What’s A Stainless Steel Gauge?

Perhaps you’ve heard this term in many stainless steel appliances. It refers to the thickness of the sheet material used in the kitchen sink construction. 

Unlike other measurements, gauge measurements are inversely proportional to the thickness of the stainless steel metal. That means that the lower the number, the thicker the gauge.

In other words, thicker stainless steel has a small gauge number, and a thinner one has a higher number. For example, an 18-gauge stainless steel sheet is thicker than a 20-gauge steel.

Most kitchen sinks have 18 or 16 gauge that is extremely heavy to withstand rust and damage.

Thin Gauges (Higher Gauge Number) 

Thin stainless steel gauges are outstanding for small kitchen sinks. Although they are prone to bowing, dings, and denting, they are highly effective and affordable for small households. 

However, sturdy pans and pots can easily damage thin gauge stainless steel sinks as they are weaker when compared to thick gauges. More so, thin gauge sinks are highly susceptible to denting and vibrating. 

As such, they are only best in small bar sinks, cabins, and recreational vehicles. For home use, we recommend using thicker stainless steel sinks. 

Thick Gauge (Smaller Gauge Number)

What gauge stainless steel sink is best for you? Well, here’s your answer: Lower-gauged or thicker stainless steel is more preferred than thin ones. This is why:                                         

  • A thicker (lower gauge) stainless steel gauge is more durable and sturdy. 
  • It’s less prone to denting and bowing.
  • It produces less noise as you undertake your daily chores 

Therefore, thick stainless steel gauges are the best for your kitchen sink, and most kitchen sinks are designed with 18 or 16 gauge thicknesses. These thicknesses are essential in terms of durability and size and are required for daily use with no dents.

Also, they are reliable, cost-effective, lightweight, and durable enough to withstand your kitchen requirements.

What Gauge Stainless Steel Sink Is Best? 18 Gauge vs. 16 Gauge 

Both 18 gauge and 16 gauge are preferred for stainless steel sinks. A 16-gauge stainless steel is approximately 0.0625-inches thick. On the other side, an 18-gauge has a thickness of 0.05 inches thick. In other words, a 16 gauge sheet steel is about 20% thicker compared to an 18 gauge.

Furthermore, it’s stronger than an 18 gauge, thus making it ideal for most homeowners. It guarantees higher usability and durability.

However, either will deliver almost the same value in terms of overall user satisfaction, cost, and performance. What varies most is the durability. And yes! You should invest in longevity. 

The difference in pricing is minimal but significant. The little bucks you spend will give you a long-lasting sink!
