What is gauge

Gauge is the measurement unit for thickens of metals. The smaller the gauge the thicker

the metal.  For example, 16 gauge stainless steel sinks are thicker than 18 gauge

stainless steel sinks which in turn more durable and rigid.

There are sellers out there claiming their sinks are made of 15 gauge stainless steel, please beware

that there is NO 15 gauge stainless steel in this world because metalworking companies don't fabricate 

odd numbered stainless steel sheet metal.  It is absolutely false advertising if any companies claim their

stainless steel sinks are 15 gauge in thickness.
