Composition of railings
The composition of the railings should be beautiful, and the overall appearance should be beautiful and repeated continuously over a long distance, thus producing a rhythmic beauty. Therefore, some specific patterns and logos are often inferior to the abstract geometric lines. At the same time, the composition of the railings must obey the requirements of the environment. For example, the railings of the arch bridges are arched along the bridge. The railings of the flat bridges are sometimes only two horizontal lines, which echo the shape of the flat bridge of the water. In addition, in addition to the aesthetics of the railing, it is also necessary to consider the cost, to be dense and dense, the materials used are appropriate, and cannot exceed the budget.
