1diameter:3.0mm-12.0mm 2tensile strengh:1460-1870mpa 3used for concrete construction
Specification
1.Size:4.00mm-7.50mm2.Tensile strength 1370-1860MPA3.Standard:GB/T5223-2002, ASTMA421, ASTMA648, BS5896-80, JISG3536 or according to customers' requirements.
4.low-relaxation 1000hrs test passed
5 Application: non-concrete used in mining ,cable support .plug-ins such as cable-stayed and highways barriers.
6 Packing :Lining is water-proof plastic, outer layer is polypropylene woven bag on wood pallet or wood spool and according to customers' requirements.
6Advantages
a) Large difference in coating thickness: Electricity galvanized coating thickness average in 70-150g/m2, hot zinc coating thickness is generally about 300g/m2
b )Electricity galvanized has better bonding and surface condition .
c )Electricity galvanized by erosion slower
