Roof racks are an essential tool for increasing the load capacity of vehicles, whether for private or commercial use. Depending on the type of vehicle (car or commercial vehicle), roof racks can vary in design, strength, and load capacity.

1. Car Roof Racks

Car roof racks are generally designed to fit different roof types and needs. Here are the main types:

Types of bars:

Aluminum bars : Lightweight and corrosion-resistant, they are very popular for heavily used cars. Aluminum bars are ideal for moderate loads and also offer low air resistance.

Steel bars : Stronger, but heavier than aluminum ones. Suitable for vehicles carrying heavy loads or for commercial use.

Aero bars : Designed to minimize air resistance and improve fuel efficiency. These bars are quieter and are perfect for vehicles that travel long distances.

Assembly:

Cross bars : These mount transversely across the roof of the vehicle, and are the most common option.

Roof rail mounting : Some car models are equipped with longitudinal roof rails to which the crossbars are attached. This system is safer and more robust.

Universal system : For cars without longitudinal bars, there are roof rack systems that do not require permanent modifications to the vehicle, but are mounted directly on the roof with brackets and hooks.

Accessories:

Straps and securing systems : To ensure that loads are securely fastened during transport, straps or cargo netting can be used.

Bike racks, ski racks and kayak racks : There are specific supports to mount on the bars to transport sports equipment.

2. Roof bars for commercial vehicles

Roof racks for commercial vehicles , such as vans, trucks, and specialized vehicles, are generally sturdier and capable of handling heavier loads than car racks. These vehicles are often used to transport tools, materials, and equipment, so the racks must ensure maximum stability and safety.

Types of bars for commercial vehicles:

Reinforced steel bars : Stronger and more durable, ideal for heavy loads such as building materials or tools. These bars are also better suited to harsh weather conditions and intensive use.

Aluminum bars : Although less durable than steel, aluminum bars are quite common for vans and light commercial vehicles. They are lighter and therefore reduce the vehicle's weight.

Galvanized or painted steel bars : To prevent rust and ensure long life, many bars are treated with galvanization or painting.

Assembly:

Roof racks attached to brackets : On commercial vehicles, roof racks can be mounted using special brackets attached to attachment points on the vehicle's roof. These brackets can be fixed or adjustable.

Roof bars for vans with flat or panel roofs : Some vans do not have a completely smooth surface, so special mounting solutions are required, such as bars that fix to special brackets or screws, to ensure a secure anchoring.

Accessories for commercial vehicles:

Pipe and pole carriers : Used for transporting long materials such as pipes, poles or beams.

Baskets or Shelves : For organizing and transporting smaller loads and equipment.

Professional lashing systems : Such as sturdy straps and hooks to secure your load safely.

Considerations for Choosing Bars

Load capacity : Make sure the bars can support the weight of the loads you intend to transport. Car bars typically have a lower load capacity than those for commercial vehicles.

Vehicle type : Check whether your car or commercial vehicle has longitudinal bars (to easily fit cross bars) or whether you need to opt for universal solutions.

Load Securing : Ensure the securing system is secure and the load does not shift during transport. Commercial vehicles often require more robust solutions to prevent the load from damaging the vehicle or other road users.
