What is the difference between 12-gauge and 14-gauge steel?

The difference between 12-gauge and 14-gauge steel lies in their thickness and strength. 12-gauge steel is thicker and stronger than 14-gauge steel. It measures about 0.1046 inches in thickness, while 14-gauge steel measures about 0.0747 inches. As 12-gauge steel is thicker, it provides more durability and can withstand harsher weather conditions compared to 14-gauge steel.
This makes 12-gauge steel a better option for structures in areas prone to heavy snow or strong winds.
