Introducing Eco Pickled Surface (EPS)
The future of pickling technology has arrived at Stripco. 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 it's proven to perform as well or better than acid pickled material. Use this chart to compare the technologies.
