Walan Specialty Construction Products is a U.S.-based construction materials company focused on manufacturing and supplying supplementary cementitious materials for concrete. Its core product is ground granulated blast‑furnace slag (slag cement), produced by grinding granulated slag from steelmaking into a fine powder used in blended cements and concrete.
Walan’s materials are used by ready-mix and precast concrete producers, as well as in infrastructure and commercial construction, to enhance durability, strength, and workability while lowering clinker content and embodied carbon. The company serves regional markets in the northeastern United States through slag grinding and distribution operations.
