Short answer: Midwest Steel offers both 14 gauge and 12 gauge as steel frame gauge options.
At Midwest Steel, we offer the 14 gauge square tubing as the standard option for your steel building. Additionally, you also have the option to upgrade to the 12 gauge square tubing for additional benefits! However, all buildings are engineer certified and meet your local codes regardless of the gauge you choose. Common questions we answer throughout this blog include what galvanized steel is and recommendations for your specific project.
What is galvanized steel?
We manufacture every Midwest Steel project with galvanized steel. Our steel tubing has undergone the process of galvanization. During this process, a protective zinc coating covers the steel to help prevent rusting. This process enhances the durability of steel to another level. Additionally, unlike wood, steel is not susceptible to shrinkage and won’t warp overtime. It’s thanks to steel that buildings can be built more than four stories high!
What steel gauges do you offer?
Midwest Steel offers two different gauge grades that have different measurements and warranties. Two different gauges include the standard 14 gauge and the upgraded 12 gauge. 14 gauge is the industry standard and is the nationally accepted gauge for carports. Additionally, 14 gauge is the most economical option for your project. On the other hand, 12 gauge tubing offers you a 30% thicker and 30% stronger steel tubing. Therefore, the 12 gauge is a higher tensile strength, with higher snow load and wind ratings.
- Economical option
- 7-year warranty on rust through of frame

- 2 1/2″ x 2 1/2″ in diameter
- .0747 inch thick
- Heavy duty option- high tensile strength
- Best for heavy snow loads and high winds
- 20-year warranty on rust through of frame
- 2 1/4″ x 2 1/4″ in diameter
- .1046 inch thick
Which gauge do you recommend for my specific location?
Below is a snow load chart by the International Code Council. If you’re in areas with a 35-pound snow load or above (lbs psf), we highly recommend 12 gauge framework. Since 12 gauge is a thicker gauge, your project can withstand harsh weather conditions longer than 14 gauge. However, areas below 35 pounds can go with 14 gauge and are still safe and structurally sound.
