The anti-glare plate is a traffic safety product that is manufactured and installed on the central partition of the expressway to solve the glare of the opposite car lights. It is mostly installed on the guardrail of the central separation belt of the expressway or between the guardrails, and some are set on the movable guardrail of the central opening. The materials are divided into steel anti-glare plates, plastic anti-glare plates, and FRP anti-glare plates. In terms of appearance, common straight bars, anti-S-shaped, anti-relief anti-glare boards, highway landscape anti-glare boards, etc. are common.
