In order to ensure the normal life of residents around the expressway, road barriers are generally set up on both sides of the expressway. The endurance board is the most suitable material for the resistant fence. The endurance board has excellent impact resistance and sound insulation effect. Even if it is hit by a strong impact, it will not break and cause secondary damage. It can ensure to a certain extent that it will reduce the damage to personal safety in the event of a car accident, and it can also protect the surrounding residents. Affected by noise, maintain a normal daily life.
