Steel Doors

Perhaps the biggest advantage that steel doors offer over their wood and fiberglass counterparts is enhanced security. These doors are frequently used as rear and side entry doors because these locations are often not as well-lit or as visible as front entry doors and thus are more vulnerable to intrusion. They are also frequently used in settings where they will be subject to impact, such as from flying debris, and as the basis for fire-rated doors.

Door Construction

Steel-doors are not solid, but rather are made of a wood, foam, or composite core that is encased in steel. Steel doors are often categorized as hollow metal. This type of construction offers improved energy efficiency, better sound insulation, and improved fire-resistance. When choosing a steel door, buyers should take note of the thickness of the steel coating, as some doors are thicker than others and thus offer greater security as well as resistance to denting.  

Galvanized steel, which is steel coated in zinc oxide, is resistant to corrosion. Galvanized doors last much longer than non-galvanized doors and often come with lifetime limited warranties. For the marginal increase in cost, it is well-worth the investment to upgrade to a galvanized steel door.  

Steel doors often cannot be customized to the degree that wood and fiberglass doors can be customized. While buyers have some control over materials and colors used to finish steel doors, there are few other design freedoms. In many cases, steel doors can be purchased off the shelf with a base of white or grey primer and then painted to match a particular aesthetic. Custom painting techniques can help to add texture and patterning to steel doors.
