Import 1x7 Pc Strand, Prestress Concrete Steel Strand — Buy in Bulk from Supplier in China

Nantong Zhengyang Steel Rope Co., Ltd. supplies 1x7 prestressed concrete steel strand, a high-strength wire product used in post-tensioned and pre-tensioned concrete construction. The strand consists of six outer wires helically wound around a central core wire, creating a compact cross-section that delivers high tensile capacity. Available diameters range from 0.8 mm to 15.7 mm, with surface options including galvanized and uncoated finishes to suit different environmental exposures.

This type of strand is manufactured to meet standard prestressing specifications such as ASTM A416 or EN 10138, which define minimum tensile strength, elongation, and relaxation properties. Typical tensile grades for 1x7 strand include 1860 MPa and 1770 MPa, with stress-relieved or low-relaxation treatments applied to control long-term prestress loss. The galvanized variant provides corrosion resistance for applications exposed to moisture or de-icing salts.

Primary buyers include civil engineering contractors, precast concrete manufacturers, and bridge construction firms who require reliable prestressing materials for beams, slabs, and structural elements. The supplier is based in Zhuhang Town, Nantong, Jiangsu Province, a region with a well-established steel wire and rope manufacturing base. Trade terms, certifications, and minimum order quantities should be confirmed directly with the supplier before placing an order.
