About Us

SteelPhalt has been developing and manufacturing high performance asphalt products for roadmaking in the UK 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.

Steel slag has inherent properties which make it ideally suited for use as a surface course for roadmaking:

  • exceptional strength and durability of steel slag extends the life of the road and lengthens road maintenance intervals
  • steel slag achieves high skid resistance and maintains it throughout the whole life of the road as a result of its capacity to regenerates its surface roughness over time
  • avoids use of quarried materials, and avoids landfill of residual slag product

Through detailed knowledge and experience of working with our roadmaking materials, we are able to offer various products to suit different application types.

Proud to Be Part of the Yorkshire Community

SteelPhalt has a strong tradition of involvement with the local community. From fundraising for our local hospice, supporting road safety initiatives in schools to sponsoring youth sports teams, SteelPhalt certainly gets out and about in the community. In addition to helping to make our region's roads safer through the products we supply, we like to get to know the people who live in our area too. So, each year SteelPhalt is involved in a range of initiatives with the community.

We're proud to be South Yorkshire company and pleased to be able to give something back to the region.
