Who it fits

Key specs explained

Footprint Size: 12x20 ft

This footprint provides 240 square feet of covered space. You can fit large trucks, multiple vehicles, or heavy equipment inside. The 12-foot width allows for easy side-by-side parking. The 20-foot length accommodates extended trailers or boats. This size suits buyers needing substantial storage without the cost of a full garage.

Frame Tube Diameter: 2x2 in

The 2x2 inch steel poles offer significant structural rigidity. This diameter resists bending under heavy snow or high winds better than standard 1.2x1.2 inch frames. You gain confidence in the unit's stability during storms. When comparing sheds, thicker poles indicate a heavier-duty build capable of withstanding harsh environmental conditions over time.

Frame Wall Thickness: 1.4 mm / 17-gauge

This 1.4 mm thickness provides robust protection against impact and deformation. It is notably thicker than typical 1 mm panels found in cheaper carports. You benefit from reduced vibration and a sturdier feel when closing doors. This gauge is ideal for users prioritizing long-term durability and resistance to dents from accidental impacts.

Roof Material: 0.3 mm / 30-gauge steel

The 0.3 mm roof panel supports up to 100 lbs per sq.ft. This rating ensures the structure remains intact during heavy snowfalls or hurricane-force winds. You avoid the risk of roof collapse common with thinner 0.18 mm alternatives. This spec is critical for buyers in regions with severe weather and heavy precipitation seasons.

Design and build details

The listing describes a 2x2 inch galvanized steel frame with 1.4 mm thick walls. This gauge is 40% thicker than standard 1 mm poles, offering greater rigidity for heavy loads. The roof uses 0.3 mm 30-gauge steel, which supports 100 lbs per square foot. This rating helps the structure withstand heavy snow and hurricane conditions. The design includes double-layer reinforcement with longitudinal crossbeams and top kits to prevent flexing during extreme weather.

You get an enclosed structure measuring 12 by 20 feet. The total dimensions are 143 inches wide, 230 inches long, and 102 inches high. The unit weighs 520 pounds, providing substantial mass that aids in stability. The enclosure comes in black or ash gray colors. This finish protects the metal from corrosion while matching various exterior styles. The enclosed design offers full protection for boats, trucks, or tractors from the elements.

Assembly requires three to five people and takes five to eight hours. The listing notes that this time investment ensures rock-solid stability for decades of use. Eight hurricane anchors are included to ground-lock the structure against winds over 100 mph. You can replace damaged parts by contacting support. The model number Y8L049-1220-YY22 identifies this specific 12x20 ft configuration. The design prioritizes structural integrity over quick setup, making it suitable for permanent outdoor storage needs.

Setup and everyday use

Assembly requires three to five people and takes five to eight hours. The listing notes that this timeframe ensures rock-solid stability for long-term use. You will assemble a 2x2 inch galvanized steel frame with 1.4 mm thick walls. The structure weighs 520 pounds, so handling the components demands care. The unit measures 143 inches wide, 230 inches long, and 102 inches tall. This height accommodates standard vehicles, though other height options exist for taller equipment. You must secure the carport using eight hurricane anchors. These anchors ground the structure to resist winds up to 100 mph. The double-layer reinforcement includes two longitudinal crossbeams and top reinforcement kits. This design supports extreme weather conditions, including blizzards and hurricanes. The roof uses 0.3 mm 30-gauge steel, which supports 100 lbs per sq.ft. This thickness is 67% greater than flimsy 0.18 mm panels. Daily use involves storing trucks, boats, or tractors. The enclosed design protects valuables from the elements. If parts are damaged, you can contact K Knowbody Support for instant replacements. The black finish is available in other colors like Ash Gray. You can also choose between enclosure or standard sets. The 12x20 ft footprint provides ample space for side-by-side parking or extended trailers. This setup process ensures the carport remains stable during high winds. The heavy-duty construction minimizes the need for frequent maintenance. You rely on the structural integrity provided by the galvanized steel poles. The 17-gauge walls offer rigidity against impact. This carport is built for decades of protection with proper assembly.

Before you buy this carport

You will need to prepare a solid, level foundation before assembly. The 12x20 ft footprint requires a flat surface to ensure proper drainage and structural integrity. Check local zoning laws and HOA rules, as some communities restrict metal structures or specific colors like black or ash gray. Verify that your chosen site can support the 520-pound weight of the unit itself, plus any vehicles or equipment stored inside. You should also confirm that the 102-inch height fits your clearance needs, especially if you plan to store tall items like boats or tractors. The enclosure design keeps out debris, but you will still need to clear snow from the roof periodically to maintain the 100 lbs per sq.ft rating. This unit sits alongside other storage options in 1 choices. Unlike sheds, it offers open-side access while protecting against wind and rain. Ensure you have enough space for the 8 hurricane anchors to secure the frame firmly into the ground.

Check before you buy

• Confirm local zoning allows metal carports of this size.
• Check HOA rules for approved colors like black or ash gray.
• Ensure the site is level to support the 520-pound weight.
• Verify 102-inch height clearance for your tallest stored items.
• Prepare ground for 8 hurricane anchors to secure the frame.
