The corrugated height and the number of corrugations per 300 mm length determine the type of corrugated board. The  type is actually the relevant regulations on the size of the corrugated.

Commonly used  types are: A watt (type), B watt (type), C watt (type), E watt (type)

With the development of corrugating roller production technology and packaging industry, some smaller types such as F, G, N, O, etc.

The common types of transport packaging are type A and type B.

Type A corrugated with the highest height and spacing, soft, elastic and good cushioning performance.

The B type has a higher flat compressive strength and is suitable for packaging harder products. At the same time, because the corrugation spacing is small, the paper is relatively flat and the printing effect is good.
The C watt is between A watt and B watt and is currently used less separately. However, where appropriate, BC corrugations can be used instead of AB corrugated.

Below E watts, called micro-corrugated, is intended to replace thick cardboard.
