Galvanized mild steel wire sheathed in a PVC jacket — two independent barriers between the steel core and everything the site can throw at it.

PVC coated GI wire starts as galvanized mild steel wire — already protected by its zinc layer — and adds an extruded PVC jacket over the top. The zinc guards the steel electrochemically; the PVC keeps water, salts and soil chemicals away from the zinc.
The result is a dramatically longer service life in exactly the conditions that destroy bare wire: permanently submerged works, tidal and coastal zones, and ground with aggressive chemistry.
What IS 16014:2024 itself says the PVC jacket is worth. The standard rates each coating system by how corrosive the site is, using the ISO 9223 categories C2 to CX.
| Site category | Bare, heavy zinc | Bare, zinc–aluminium | PVC over zinc–aluminium |
|---|---|---|---|
| C2 · low Rural areas and small towns, dry or cold zones | 25 years | over 50 to over 120 years | — |
| C3 · medium Towns; tropical sites with low pollution; coast with little salt | 10 years | 25 to over 50 years | over 120 years |
| C4 · high Industrial areas; coastal sites without salt spray; tropics with medium pollution | not offered | 10 to 25 years | 120 years or more |
| C5 · very high Heavy industry; coastline and sheltered shore positions | not offered | not offered | 120 years or more |
| CX · extreme Very wet tropics with heavy pollution; coastal and offshore, salt spray | not offered | not offered | over 120 years (zinc–10% aluminium core) |
Not offered means the standard lists no bare-wire option for that category: the PVC jacket is the only system it gives. Working life, as IS 16014 defines it, assumes properly designed and built works with normal maintenance. Permanently submerged and abrasive river works are not tabulated — life there is agreed for the project, and PVC is the usual answer.
| Wire | Bare GI — est. life | With PVC | PVC coated — est. life |
|---|---|---|---|
| 2.70 mm core Hot-dip galvanized, 260 g/m² zinc | 15–20 years | 2.70 / 3.70 mm, galvanized + PVC | 30–60 years |
Agarwal Gabions estimates for typical conditions, from our PVC wire brochure — not IS 16014 values. Five to ten times the life of the same wire left bare, and longer still where the wire is inspected and repaired.

From our PVC wire brochure — what the jacket does that zinc alone cannot.
The PVC jacket keeps water, oxygen and salts off the zinc, so the zinc is not consumed. Bare GI wire can show rust within 5–10 years; the jacketed wire keeps it out.
On bare wire, water collects at the twists and joints and rust starts there first. The smooth sheath sheds rain and humidity from every link.
PVC resists chemical attack in buried and submerged ground — the reason it is the usual choice for river training work, especially in Assam.
A stabilised compound that does not crack or weaken in the sun. In a filled gabion most of the mesh is shaded by stone anyway.
A cut or scuffed sheath can be repaired in the field before corrosion starts — no replacement needed.
Green, grey, brown, blue and more. No sharp edges or snags; cooler than bare steel in strong sun and no cold-burn in winter — right for fencing near people.
Anywhere the wire will be wet for good, meets salt or chemicals, or cannot be reached again once the job is built.
Gabions, revet mattresses and sack gabions that sit in flowing water and moving bed load. Submerged zinc is consumed far faster than zinc in air, which is exactly what the jacket stops.
River applications →Units that are meant to stay under water for their whole life and cannot be inspected once the river is back.
Scour applications →Salt water is the most aggressive condition these products meet. On the coast it is PVC over galvanized wire every time, and at C5–CX sites IS 16014 offers nothing else.
Coastal work →Polluted air, acidic mine water and chemical run-off attack bare zinc quickly. The standard offers no bare-wire option at the most aggressive categories.
Industrial applications →Reinforced soil facia units and walls in contact with wet fill, lime-stabilised soil or concrete, where the wire cannot be seen or reached again.
Facia units →PVC chain link for homes, schools, parks, tea gardens and resorts: longer-lived, safe to touch, and in the colour you want.
Chain link fencing →Green or grey sheathing that recedes into planting and stone, on walls that are meant to be looked at for decades.
Landscape gabions →The sheath insulates: cooler to the touch in plains summers, and no cold-burn from bare steel on high-altitude sites in Sikkim, Arunachal and Bhutan.
Where we supply →Weaving gabions and chain link fencing, fence line and binding wire, vineyard and orchard trellis, gardens and cloth drying lines. See PVC coated wire uses and which size.

Yes. PVC coated wire, plastic coated wire, vinyl coated wire and PVC coated iron wire are the same product: galvanized steel wire in a PVC jacket.
Strictly 7217 90 99, though many invoices use 7217 20 10; both carry 18% GST. Woven into mesh or gabions it becomes 7314 42. See HSN codes and GST.
IS 16014:2024 (Annex B) rates PVC over zinc–aluminium wire at over 120 years in a medium-corrosivity (C3) site, against 10 years for bare heavy-galvanized wire in the same site. At the most aggressive categories (C5 and CX) the standard lists no bare-wire option at all. For PVC over heavy-galvanized wire, our own estimate is 30–60 years on a 2.70 mm core — five to ten times the bare wire. See the full table.
Heavy-galvanized (zinc to IS 16014 Table 8) is our standard and suits most river, slope and fencing work. Choose a zinc–aluminium core for coastal, industrial or long design-life works, or where the tender calls for it: that is the combination IS 16014 rates at over 120 years, and it gives a tougher metal behind any cut in the jacket.
Nominal 0.50 mm with a minimum of 0.40 mm, extruded over the galvanized core. On a 2.70 mm core that gives a finished diameter of about 3.70 mm — the figure normally written as 2.70/3.70 in a specification.
The two protect against different things. Zinc protects the steel electrochemically; the PVC keeps water, salts and soil chemicals away from the zinc so it is not consumed. In permanently submerged, tidal or chemically aggressive ground that combination lasts far longer than either alone.
Not structurally. Standard PVC colours are available on request — grey and green are the usual choices where the works should recede visually.
