Wire Rope design and manufacture.

Wire ropes are made of high-strength cold-drawn wires. The wires 1 area helically wound around the core 2 to form a strand, 3 the strands are then twisted around a steel core 4 to produce the finished ropes. 5 The length of lay L is the measuring value for the pitch of a lay.

The fill factor is the ratio between the metallic cross sections and the total rope cross section.

The metallic cross section (mm2) is the sum of the cross sections A of all wires in the rope. 

The nominal strength is the tensile strength of the wire in newton (N) per square millimeter

The calculated breaking strength is the product of the metallic cross section and the nominal strength of the wires.

The minimal breaking strength of the rope is the product of the calculated breaking strength and the spinning loss factor.

The actual braking strength is determined in a destructive test of the entire rope leg. 

The spinning loss factor is a correction value which takes into account the difference between the calculated and the actual breaking strengths. 


In combination with other architectural products like end connectors and tensional options, our wire ropes can be used in a wide variety of ways: railing infill, protective nets, safety nets, barricades, fences, zoo enclosures, aviaries, suicide prevention, façade greening, artwork, ball nets, stair wells, skylight protection, fall-stop nets, bridge protection, machine protection, etc.
