open hollow metal doors feature an overlapping frame that is designed to accept a variety of hardware attachments and finishes.
  2. Single rabbet hollow metal doors feature standard specs and dimensions but offer less sound control than other styles.
  3. Double rabbet hollow metal doors provide superior sound control due to the extra rabbet located on the inside perimeter of the door.
  4. Finally, double egress hollow metal doors offer two sets of locks that allow occupants to escape quickly in case of emergency situations.
