Polywire or polytape for cattle, horses, or steel line

Updated: October 2026

You are choosing a conductor, and the amazon.co.uk photo is a round twisted reel while the title says rope or even tape. Polywire or polytape is a shape decision before it is a brand decision. Polywire is the twine, polytape the flat ribbon, polyrope the thicker round line, and high-tensile steel the permanent wire. Every reel on the [electric fence wire comparison](/hub/fencing-and-wire/electric-fence-wire) sits in the twine column, so tape or rope means leaving the set. Horse welfare is on [electric fence wire for horses](/hub/fencing-and-wire/electric-fence-wire/sub/electric-fence-wire-for-horses).

Four conductors, four jobs

Polywire is light twine with a few stainless filaments and higher resistance than steel. Polytape is flat, so stock see it sooner and wind works on that face. Polyrope is round, often about 5 mm to 6 mm, visible and less of a sail than wide tape. High-tensile wire is the lowest resistance. AHDB points to about 2.5 mm steel on a long run and about 1.6 mm on a shorter one. Other sellers' six-strand polywire is often near 4 ohms per metre. These nine reels print none. Use polywire for a moved cattle or sheep strip, tape or rope when stock must see the line, and steel for a grant fence.

When polywire is enough

AHDB calls polywire the cheapest plastic conductor for strip grazing, if the pulse is there and the bottom wire stays out of the grass. A 200 m to 500 m reel matches a line you will move. Entry prices are about £12 to about £14, and 500 m reels sit about £23 to about £28. That is twine money, not tape. Red and white, or Rutland white/yellow, is not a 20 mm ribbon. Agrisellex says tape is easier to see and polywire is cheaper and lasts longer. That is a shop note, not a test of these ASINs. Nine strands on ohbien's 1,000 m reel stay polywire. Length and the missing ohms are on the buying guide.

Tape, rope, and wind

Tape wins on the first approach and loses when a wide ribbon flaps. UK Countrystore says 20 mm in wind, because 40 mm can damage the conductors, and 40 mm only where it is clamped. Rappa recommends 12 mm for temporary lines and 20 mm to 40 mm for more permanent lines, and says rope or braid copes with wind better. None of these reels has a tape width, so that advice does not apply to 2 mm polywire. Rope is the horse line where tape would sail.

Steel, and what this Amazon set cannot be

Steel carries a pulse further than any twine here, and it is the wrong fence for a horse that may gallop into it. GOV.UK FG3 wants a mains energiser, at least four plain steel or high-tensile wires, a fence at least 1.05 m, and straining posts. Polywire does not meet that line. APACALI says polywire and rope, one bullet says tape, and the diameter row says 2 mm. LDHHYH's included line says rope on a 6-strand title. If the photo is twisted twine, buy it as twine. A Willis price for 5 mm rope, about £56 for 200 m, is not in this set. Horses need tape or rope. A grant line needs steel.

Common questions

What is the physical difference between polywire, tape and rope?
Polywire is a narrow twisted twine with stainless filaments, light and higher resistance. Polytape is a flat ribbon, easier to see and more affected by wind. Polyrope is a thicker round plastic conductor, often about 5 mm to 6 mm, visible and less of a sail than wide tape. Steel is a separate family again, plain high-tensile wire for permanent lines.
When is polywire the right buy for cattle or sheep?
It fits a short temporary strip that cattle or sheep already respect, where you will move the line and you do not need the animal to see a wide band. AHDB treats it as the cheaper plastic option, with fewer posts than steel and higher resistance, so the run should stay within what your energiser can hold. A horse, or any stock that meets an unseen wire at speed, needs tape or rope inside a physical fence.
When does wind make tape the wrong shape?
Wide tape flaps, fatigues the conductors and can saw on insulators. UK Countrystore points to 20 mm rather than 40 mm in a windy field, unless the wide tape is clamped. Rappa treats 12 mm as the temporary width and says rope or braid copes with wind better than tape. If your site is exposed, rope is the visible line that does not present a flat face to the gale.
When is rope the better horse line than tape?
Rope is the better horse conductor when you need visibility and the field is open enough for tape to sail. UK Countrystore splits it that way: tape for horses where wind is modest, rope where tape would catch the wind. Both are easier to see than 2 mm polywire. Rope named in a polywire title is not this rope.
Why is high-tensile steel a strong conductor and a poor horse fence?
Steel has the lowest resistance, so a long permanent run stays effective, which is why FG3 specifies it. It is also rigid and heavy. A horse that gallops into it can be cut or thrown in a way light twine may not match. Use steel for cattle or sheep boundaries and for grant permanent fences.
Does nine strand on the long ohbien reel make it tape or rope?
It stays polywire. The listing says 1,000 m and nine interwoven stainless wires, with a bullet that says 3 mm each, and it prints no tape width and no ohms. Nine filaments in a twine are not a 20 mm ribbon and not a 5 mm rope. APACALI's tape bullet and LDHHYH's rope wording have the same limit: read the diameter row and the photo.
