Grey board

Grey board is manufactured in 4 grades: 69, 72, 80 and 95 (with increasing surface smoothness). The most commonly used grade is grey board 72. The number of the grade indicates the specific gravity, for example GK 69 = 0.69 g/cm³.

Grey board is an interesting product. Beginning with its raw material – 100% recycled paper. Carelessly thrown away it would be a nuisance, but purposefully collected and carefully processed at Merckens it becomes a material with limitless possibilities – recognised with the environmental label “Blue Angel” and the FSC.

Grey board is invisible in many everyday objects, but gives inner strength and lasting stability. You can get an idea of this from our example applications.
