W6 Beam Sizes
The W6 series runs 7 sizes, from W6x25 at 25 lb/ft to W6x8.5 at 8.5 lb/ft. They share a nominal depth and a common set of rolls, so a size change within the series usually keeps the connection detail intact.

Nominal depth is not actual depth; the tabulated d above is what to detail to.
