Frequently Asked Questions

What are the typical delivery timelines?

Our I-beam buildings and carports can are typically delivered within 6-8 weeks assuming you release the structure for fabrication in a timely manner. Please check with your representative at General Steel for current timelines.

How do I anchor the carport?

Our carports can be bolted into any concrete or asphalt surface. Therefore, you can either pour a slab or in the event that you already own a hard parking surface, you can bolt and erect the carport over an existing concrete or asphalt parking lot.

What colors are available?

Visit our color schemes page as well as our photo gallery to see the most popular color combinations. Keep in mind, you will only be adding color to the roof and trim.
