Landmark175 Series Steel Windows & Doors

The Landmark175 Series introduces two hot-rolled steel sections that achieve a narrow sightline of approximately 2-3/16 inches at operable windows and doors. This narrower framing increases visible glass area and daylight penetration, enabling architects to realize more expansive views and lighter, more transparent façades without sacrificing strength or durability. The 1-3/4-inch-deep profiles accommodate glass makeups up to 1-1/8 inches, allowing a broad range of insulating, laminated, and specialty glazing options to address energy, acoustic, security, or life-safety requirements within a single unified system.
