The baluster is a vertical molded shaft, square, or lathe-turned form in the stairways, parapets, and other architectural features. The primary purpose of the balusters is to prevent the potential safety risk of falling down from the stair. The common materials that it adopts are wood, stone, and less frequently metal and ceramic. Today, stainless steel is popular with most customers with its high durability. The stainless steel railing baluster systems consist of a group of balusters supporting a handrail, coping, or ornamental detail.
