Second Life Steel Fiber

High-performance steel fibers from End-of-life tires (ELTs) is the near zero CO2 emissions solution for the concrete reinforcement. SDS provide steel fiber from ELTs with high tensile strength, close to zero rubber contamination, high aspect ratio and consistent performance. With our Star New Material (SNM) in house WaterJet ELTs recycling technology, we can create a close loop second life steel fiber with customized strength and length. Creating a circular, enviromental-friendly, low carbon emission steel fiber.

Stainless steel short fiber Main Features:

1. Near-zero carbon emissions: this is made from second life steel, significantly reducing its environmental impact, as it has an EPD value of 0,0436 kg CO2 e/kg.

2. Ultra dense fibre network: Thanks to the fibres’ high aspect ratio, a count of up to 160.000 fibres/kg avg. within the concrete matrix can be achieved. This leads to enhanced crack control and post-cracking ductility, while the high tensile strength ensures that steel fibres can withstand high stress without breaking.

3. Driving a circular economy: Made from the tyre cord of end of-life tyres, the steel fiber repurposes steel to reduce landfill waste, conserve valuable resources, and support a sustainable, closed-loop economy.

4. Maximized benefits of steel fibre reinforcement: delivers all the advantages of conventional steel fibres– cost-efficiency, enhanced durability, and improved safety –while offering the added benefit of sustainability.
