In this article, we will delve into the specifics of 7 gauge steel, exploring its thickness, applications, and the reasoning behind its naming convention.
Introduction to Steel Gauges
Steel gauges are a standard way to measure the thickness of steel sheets or plates. The gauge system is inversely related to the thickness of the steel; the higher the gauge, the thinner the steel. This system is based on an older method where the thickness of steel was determined by the number of times it was passed through a rolling mill. Each pass through the mill reduced the thickness of the steel, and thus, the higher the gauge, the more times the steel had been rolled.
The Gauge System Explained
The gauge system is more complex than a simple linear progression due to its historical roots. The original method of determining gauge involved improving the uniformity and reducing the thickness of the steel through rolling. However, as manufacturing techniques improved and the need for more precise measurements arose, a standardized system was developed. Today, the gauge system is based on a specific standard that dictates the thickness of steel corresponding to each gauge number.
