A commercial steel door can last 30 years or more with proper installation and minimal maintenance. This video goes over how to install a commercial steel door in order to ensure a great fit.
Most steel doors measure 36” by 84” and are fitted with steel between 16 and 24 gauge. A standard 18 gauge 36” by 84” door would weigh around 106 pounds.
Most steel doors also have a polyurethane or polystyrene core that aid in insulation. According to the department of energy, steel doors offer five times the insulation of a similar-sized solid wood door, increasing a room’s thermal efficiency.
Apart from durability and thermal efficiency, they are also fire resistant, weatherproof, highly recyclable, and sound resistant. When installing a commercial steel door, ensure that the correct hinges (standard or heavyweight) are used. Consulting the hardware schedule will provide the necessary information. Finally, before installing, it’s important to check that the door frame will fit the door. This means checking that the frame opening is level, plumb, square and true.
If you need any help during this process, it’s best to contact a door company to help you. When doing this on your own, remember this article.
