Steinag

What Steinag does

Steinag B.V. is a Netherlands-based B2B supplier of primary and secondary mineral raw materials serving the Benelux market. Established in 2021 as a joint venture with AG für Steinindustrie (a German family-owned producer operating since 1921), Freriks Holding BV and Heijting Holding BV, the company operates from Heteren and targets civil engineering (GWW), concrete industry, railway, horticulture and recreation segments with a sales-led model and a small in-house team supplemented by channel partners. The product portfolio spans lightweight volcanic aggregates (Lava from Germany and Turkey, Bims/pumice, Flugsand, SteinLight, Waschbims), secondary and circular products (Schuimglas foam glass from 100% recycled glass, Vulmagran), conventional aggregates (Basalt, Moräne crushed stone, Grensmaas gravel, Belgian and Spanish limestone, Greywackey, sea gravel) and color minerals for concrete and asphalt.

Pricing is quote-based, delivered on flexible commercial terms (ex-works, free to quay, free on site) with multi-modal logistics spanning inland barge, sea freight and truck. The go-to-market relies on three named sales/logistics staff managing direct enterprise relationships and on channel partnerships such as the June 2024 alliance with Stoter Bouwgrondstoffen for NE Netherlands distribution. Products are certified to Dutch and European standards including EN-13450 and ProRail's SPC00353-1 specification for quartz-free rail ballast, and the company's Turkish basalt quarry partnership delivers a minimum of 150,000 tons annually into that framework. Sourcing spans Germany, Turkey, Spain, Scandinavia, the UK and the Netherlands, drawing on a parent-backed multi-decade reserve profile.

The business captures structurally driven demand: roughly 30% of Dutch territory is affected by soil settlement (creating sustained need for lightweight aggregates), and the Ministry of Infrastructure and Water Management's 1 January 2025 regulation broadening glass foam applicability materially expanded the addressable market for secondary aggregates. Revenue mechanics are one-time bulk-material sales rather than recurring contracts, with pricing tied to type, volume and delivery terms and exposed to low-water surcharges on Rhine barge transport during drought conditions. No software, AI, or digital platform offering is part of the business.

Broad incumbents

• Holcim: Global leader in building materials and aggregates with significant European and Benelux operations. Competes broadly with Steinag in aggregates and concrete materials, but at a vastly larger scale across the full construction value chain.
• CRH plc: Global building materials group with extensive European aggregates and concrete operations. Overlaps with Steinag in construction aggregates and lightweight materials, though operating across the full building materials spectrum rather than specialty aggregates.
• Heidelberg Materials: Global building materials giant producing aggregates, cement, ready-mixed concrete, and specialty products across Europe including Benelux. Overlaps with Steinag in aggregates and concrete materials, but as a much larger diversified incumbent rather than niche specialist.

Regional players

• Laterlite: Italian producer of expanded clay lightweight aggregate (Laterlite, Leca) for construction, infrastructure, and horticulture. Comparable product portfolio to Steinag's lightweight aggregate range, but operates primarily in Southern Europe/Middle East rather than Benelux.
