Packaging Details:Around 3 MTs per coil, and stripped by steel belts tightly, then warpped by PP woven clothes, and reinforced by supporting boards.
Unbonded PC strands are widely used in pre-tensioning or post tensioning prestressed concrete structure, like cable stay bride or PT slabs. 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.
Main Application:
Bridges, high-rise buildings, industrial facilities, warehouses, stadiums, sport complexes, containment tanks, airports, seaports, train stations, railways, subways, monorails, tunnels, dams, reservoirs, above and underground mining operations, foundations etc.
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
