PC strands are widely used in pre-tensioning or post tensioning prestressed concrete  structure. It is characterized by having no need of room for future expansion and grout, convenient construction, material saving and easily bending etc.

We could offer international standards like ASTM A416, BS 5896, EN 10138 etc.

Coil weight is suitable for cutting around 1-3 tons, other coil weight available as well. Normally strand placed as eye-to-sky when loading. Each coils packed with steel strips and woven bag to protect the strand from damage.


TRS is also capable of producing epoxy-coated strand, galvanized PC strand, PE zinc-coated strand, indented PC strand, spiral-rip PC strand, for various applications.
