ADVANTAGES
-Primary advantages
Steel strand strictly in accordance with industry standard.
Weight of zinc layer per unit area 190-400 g/m
The zinc layer has strong adhesion, and the pre twisted galvanized steel wire undergoes a winding test. After 6 rounds of winding, the zinc layer on the spiral coil does not peel off.
The galvanized layer is uniform, and the galvanized steel wire sample that constitutes the steel strand is immersed twice (each time for 60 seconds) in a copper sulfate solution, without any bright deposition layer or orange
Adhesion of red copper.
The surface quality is qualified, and the galvanized steel strand has a continuous zinc layer surface without defects
USE
Bridge cables,Buildings for lifting and fixing tension components, and Prestressed structures that 7 Wire PC Strand Zinc Coated do not directly come into contact with concrete mortar.
