2Fold® doors are made with solid steel. Steel allows us to build the thinnest frames possible. This maximizes your view and is sturdy enough to withstand the strongest winds. Steel is the only way to get to the holy grail of elegance and strength when building doors and windows.
The moving panel frames are only 1″ wide but over 2-1/2″ deep and fully welded. They won’t sag or distort over time, nor will they rust or leak at the corners. Rust and leakage can be a problem with aluminum or clad doors.
We treat the solid steel in a very special way by stripping it of all of the surface impurities through white sandblasting. Then it is coated with the world’s best primer: a protective coating that is 83% zinc to prevent rust.
Your contractor can paint the frame or we can provide the topcoat to match your specification. Our topcoat comes with a warranty of up to 15 years.
