Metal Carport 12x20 ft – 100 MPH Wind Rated, 35 PSF Snow Load, Galvanized Steel, 10 Anchors | Car, Truck & Boat Shelter

12x20 Metal Carport — 240 Sq Ft of Weather-Rated Vehicle Coverage

A carport that fails in the first windstorm is worse than no carport at all — it damages what it was supposed to protect. This 12×20 ft metal carport is built to specific structural standards: a 100 MPH wind rating and 35 PSF snow load capacity. Those numbers tell you whether the structure is still standing after a winter storm or a summer downburst, and whether your truck, boat, or RV is still undamaged underneath it.

100 MPH Wind Rating + 35 PSF Snow Load

Most carport listings use words like "heavy-duty" without publishing the engineering specs behind them. Here's what this one is actually rated to handle:

• 💨 Wind: 100 MPH — equivalent to a Category 2 hurricane or a severe thunderstorm downburst, covering the extreme wind events seen across most of the continental US
• ❄️ Snow load: 35 PSF (pounds per square foot) — at 12×20 ft, that's roughly 8,400 lbs of accumulated snow before the structure reaches its design limit, well above most residential snowfall events even in heavy-snow regions

These ratings are why this carport costs more than a frame-and-tarp shelter — and why it's still standing in year three when those aren't.

Galvanized Steel Construction

The frame is reinforced square steel tubing, and the roof is galvanized steel — a coating process that embeds zinc into the metal surface to resist rust from the inside out, not a surface layer that chips and fails. Galvanized steel holds up through the humidity, freeze-thaw cycling, and UV exposure of year-round outdoor use, so the structure you install today should perform the same in year five and year ten.

Vertical Stripe Roof — Water Drains Off, Not In

The roof's vertical stripe panel design channels rainwater and snowmelt toward the edges and off the structure instead of pooling at the center or tracking along seams. Combined with the press-seam installation system, which creates watertight joints between panels, the roof sheds water rather than absorbing it — no drips onto your vehicle, no standing water accelerating panel wear.

6 Corner Supports + 10 Anchor Kits

The frame uses six corner supports — two more bracing points than a standard four-corner structure — which meaningfully improves resistance to the lateral racking forces that cause carports to lean and eventually fail in high wind. The 10 included heavy-duty anchor kits secure the structure to grass, asphalt, or concrete. Most carports ship with 4–6 anchors; 10 anchor points means every leg and intermediate support can be properly secured to the ground.

8.7 ft Interior Height

At 8.7 feet of clearance, this carport fits full-size pickup trucks, most SUVs, enclosed cargo trailers, and standard boat trailers without modifying the structure or the vehicle. The 12×20 ft footprint holds one full-size vehicle with room to walk around it, or two smaller vehicles parked in tandem.

Assembly: Labeled Parts, Included Hardware

The adaptive-screw tube frame system uses clearly labeled components and included hardware — no sourcing your own fasteners, no guessing at an unlabeled parts diagram. It's built for two people to assemble over a day, not a professional install crew, and all tools required are included.

Pro tip: in states with HOA or zoning requirements for carport structures, the documented engineering ratings (100 MPH wind / 35 PSF snow) are often exactly what's required for permit approval. Request the manufacturer spec sheet when checking local requirements — structures with published ratings are easier to permit than generic "heavy-duty" structures with no documentation.

Frequently Asked Questions

How many people does it take to assemble this carport?

It's designed for two people working together over roughly a day. The adaptive-screw tube frame system uses labeled parts and step-by-step instructions, and all hardware and tools are included, so you're not sourcing extra fasteners or guessing at an unlabeled parts diagram.

What surfaces can I anchor it to?

The 10 included heavy-duty anchor kits secure the structure to grass, asphalt, or concrete. With 10 anchor points instead of the 4–6 found on most carports, every leg and intermediate support can be properly secured to the ground.

Will it actually hold up in high wind or heavy snow?

It's engineered to a 100 MPH wind rating and a 35 PSF snow load — at this 12x20 ft footprint, that's roughly 8,400 lbs of accumulated snow before the structure reaches its design limit. Those are structural ratings, not marketing language, and they're also the documentation most HOA or zoning permit applications ask for.
