Metal Buildings
Carports and garages both protect your vehicles, but they differ in structure, cost, and functionality. Learn when to choose each option and what factors matter most.
Understanding the Core Difference At its simplest, the difference between a metal carport and a metal garage comes down to enclosure. A carport is an open or partially open structure that provides overhead protection — typically a roof supported by legs with no walls, or walls on one or two sides. A metal garage, by contrast, is a fully enclosed structure with walls on all four sides, at least one garage door, and often a walk-in door. Both are built from the same galvanized steel framing and panels, and both can be customized in a wide range of sizes, roof styles, and colors. The decision between them depends on your priorities: budget, level of protection, security, and intended use. Cost Comparison: What to Expect Carports are significantly less expensive than garages of the same footprint. Because a carport uses fewer panels, no doors, and less labor to install, you can expect to save 30% to 50% compared to a fully enclosed garage. A standard 20x21 carport might start under $2,500, while a fully enclosed 20x21 garage with a roll-up door could run $5,000 or more depending on options. If budget is your primary concern and you simply need overhead protection from sun, rain, and…
