CERTIFIED EXPERIENCE
With the United team’s combined 20 years of working in the steel carports industry, we blend unmatched trade knowledge with excellent customer service for the best buying experience for metal buildings and carports in the nation.

Our knowledgeable building specialists ask the right questions to determine the exact customized structure that each customer needs. We sell better quality materials by thoroughly vetting any manufacturer or installer before deciding to work with them, thereby helping small businesses create jobs in the process.

​COMMON SENSE PRICING
Unlike some companies that try to jack up the price of your carport by inflating the cost of installation, United Metal Structures includes the cost of installation in the price of each building. Yes, that’s right, we provide FREE INSTALLATION!

So, the estimate you get is the price you’ll pay.
​

Our professional sales team works hard to get you the best price on the right structure for your project, working with our manufacturer partners to find and build the most reliable and affordable products.
