Why Our Steel Windows and Doors Instead of Aluminum Systems?
Steel is three times stronger than aluminum
Steel frames are welded at the corners, without the unattractive join lines or design vulnerabilities of aluminum frames
Steel’s superior strength also allows for longer frames on larger windows
Steel frames create narrower sightlines, reducing the ratio of glass to framing and lowering the U-value
Steel is five times more thermally resistant than aluminum
Steel can transcend architectural styles, from urban commercial to modern luxury residential
Steel is 100 percent recyclable
Our steel-frame systems are powder coated and hot dipped in a galvanized substrate for superior corrosion resistance

Choose from Thermally Broken and Non-Thermal Steel
Thermally Broken Steel Windows and Doors
Citadel’s thermally broken steel window and door profiles prevent the cold outside from traveling through the frame into the interior. With thermally insulated barriers between the interior- and exterior-facing frame sections, our CWD product lines offer NFRC-certified energy efficiency and U-values as low as 0.17.
