Amiblu Poland Sp. z o.o.

At Amiblu, we engineer and manufacture Glass-fibre Reinforced Plastic (GRP) pipe systems for the world’s water and energy infrastructure. We pioneered the two technologies that shaped GRP pipe production worldwide – centrifugal casting and continuous filament winding – and we’ve been refining them since the 1950s. Today we operate in 125 countries driven by one ambition: to build infrastructure that lasts for generations, and to inspire people around the world to value water as we should.

This is how we work
