What is a Post-Tension Slab? (with pictures)

Aug 13, 2020 · Many modern homes are built on post-tension slab concrete. Several methods exist for pre-stressing concrete, with post-tensioning being a very common one. Before a post-tension slab is poured, high-strength steel strands or cables, called tendons, are laid in a tight grid. These help support and give strength to the slab once it has cured.Welcome to buy prestressed concrete steel coil high prestressed concrete steel coil high tension steel coilprestressed concrete steel coil high tension steel coil ASTM A416 15.7MM PRESTRESSED CONCRETE STRAND 7 wire 9.3mm prestressed concrete steel wire rope for bridge High tension 12.7mm strand cables pc strand unit weight 2 wires, 3 wires pc strand 8.6mm for prestressing concreteTianjin Yiyuan Tongda Amperex Technology Limited - Steel prestressed concrete steel coil high tension steel coilTianjin Yiyuan Tongda Amperex Technology Limited, Experts in Manufacturing and Exporting Steel Coil, Sheet Section and 340 more Products.
