Frequently Asked Questions
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.
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.
