Steel Frame Gauge Options

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.

12 gauge

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.

A-Frame Horizontal Roof

A-Frame Horizontal roofs give your structure a residential look. The sheet panels run from side to side and does not have purlins or ridge cap. The increase in price to upgrade to A-Frame Horizontal is the additional welding needed on your trusses (bows). An excellent option to keep your residential look for residential areas for a minimum upgrade costs.


A-Frame Vertical Roof

Known as the best choice for areas that experience extreme weather conditions, the vertical roof style is hands down the best choice for Michigan weather. The roof panels run from the pitch to the eaves causing heavy snows, rain, and natural elements to slide off the roof easily. In order to tie down the panels to the structure, we must add purlins or hat channels lengthwise making the structure more rigid. The finished look with special trim all around the roof and ridge cap makes this roof style the best option.
