Here you will find everything you need to know about ropes and cables. What is the difference between a wire, strand and a rope? Which rope constructions do exist? What is meant by lay directions? What is the effect of stretching? What materials are available? What is a coated rope and what is it required for?
The lay direction indicates the direction in which the outer wires (outer strands) of the strand (cable) are laid around the center wire (core strand).
Strand in S-lay – left hand lay direction of wires.
Strands in Z-lay (lright hand ay direction of wires).
Steel cables with right hand ordinary lay (sZ).
Steel cables with left hand ordinary lay (zS).
Steel cable with right hand langs lay (zZ).
Steel cable with left hand langs lay (sS).
“S-lay” means: the outer wires (outer strands) are laid in left direction around the center wire (core strand).
“Z-lay” means: the outer wires (outer strands) are laid in right direction around the center wire (core strand).
Furthermore, a distinction is made between ordinary/regular lay and langs in the stranding (see figure). As standard, Carl Stahl Technocables delivers the steel cables in right hand ordinary lay (sZ).

Are high temperatures or good sliding properties required of your steel wire rope? Then we use special materials for coating of the steel wire rope. For example, we recommend FEP/PTFE for temperatures of between -190°C and + 205° C.
We can also offer PA6. PA6 is stiffer than PA12 and is therefore not suitable for pulleys. However, PA6 has better sliding properties and is therefore highly suitable as a guide cable for example.
Depending on the application, the appropriate coating material is used. Don’t you know which wire rope coating is the right for your rope application? - We're glad to help you finding the right material. Contact us directly
With Carl Stahl TECHNOCABLES, you will find the right steel cable to meet your requirements.
Contact us directly for your individual cable solution. We can recommend suitable steel cables for your purposes. The service life of strands and cables depends on many factors:
Testing until cable breakage
Test stop when the number of test cycles has been reached
The standard wires for steel wire strands and cables are made of galvanised steel or stainless steel 1.4401/ AISI 316. Galvanised wire offers sufficient corrosion protection for many areas of use. If the steel wire cables and strands are to be used in highly corrosive media, we recommend stainless steels.
In order to meet your special cable requirements, we also produce cables using other materials. In addition to the standard materials, stainless steel and galvanised steel special materials are also used, such as the following for example:
Brass | Copper | Titanium | Tantalum | Monel | Inconel | Hastelloy
For the jewellery industry Carl Stahl TECHNOCABLES produces cables and strands in:
Gold | silver | platinum | palladium
