Frequently Asked Questions

How much does it cost to build a carport?

The cost of a steel carport depends on a few factors; first, the size of the carport package. Larger structures cost more but are cheaper when considering cost per square foot. Second, prices are determined by carport type, including the custom features that you select. Lastly, the price of steel at any time can fluctuate based on market performance. These factors combine to set your final price.

What’s the difference between a hardware store carport and a General Steel carport?

Carports from big-box hardware stores like Home Depot are designed for temporary use. Steel I-beam structures from General Steel are long-term investments that are designed that consider local weather events and conditions.

Why are steel carports superior?

Steel construction provides the strength, durablity, and value that other types of construction can’t match.
