Three-Car Metal Garages
Maximum space for multi-vehicle households, serious hobbyists, and home-based businesses. Our three-car metal garages deliver warehouse-level durability with residential flexibility — all at a fraction of traditional construction costs.
Why Choose Three-Car Steel Garages?
When two bays aren't enough, a three-car metal garage gives you the room to park, work, and store without compromise. Ranging from 28' to 40' wide and up to 60' long, these buildings offer spacious open interiors perfect for three or more vehicles, a dedicated workshop, home gym, or combination of uses. Built with the same commercial-grade steel as our smaller garages, three-car models add serious square footage to your property at a cost that makes stick-built construction look unreasonable.
Three-car metal garages are the go-to choice for car enthusiasts, contractors, hobbyists, and families who need serious space. With widths up to 40 feet, you can park three vehicles comfortably or dedicate entire bays to workshops, studios, or storage. Many of our customers use the third bay as a flex space — seasonal vehicle storage in winter, a workshop in summer, or a permanent home business.
