Why Steel?

Superman is called the "Man of Steel," we "steel" ourselves for unexpected news, characters in books and movies are often described as "steely eyed." When we think of steel, we think of strength.

But there's more to the story - a lot more. Steel doors and frames manufactured by SDI member companies are more than just strong, they're:

• Fire resistant: SDI steel doors and frames conform to NFPA 80 and stop the spread of smoke and flames. The strength of steel doors and frames frustrates attempts to break in or break through. View Fire Door Req. Fact File

• Can be designed to fit nearly any application: Interior or exterior, office, industrial or institutional - steel doors and frames can fit nearly any opening, and any design you can imagine. View Design Porfolio
