Life Savers – Hollow Metal Doors
Metal doors are not commonly talked about, but unbeknownst to many, they are seen and passed through millions of people each day around the world. These metal doors play a larger role than just serving as a door. Metal doors are strategic for safety and structural purposes.
Steel doors were seen as so important that a non-profit business association called The Steel Door Institute (SDI) was founded in 1954 to promote the use of steel doors and frames in the construction industry. It sets up the standards for the industry and many of its members are following these safety measures. SDI believes that there are many benefits for using hollow metal doors in architecture. They provide durability, fire-resistant rate, and affordability for the users.
Hollow metal doors are usually made of steel that can last for more than 30 years. Cold rolled steel is the material used in these doors. Steel is known for its strength to endure temperature changes and for its longevity. Hollow metal doors stand strong in the humid weather and will not lose form like wood doors do in a rainy environment. It is a reliable solution to add strength to the structure of buildings.
Doors are an important part of the architecture because they not only offer an entrance and an exit to the rooms in a building, but they are accountable for saving people’s lives. In the case of a fire or other emergency, people are able to escape mainly through doors. The fire rating of a door is determined from Table 715.4 of the International Building Code. A door is expected to last at least 1.5 hours in the event of a fire in the building. For an example, in California, the minimum fire code for a door is 450F and many hollow metal doors can stand up to three hours in a fire emergency. They minimize the transmission of the heat from one side to the other, thus protecting the people and slowing the spread of the fire. The stairwell doors are often made of hollow metal material to give people more time to escape. Therefore, a sturdy steel material door will help the people to evacuate from the building and save the lives.
Comparing wood doors to aluminum doors, metal doors offer much easier and longer life time maintenance. Hollow metal doors start from $120 and go up to $1000 depending on the sizes; however, a solid wood door will cost at least ten times more than a steel door. Hollow metal doors do not require replacements, refinishing, repairs as often as wood or aluminum doors do. Cold rolled steels which are made into these hollow metal doors are recycled steel in the United States. Therefore, hollow metal doors are affordable for many customers. Metal doors are offered everywhere in the United States. The strength, durability and flexibility of hollow metal doors are appreciated among architectures.
Also, on top of its practical safe guard function, doors are also a part of the building’s decoration. The finishing touch of solid color paint or faux surfacing treatment from the metal doors can also bring a vibrant, modern tone for the offices, homes or restaurants. In today’s construction industry, steel is the common choice for doors. It is inexpensive, requires very low maintenance and comes with many styles and colors to choose. Hollow metal doors are truly life savers in homes and commercial buildings.
