Today's bridge guardrails are widely used, applied in all aspects of life, bringing convenience to our society. In the process of design changes, it should also be avoided to be trivial and chaotic.

Defects in the appearance design of bridge guardrails:

Firstly, regardless of the bridge type, the form of ancient bridge railings appears unordered.

Secondly, excessive decoration or embellishment, with patterns lacking regularity, can result in a clumsy outcome. For instance, the top of a bridge railing in Huoxian County, Shanxi Province features figures, animals, utensils, etc., which lack a common theme and are comical.

Thirdly, the components that make up the bridge railing are overly fine and densely distributed.

Bridge railing design should complement the bridge style. The design of the bridge railing is an integral part of the overall structure, intended to enhance and augment the beauty of the entire bridge. Therefore, the railing design should be adaptable to the bridge style and maintain a consistent theme.
