Technical Glass Products' SteelBuilt Curtainwall™ Systems are strong and slim, allowing for larger spans of glazing than traditional aluminum framing. The steel framing members have substantially lower deflection than aluminum, providing three times the wind-load capacity, and the lower thermal expansion of steel allows for greater design flexibility. As a result, building occupants gain the benefits of more natural light coming into a facility. TECHNICAL GLASS PRODUCTS • SNOQUALMIE, WA
