Galvanized Steel Frame

What is Galvanized Steel Frame

Galvanized Steel Frame is steel that has gone through a

chemical process to keep it from corroding.

The steel gets coated in layers of zinc oxide because this protective metal does not get rusty as easily.

The coating also gives the steel a more durable, hard to scratch

finish that many people find attractive.

For countless outdoor, marine or industrial applications, galvanized steel is an essential fabrication component.

One of the most common ways of making steel resist rust is

by alloying it with a metal that is less likely to corrode like zinc.

When steel is submerged in melted zinc, a chemical reaction permanently bonds the zinc to the steel.

Therefore, the zinc isn't exactly a sealer, like paint, because it

doesn't just coat the other metal. It actually permanently becomes a part of it.

The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel.

Zinc protects steel in two ways.

First, it is highly resistant to rust; iron, a major component of steel, reacts very easily with oxygen and moisture and will eventually disintegrate.

Secondly, the outer layer also protects the steel by acting as a sacrificial layer.

If, for some reason, rust does take hold on the surface of galvanized steel, the zinc will get corroded first.

Galvanized steel frame can be found almost everywhere.

Many individuals live in steel frame houses, and buildings are often made with galvanized steel roofs.

There are multiple steel parts in cars that help protect them from the weather, and it's used in many marine applications due

to its ability to withstand the salt and the elements.

Besides being inexpensive, durable and effective, this metal is also popular because it can be recycled and reused multiple times.

Main Benefits

The Galvanizing is lower in first cost than many other commonly specified protective coatings for steel.

Even in cases where the initial cost of galvanizing is higher than alternative coatings, galvanizing is almost invariably cheapest in the long term, because it lasts longer and needs less maintenance.

The life expectancy of galvanized coatings on typical structural members is far in excess of 50 years in most rural environments, and 20 to 25 years plus, even in severe urban and coastal exposure.

Galvanizing is carried out to Australian / New Zealand Standard 4680, and standard, minimum coating thicknesses are applied. Coating life and performance are reliable and predictable.

A galvanized coating has a unique metallurgical structure which gives outstanding resistance to mechanical damage in transport, erection and service.

Galvanized coatings corrode preferentially to steel, providing cathodic or sacrificial protection to small areas of steel exposed through damage.

Every part of a galvanized article is protected, even recesses, sharp corners and inaccessible areas.

Galvanized coatings are assessed readily by eye, and simple non-destructive thickness testing methods can be used.
