Optimum’s Reliant Line of Steel Windows and Doors offers reliability and versatility. These characteristics are key when designing a project. These series have been used in countless applications, ranging from high-end homes to commercial and even industrial applications. One major quality associated with our units are their narrow sight lines. Architects have incorporated this attribute into all aspects of the building process for over a hundred years and have designed the seamlessness and grace of steel windows into countless architectural styles. The system’s large opening casements and slim frames make it particularly popular amongst conservationists and even planners as well. This advantage allows the use of immense glass lites, often in spectacular openings, whilst maintaining narrow sight lines. The look is not simply distinctive, it is also unique. Our steel windows and doors have been selected for use in the most contemporary of settings, as well as traditional, ranging to even Gothic structures.

No other steel window system can offer such an extensive range of sections as well as the variety of options for factory-applied-corrosion-inhibiting-finishes’ including galvanizing, E-coating (electro-coat) primer, powder coatings, urethane enamels and more. In addition, we offer countless styles of hardware options that allow the designer an opportunity to create unique custom styles.

With the narrow sight lines of Optimum’s Hot-Rolled Steel profiles, design possibilities are endless. The flexibility of this product allows for custom shapes and configurations to fit any applications, ranging from commercial to high-end residential.
