The height of each level of a construction scaffold is generally 1.80 m; the first row can reach 2.0 m, while the top level can be adjusted according to the height of the building (but must not exceed 1.80 m).
B. 1.2m Analysis: For the external scaffolding used in wall construction, the height of each tier is called the ‘step distance’. Section 6, ‘Structural Requirements’, of JBJ130-2001 \"Safety Technical Specifications for Fastened Steel Tubular Scaffolds in Building Construction\" specifies two step distances: 1.20–1.35 m and 1.80 m. 1.20-1.35 meters allows for flexible adjustment according to different ceiling heights ； 1.80 meters, specifically for exterior wall painting.
