Sectional Flighting & Screws

Sectional flighting is manufactured from steel plate and formed into a helix. Sectional flighting is available in heavier thicknesses than helicoid flighting and used in more abrasive applications. Sectional screws are manufactured by mounting sectional flighting on a center pipe, butt welding each flight together and fastening by intermittent welds.
