Originally beginning as a producer of high quality products for armed forces worldwide under the name of Dunlop GRG, the company became part of the Trelleborg Group in 2005. Meeting the exacting material standards of armed forces proved an ideal basis for developing heavy-duty products for highly demanding commercial applications. Our high quality service is backed up by our expertise in the area of flexible containment engineering and the ability to consistently produce to the highest standard demanded by present day markets.
