Types of Roof Bars: Steel vs. Aluminium, Adjustable vs. Fixed

Steel Roof Bars

Steel roof bars are a popular choice for many van owners due to their strength and durability. These bars are designed to withstand heavy loads, making them ideal for carrying large or bulky items, such as bikes, roof boxes, or camping gear.

Pros of Steel Roof Bars:

• Strength: Steel is incredibly strong and can carry heavy loads without bending or flexing.

• Longevity: Steel roof bars are durable and can last for years with the right care and maintenance.

• Affordability: Steel is generally less expensive than aluminum, making it a budget-friendly option.

Cons of Steel Roof Bars:

• Weight: Steel bars are heavier than aluminum, which can impact your van’s fuel efficiency and overall weight limit.

• Rust: Steel can rust if not properly maintained, so it requires extra care to keep it clean and protected.

• Corrosion Risk: Exposure to the elements over time can lead to corrosion, especially in coastal or wet areas.

Ideal For:

Steel roof bars are best suited for van lifers who need to carry heavy equipment and are okay with a bit of extra weight. If you plan to transport large items like kayaks, heavy luggage, or even solar panels, steel bars are a solid choice.

Aluminum Roof Bars

Aluminum roof bars, on the other hand, are a more lightweight and rust-resistant alternative to steel. Made from high-quality aluminum alloys, these roof bars provide a combination of strength and lightness, making them perfect for van lifers who prioritize fuel efficiency and ease of handling.

Pros of Aluminum Roof Bars:

• Lightweight: Aluminum roof bars are significantly lighter than steel, which helps improve fuel efficiency and makes them easier to handle during installation.

• Rust-Resistant: Unlike steel, aluminum doesn't rust, which makes it ideal for those who will be traveling in wet or coastal areas.

• Aerodynamic: Many aluminum roof bars are designed with aerodynamics in mind, which reduces wind noise and drag.

Cons of Aluminum Roof Bars:

• Lower Load Capacity: Aluminum bars tend to have a lower weight limit than steel, so they may not be suitable for carrying extremely heavy loads.

• More Expensive: Aluminum roof bars are generally more expensive than steel, which could be a consideration for those on a budget.

• Dents and Scratches: While strong, aluminum can be more prone to dents and scratches if not carefully maintained.

Ideal For:

If you’re looking for a lightweight, rust-resistant, and fuel-efficient option for lighter loads (such as luggage, bikes, or small roof boxes), aluminum roof bars are an excellent choice.

Adjustable Roof Bars

Adjustable roof bars are a versatile solution for van lifers who need flexibility in their setup. These bars can be extended or retracted, allowing you to adjust the width of the roof rack to fit different types of gear and storage solutions.

Pros of Adjustable Roof Bars:

• Flexibility: You can adjust the width to fit different items, making them a great option for those who need a variety of storage options.

• Convenience: The ability to adjust the roof bars means you don’t have to worry about purchasing multiple racks for different loads.

• Easy to Install and Remove: Adjustable roof bars often have a quick-release mechanism, making them easy to install and remove when not needed.

Cons of Adjustable Roof Bars:

• Less Aerodynamic: Depending on the design, adjustable bars may be less aerodynamic than fixed ones, potentially causing more wind resistance and noise.

• Slightly Heavier: Due to the mechanism that allows for adjustments, adjustable bars can be slightly heavier than fixed bars.

• Possible Less Durability: The moving parts in adjustable bars can sometimes wear out over time, potentially leading to maintenance issues.

Ideal For:

Adjustable roof bars are perfect for van owners who need to transport different types of gear, such as bikes, canoes, or luggage. They offer the flexibility to adapt your storage needs as they change.

Fixed Roof Bars

Fixed roof bars are typically a permanent installation on your van, providing a sturdy and stable mounting point for your roof rack system. These bars are usually less adjustable but are often more reliable for long-term use.

Pros of Fixed Roof Bars:

• Sturdy: Fixed roof bars provide a solid, reliable mounting point that’s ideal for carrying heavy gear.

• Durable: With fewer moving parts, fixed roof bars tend to last longer and require less maintenance.

• More Aerodynamic: Fixed roof bars are generally more aerodynamic than adjustable bars, reducing wind drag and noise.

Cons of Fixed Roof Bars:

• Less Flexibility: Fixed bars can’t be adjusted to carry different types of gear, which means you might need separate storage solutions for specific items.

• Installation: Fixed roof bars may require more installation time and effort, and may be harder to remove.

• Permanent Setup: Once installed, fixed roof bars are not easy to move, so they might not be ideal for those who need to constantly change their storage setup.

Ideal For:

If you have a specific storage solution in mind and don’t need to adjust the width of your roof bars, fixed roof bars are perfect. They are especially useful for carrying heavy loads and long-term van lifers who need stability and reliability.

Which Option Is Right for You?

Choosing between steel and aluminium, as well as adjustable and fixed roof bars, depends on your storage needs, budget, and long-term van life goals. If you prioritize carrying heavier loads and don’t mind a bit of extra weight, steel roof bars are a great choice. For those who need lightweight and rust-resistant solutions, aluminum is the way to go. Meanwhile, adjustable roof bars offer flexibility, while fixed roof bars provide a solid, reliable foundation for carrying gear.

By understanding the pros and cons of each option, you’ll be better equipped to choose the right roof bars for your van conversion and lifestyle.

Conclusion

Roof bars are an essential part of your van conversion if you need additional storage, and selecting the right ones will ensure your gear is transported safely and efficiently. Whether you opt for steel or aluminum, adjustable or fixed, the key is finding what works best for your van’s needs and your travel style.
