Product Details
[ Product Description ]
▪ PS Ball is a spinel structured and eco-friendly output of well treated unstable metal slags which occur during steel work.
[ Product Features ]
1. Field of using
1) Abrasive blasting material, Roofing Granules, Reinforcement material, Weight material
2) Asphalt concrete, Non-Slip material, Concrete secondary products
2. Advantage of PS Ball
1) Acquiring the stability in the collapsing from expansion compare to the current crushed slag aggregate
2) Making high added value for the usage of the slags used for simple purpose
