Amiblu is the world’s largest supplier of
GRP pipe systems and solutions.

Hobas and Flowtite glassfiber reinforced plastic pipe systems by Amiblu are the product of over five decades of innovation, experience and development. We are the largest producer and technology partner for GRP pipes in the world. Because of our composite engineering and material science skills, we offer a product with an expected service life of more than 150 years.


Amiblu’s two specialist technologies – Hobas centrifugally cast and Flowtite filament wound solutions – complement each other perfectly. Both product lines replace traditional corrosion sensitive materials like concrete, iron and steel. And being made of reinforced plastics, they match traditional materials for strength and hugely outperform them on weight, ease of handling, longevity and all-round sustainability.
