Architectural Frames

TGP’s architectural framing allows design professionals to create dramatic curtain walls or sleek window and door systems utilizing the strength of steel. With narrow profiles and greater free spans, the high performing framing solutions transfer ample daylight into spaces, improve wayfinding and open up views.

Architectural Framing Solutions

TGP's steel framing systems are as strong as they are versatile. The high-performance architectural framing solutions utilize advanced material forming methodologies pioneered in Europe. They outperform traditional aluminum framing with respect to allowable free spans, narrow sightlines, thermal conductivity and design flexibility.

TGP's steel frames are precision engineered using roll-forming techniques. The resulting frames are narrow, have well-defined edges (rather than rounded profiles), and have vertical-to-horizontal framing joints without visible weld beads or fasteners. The frames are available in stainless steel or can be powder coated to better match surrounding curtain wall, window or door applications.
