Steel Frame Gauge Options

What is Galvanized Steel? 

All our buildings are constructed from galvanized steel tubing. Unlike wood, steel is not susceptible to shrinkage, and will not warp with age. It’s thanks to steel that buildings can be built more than four stories high. Our steel tubing has undergone the process of galvanization, which is the process of applying a protective zinc coating to steel, to prevent rusting. This enhances the durability of steel to another level. 

What steel gauges do you offer? 

Beforehand, it is important to clarify that all our buildings are engineer certified and meet your local codes regardless of the gauge you choose.  

Midwest Steel Carports offers two different gauge grades that have different measurements and warranties, 14 Gauge and 12 Gauge. 14 Gauge is the industry standard, nationally accepted gauge for carports, and most economical option. 12 Ga tubing you are getting a 30% thicker and 30% stronger steel tubing, higher tensile strength, and higher snow load and wind ratings.  See the comparison below: 

12 Gauge 

  • 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 think 

14 Gauge 

  • Economical Option 
  • 7 Year Warranty on Rust Through of Frame 
  • Industry Standard 
  • 2 -1/2″ x 2 -1/2″ in diameter 
  • .0747 inch thick


Which gauge do you recommend for my specific location? 

If you are purchasing with Midwest Steel Carports, you more likely located in the Midwest including the following states : Michigan, Wisconsin, Indiana, Ohio, Minnesota, and Illinois.  See the snow load chart by the International Code Council. 

If you are located in the area of 35 lb snow load or above, we highly recommend 12 Gauge. Every year snow consistently falls on top the building and having 12 gauge will withstand a longer years compared to 14 gauge. In the other areas, both options are 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.
