One of the most common products formed from steel rods are towing wire. steel rods in different sizes are used to produce towing wire. towing wire is a combination of wires with different sizes which has a proper strength against fatigue and abrasion.  if a strand has a few large wires, it will have more strength against abrasion. although, in comparison with strand which has a lot of small wires, the fatigue strength will be less. the central rod strand called "cable core". cable core can be non-metal and produce more flexible cables. however, cables with steel cable core have more tensile strength. usually, hemp strand is used to produce flexible cable.  what are different types of towing wire?

- single size cable: main strand has unique size wires which twist around one central wire.

-Seal towing wire: in this cable, external large wires and internal small wires twist around a wire core. this arrangement stablishes a high abrasion strength.

-Filler towing wire: small wires fill up empty space between large wires. This arrangement establishes high abrasion strength and high flexibility-

- Warrington towing wire: small and large wires are respectively in external layer. this arrangement has high flexibility and strength, but low abrasion strength.  many of common towing wires use combine of these types.
