At Strictly Sinks every ½" Radius Sink is hand-crafted from 304 16 Gauge Stainless Steel, which offers superior surface protection from scratching, staining and rusting. Equally important, the finish is done through a process called vapor deposition. Vapor deposition is a molecular bond between metals that binds the surface and materials used at their respected atomic levels. This is NOT a simple process and requires the expertise of highly qualified engineers and physicists. It's safe to say you'll love your ½" Radius Sink. In fact, look closely at the texture and you'll see just how well it will go with your design. The surface offers antibacterial defense which as a result, keeps your family safe from germs.
