Your Trusted Metal Building Supplier & Contractor
A New Hampshire metal garage gives you secure, low-maintenance space for vehicles, tools and projects. Steel framing handles heavy snow, freezing temperatures and spring moisture far better than a typical wood-framed garage. As a result, your investment keeps performing year after year.
At Maine Metal Buildings, we design and supply custom steel garages and workshops for homeowners across the state. Also, as part of our full line of New Hampshire metal buildings, every garage is engineered for the site it will stand on, not pulled from a one-size-fits-all catalog.
Unlike steel, wood garages can rot, warp and attract pests. In contrast, steel will not rot, and pre-engineered components go up faster than conventional framing. Consequently, you spend less time on construction and less money on upkeep over the life of the building.
Clear-span steel framing also means fewer interior posts. Because of that, you get open floor space to park, store a boat or set up a full workshop without working around columns.
For example, some customers need a simple one-car garage. Others, however, want a multi-bay shop with a tall door for an RV, a loft for storage, or a heated workshop for year-round projects. We work through the details with you, including dimensions, door sizes and placement, windows, insulation, roof style and exterior colors.
Because every building is custom, you can also plan for the future. For example, the frame can be designed so you can add a lean-to or extra bays later.
Snow loads vary widely across New Hampshire, from the Seacoast to the White Mountains. That is why our New Hampshire metal garages are engineered by the manufacturer for the structural load and code requirements of each specific location. As a result, you get a building designed for your town, not a generic average.
Insulation matters too. In addition, a properly insulated steel garage holds heat well, reduces condensation and stays comfortable for winter projects. Learn more about our energy upgrades for metal buildings.
Metal garages need far less upkeep than wood. For instance, there is no rot to repair and no siding to repaint every few years. Over time, those savings add up, which makes a steel garage one of the smartest long-term investments for your property.
We supply metal garages and workshops throughout New Hampshire, including Manchester, Portsmouth, Nashua, Concord and rural properties across the state. Planning something bigger? See our agricultural metal buildings and commercial metal buildings in New Hampshire.
