At the core of plastic coated iron wire is its two-fold composition. The iron provides the wire with substantial tensile strength and resistance to deformation, making it an effective choice for facility fencing, scaffolding, and other structural applications. The plastic coating, typically comprised of PVC or polyethylene, offers a layer of protection that resists corrosion, rust, and other environmental factors. This means that the wire remains intact over time, even when exposed to harsh weather conditions.
