Our Durawall coastal spec concrete sleepers have hot dipped gal reo in each one. Great for installations close to the ocean, rivers or canals. The reo is sourced and galvanised in Australia. Each piece is cut from black steel and individually galvanised, so the ends are coated. It costs more, you can see our current pricing here, however it is better for longevity. We currently have an order for over 3000 units for a coastal development.
