Harsco Slag Product Earns Top Honors
June 15, 2016

CAMP HILL, PA (June 15, 2016) . . . Harsco Corporation (NYSE: HSC) announced today that its proprietary road surfacing material known as STEELSTOP® has been named Slag Product of the Year at the 11th Annual Global Slag Conference held recently in London.

STEELSTOP® is a formulated High Friction Surfacing material (HFS), meaning that it carries proven road safety advantages for situations where there is a high risk of skidding, such as approaches to traffic lights, pedestrian crossing or intersections. The material is applied as a surface treatment to increase the skid resistance of existing road surfaces. STEELSTOP® has been assessed for use through the British Board of Agrément, in line with the testing requirements of the Highway Authorities Product Approval Scheme. HAPAS maintains nationally-recognized approval criteria for innovative products and systems used in highway works in the UK, consistent with similar standards in the United States.

Harsco’s SteelPhalt™ business, a unit of the Company’s Metals & Minerals division, has been producing slag-based asphalt products in the UK for more than 50 years, leading the drive for sustainable asphalt materials produced almost entirely from recycled content. Steel slag’s inherent properties make it ideally suited for use as a surface course for roadmaking:

  • Exceptional strength and durability, which extends the life of the road andlengthens road maintenance intervals
  • High skid resistance maintained throughout the life of the road, based on slag’s capacity to regenerate its surface roughness over time
  • Avoids the depletion of quarried natural resources, and avoids the landfill of by-products through effective and responsible recycling

Harsco’s Metals & Minerals division is the largest and most comprehensive provider of onsite material processing and environmental services to the worldwide metals industry, with operations at approximately 140 customer sites across more than 30 countries. The division is a technology partner to cleaner, more efficient metal production, providing customers with economically and environmentally viable solutions for the treatment and reuse of production waste streams.
