Push the boundaries of design with TGP’s steel curtain wall systems. The high-end solution utilizes the superior strength of steel, allowing for larger glazed areas, smaller frames and greater free spans.


With strength and aesthetics that exceed conventional aluminum assemblies, TGP’s advanced steel curtain wall systems help design professionals take curtain walls to new heights. Not only do they allow for greater free spans of glazing than traditional aluminum framing, but with more glass and less framing, they also improve sight lines and daylight transfer. Better yet, with watertight framing joints, exceptional thermal performance and three times the wind load capacity of aluminum systems, performance is second to none. See how TGP’s SteelBuilt Curtainwall® Systems elevate captured and non-captured curtain wall system design.
