Moreover, I've always wondered how painful the weapons used in WWE actually are. Thankfully, I now know the answers, and you can read them below.
The WWE ring is made of foam cover that is significantly tight. The ring mat's top layer is a thin foam pad while an inch of plywood is placed below.
Because of the springs located below the inch-thick plywood, wrestlers do not get injured so easily once they land on the ring's mat. The whole ring is then kept together through the use of steel beams.
The steel beams used to support the ring's overall structure also serve as the ringside posts. They are very thick so they need to having paddings to avoid injuries at times.
Through the four ring posts, the turnbuckles are held along with some screws to hold the ring ropes. Thanks to the covers, the screws are covered and they are only as tough as a pillow if you decide to hit them.
These ropes are specifically made up of strengthening wires that have so much tension. This tension allows wrestlers to utilize the ropes' elasticity for some moves. Surprisingly, it is not that easy to use these ropes at first.
Outside the ring, hard foam mats that are like those used in karate studios are placed. They help protect wrestlers from hitting the concrete below the mats.
Hollow steel is used to form the barricades, along with the foam cushions inside. There is also a Velcro top to maintain the inner and outer foam.
The chairs used to hit wrestlers are actually made of light metal most of the time. This makes the chair cause less damage while producing loud sounds. However, some real steel ones are used as long as safety measures are followed.
The ladders are quite hollow, so they shake easily if someone tries to arrange it. However, it can still be painful if used with enough momentum.
The tables used in WWE are only made of thin wood so they could easily break. However, the steel steps are actually steel. The kendo stick wrestlers use sometimes is hollow and is easy to break. However, sledgehammers and steel pipes are authentic and are simply used with caution.
