River guardrails are safety protection facilities specifically designed for the banks of rivers, lakes, and other water bodies. With "fall prevention, water corrosion resistance, and landscape adaptation" as the core functions, they are made of weather resistant substrates such as galvanized steel and stainless steel, reinforced and welded, and treated with anti-corrosion. It can not only prevent people and objects from accidentally falling into water bodies, but also adapt to the high humidity and abundant water environment of rivers. At the same time, it can be integrated with waterfront landscapes through its shape, color matching, and is a key facility to ensure the safety of water bodies and enhance the ecological environment. It is widely used in urban river trails, wetland park shorelines, reservoir shorelines, and other scenes.
