What are the benefits of galvanizing?

1. Advantages of galvanizing

The purpose of galvanizing is to form a zinc protective coating on steel or iron parts. But why is this useful? What are the main advantages of galvanizing?

Block corrosive substances: The zinc coating on galvanized metal prevents corrosive substances from reaching the weaker underlying base metal. This extends the service life of the substrate, especially in demanding applications.

Rust prevention: Zinc plating significantly delays rust.

Create a sacrificial anode: The zinc coating is consumed by corrosive substances, so it provides protection for the metal underneath until it is completely used up. Even if the scratch penetrates the coating, the zinc will run out before the iron.

Durable: The zinc coating formed by galvanizing is tough and long-lasting, often providing protection for the underlying metal for decades.

Affordable: Galvanizing is a fairly simple and affordable procedure that provides significant benefits with minimal outlays.

Forming a thick coating: Although not suitable for all applications, galvanizing produces a thicker coating than, for example, electroplating.

2. the application of galvanized

The ability to prevent steel corrosion has made galvanizing widely used in a number of industries.

The most common application is galvanized steel for construction: hundreds of thousands of tons of galvanized construction steel are produced annually to make structures such as building frames, street furniture, fire escapes, ladders and balconies.

Galvanized steel is also common in the automotive industry, where it can be made into rust-resistant parts, including much of a car's "body in white" : its skeletal base. Bumpers, beams, frames and chassis can also be made of galvanized steel.

Rust prevention is an ideal feature in the telecommunications industry, where phone lines and electrical boxes are affected by these elements on a daily basis. Galvanizing helps to extend the service life of such articles.

3. with galvanized metal manufacturing

Galvanized materials can be widely used as galvanized metal sheets, suitable for sheet metal manufacturing processes such as bending and stamping, or galvanized metal bars, tubes and rods suitable for processes such as CNC machining.

Galvanized materials tend to be easy to process because the zinc coating is softer than the underlying steel.

Galvanized metal can also be welded, but zinc can give off dangerous fumes, so proper ventilation is essential. Paint is not particularly effective on galvanized steel or iron unless the material has been galvanized.
