Stage flooring must meet the following three functional requirements:

(1) The performance (sports) function is designed to meet the requirements of various performances, particularly those with high physical demands like dance and acrobatics. It aims to minimize the actors' energy expenditure and maximize their acting prowess. Therefore, the floor must possess adequate elasticity, with vibration deformation and motion deformation being key indicators of this sports performance. Of course, wooden floors inherently offer excellent natural elasticity.

(2) Security Features

To prevent injuries during actors' movements on stage, the flooring is required to have a certain level of vibration absorption. This ensures that the impact forces from jumping and landing are adequately absorbed, reducing muscle fatigue and protecting the joints and ligaments in the legs and feet. It also aims to minimize the common ankle injuries seen in stage performances. Additionally, the flooring surface must have an appropriate coefficient of friction; both too slippery and too abrasive surfaces can lead to falls, increasing the load on the legs and causing fatigue and potential injuries.

(3) Technical Features

The load-bearing capacity and stability of stage wooden flooring must meet the requirements of various performances. With a large number of scenery, props, and equipment being transported on stage, the load-bearing capacity of the wooden flooring is crucial. Rolling load is a specific indicator of this performance. The requirements for the stage flooring when actors perform (especially for high-motion actions) are quite similar to those during basketball games. We can refer to the relevant standards for sports wooden flooring. Currently, the International Sports Flooring Technical Committee (OZST) has quantified the technical criteria, adopting the provisions of the German DIN 18032 standard to make detailed technical requirements for sports wooden flooring. Our country's sports wooden flooring also adopts this standard. It is divided into five parts. It is worth noting that although similar, the specific indicators are certainly still distinct. As for how much is suitable for the stage, it remains to be experimentally and exploratively determined by relevant experts.
