The metal corrugated pipe is made of galvanized or non galvanized low-carbon steel, which is helically folded and engaged, and is used for post tensioned metal pipe with holes in prestressed concrete members. It has the advantages of light weight, good rigidity, convenient bending, simple connection, low friction coefficient and good adhesion to concrete. It is an ideal material for forming post tensioned prestressed tendons.
