Welcome to SteelPhalt - Making Roads Safer

SteelPhalt has been developing and manufacturing high performance asphalt products for the UK roadmaking industry since the 1960's. Based in Rotherham, South Yorkshire, SteelPhalt is ideally located to source slag cost-effectively from the surrounding steel industry - a sustainable way of making asphalt since at least 95% of the product is recycled.

With a reputation for first class products matched by a commitment to innovation and sustainability, SteelPhalt works in partnership with councils, local authorities and contractors nationwide to deliver durable roads for a sustainable world.
