What Are the Sides of a Truck Bed Called?

Truck beds come in all shapes and sizes, but they all have one thing in common: their sides are called bed rails. Bed rails, which are also known as truck bed rails, are an integral part of any truck bed and provide stability and structure to the overall design. While different manufacturers may use different materials for the construction of their truck beds, the basic concept remains the same: the sides of a truck bed are called bed rails.

Bed rails can be made from a variety of materials, including steel, aluminum and even plastic. Steel is the most common material used for truck bed rails due to its strength and durability.

Aluminum is also becoming increasingly popular due to its light weight and corrosion resistance. Plastic bed rails are less durable than steel or aluminum, but they offer a great option for those looking for a lightweight solution.

Bed rails serve two primary functions. The first is to support the cargo that is placed in the truck bed.

This means that they must be strong enough to support heavy loads without bending or breaking under pressure. The second function is to protect the cargo from damage caused by bouncing or shifting during transit. Bed rails help keep the cargo in place and reduce wear and tear on the surface of whatever is being transported.

No matter what type of material you choose for your truck bed rails, it’s important to make sure that they are properly installed so that they can perform their intended functions correctly. This means ensuring that all bolts are tightened correctly and all gaps between each rail are filled with sealant or other suitable material to prevent rusting or corrosion.


In conclusion, it can be said that regardless of your choice in material, bed rails are an important part of any truck bed design as they provide stability and structure while protecting the cargo from damage during transit. Make sure to properly install them so that they can do their job correctly!
