Generally, metal bridge railings are prone to rusting. If made of stainless steel, regular cleaning can be carried out and water can be used directly. Stainless steel is most afraid of chloride ions, especially in areas near the sea; If it is wrought iron, it needs to be painted. Paint has a service life and requires maintenance over time. The specific time also depends on the degree of oxidation of the paint on your railing.

Practicality and aesthetics are the two main functions of bridge guardrails. With the advancement of materials and technology, meeting the practical requirements of guardrails is no longer a problem; The railings that are coordinated with the bridge structure and the surrounding environment are like the finishing touch, making the bridge magnificent and colorful. The carved railings of Jinshui Bridge and Yudai Bridge are magnificent, elegant and tempting; The stone lions with various shapes on the railing of Lugou Bridge are full of wit and are well-known far and wide. Science is so advanced that it requires our bridge architects to inherit and promote traditional architectural art, and fully utilize the landscape function of railings. Firstly, it is required that the railing design is compatible with the bridge type. Railings are a part of the overall structure of a bridge, and they should serve as a backdrop and reinforcement for the overall aesthetics of the bridge. Therefore, the shape of the railings should be able to adapt to the bridge type and have a consistent style. Secondly, the design of railings and bridges should be coordinated and unified with the surrounding environment.
