Hy-rib panels are pieces of metal mesh that builders use to reinforce concrete structures. The mesh is created by welding wires together to form a grid pattern of repeating squares.
Imagine making a basket out of metal wire. Now imagine that the basket is flat instead of being rounded. That's what the hy-rib panel looks like. It's a flat sheet of metal with lots of small squares in it.
When builders pour concrete into a mold or form, they often want to make sure the final structure is strong enough to support the weight of people or things on top of it. That's where the hy-rib comes in.
The hy-rib is placed into the concrete mold before the concrete is poured in. As the concrete dries and hardens, it fills in around the squares of the hy-rib. This creates a kind of skeleton inside the concrete structure that helps it stay strong and stable.
Think of the hy-rib like the bones in your body. Your bones give your body support and structure. Without them, you would be a floppy mess. Similarly, without the hy-rib, a concrete structure might crumble or collapse under its own weight.
