Thicker stronger steel for the all-important building envelope-an integral part of your building’s engineering design

Our standard steel gauge is 29 gauge but Pole Building Supplies also offers a 26 gauge panel which is THICKER, HEAVIER and STRONGER!

The thicker metal is…

  • Less susceptible to hail damage and dents
  • Less purlin “show-through” on sides and roof

Why does the thickness of steel get smaller as the thickness/gauge increases?

The explanation comes from the original development of a gauge measurement system in which the control measurement was based on 1″ thick steel plate. From this base thickness, the steel was measured in diminishing fractions such as 1/14″, 1/16″, 1/20″ and so on. The bottom number of the fraction was adopted as the “gauge” and so 1/16″ became 16 gauge, 1/20″ became 20 gauge.

The concept makes sense but without explanation, it can be confusing. If you take the gauge number and return it back to a fractional format, one can discover the actual nominal thickness dimension, in inches, of sheet steel.
