China, the ancient name of railing, is also called Goulan, which is a safety facility on bridges and buildings. Railings play the role of separation and guidance in use, so that the boundaries of the divided areas are clear and definite. The railings designed are very decorative. There were balustrade-like members on the ritual vessels in the Zhou Dynasty. In the Han dynasty, lying railings were the most common. During the Six Dynasties, hooks were popular. In Yungang Grottoes and Dunhuang murals, you can find people standing at the corner of railings or looking for sticks. The wooden railings in the Yuan, Ming and Qing Dynasties are slender, while the stone railings are gradually separated from the wooden railings and tend to be heavy. After the late Qing Dynasty, the proportions, scales and decorative forms of western classical railings were introduced into China. The materials and shapes of modern railings are more diverse.

The railing is made of wood, stone, concrete, brick, tile, bamboo, metal, plexiglass and plastic. The height of the railing mainly depends on the objects and places used, generally 900 mm high; Stair railings in kindergartens and primary schools can also be made into double handrails for adults and children respectively; In high-risk places, it can be improved as appropriate. When the stair width exceeds 1.4m, double handrails should be set (the side against the wall should be set with handrails against the wall); when it exceeds 2.4m, handrails should be added in the middle. In residential buildings, railings should not have too much space or climb stairs.
