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.
We manufacture to your project's drawing and governing standard. Typical parameters we supply against:
| Parameter | Available options |
|---|---|
| Core wire | Galvanized mild steel wire |
| Coating | Extruded PVC over the galvanized core |
| Core diameter | To project specification |
| Finished diameter | Core plus nominal PVC thickness, to specification |
| Colour | Standard PVC colours available on request |
| Typical use | Gabions, revet mattresses, fencing, river training works |
| Raw material | Procured to ISI standards from verified manufacturers |
| Quality system | ISO 9001:2015 certified (Cert. No. 305024011282Q) |
PVC is widely specified for river training work globally — including across Assam.
PVC resists harsh chemical interactions in buried or submerged areas — which is why it is widely used in river training work globally, especially in Assam.
Submerged gabions and mattresses lose zinc fastest. The PVC jacket slows that attack dramatically, extending design life.
A second barrier means less frequent intervention on structures that are expensive and disruptive to access once built.
