Steel doors, along with wooden and fiberglass doors, are among the most popular for exterior door options. There is a good reason for this popularity with homeowners.
These doors are cost-effective compared to other exterior door options and they are long-lasting and versatile in style.
How are Steel Doors Made?
Steel doors consist of two sheets of galvanized steel that has been stamped with a design and an inner foam core. The most common foam cores are polyurethane and polystyrene. There are solid steel doors that are used for security or military applications. They are too heavy for standard home use. In addition to the steel sides and core, there are the edge assemblies and hardware.
Certain door styles, steel entry doors, have glass built into the frame. Glass can make the steel doors more attractive and bring light into interior spaces. Yet, glass decreases the energy efficiency of exterior steel doors. Also, if you are interested in steel doors for security, glass can increase the security risk.
Manufacturers finish steel doors in the factory with a spray-coated layer like powder coating or epoxy. This creates a smooth finish and comes in a variety of colors. Others have a vinyl coating. This can create a textured finish that they make resemble a wood texture.
