Commercial Steel Window Restoration

Vintage Steel Window Restoration

Many vintage windows are steel, representing a significant portion of windows in historic structures, especially in industrial and commercial buildings. Structures that have steel windows are very distinct, often with unique character.
Replacing, rather than restoring these windows, can make the building look out of sorts if replacement windows are not of a similar era or style. Keeping and restoring your steel windows can be a viable option for your building and your budget.

Steel windows offer a lot of benefits…

Steel windows are strong! Steel windows are very durable, and the material can last ages. Steel has become the standard material when it comes to strength-building products. You’ll find steel components as the centerpiece material when it comes to building the tallest and most robust structures in the world.

While strong in structure and material, steel windows, just like wood windows, can succumb to the elements and show signs of deterioration. The good news is that, like wood windows, this deterioration can be remedied. Minor deterioration, such as surface rust, can be ground and refinished. More major components and sections can be removed and spliced with a compatible product.

Vintage windows are solid in structural integrity. Windows built with strong, rolled steel can provide an extra sense of security for building owners — both through security in the strength of the window — and the security that protects valuables by keeping unwanted intruders out.

Steel windows can be efficient. Because of their structural integrity, properly installed steel windows are less likely to sag or shift, virtually eliminating the incidence of gap-related drafts as the windows age. Steel windows that were originally fitted correctly and installed well stay square. The components holding the windows in place may need maintenance from time to time, but the steel material won’t sag.

Steel windows can be repaired, restored, and upgraded. It’s possible to repair rust and defects to give your windows a renewed appearance. Advances in glass materials have made upgrades in steel window glazing a winner as well!
