SQS - Special Quality Section Mills
Cutting-edge process and technology for Superior Quality Section manufacturing.
Sections are produced on 3-high or 2-high rolling stands, universal reversing, continuous or semi-continuous stands, and over the years this technology has moved on to different solutions, such as Danieli’s Profile Sizing Process, or PSP.
The PSP system is the cost-breaking innovation in the production of H-beams (up to 1,100-mm height & 400-mm flange), equal/unequal profiles, special sections and all types and sizes of rails.
By combining reversing intermediate/pre-finishing rolling in a UFR-Ultra Flexible Reversing mill with finishing-sizing rolling in a separate independent UF stand, PSP enhances product quality, plant productivity and efficiency at lower production costs. The independent single finishing/sizing pass provides the best tolerances thanks to small reductions, long life for rolls and guides, maximum roll pass design flexibility and best finished product surface.
