As brake sand for transport carriers
For transport companies, we offer brake sand with a grain fraction that meets the requirements of TL 989.0224/DBS 918 224 of Deutsche Bahn AG. Our quartz sand has a high quartz content of over 96% and is free of sludge. On customer request and especially abroad, we also supply other grain sizes for use as brake sand.
The brake sand is washed, sieved and fire-dried several times and is therefore free from organic substances.
We guarantee a high and consistent quality through continuous checks.
