Products Description
SHENWEI's premium 6×7+FC Galvanized Steel Wire Rope is custom-engineered to deliver exceptional structural stiffness, industry-leading abrasive wear resistance, and long-term corrosion protection for global industrial engineering. Characterized by its robust 6-strand layout with 7 thick individual wires per strand, this construction provides a significantly larger outer wire diameter than conventional multi-wire cables. This heavy-duty shielding makes the 6×7 structure the ultimate choice for environments prone to intense physical scraping, heavy friction, and severe mechanical drag.
Featuring a high-durability Fiber Core (FC), this rope offers an ideal blend of robust linear strength and flexible structural recovery, absorbing dynamic tension spikes seamlessly. Shielded by an advanced, uniform galvanized zinc coating, it is built to survive prolonged exposure to rain, coastal salt air, and harsh soil contact. Available in a comprehensive diameter spectrum from 3mm up to 32mm (with 20mm featured as a heavy-duty flagship size), and offered across multiple high-tensile grades including 1570 MPa, 1770 MPa, 1870 MPa, and 1960 MPa, SHENWEI's factory-direct 6×7+FC rope is the reliable lifeline for general rigging, agricultural guy lines, marine pulling winches, and boundary protection projects.

Steel wire rope production process
Step 1: Making the wire. The raw material for wire products is supplied by steel mills. The billets are made into wire rod through the hot rolling process.
Step 2: Surface treatment of wire rod. Rust and scales are removed from the wire rod surface. The wire rod surface coating facilitates drawing.
Step 3: First drawing. After the descaling and surface coating treatment, the wire rod will go to the first drawing, where it will be drawn to the required diameter, resulting in a semi-finished wire with mechanical properties suitable for the application. Then the wire will be heat-treated to facilitate the drawing.
Step 4: Drawing again to obtain the wire of the required diameter.
Step 5: Make strands, combine the drawn steel wires into one strand.
Step 6: Combine the strands to for a rope according to the structure of the wire rope.
