Vertically Integrated Polymer Manufacturing
From raw polymer chemistry to finished product. Five UK factories, seven specialist divisions, and over 36 years of engineering materials that perform in the world's toughest environments.
Engineering Excellence Since 1988
Rosehill Group was founded in Sowerby Bridge, West Yorkshire in 1988. What started as a specialist polymer company has grown into a vertically integrated manufacturer operating seven divisions from five dedicated factories — all within the Calder Valley. We formulate our own chemistry, manufacture our own products, and control quality at every stage.
Today our products are installed in over 50 countries. We recycle more than 350,000 end-of-life tyres each year, transforming them into high-performance systems for highways, railways, playgrounds, and defence. Vertical integration means we can develop, test, and deliver faster than anyone else in our sector.
Five Factories. One Valley.
All five manufacturing sites are located within the Calder Valley, West Yorkshire — giving us tight quality control and fast turnaround across every product line.
