LS Series Doors are designed and built to withstand the harshest environments. This solution utilizes all-stainless-steel construction, including reinforcement components and anchors. LS Series Doors are available in either 304 or 316 alloy for maximum durability and corrosion protection. Stainless steel stiffeners are epoxy-glued to eliminate surface imperfections associated with welding.

In addition to standard flush and panel doors, custom doors are available in a wide range of polished, embossed, and etched finishes. Custom sizing, lites, and finishes combined with industry performance ratings can create an architectural design perfect for showcase projects.
