Stainless Steel Guide

Mar 1st 2018

  • Stainless steel is one of the most important components of many commercial restaurant equipment and supply units. It is paramount to this industry. Understanding grading and labels are important when deciding what models to invest in.

304 Stainless Steel
  • Higher shine.
  • Heavier duty steel than 430.
  • Less likely to rust.
  • Can withstand corrosive elements found in cleaning products, and acidic foods (found in fruits, meats and dairy and such).
  • Often used in standard and premium sinks, tables.

Note: The gauge of the stainless steel and the type of edge the table has will vary the price point.

430 Stainless Steel
  • Gray in color.
  • Less expensive due to the smaller amount of nickel used to produce it.
  • Prone to rust and discoloration, however shine will return when product is cleaned properly.
  • Often used in super saver model sinks and tables.

Note: Price points are more economical.

Stainless Steel Gauges
  • The gauge measurement refers to the thickness of the sheet metal used to make that unit.
  • Measured numerically.

Note: As the number increases, the thickness decreases. For example: a 14 gauge table is thicker than a 16 gauge table.

Galvanized Steel
  • Looks darker and rougher than stainless steel, and won't have the same polished or brushed finish look as stainless steel.
  • A zinc coating seals and protects the steel.
  • It is fairly rust-resistant, but will corrode and show wear and tear over time.
  • Cost of units are less than stainless steel.

Note: Health codes vary, please check with your local department for regulations regarding the use of galvanized vs. stainless steel.

The Numbers
18/0, 18/8 and 18/10 stainless steel
  • First number = amount of chromium contained in the stainless, so 18 is 18% chromium.
  • Second number = amount of nickel, so, 8 stands for 8% nickel.
  • 18/8 stainless steel is 18% chromium and 8% nickel.
  • 18/10 is 18% chromium and 10% nickel.

Note: Higher the number, the more corrosion resistant the material.

300 series vs. 400 series
  • When there is zero (0) nickel, the stainless grade family is of the “400 series”. (The material will be magnetic, but not as corrosion resistant as the 300 series.)
  • When there is nickel in the make-up of the stainless steel, it is part of the “300 series” stainless. (It will not be magnetic, but is more corrosion resistant.)

Note: Stainless flatware made of 18/8 will not catch in a magnetic flatware catcher. The less durable 18/0 will catch since it is magnetic.
