post-tension tube making machine

Post-tensioning corrugated metal ducts are the most economical means to create a void for the tensile elements. These thin-wall galvanized corrugated 28ga / 0.38mm ~ 24ga / 0.6mm steel metal ducts also provide a secondary corrosion protection with excellent bond behavior between tendon grout and concrete.

This machine is comprised of two machines, one is for forming round ducts and the other is for forming oval shape from round ducts.
This post tensioning corrugated metal duct machine is suitable for both indoor and site work.
