Knowledge.

Everything we know about screw conveyor flights, augers and the steels they are pressed from — written by the people who press them, not by a copywriter.

Start here

• Screw conveyor flights — what we press, in which sizes and grades.
• Sectional vs. helicoid — why constant blade thickness decides service life.
• Screw conveyor repair — replace the flight, keep the shaft.
• Earth auger flights — Hardox, Creusabro, manganese steel.
• Glossary — pitch, starts, hand, opening angle, DIN 15261.

The short version

We press sectional screw flights from Ø 40 to 3000 mm in plate from 2 to 60 mm, in about 25 steel grades, to DIN 15261 tolerances. Every flight is gauged before it leaves Edewecht. We have made over three million of them since 1980. We do not build complete conveyors — your fabricator welds our flights onto the shaft, and finds nothing to correct.
