About our tubes for construction

Our Tubembal plant, located in Portugal operates internationally and is one of the leading companies in manufacturing cardboard tubes, cores and edge protectors. We provide a specific range of cardboard tubes for the construction field. The Cofratek® tube is the ideal way to build circular columns. Its easy handling allows the use of non-specialised labour, since it is prefabricated and only needs to be placed in the desired location to obtain a perfect finish. The shuttering tube is entirely comprised of recycled and recyclable cardboard, which makes it an environmentally friendly product.
