The W20 series of steel window sections is the most popular and diverse steel framing system available. The system not only offers the thinnest possible sightlines but also offers significant strength allowing it to be used for multi-light and curtain wall assemblies.
The SMW series of steel window sections are the oldest steel window sections currently available. Used extensively throughout the last century, the section is commonly associated as the classic steel window seen on 1000’s buildings nationwide. Unlike other manufacturers we still use the original un-modified sections to maintain the slim site-lines, enabling us to offer double glazed replica windows that can be used within existing apertures without any modification works.
