Scaffolding is divided into seven classes for width, two classes for headroom and six load classes. This division and classification also partially apply to mobile scaffolds as mobile work platforms.

In the standard, the width class is indicated by the letter W and two numbers. The seven width classes range from a width of 0.60 to 2.40 metres, in increments of 30 centimetres.

In Germany, system scaffolding generally conforms to height class H1 (headroom of less than 1.9 m in the area of the frame). If the headroom is 1.9 m or more, height class H2 applies.

The load class defines the maximum possible uniformly distributed load in a scaffold span (surface load q1 in [kN/m²]) or the maximum possible concentrated loads on defined surfaces (single load F1 on a surface measuring 500 x 500 mm or single load F2 on a surface measuring 200 x 200 mm). The selected load class must be suitable for the type of work to be performed. Load classes relevant to mobile scaffolding:

• Load class 1: Use for inspection work only (max. uniformly distributed live load q1 = 0.75 kN/m²; concentrated load F1 = 1.5 kN or F2 = 1.0 kN)
• Load class 2: Use for work that does not require any storage of building materials or components (max. uniformly distributed live load q1 = 1.5 kN/m²; max. concentrated load F1 = 1.5 kN or F2 = 1.0 kN)
• Load class 3: Use for work that does not require any storage of light building materials or components (max. uniformly distributed live load q1 = 2.0 kN/m²; max. concentrated load F1 = 1.5 kN or F2 = 1.0 kN)
