Steel slag aggregates in the 20 to 40 mm size range are well-suited for heavy-duty applications such as sub-base construction, drainage layers, embankments, and railway ballast. Their coarse, angular structure provides excellent interlocking, resulting in superior load-bearing capacity, enhanced stability, and resistance to deformation and weathering over time.

These robust particles ensure long-lasting performance even under extreme conditions, making them a reliable choice for high-impact infrastructure. As a by-product of the steel industry, this material also supports sustainability by reducing the use of natural aggregates—offering both environmental and economic advantages for modern construction projects.
