Frequently Asked Questions
Q. "What is the difference between an 'under counter' kitchen sink and a 'self rimming' sink?"
A. An "under counter" sink is just that - it mounts from the bottom of the counter. A self-rimming sink has overall dimensions larger than the opening i the counter and sits on top of the countertop.
It requires no additional rim around the outside of the sink, and generally will give you a lot less problems down the road. Why? Because it cannot fall down and gravity over time will not open the seal between the counter and the
sink with a self rimming sink. Undercounter mounts can be used with solid surface or granite, marble counter tops. If you're using Formica type counters use the self-rimming. For tile we like to recommend self rimming. Under counter
sinks, over time can have problems where the sink and counter meet.
Q. "What is StoneGuard™?"
™ is a sprayed on powered coating for the underneath of your sink. It provides your luxury sink with extra sound absorption for a quiet operation.
Q. "Please explain the best gauge of stainless and which is longer lasting?"
A. The lower the number, the thicker the material. In our opinion, 22 gauge is bare minimum - builder quality. During the manufacturing process, stainless steel sinks are "stamped" into shape. That means
that the material stretches and therefore the corners can be very thin. We suggest at least 20 gauge and preferably 18 gauge.
Q. "What do the different types of stainless steel (304, 316, etc) mean?"
A. The term "stainless steel" refers to specific grades of steel that contain more than 10% chromium. Stainless steel may also include a variety of other elements (such as nickel, titanium, molybdenum, etc);
it resists corrosion and is generally a stronger, more reliable steel. The most common grades of stainless steel are:
Type 304: Aside from having a higher content of chromium than most other types of stainless steel, type 304 also contains nickel; this enables it to withstand most ordinary corrosion in architecture, is durable in typical food
processing environments, and resists most chemicals.
Type 316: Similar to type 304, but also contains a small amount of molybdenum, which is an alloy element #304 does not contain (but one that provides even stronger resistance to some deterioration). Types 304 and 316 are grades
of stainless steel that are most often used in plumbing, as well as in the manufacturing of kitchen utensils and sinks.
Type 409: Does not contain virtually any nickel at all, but also is the stainless steel that contains the least amount of chromium. Type 409 is more suitable for high temperature applications, which is why it's often used in
automotive trim and exhaust systems, or hot water tanks.
Type 410: Also does not contain any significant nickel; its primary difference to type 409 stainless is characterized by the use of heat treatment for hardening and strengthening. Type 410 is not appropriate for severely corrosive
applications, but used instead in environments that require high strength; this is why it's the type of stainless steel that's often used in surgical equipment.
Type 430: Another plain-chromium stainless steel, similar to type 409, but is usually used in decorative applications.
