Structural channel

Imagine you have a small toy car that needs wheels to move. The wheels need to be attached to something that holds them in place and allows them to rotate. This something is called a "structural channel".

A structural channel is basically a long, narrow piece of metal that looks like a "U" shape. It's used in construction to reinforce buildings, bridges, and other structures. It's also used in manufacturing to create things like conveyor belts and machine frames.

The structural channel acts like a support beam. It's designed to distribute weight across a larger surface area, so the load doesn't concentrate in one spot. This helps prevent bending, warping, or breaking under the weight of heavy objects.

In short, a structural channel is a piece of metal that helps support heavy things and prevent them from breaking. It's kind of like a big metal hug for your toy car's wheels.
