Interior S40 Windows and Doors

Interior Steel Windows and Doors

At The French Steel Company we offer both interior and exterior windows and doors for our Tuscan Series. Our exterior Tuscan Series is a thermally broken Secco profile. The S40 profiles are a non-thermally broken system that allows clients to use the thinnest possible sightlines inside their home or business. This interior steel door option is great for window walls, interior doors, and even wine rooms.

These slender and minimalist windows sacrifice nothing in terms of durability, security, or safety. Our S40 can be hand crafted and designed for various applications. We offer several finishes, hardware options, and sizes. 

The Durability and Versatility of S40 Doors and Windows

The S40 profile is part of French Steel’s Tuscan Series of high-quality, elegant, durable steel windows and doors. It features profiles made of cold-formed galvanized steel, allowing profiles to be folded into finely detailed shapes. These sheet metal profiles are then laser welded into the tightly interlocking shapes that hold the glass portion of doors and windows tightly into place and seal your home or property against the elements while letting plenty of light in.

Whether fitted flush or overlapping, S40 offers clear and unobstructed views, creating visually appealing spaces.

Versatile Hardware Options:

We offer a range of concealed and visible hardware options to compliment various designs.

Seamless Interior Design Integration:

A wide selection of glazing beads allows for a seamless integration of windows into the home’s design.

This line of hot-rolled and cold-formed steel is galvanized for long-term resistance against the elements. The look of these S40 doors and windows can be further customized with your choice of custom glass, from glacially clear panes to privacy-enhancing finishes that block prying eyes. Our interior steel doors are crafted with precision to last a lifetime, backed by our warranty.
