Stair-a building used as a component for vertical traffic between floors. Used for transportation links between floors and when the height difference is large. Stairs are also set up in multi-storey and high-rise buildings with elevators and escalators as the main vertical means of transport. Despite the use of elevators as the main vertical means of transport, high-rise buildings still have to keep stairs for escape in the event of a fire. The staircase consists of a continuous cascade of ladders (also known as Ladder running), a platform (rest platform) and a retaining member. The horizontal projection distance between the lowest and highest steps of the staircase is the ladder length, and the total height of the ladder is ladder height.

G363 is a very good substitute material for G687 and G664, which quarries are closed, due to the color similarness.
