Galvanized steel strand is a product composed of multiple galvanized steel wires twisted together. It is usually used to bear tension and can be used for overhead use and as a pull wire.
The stranded wire models are JG1A, JG2A, JG3A, JG4A, JG5A.
Features
1.low cost and ease of production makes galvanized steel wire ideal for mass produced corrosion resistant wire products.
2.To increase its corrosion resistance, galvanized steel wire strand is exposed to a galvanizing procedure.
3.Good reliability and high strength
Application
Galvanized steel strands can be used as earth wire, stay wire, messenger wire, core wire or strength member, etc.
Construction
Concentrically stranded galvanized steel wire strand.
Products are divided into five grades according to the nominal tensile strength: grade 1, grade 2, grade 3, grade 4, grade 5, of which grade 5 has the highest strength.The structure has 1×7, 1×19 and 1×37 roots.
