Understanding the Basics: Enclosed vs Open Metal Carport
Enclosed sidewall metal carports provide enhanced seasonal protection from the elements. The solid side panels shield your vehicles and equipment from driving rain, crosswinds, and direct sun while maintaining convenient, continuous drive-through access. Conversely, open carports feature completely open sides, maximizing perimeter clearance and making it easier to walk or work around your assets.
| Feature | Enclosed Carport | Open Carport |
|---|---|---|
| Protection Level | Three-sided (overhead canopy + side shielding) |
Overhead only (canopy shelter) |
| Wind & Driving Rain | Blocks crosswinds and lateral rain | Open to side winds and blowing rain |
| Ventilation | Good (airflow) | Excellent (airflow) |
| Side UV & Sun Exposure | Blocks intense afternoon sun and lateral UV rays | Open to low-angle sunlight from the sides |
| Snow Management | Prevents overhead build-up and blocks side drifts | Prevents overhead build-up only |
Key Considerations When Choosing
Side Screening vs. Open Perimeter
Choose the enclosed sidewall model if you need to shield vehicles from lateral UV rays and crosswinds. Choose the open sidewall model if you need maximum clearance to easily walk or work around the perimeter of your assets.
Site Exposure
Both models handle direct overhead rain and snow equally. However, if your site faces strong prevailing crosswinds or harsh, low-angle afternoon sun, the enclosed sidewalls provide a necessary physical barrier.
Budget
Because the enclosed sidewall model includes additional steel side panels, it carries a higher upfront material cost. Weigh the benefit of built-in side protection against your target budget.
Buying Tips for Choosing the Right Carport

When selecting between enclosed and open metal carports, consider the following practical checklist:
- Assess Site Wind and Sun: Determine if your parking spot is naturally shielded or highly exposed to lateral weather.
- Evaluate Space Requirements: Measure the available area and check local municipal regulations regarding structure size, property line setbacks, and required building permits.
- Budget Wisely: Factor in not just the purchase price but also the long-term maintenance and potential insurance costs.
- Installation Preparation: Ensure your concrete pad or foundation anchors match the footing requirements for a permanent or semi-permanent engineered steel structure.
Frequently Asked Questions (FAQ)
How are these metal carports installed?
Installation involves anchoring the heavy-duty steel frame directly into a solid base, such as a poured concrete slab, utilizing the manufacturer's specified anchoring hardware and guy wires for structural stability.
Can I use an open sidewall carport for winter protection?
Yes. Both configurations feature the exact same roof design, which completely prevents overhead snow and ice buildup on your vehicle. The open model simply remains exposed to blowing side-drifts.
Are there any zoning or permit restrictions for these carports?
Yes. Even though they feature an open-ended drive-through design, structures of this size are classified as accessory buildings. You must check your local municipal bylaws regarding building permits, property line setbacks, and regional snow load ratings before installation.
How do I maintain my metal carport?
Because these are durable, open-air steel structures, maintenance is minimal. Periodically wash down the panels to clear away dirt and inspect the ground anchors to ensure the framework remains securely locked down.
Which Metal Carport Style Fits Your Needs?
Choosing between an enclosed sidewall and an open sidewall metal carport ultimately depends on your specific site exposure and budget. If you require extra side screening against crosswinds and low-angle sun, the enclosed sidewall layout is an excellent choice. Conversely, for maximum perimeter clearance and straightforward drive-through protection, the standard open carport is the perfect fit for your outdoor storage setup.
