Screws and conveyers

These can be used anywhere where granular material, powder material or dense material are conveyed, e.g. in:
  • Agriculture
  • Building industry
  • Chemical industry
  • Heating industry
  • Food industry

The fully automated production on automatic cold-rolling machines guarantees precise adherence to the dimensions required along with fully precise final products. Smooth plates with no welds guarantee a trouble-free flow of the material conveyed. Based on commercial experiences, we offer you the worms with diameter of 80 to 400 mm, as standard.

These sizes are ready to be supplied from our warehouse. We are also able to review special wishes of clients in our design department, and propose an overall concept within a short time. Our flexibility is conditioned by our long-life experience in the field of high-grade steel sheet treatment. All products from our factory are subject to a strict quality check and comply with quality regulations; all our products pass the final functional tests before they are handed over to a client.
