The PVC Coated Wire by SRK starts with a high-quality metal core, which can range from steel to aluminum, depending on the specific application requirements. The core wire undergoes a thorough cleaning and surface preparation process to ensure optimal adhesion of the PVC coating. This meticulous preparation guarantees a consistent and durable bond between the core and the protective PVC layer. https://www.srkmetals.com/pvc-coated-wire.php
