Introducing Eco Pickled Surface (EPS)
The future of pickling technology is coming to Stripco in December 2011. Eco Pickled Surface (EPS) is an environmentally friendly pickling technology that uses slurry blasting as an alternative to traditional acid pickling.
There are no toxic chemicals involved in the process. Rather, a mixture of steel grit, water, and rust-inhibitor is used to remove scale from hot rolled black surfaces. The innovative approach to pickling also creates a more consistent surface, removes light hot mill defects, and is available dry but still corrosion-resistant. See the difference for yourself.
EPS has been thoroughly tested in manufacturing environments, and its proven to perform as well or better than acid pickled material. Use this chart to compare the technologies.

A. Nine automotive OEM paint tests confirm EPS meets or exceeds industry specifications.
B. EPS has a lower Rz (standard deviation) and is typically 3-4 Ra higher than traditional acid-pickled surface.
C. Rolled in Scale; Roll Marks; Pitts; Silicon Streaks; Scratches.
D. Stamping - no oil film barrier. Roll-forming - less tooling slip.
E. Common extras apply.
F. Oiled surface available.
