45 years of experience in steel and plant construction for the stone and soil industry
We are a steel and plant construction company from the Münsterland region. Since 1978, our 130 employees have been planning, manufacturing and erecting plants and plant components for gravel plants, ready-mix concrete plants, asphalt mixing plants and gravel pits throughout Europe.
We offer complete planning of entire plants from the primary crusher to loading. With our own structural engineering department and many years of cooperation with all leading machine manufacturers in the stone and earth industry, we ensure optimum results. Our in-house forwarding department and our fitters operate throughout Europe. We also guarantee extremely short delivery times for repairs and spare parts thanks to our two-shift operation.
