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.

  frames perform best when Mother Nature's at her worst.

• Energy efficient: Up to four times more efficient than wood doors, steel doors and frames allow minimal air infiltration, which results in less energy loss between the door’s interior and exterior surfaces.
• 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.
