Our range of standard screw conveyors has been developed to handle the majority of materials commonly associated with the agricultural, process and waste industries.

The use of standard designs and components enables us to offer fast delivery at a competitive price, backed up by a comprehensive after sales service. For unusual applications we can also design, build and install customised solutions to suit your particular requirements.



We understand that the materials used make a huge difference, that is why we only use the best for the job. The table below details all the materials used in our standard screw conveyors, but it is also worth noting that we can offer other materials at request.

Flights Carbon Steel / Stainless Steel
Centre Tube Carbon Steel / Stainless Steel
Drive Shaft High Tensile Steel
Non-drive Shaft High Tensile Steel
Trough Carbon Steel / Stainless Steel
Liner Carbon Steel / Stainless Steel
Thrust Plate Carbon Steel / Stainless Steel
Wear Plate Carbon Steel / Nylon 66
End Plates Carbon Steel / Stainless Steel
Lids Carbon Steel / Stainless Steel


Heavy duty conveyors are designed for transporting abrasive or other difficult materials in industrial or continuous processing environments.
