Let's talk about the step distance first: the step distance is the distance between the axis of the upper and lower ledger. But it should be noted that the story height mentioned here has nothing to do with the building height, it just refers to the story height of the scaffolding.

Standard span: You may not understand the standard span. The standard span also has a name called the standard longitudinal distance, which is the longitudinal distance between the standard and the standard. This distance is generally 1500mm.

Standard horizontal distance: Same as standard span (standard vertical distance), Standard horizontal distance is also the distance between standard in the transverse direction. So someone asked at this time, what about single-row scaffolding? Single-row scaffolding also includes the distance between the standard and the building. This distance is generally 800mm for ordinary scaffolding. There are 900mm, 1200mm and 1500mm options for the buckle scaffolding. Greatly save materials.
