Steel Frames
From the classic S20 to the technologically advanced S50 and S75, we offer Swiss-made steel systems to meet all design aesthetics. While the S20 is ideal for interior partitions or exterior windows and doors in Mediterranean climates, the thermally broken S50 and S75 are designed for everything else. With proper care, steel frames will last indefinitely.
