What thickness of steel sheeting should be used on a horse trailer exterior?

For the exterior of a horse trailer, a steel sheeting thickness of 14 to 16 gauge (approximately 0.075 to 0.060 inches) is commonly recommended. This thickness provides a good balance between durability and weight, ensuring that the trailer can withstand the rigors of transport while remaining manageable. It's important to consider the specific design and intended use of the trailer, as heavier gauge steel may be beneficial for increased strength in high-stress areas. Always consult with a professional to determine the best material for your needs.
