Solid Iron Wall is a 4000 year old technique created by the ancestors of the Beylin Temple. It is a defensive technique that is for told to be impenetrable. The technique is noted to be like mountains that won't budge against any storm. Chi-yun first uses this technique to block all of Tsubasa's normal attacks without fail. Dashan next uses it to create a barrier that leaves Pegasus at bay for most of his match until Pegasus is able to break through it. Dashan also used its power to successfuly defend against Julian's Gravity Brave Special Move in it's left rotaion attack mode. However, it broke against Klaus's Claw of the Storm special move.
