Aluminum - Tee Angle Arch. - 6063-T52 Architectural TEE-angle
6063 is often called architectural aluminum for two reasons: first, it has a surface finish that is far smoother than the other commercially available alloys; and second, its strength is significantly less, (roughly half the strength of 6061), making it better suited for applications where strength is not the foremost consideration. STANDARD STOCK LENGTHS ARE 16 ft (192")
