Planning and Installing Your 12×20 Metal Building
A 12×20 metal building is one of the quickest and easiest structures to assemble—perfect for DIYers or property owners on a tight timeline. With proper site prep and a small crew, installation can often be completed in a day or two. Steel offers a durable, low-maintenance alternative to wood, and upgrades like insulation or extra doors are easy to add. Just remember to check your local zoning laws and secure a building permit before starting your project—our team provides engineered drawings and location-specific guidance to help you every step of the way.
How long does it take to build a 12x20 metal structure?
A 12×20 metal building can typically be erected in one to two days, depending on how many people are on the crew and the condition of the site. For example, a team of three experienced workers may complete assembly in as little as six hours. However, don’t forget to account for site preparation and foundation work, which can take 1 to 3 weeks before construction even begins.
What materials are used in a 12x20 steel building?
Our 12×20 kits are made from galvanized structural steel, not aluminum. Steel is preferred because it offers superior strength, resists dents and corrosion, and holds up better in harsh Canadian weather.
Can a 12x20 metal building be insulated?
Yes—this size is ideal for insulation upgrades. Common insulation methods include spray foam, fiberglass batts, double bubble wrap, foam boards, or woven reflective insulation, all of which help regulate temperature and prevent moisture build-up.
Do I need a permit to install a 12x20 steel building?
In most areas, yes. You’ll need to meet your municipality’s zoning regulations and apply for a building permit. Our kits come with stamped engineered drawings to help you through the process and ensure compliance with local wind and snow load requirements.
What kind of crew is needed to install a 12x20 building?
For a 12×20 size, a two- to three-person crew with metal building experience is usually enough. Basic lifting equipment, hand tools, and OSHA-compliant safety gear are required. While DIY is possible for seasoned builders, hiring a certified erection crew ensures a faster, safer, and smoother experience.
