C#BLOK® is a wide range of structural composite parts offer by  H-PreC

This company was founded in 2015 by Daniel Legal co-founder of Gemalto (world leader in digital security) and Dominique Crassous owner of many patents.

During the last three years, we developed two original processes to make structural carbon parts on an industrial line and a new design for composite rims. These exclusive industrial patented processes allow us to replace machined or casted aluminum parts by a composite part, but also to position ourselves in the palette of high range metallic parts in terms of resistance, reliability and price.

Today we are ready to supply our customers with high tech products at a real market price.
