At Metalfer, our commitment to the principles of the circular economy is unwavering, and we are proud to present our innovative product – the Metalfer® Aggregate. This exceptional product, created as a by-product of the electric arc furnace steelmaking process, redefines the value of what was previously considered waste, turning it into a resource of extraordinary utility.

The steelmaking process generates a by-product known as “slag”. When reprocessed, the slag becomes a high-quality aggregate with physical and mechanical characteristics that surpass traditional aggregate. Our Metalfer® Aggregate is a unique fusion of micro- and macro-roughness that improves road grip. This results in the creation of a pavement with exceptional adhesion, sound absorption and water drainage capabilities.

Apart from its superior features, Metalfer® Aggregate symbolizes Metalfer’s commitment to environmental sustainability. On the one hand, it shows the successful valorization of an industrial by-product, which would otherwise be classified as waste, and on the other hand, it serves as a sustainable alternative to natural raw materials, reducing the pressure on overexploitation of natural resources.

The introduction of Metalfer® Aggregates is in line with our mission to encourage the sustainable use of resources and demonstrate how industrial processes can be aligned with environmental sustainability. We are proud to offer a product that not only meets the requirements of modern construction, but also respects and protects our environment. Metalfer® Aggregate is a confirmation of our commitment to quality, performance and sustainability – a true reflection of our values.
