OS-TEC 50/60/80 -1 TB


Steel | Cor-ten Steel | Stainless Steel

OS-TEC stands for a family of glass fixing components for custom steel curtain walls with sightlines of 50, 60 and 80 mm. OS-TEC’s glass fixing systems offer exceptional acoustic and thermal insulation and can be connected to any type of steel mullion or transom like solid T-shapes or rectangular hollow sections. Next to these standard designs, OTTOSTUMM offers free form mullions and transoms as the ultimate step in customized steel façades. For architecturally exposed steel projects, laser welded profiles are the answer. No other technology allows unfolding custom design on steel, cor-ten steel or stainless steel curtain walls like laser welding. Mullions of 15 m (49 ft) length and up to 500 mm (20”) depth determine the range where architects can express their creativity. All profiles have sharp crisp corners, clean shadow lines and smooth almost invisible weld seams.
