Optimum has been providing Cold Rolled Steel Windows with great success due to it’s cost, performance, and reliability to commercial and residential installations worldwide.

Frame:

All principal cold rolled frame members are either

• ASTM A528 low carbon Steel
• OT67 Bronze Alloy
• .314 brushed Stainless Steel formed from a minimum of 18 gage, with a depth not less than 2 *” (57mm) with reinforced mitered corners. Corner joints are fully sealed to prevent water leakage and are then mechanically fastened( welded corner assembly is available as an option). Muntins, when required, are formed “T” sections that are mechanically fastened to the perimeter frame. Intersections are crossed notched.

Glazing:

Windows are designed for interior or exterior glazing of specified type. Approved glass is held in a *” (19mm) uniform edge bite. Window is designed to receive glass from 1/4” to 1 1/4” overall thickness.

Weather stripping:

Operating ventilators have factory applied EPDM gaskets around the entire perimeter.

Hardware:

Operating vents are on supported on stainless steel arms. The overall size of the window dictates the type and quantity of sweep locks. (verify with the Optimum engineering department)

Finishes:

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.

Coating thickness:

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.

Colors:

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.
