Pick the perfect sink for your kitchen, bar & vanity

When you go shopping for stainless sinks, you will hear or see “18 gauge” and “18/10″ are mentioned together and you may be confused by the number 18 in both. OK, let’s make it clear this time…

GAUGE NUMBER

Basically GAUGE refers to the thickness of the stainless steel sheet used for the fabricating of sinks. It has nothing to do with the chromium/nickel contents in the stainless steel.

Technically speaking, the gauge number refers to the number of times the stainless steel sheet has to go through a series of narrow gaps. Each subsequent gap is smaller. So a lower gauge number means the sheet is thicker.

Typically 18 gauge is used to fabricate most standard sinks. 16 gauge or lower is used for square or apron-front sinks. 20 gauge is often used for small bar sinks which does not require a thick material to stay strong enough.

CHROMIUM/NICKEL CONTENTS

Chromium/nickel contents are mentioned almost always together. 18/10 steel means that chromium content is about 18% and nickel about 10%, which is usually the case for T304 steel that is used for almost all the sinks out there on the market. The chromium content controls the lustre, durability and corrosion protection properties of the steel, while the nickel content affects the hardness and strength of the steel.

Note that T304 steel is surgical grade which should last a life time if you do not intentionally subject the steel to harsh chemicals for a prolonged time.
