How long can Renault pads last? Comparison of service life of galvanized vs. high alumina vs. PVC coating

Analysis of Renault pad anti-corrosion technology: full disclosure of different materials and service life
The application of Renault pads in engineering is becoming increasingly widespread, and one of their important advantages is their long service life. So, how long can it last? Is it true that it can last up to 50 years as rumored? This article will systematically analyze the anti-corrosion technology and material selection of Renault pads, taking you to a comprehensive understanding of their durability secrets.

1、 Corrosion resistance and service life of different materials

Cold galvanized wire
Features: Smooth surface, bright white color
In fact, the zinc layer is extremely thin, about 10g/㎡. It is prone to oxidation and blackening when exposed to air for a long time, and is more prone to rusting in soil or water flow environments.
Expected service life: about 1 year

Ordinary hot-dip galvanized wire
Features: The surface is not as smooth as cold galvanized wire
The zinc layer is about 45g/㎡, with better anti-corrosion performance than cold galvanizing, but still limited.
Expected service life: approximately 2 years

High zinc wire
It belongs to a type of hot-dip galvanized wire, but the zinc layer is thicker, about 245g/㎡ (adjusted according to the wire diameter).
It is currently a widely used material with high cost-effectiveness, significantly extending its service life without human damage.

Zinc aluminum alloy wire (Galfan)
By galvanizing aluminum alloy on the surface to achieve stronger anti-corrosion effect, it is divided into two types based on aluminum content: 5% aluminum and 10% aluminum.
Excellent anti-corrosion performance, rumored to have a service life of up to 50 years. Although it is difficult to fully verify in practice, it should be used in suitable environments for more than 20 years without any problems.

Plastic coated wire
The outer layer of the steel wire is coated with plastic, and the thickness of the plastic layer is usually 0.5-1mm.
According to the plastic material, it is divided into two types: PE and PVC:

PE: The anti-corrosion improvement effect is average

PVC: can extend the service life by about 5-7 years
The plastic coating treatment further enhances the corrosion resistance, and the price is correspondingly higher.

2、 Summary

The anti-corrosion ability and service life of Renault pads depend on the selected material and its surface treatment process. From ordinary cold galvanizing to zinc aluminum alloy and then to plastic coating treatment, different specifications correspond to different anti-corrosion grades and price ranges. When selecting engineering materials, the most suitable material type should be chosen based on specific environmental requirements and budget.
