EPS is the Green Steel Technology |
EPS pickles steel without the use of hazardous acids. It uses only steel grit and ordinary water and recirculates both for continuous re-use. EPS processing burns no fossil fuel for process heat, so it has lower, stable energy costs.
EPS users get a 'green' benefit as well. EPS resists rusting with no need for protective oil or coating. That means there's no need for solvents to strip off the oil film, plus a potentially leaner paint pre-treatment than HRPO.
Slurry Blasting is Not Shot Blasting
Continuous dry shot blasting of steel strip isn't practical. The air handling/dust collection systems take up immense space. The dust/air mixture itself is highly combustible. All areas around such a system stay coated in a layer of dust – it's unavoidable.
As a wet process, Slurry Blasting produces no dust. Collection and re-use of the abrasive grit is simple and safe. The steel strip is rinsed clean, with no dislodged scale, grit or other contaminants embedding into the surface, as can happen with shot blasting.
Superior Surface
EPS produces a surface superior to acid pickling or shot blasting:
- Clean, uniform appearance
- No 'over-pickling' or staining
- Mitigates minor surface flaws like pitting, roll marks, etc.
- Custom surface roughness
- RUST RESISTANT so no aggravating oil needed
EPS' custom surface roughness has the capability to provide a smoother surface for stampers and cold reducers, or a rougher surface for optimum paint and galvanized coating adhesion.
