Most options are made from 304 / SUS304 stainless steel. Some listings call out thicker panels or tabletops, for example a 3 mm upgraded panel and a 2 mm thickened tabletop, and one sink specifies 16-gauge T-304 construction.
Most listings show a 1 Year Limited Warranty, while at least one listing specifies a 3 Month Limited Warranty.
Listings show undermount and drop-in (dual/dual-install) styles. At least one listing is described as an apron-front (farmhouse) workstation sink.
Several listings note a standard drain opening compatible with garbage disposals; one listing explicitly specifies a 3.5" drain opening.
Several listings call out rounded inside corners (listed as R10 or 10 mm) and sloped or X-shaped bottoms, plus noise-dampening pads to aid drainage and reduce noise.
Some listings provide cutout dimensions and minimum base cabinet sizes. For example, a 32" model shows a 30.0 x 16.0 in cutout with a 36" minimum base cabinet, while a 30" model lists a 28.0 x 16.0 in cutout with a 33" minimum base cabinet.
