This k knowbody military grade 13x20 ft metal review covers a substantial outdoor structure designed for serious storage. The unit offers 260 square feet of interior space, defined by its 13 by 20 foot footprint and an 8-foot peak height. It is constructed from 23-gauge galvanized steel with a reinforced 18-gauge internal truss system. These two specs establish its capacity and structural integrity. The building kit includes double front doors and a side entry, providing flexible access for vehicles or large equipment. It is intended for permanent outdoor installation.
What stands out
- 23-gauge galvanized steel exterior panels resist weather and corrosion.
- 18-gauge double-reinforced internal truss and beam system for added strength.
- 4 transparent polycarbonate skylight panels provide natural interior lighting.
- Dual-entry design with lockable double front doors and a separate side door.
- Ventilation channels in the steel frame floor kit help resist humidity.
Who it fits
Good fit for
You should consider this shed if you need a large, permanent structure for a car, boat, or workshop. The 260-square-foot interior and 8-foot height accommodate full-size vehicles and tall equipment. The reinforced steel frame suits areas with high wind or heavy snow loads. Buyers who want natural light for projects will appreciate the skylights. The dual-door setup is ideal for those who need both vehicle access and quick walk-in entry for tools.
Who should skip it
Skip this option if you cannot install a concrete foundation or purchase heavy-duty auger anchors. The manufacturer strongly recommends permanent securing for stability, especially on soft surfaces like dirt or gravel. You must buy anchors separately if not using concrete. Also, avoid this kit if you prefer a quick solo assembly, as it requires three to five people. The 580-pound weight and complex frame make it unsuitable for temporary or easily movable storage solutions.
Verdict: This shed is a robust, high-capacity storage solution for buyers who can commit to a permanent foundation and multi-person assembly. Its reinforced steel construction and dual-entry design make it suitable for heavy-duty outdoor use.
Key specs explained
Footprint Size: 13 x 20 ft
This measurement defines the ground area the shed occupies. You get 260 square feet of interior space, which is large enough to park a car or boat. This footprint is ideal if you need a full-size garage alternative. When shopping, compare this to smaller 8x10 sheds to ensure your yard has enough clearance for this substantial structure.
Material: 23 gauge galvanized steel
The walls are built from 23-gauge galvanized steel. In metal thickness, a higher gauge number means a thinner sheet. This 23-gauge steel provides a solid barrier against wind and rain while resisting rust. It is suitable for storing tools and equipment. Compare this gauge to lighter 29-gauge options found in cheaper sheds to see the difference in durability.
Roof Style: 8 ft peak, 4 skylight panels
The roof reaches an 8-foot peak height, offering ample headroom inside. The four transparent polycarbonate skylight panels allow natural light to enter during the day. This reduces the need for artificial lighting and creates a brighter workspace. When comparing sheds, look for similar skylight counts to ensure you get adequate illumination for working on projects inside.
Door Type: Double front door, side door
You get two entry points: a wide double front door and a separate side door. The front door allows easy access for large items like lawn mowers or vehicles. The side door provides quick walk-in access without opening the main entrance. This dual-entry design is convenient for workshops. Compare this to sheds with only a single door for better workflow.
Assembly: 3-5 person project
The manufacturer recommends three to five people for the build. This structure weighs 580 pounds and includes many pre-drilled panels and a steel frame. Having extra help ensures safety and speeds up the process. You will need helpers to lift heavy sections and align the frame. Compare this requirement to smaller sheds that may only need two people to assemble.
Design and Build Details
The structure uses 23-gauge galvanized steel for the exterior panels and an 18-gauge internal truss and beam system. According to the listing, this reinforced framework helps the shed withstand wind speeds up to 150 mph and heavy snow loads of 50 to 100 PSF. The material choice suggests a focus on durability in harsh weather conditions rather than aesthetic appeal. The exterior is finished in blue-black, a color that may help hide dust or minor scuffs over time. The entire kit weighs 580 pounds, indicating a substantial amount of metal used in its construction.
The footprint measures 13 by 20 feet, providing 260 square feet of interior space. The overall dimensions are 151 inches wide, 237 inches long, and 100 inches high, including the floor frame. This size accommodates vehicles like cars or boats, as well as extensive lawn equipment. The layout features wide-swinging double front doors for large item access and a separate lockable side door for quick entry. You also get four transparent polycarbonate skylight panels and four ventilation windows. These features allow natural light and airflow, reducing moisture buildup inside the structure. The design prioritizes utility and security, with included anti-theft locks on both doors. You must secure the shed using the included ground anchors or purchase separate auger anchors for soft surfaces to ensure stability.
Setup and everyday use
You need three to five people to assemble this structure. The kit includes pre-drilled panels, a full steel frame, skylights, windows, and a ground anchor kit. You also receive a detailed manual with a step-by-step installation video. The listing strongly recommends building a concrete foundation for maximum stability. You must use the included anchors to secure the shed permanently. If you install the unit on dirt, soil, or gravel, you need separate heavy-duty auger anchors. These anchors should be at least 30 to 36 inches long to grip deep into the ground below the frost line. The steel frame floor kit installs after the main structure is assembled. This base creates space between the ground and your floor. It features ventilation channels to resist humidity and supports up to 250 pounds per square foot. This setup is necessary for lawn equipment and heavy tools. Daily use is defined by the dual-entry design. A wide, lockable front double door allows easy access for large items like cars or boats. A separate, lockable side door offers quick walk-in entry. The interior is lit by four transparent polycarbonate skylight panels. Four ventilation windows ensure constant airflow. This combination prevents moisture and mustiness. The 8-foot peak height and wide doors make it suitable for a workshop or garage. You can organize tools without compromise. The structure is designed for outdoor use in all weather conditions.
Before You Buy This Shed
This structure requires significant preparation before installation. The listing strongly advises a concrete foundation for maximum stability. If you choose dirt or gravel, you must purchase separate heavy-duty auger anchors, ideally 30 to 36 inches long, to grip below the frost line. The steel frame floor kit adds height and ventilation but must be installed after assembly. You also need to verify local zoning laws and permit requirements for a building of this size. The 23-gauge steel and 18-gauge truss system offer durability, but you should inspect the polycarbonate skylights for cracks during assembly. Regular maintenance includes checking sealants around the windows and doors to prevent moisture intrusion. This model fits users needing large, permanent storage. It differs from smaller, portable options by its fixed nature and heavy material weight. Ensure you have adequate space for the 13 by 20 foot footprint and the additional height of the base kit.
Check before you buy
- Confirm local zoning laws allow a 13x20 ft structure
- Prepare a concrete foundation or buy 36-inch auger anchors
- Verify you have three to five people for assembly
- Check that your site has room for the base kit
