For EPCs and roll manufacturers serving the pulp and paper industry, Outokumpu Prefab is an indispensable provider of suction roll shell blanks. Prefab specializes in duplex stainless steel grades specifically designed for suction roll shells.
Low stress levels and the absence of detrimental imperfections in the shell are essential to ensure long lifespan.

Shells that deliver a solid return on investment, performing at optimum speed and quality in a long-life cycle.
Through Prefab’s proprietary roll-forming and heat treatment processes and access to plate in any thickness from Outokumpu’s own Degerfors mill, manufacturers enjoy nearly limitless flexibility – including hard-to-find large shells.
