Product Technologies and Benefits:

• Extra Thick, 16 Gauge Stainless Steel: Short of paying thousands of dollars, 16 gauge is as thick as sinks come (22% thicker than 18 gauge; 36% thicker than 20 gauge). Thicker steel means a stronger sink (hence the lifetime warranty) while also offering a richer and more robust appearance to the finish that is easily discernible from the white-washed, cheap look of thinner sinks.
• Premium Grade T-304 Stainless Steel: There are two primary types of stainless steel in the market: T-409 and the higher quality T-304. The difference lies in chromium and nickel contents; T-409 with 11% and .5% respectively, T-304 with 18% and 10%. When added to steel, these two metals prevent oxidation and rust by neutralizing sodium chloride (salt) – a common element in everyday kitchens. While cheaper sinks use T-409, Kraus sinks boast T-304, further lending to the lifetime warranty.
• Sound Insulated: Sound insulated steel is commonly only thought of in the automobile industry. There, auto manufacturers use spray-on “Stone Guard” insulation to provide for a quieter ride and protect the steel. Borrowing this technology and adding to it, Kraus sinks use Stone Guard insulation, sprayed over rubber sound dampening pads to create a noticeably lower-tone and overall quieter kitchen sink. It also protects your cabinet from underside condensation drips.
• Included Dish Grids (Basin Racks) and Basket Strainers (Drains): It’s a wonder why dish grids aren’t included with all sinks; they serve a valuable role. Not only do they virtually eliminate scratches, they allow the sink to properly drain, preventing sink scum and protecting your cutlery. As with most Kraus kitchen sinks, this sink includes the stainless steel sink grids along with the basket strainers you’ll need for installation.
• Heavily Certified: Kraus has gone to great lengths to be able to provide you, the homeowner, the rest-easy satisfaction knowing that your sink is certified and listed by all the major product testing boards in the U.S. and Canada. This means that this sink is deemed safe to use and that it meets all applicable building codes. Certifications and listings include: UPC, cUPC, CSA, IAPMO, ANSI and SCC.

Advantages of Stainless Steel over Enameled Cast Iron or Fireclay:

• Very durable; will never chip or crack
• Dishes usually don't break when dropped during dish-washing
• Due to relative weights, stainless steel is generally much easier (and less expensive) to install
• Nonporous; resists bacteria
• Neutral color fits into almost any décor - matches stainless steel appliances
