Optimum’s Fire Rated Fixed Steel Windows have been proven to withstand temperatures of 1650 F(899 C), Fusible links melt at 165 F (74 C) allowing the window to automatically seal shut, preventing spread of fire to adjacent buildings.

All principal cold rolled frame members are ASTM A528 low carbon steel, formed from a minimum of 20 gage steel, with a depth not less than 1 7/8” (48mm) with reinforced mitered corners. Corner joints are fully sealed to prevent water leakage and are then mechanically fastened. Muntins, when required, are formed “T” sections that are mechanically fastened to the perimeter frame. Intersections are crossed notched.

Windows are designed for inside glazing of specified type. Approved glass is held in a *” (19mm) uniform edge bite. Fire Rated windows are factory glazed with rated glazing such as polished or obscure wire glass. Individual glass lites are not to exceed 895sq in. as per UL requirements.

Operating ventilators have factory applied EPDM gaskets around the entire perimeter

Operating sashes are supported on stainless steel wheels that allows the sash to slide in a horizontal motion.

The overall size of the window dictates the type and quantity of sweep locks. (verify with the Optimum engineering department)

All vents on fire rated windows are designed with self-closing hardware, which is activated via a fusible link during the course of a fire.

Cold rolled steel windows are categorized as either commercial or industrial windows.

All cold rolled steel sections receive zinc coatings throughout as per ASTM A525 Z200, applied by a continuous hot dipped process (the Sendzmir system), followed by a skin pass (smoothing procedure) which eliminates roughness.

Primer consists of thermosetting epoxy- ureic paint, at a thickness of 5 microns. A finish coat of polyester powder coating is baked on at 180 to 200 degrees C for 15-20 minutes with an average thickness of 80 microns.

Windows are offered in two stock colors Brown and White as a standard. All windows can be painted in a wide range of custom colors to suite project needs, as an option.
