If you own a big utility vehicle, such as an SUV, you will notice that it features structures just below the door bases. These structures serve as extra steps, much similar to the function of the rungs of a ladder. These extra steps can either be Nerf bars or running boards. Nerf bars are tubular structures with rubber coating on the surface. On the other hand, running boards are flat metal boards that are reinforced by metal frames. In either case, a Nerf bar or a running board runs from the rear fender end of the front wheel to the front fender end of the rear wheel.
Nerf bars are simpler and more stable. They are also comparably easier to install because they do not feature too many supporting frames. The braces of Nerf bars can simply be bolted under the chassis of the automobile. However, stepping on them may require some balancing. By comparison, running boards are lighter and they provide broader stepping surface. If Nerf bars are made from chrome-plated stainless steel, running boards are commonly constructed from aluminum materials. Their structural rigidity is secured by the multiple frames that support them. Meanwhile, the structural integrity of Nerf bars is assured by their tubular shape.
Nerf bars and running boards provide extra convenience for passengers who are boarding or dismounting your utility vehicle. The height of a typical vehicle may post some problems to passengers. Since these extra steps provide wider stepping areas, the passengers’ feet will not immediately fall on the ground or on the floor of the vehicle. If their shoes are muddy or dirty, the Nerf bars or running boards can serve as foot wipers. You may also use these structures as the stepping structures when fixing roof cargoes of your SUV. You can have more secure footing when stepping on them.
