Description

Previously, when introducing iron wire, we mentioned the galvanizing process, which provides corrosion resistance. PVC coated iron wire also offers corrosion resistance, making it suitable for use in humid environments, coastal areas, and even in contact with acids and alkalis, extending its service life. It maintains its shape at high temperatures and resists cracking at low temperatures, making it suitable for outdoor use.

The difference between PVC coated iron wire and galvanized iron wire

Many users are wondering about the differences between PVC coated iron wire and galvanized iron wire. See below:

Structural Differences: Galvanized wire is based on ordinary iron wire, galvanized to provide corrosion resistance. PVC-coated wire is based on galvanized iron wire with a PVC plastic coating, making it more widely applicable.

Performance Comparison: Galvanized wire has limited rust resistance and is susceptible to corrosion in acidic soils. It can break easily after repeated use and should not be used in conductive environments, making it more suitable for dry environments. PVC coated iron wire offers excellent acid and alkali resistance, and the coating enhances wear resistance. It has a tensile strength of 1670-1770 MPa, and the PVC layer provides high insulation properties, making it suitable for wire tying and is suitable for harsh environments such as marine engineering and chemical fencing.

Additionally, there are differences in application scenarios. After explaining the performance characteristics of the two types, users will be able to determine which wire product is best for the right environment.

Service life of PVC coated wire

As I've just explained, PVC coated iron wire actually has a longer lifespan than galvanized wire. When used outdoors, PVC coated iron wire generally lasts 8-12 years. If protected from UV rays, it can last up to 15 years. Of course, in actual use, mechanical damage, installation process variations, and other factors can affect its lifespan. Therefore, when using PVC coated iron wire, avoid contact with sharp objects, regularly remove surface dirt, and repair any damage to the coating immediately. If exposed to long-term loads, check the wire tension annually to prevent overload fatigue.

What precautions should be taken when using PVC coated iron wire?

Scratch Resistance: While not as fragile as glass, handle with care and avoid throwing or dragging the wire.

Connection Protection: The wire should be bent at a 90° angle or greater. Excessive bending can cause micro-cracks in the coating. PVC sheathing should be installed at the joints to eliminate safety hazards.

Tool Usage: Avoid using high-temperature equipment when cutting, as the PVC coating can melt and crack when exposed to heat.

Environmental Restrictions: In rainy weather, contact with water at the bonding area can weaken adhesion.

Inspection: PVC coated iron wire after installation, inspect the coating for scratches and cracks, ensure there are no exposed metal at the connection points, ensure uniform tension, and ensure there is no shaking when manually pressed.
