Metal Carport Garage

A Canglong metal carport garage is a prefabricated steel shelter engineered to protect cars, light trucks, equipment and inventory without the cost, foundation work or permitting complexity of a fully enclosed garage. The frame uses hot-dip galvanized Q235 or Q355 steel, while the roof can be finished with corrugated metal sheeting, insulated sandwich panels or polycarbonate skylight panels depending on the climate and budget.

Unlike our enclosed one-car, two-car or three-car steel garages, the metal carport is intentionally open-sided or partially enclosed. That design keeps construction time short, improves natural ventilation and gives drivers clear entry and exit lines. It is the practical choice when the priority is weather protection and fast installation rather than lockable storage.

Structural Composition

Main Frame	Welded or bolted portal frame in hot-dip galvanized Q235 / Q355 steel
Beams & Columns	H-shaped or box-section steel, sized by span and local load requirements
Purlins	Galvanized C-section or Z-section purlins, pre-punched for fast assembly
Roof System	Corrugated color steel sheet, insulated EPS/PU/rock wool sandwich panel, or polycarbonate panel
Bracing	Rod bracing, angle bracing or cross-bracing to stabilize longitudinal loads
Foundation	Concrete footings with anchor bolts, or ground anchors for temporary installations
Surface Finish	Hot-dip galvanizing ≥80 µm plus optional PVDF or polyester coating

Technical Parameters

The dimensions below are typical ranges. Canglong supplies custom steel carport kits drawn to site width, clearance height, roof style and local wind or snow loads.

Parameter	Standard Range	Notes
Span	3 m – 12 m per bay	Wider spans use built-up H-beams or truss frames
Length	Custom, in 3 m or 6 m modules	Add bays to cover more vehicles
Eave Height	2.4 m – 4.5 m	Higher for RVs, vans or small trucks
Roof Slope	1:10 to 1:4	Steeper slopes improve drainage in snow regions
Steel Grade	Q235B / Q355B (equivalent to ASTM A36 / Grade 50)	Q355 recommended for high wind or seismic zones
Wind Load	Engineered to 120 km/h – 180 km/h+	Verified by structural calculation report
Snow Load	0.5 kN/m² – 2.0 kN/m²	Increase with roof pitch and purlin spacing
Service Life	25 – 50 years	Depends on coating system and environment

Core Advantages

• Engineered for local loads, not guesswork. Every metal carport garage is accompanied by a structural calculation note that lists wind speed, snow load, seismic coefficient and foundation reaction. Buyers receive drawings stamped for permit submission where required.
• Galvanized steel frame with measurable corrosion protection. Main columns and beams are hot-dip galvanized to ≥80 µm. Optional PVDF or high-build polyester coatings extend surface life in coastal or high-UV environments beyond 25 years.
• Prefabricated kit, short site timeline. Components are cut, drilled and pre-assembled in our factory, then packed by sequence. A two-bay residential steel carport can typically be installed in one to two days with a small crew and basic lifting equipment.
• Flexible configuration without duplicating garage pages. Choose open sides, partial side panels, gable ends, skylight panels or integrated gutters. The result is a weather shelter, not a competing enclosed garage product.
• Export-ready packaging and documentation. We supply loading plans, packing lists, bill of materials, installation drawings and bolt schedules. Container loading is optimized to reduce freight cost and on-site sorting time.

Typical Applications

The metal carport garage is used where fast, open coverage is more important than a lockable room. Typical installations include:

• Residential driveways: Cover for daily-use cars, SUVs, motorbikes and bicycles where a full garage is not required.
• Commercial visitor parking: Retail lots, office campuses and hospitality properties that need uniform covered bays.
• Fleet and equipment shelter: Light commercial vehicles, work trucks, generators and landscaping equipment that need rain and sun protection.
• RV, boat and van covers: Higher-clearance steel carport frames designed to accommodate oversized vehicles.

For fully enclosed storage, see our two-car garage for a lockable vehicle storage option. For farm machinery and larger working vehicles, refer to our agricultural vehicle garage.
