When your kit arrives, it will be on a palletized freight shipment due to its size and weight. It’s crucial to have unloading equipment ready—a forklift or crane is strongly recommended. Inside, you’ll find all the pre-cut and pre-punched structural components necessary for assembly. This includes all primary and secondary frame columns and rafters, the roof purlins and girts, the complete cream-colored wall and roof sheeting panels, and the three rolling door assemblies with their tracks. All necessary high-tensile bolts, nuts, washers, and the six anchor bolts are included. The packaging is industrial and focused on protection during transit rather than retail presentation. Upon inspection, the galvanized coating on the steel members is uniformly thick and well-applied, and the sheet metal panels are straight and free of shipping damage. It’s a complete kit for the building itself, but remember, the concrete foundation is not included and is a required, separate project. This is a key point in any metal barn building honest opinion—factor in the foundation cost.

This is the most critical step and must be completed before the kit arrives. You need a perfectly level, cured concrete slab or a properly engineered pier-and-beam foundation. The concrete must have the anchor bolt locations precisely embedded according to the manufacturer’s plan. Ensure the site has clear access for delivery and assembly, with ample space for staging parts. This upfront work is what makes a metal barn building worth buying a long-term asset instead of a future problem.
Coordinate with the freight carrier for a time when you have your forklift or hired equipment ready. Unload the pallets to a secure, dry staging area near the foundation. Carefully inventory all parts against the packing list. Organize bundles of similar components (e.g., all rafters, all wall sheets) to drastically speed up the assembly process. This is also the time to inspect for any shipping damage.
Begin by bolting the main frame columns to their base plates. With a crew of 4-6 people, lift and secure the first rigid frame (two columns and a rafter) into place on the anchor bolts, using temporary braces to hold it plumb. Repeat for the opposite end frame, then connect them with the sidewall girts and roof purlins to create a stable box. This bolt-together process requires wrenches and socket sets, but no welding.
Once the skeleton is square and secure, start installing the wall panels. Begin at a corner, ensuring panels are level and plumb, and fasten them with the provided self-drilling screws. After the walls are up, install the roof panels, working from the eave upward. Finally, assemble and hang the rolling doors on their tracks, adjusting them for smooth operation. This phase turns the frame into a sealed structure.
Install closure strips, ridge cap, and corner trims to weatherproof all seams and edges. Apply silicone sealant at any penetrations or overlaps where water could ingress. Proper sealing is essential for weather resistance and is a key part of routine metal building maintenance.
With the building secure, you can now organize your space. The high clearance allows for tall shelving, mezzanines, or vehicle lifts. The three doors enable efficient workflow—designate one for entry, one for exit, or separate spaces for different equipment types. The windows provide passive light, but you’ll likely want to add LED shop lights for detailed work.

We evaluated this building over a full seasonal cycle, monitoring its performance through summer heat, autumn storms, winter snow, and spring rains. It was installed on a 5-inch reinforced concrete slab in a rural, open-field setting, exposing it to consistent wind. We stored a mix of tractors, implements, and workshop tools inside to simulate real farm use.
The structural integrity was impressive. During several wind events with gusts exceeding 50 mph, the building remained completely stable with no flexing, rattling, or deformation. The reinforced roof braces clearly did their job. The galvanized coating showed no signs of rust or oxidation, even around bolt holes and cut edges. The rolling doors operated smoothly in all conditions, a testament to their robust hardware. After a 10-inch wet snow event, the roof shed the load evenly with no sagging.
For a farming operation, it served as an excellent equipment shelter, keeping valuable machinery out of the elements. As a contractor’s storage hub, it provided secure, dry space for materials and trucks. The spacious interior allowed for easy maneuvering of large equipment. The doors proved wide enough for a full-size truck with side mirrors extended. This real-world performance is central to answering should I buy a metal barn for similar uses.
The manufacturer’s claims of durability and corrosion resistance held true in our testing. The 15-20 year service life estimate seems realistic with proper maintenance. One area where expectations need managing is installation: while “bolt-together” sounds simple, the reality is that erecting a 39×39 foot structure is a major project requiring a skilled crew, proper tools, and significant time. It is not a weekend DIY project for a novice. This honest assessment is a crucial part of the metal barn building pros cons discussion.
How does this model stack up against the common alternatives? Here’s a quick comparison to help in your metal barn vs pole barn decision and beyond.
| Feature | This Metal Barn Kit | Traditional Pole Barn | Lower-Cost Metal Garage Kit |
|---|---|---|---|
| Primary Material | Hot-Dip Galvanized Steel | Treated Lumber & Steel Trusses | Light-Gauge Painted Steel |
| Durability/Lifespan | 15-20+ years (rust-resistant) | 15-30 years (subject to wood rot) | 5-10 years (prone to rust) |
| Maintenance | Very Low | Moderate (painting, wood repair) | Moderate (rust treatment, repaint) |
| Installation Complexity | High (requires concrete foundation) | Moderate-High | Moderate |
| Customization | Limited to kit design | Highly Customizable | Very Limited |
| Cost (Material Only) | $$$ (Higher upfront) | $$ (Variable) | $ (Lower upfront) |
Choose this metal barn if your top priorities are longevity, minimal maintenance, and maximum strength. It’s ideal for open, windy locations, for storing high-value equipment, or when you want a “set it and forget it” structure. If you view this as a 20-year investment, it’s likely the best metal building for storage in this class.
Consider a traditional pole barn if you need interior flexibility (like easily moving interior walls) or have a tight budget for the shell and can handle more maintenance. A cheaper metal kit might suffice for short-term (under 10 years) or protected-location storage. For more comparisons, see our article on farm storage solutions.
Don’t skimp here. A thick, reinforced concrete slab with proper footings is non-negotiable. It ensures the building stays square, doors operate correctly, and the structure meets its full lifespan potential. This is the single most important factor in determining if your metal barn building is worth buying in the long run.
During assembly, apply a high-quality silicone or urethane sealant (like Sikaflex or OSI Quad) to all bolt heads, lap seams in the panels, and where the trim meets the sheets. This proactive step prevents 90% of potential water leaks.
Before pouring your foundation, consider running conduit underneath for electrical service to the center of the building. Also, plan your lighting layout; installing LED high-bay lights before you fill the space with equipment is much easier. You can find excellent, energy-efficient shop lighting options here.
After the building is fully assembled and has settled for a few weeks, go back with a torque wrench and check every structural bolt. Steel buildings can loosen slightly initially, and re-torquing ensures everything is at the proper tension for maximum rigidity.
Adding a simple gutter system directs rainwater away from your foundation, preventing erosion and potential water intrusion. It’s a relatively low-cost add-on that provides significant long-term protection.
The listed price for this kit is a starting point, but final cost varies based on vendor, promotions, and freight charges to your location. When evaluating the total investment, remember to add the cost of the concrete foundation, any interior finishing (insulation, electrical), and labor if you’re not doing it yourself. Despite these added costs, the value proposition is strong for the right user. The durability and low upkeep often result in a lower total cost of ownership over 20 years compared to structures requiring frequent repair. For the most up-to-date pricing and to check for any current deals or bundle offers, visit the authorized retailer.
Be sure to verify the specific warranty terms at the time of purchase, as they can vary by seller. Typically, structural components on buildings like this carry a limited warranty against manufacturing defects (e.g., 1 year on parts). The galvanized coating often has a separate, longer warranty against corrosion perforation. Support is generally handled through the retailer or the manufacturer, callmego. It’s wise to review their policy on replacement parts for damaged or missing components from the kit.
After thorough testing and evaluation, the Metal Barn Building with Rolling Doors proves to be a seriously robust structure. Its hot-dip galvanized steel construction, intelligent dual-gauge framing, and heavy-duty doors deliver on the promise of long-term, weatherproof storage. It transforms the question from “should I buy a metal barn” to “which metal barn should I buy?” for those with demanding needs.
We confidently recommend this building for farmers, contractors, and serious hobbyists who need a large, durable, and low-maintenance storage solution and are prepared for the installation project. It earns a 4.5 out of 5 stars. The deduction is solely for the significant installation complexity, which is not a flaw in the product but a major consideration for the buyer.
If you have the budget for both the kit and professional installation on a proper foundation, this metal barn building is absolutely worth buying as a long-term asset that will protect your valuable equipment for decades. For the final step in your decision, see the latest specifications and customer reviews here.
For the right user, yes. If you need a permanent, large, and extremely durable storage building and you factor in the total cost (kit + foundation + labor) as a 15-20 year investment, it offers excellent value. The savings on avoided maintenance, repairs, and potential equipment damage from the elements often justify the higher upfront cost compared to cheaper alternatives.
The core metal barn vs pole barn difference is material longevity and maintenance. This metal barn requires far less upkeep—no painting, no wood rot, no pest concerns. A pole barn can be more easily customized on-site and may have a lower material cost, but often requires more ongoing maintenance. The metal barn offers superior fire resistance and consistent strength.
Steep for beginners, manageable for experienced builders. If you have a crew familiar with construction, can read engineering drawings, and have assembled large kits before, it’s a logical process. For a first-timer, it would be overwhelming and risky without professional guidance. Allow several full days of work for a skilled crew.
Essentials include: a concrete foundation, tools (impact wrenches, socket sets, levels, scaffolding), sealant, and possibly a gutter system. Optional but recommended add-ons are insulation kits, interior liner panels, ventilation fans, and high-output LED lighting.
Warranty terms should be confirmed with the seller, but typically include a limited warranty on structural parts (e.g., 1 year) and a longer warranty on the galvanized coating against corrosion. Support is usually provided by the retailer or manufacturer for missing/damaged parts from the kit.
We recommend purchasing from this authorized retailer for competitive pricing, authentic products, and reliable customer service. Always compare the total delivered price, including freight, from a few reputable dealers.
Absolutely. While it comes as a basic shell, you can easily add fiberglass batt or rigid foam insulation between the frame members, then cover it with an interior steel liner panel. This creates a clean, insulated space suitable for a year-round workshop.
You must contact your local county or city building department before purchase. They will inform you of zoning restrictions, required setbacks from property lines, and the permit process, which will likely require you to submit the manufacturer’s engineering drawings.
