Wire Gauge Chart UK

Michael Holt | Technical Information

I need a Wire Gauge Chart relevant for the UK, no problemo...but first

What is Gauge when people are using it reference to steel work?

In the context of steel work, the term "gauge" typically refers to the thickness or diameter of the steel. The thickness of steel sheets or wires is often specified using a gauge number. There are different gauge systems, and the choice of system depends on the region or industry. Two common gauge systems for steel are the Standard Gauge (also known as the Birmingham or Stubs Iron Wire Gauge) and the American Wire Gauge (AWG).

1.            Standard Gauge (Birmingham or Stubs Iron Wire Gauge):

  • The Standard Gauge is a system that originated in the United Kingdom.
  • It assigns a gauge number to different thicknesses of wire or sheet metal.
  • In this system, a higher gauge number corresponds to a thinner material.

2.            American Wire Gauge (AWG):

  • The American Wire Gauge is commonly used in North America for specifying the diameter of electrical wire.
  • It is also used for some other applications, including steel sheets.
  • In the AWG system, a lower gauge number indicates a thicker wire or sheet.

For example, in the Standard Gauge system, a sheet with a gauge of 16 is thicker than a sheet with a gauge of 20. In the AWG system, a wire with a gauge of 10 is thicker than a wire with a gauge of 20.

It's important to note that different industries and regions may use different gauge systems, so it's crucial to be aware of the specific system being referenced in each context. Additionally, in some cases, thickness may be specified in inches or millimeters instead of, or in addition to, gauge numbers.

It is common with Tube Inserts to reference a gauge range i.e 14-20 gauge would be referencing 1-2mm
