The actual thickness of the steel sheet is indicated as a unit of measurement referred to as “gauge.” The rating for steel gauge may seem backward:the smaller the number, the thicker the steel. For example, 14-gauge will be thicker than 16-gauge.We use a variety of different gauges on our products. However, the vast majority of our products use 14-gauge American steel for steel framing and steel tubing. We then use thicker gauges of steel such as 10-gauge or 3-gauge in steel posts, steel mesh, and other components. Rest assured, your American Stalls equipment is built to last.
