Shop for a carport in Canada and you'll see “metal carport” and “steel carport” used almost interchangeably, sometimes on the same product page. Are they the same thing, or is there a real difference that affects how your carport performs?
The short answer: every steel carport is a metal carport, but not every metal carport is made of steel. This guide explains what each term means, why the material matters in Canadian conditions, and what to check before you buy.
What “Metal Carport” Actually Means
“Metal carport” is the umbrella term. It describes any carport built with a metal frame and covers several different materials:
- Steel, the most common option for structural carports
- Aluminum, which is lighter and resists moisture well but is generally less rigid under heavy loads
- Mixed-metal builds that combine different frame and panel materials
When a Canadian shopper searches “metal carport,” they are usually looking at the broad category: a step up from fabric or tarp-style shelters, without yet specifying what the frame is made of.
What “Steel Carport” Specifically Means
A steel carport narrows the category to one material. That matters because steel is where most of the structural strength in this product category comes from. Compared with lighter-duty alternatives, steel frames typically offer:
- Higher load-bearing capacity
- Better resistance to bending or buckling under heavy loads
- Rigidity that holds up under sustained wind pressure
This is why most heavy duty carport options aimed at Canadian buyers use steel frames rather than aluminum.
Metal carport is the category. Steel carport is the material. Always confirm the frame material in the product specifications, not just the product name.
Why the Two Terms Get Mixed Up Online
“Metal carport” is the broader, higher-volume search term, while “steel carport” is more specific and is often used by buyers who already know they want structural strength. Retailers commonly use both terms on the same product so they show up for both kinds of searches.
In practice, a buyer in Canada searching for a metal carport is very often looking for what is technically a steel carport. They just haven't gotten specific yet. That is why the title of a listing should never be your only source of information.
Does the Difference Matter in Canada?
It depends on where you live and what you are protecting.
Canadian outdoor structures face snow, wind, freezing temperatures, moisture and repeated freeze-thaw cycles. In snow-heavy regions such as Alberta and the Prairies, and on exposed acreage properties, frame material and construction quality matter a great deal.
In a milder climate, such as parts of coastal British Columbia, a lighter aluminum-framed metal carport may be a reasonable and sometimes more affordable option. Even then, check the specifications rather than assuming.
What to Compare Beyond the Label
Frame specifications
Two carports that look identical in photos can be built very differently underneath. Check the tube dimensions, steel thickness or gauge, frame spacing and the hardware used at connection points. For example, Carports Factory Outlet steel carports use 2" x 2" 14-gauge steel framing with reinforced roof bracing on current models.
Corrosion protection
Galvanizing protects steel with a zinc coating that helps guard against corrosion, which is especially useful in a climate with road salt, snow and moisture. Powder coating adds an exterior finish on top. Our current range combines a hot-dip galvanized steel frame with a black powder-coated finish. Ask any supplier exactly how the steel is protected instead of relying on phrases like “weather resistant.”
Roof panels
The roof is your main barrier against rain and snow. Check the material, thickness, finish and how the panels attach to the frame. Our current steel carport range uses 27-gauge (0.40 mm) galvanized steel roof panels.
Structural bracing
Bracing helps the frame work as one connected structure. Confirm that the braces shown in photos are actually included, not sold as an upgrade. Our current carports include diagonal reinforced roof bracing as standard.
Anchoring
Even a strong frame needs the right anchoring for your installation surface, whether that is concrete, gravel, compacted ground or asphalt. Anchoring should match your site and local conditions.
Snow and Wind: Be Careful With General Claims
Snow and wind conditions vary widely across Canada. A property in southern British Columbia faces very different conditions from one in Alberta, Saskatchewan, Ontario or Quebec.
For that reason, treat any single snow or wind figure with caution unless it is backed by documentation for the specific product. If your municipality requires an engineered snow load or building approval, confirm those requirements before you buy or install. A general marketing statement should never replace site-specific requirements from your municipality or a qualified professional.
Metal or Steel Carport vs. Fabric Shelter
Canadian shoppers also compare metal and steel carports with lower-cost fabric shelters, but these are not the same type of structure. A fabric shelter typically uses a lightweight frame with a flexible cover. A steel-roof carport uses structural steel framing with rigid metal roof panels.
Fabric shelters may suit temporary or lighter-duty needs. A galvanized steel carport is a more permanent covered parking solution. A lower price does not necessarily mean you are comparing equivalent structures.
Questions to Ask Before You Buy
- What is the frame made of, and what are the tube size and thickness?
- Is the steel galvanized, and how is the finish applied?
- Is structural bracing included as standard?
- What material and thickness are the roof panels?
- What anchors are supplied, and are they suitable for my installation surface?
- What are the exact outside dimensions and vehicle clearance?
- What does the warranty cover, and for how long?
- Do I need a permit from my municipality?
Choosing the Right Size
Once you have settled on steel, measure what you need to protect. Do not size a carport by vehicle width alone. Allow for door-opening space, walking clearance and any storage needs.
An 11' wide carport suits many single-vehicle needs, including cars, SUVs, pickups, motorcycles and ATVs. Carports Factory Outlet offers 11' wide models in lengths from 15 ft to 40 ft. A 20' wide carport provides much more covered space for multiple vehicles, RVs, boats, trailers or acreage equipment, and is available in lengths from 20 ft to 40 ft.
Always check complete dimensions and clearances before ordering, especially for RVs and trailers.
At Carports Factory Outlet in Rocky View County, Alberta, every carport we sell is built from hot-dip galvanized steel with a black powder-coated finish, galvanized steel roofing and diagonal reinforced roof bracing, engineered for Canadian conditions.

Frequently Asked Questions
Is a steel carport the same as a metal carport?
Not exactly. “Metal carport” is a broad category that can include steel or aluminum frames, while “steel carport” specifies the material. All steel carports are metal carports, but not all metal carports are steel.
Which is stronger, a steel or aluminum carport?
Steel generally offers higher load-bearing capacity and better resistance to bending, which is why most heavy duty carports made for Canadian conditions use steel frames.
How can I tell if a metal carport listing is actually steel?
Check the product specifications for the stated frame material, tube size and gauge. Do not rely on the product title alone, and ask the supplier if the details are unclear.
Does a galvanized steel carport rust?
Galvanized steel has a protective zinc coating that helps resist corrosion. Paired with a powder-coated finish, it holds up better outdoors than untreated steel, though no outdoor material is completely maintenance-free.
Are steel carports suitable for Canadian winters?
Steel carports can be used in Canadian conditions, but suitability depends on the structure, installation, anchoring, local snow and wind conditions and applicable building requirements. Check local requirements before installation.
Do I need a permit for a carport in Canada?
Permit requirements vary by province and municipality and can depend on the size and location of the structure. Contact your local municipality before installation.
Are steel carports more expensive than fabric shelters?
Steel carports typically cost more upfront than fabric shelters, but they are a more permanent structure with rigid roofing and a heavier frame, so the two are not directly comparable.
Find the Right Carport for Your Property
Start with your vehicle, available space, installation surface and local conditions. Look past the label and compare the actual frame, galvanized protection, roofing, bracing, anchoring, dimensions and warranty.
