In the fields of counter-terrorism, riot control, emergency response and other security areas, PC Anti Riot Shields are key equipment to ensure the safety of personnel's lives. They not only need to have protective performance against impacts, punctures, fragments, etc., but also need to meet the lightweight requirements for portability and mobility. There may seem to be a contradiction between the two, but in reality, a balance between performance and weight can be achieved through the synergistic effect of materials, structures, and processes. The realization of this balance is the core manifestation of modern protective equipment engineering technology.
