Product Description

PC Galvanized (Aluminum) Strand
Normal Diameter: 12.7mm, 15.2mm, 15.7mm, 17.8mm
Coils weight: 2.5-4.0MT / Coils

This product is applied to stay cables, main cables and anchoring systems of bridge cable structures, external cables of arch bridge slings and other pre-stressed structures that do not directly contact with concrete mortar. we have participated in the construction of many large cable-stayed bridges in China. The diameter of this product is 12.70mm, 15.20mm, 15.70mm, 17.8mm and it is low relaxation pre-stressed strand. The coated steel wire is further drew and stabilized by heat treatment, then intermediately made to galvanized (aluminum) strand. The strand has no binding, and won't get loose after cutting. The surface coating is uniform and continuous, and the straightness is good. The mechanical properties meet the requirements of ASTMA416, prEN10138, NFA35-035 and other international standards. The strand has a uniform lay length, which is 12-16 times of the nominal diameter. The coating mass of the single wire is 190~350g/m2. The aluminum content of the zinc-aluminum alloy steel strand coating is not less than 4.2%. The coating adhesion is strong, and the coating is uniform without leakage. The amount of zinc can meet the requirements of A475-09, level A.
