Galvanised steel has a variety of uses across different industries ranging from air-conditioning panels to feeder troughs. It provides quality protection inside and out.
Galvanised steel is produced when a thick layer of zinc combines in a metallurgical reaction with zinc. The outer layer is 100% zinc; and, since the reaction between zinc and iron is a diffusion reaction, the crystalline structure forms perpendicular to the steel surface.
What is Galvanised Steel?
Galvanised Steel is produced by hot dipping steel in a zinc coating solution. The coating solution protects the steel from particle corrosion and general abrasion. This type of steel is ideal for use in marine applications, as the surface is salt resistant and also able to withstand extreme weather conditions.
Galvanised Steel can be used in construction environments up to 200 degrees Celsius. The measure of how galvanised a steel sheet is ‘weight per surface area’ of zinc.
This type of steel is also highly workable, making it perfect for a range of uses. Galvanised Steel sheet can be pierced, pressed, sheared, drawn on, bent and welded according to many project requirements.
What are the Benefits of Using Galvanised Steel?
Due to its resistance to natural and chemical corrosion, Galvanised Steel has been known to be highly reliable in both coastal and city regions. This product, unlike some other types of steel, is recyclable.
Galvanised Steel is highly sustainable, as its unmatched protective coating adds to its longevity. This factor makes it a desirable option for both industry and urban projects. It is particularly popular in the construction of mass infrastructure.
Due to its versatility, Galvanised Steel is used in a variety of applications across the globe.
1. Low Upfront Costs
The cost of applying a painted coat to steel has risen dramatically in the past few decades. As a result, the galvanising process has become increasingly popular in a variety of industries.
2. Low-level Maintenance Costs
Due to it’s protective coating that is both abrasion resistant and largely chemically resistant, Galvanised Steel is able to used with very little ongoing maintenance. Its longevity means that it can be found in various remote areas, where the cost of ongoing maintenance is a serious consideration. Over the course of its lifetime, the limited costs of maintaining Galvanised Steel make it an affordable option.
Galvanised Steel is expected to have a lifetime of at least 50 years in most rural environments; however, even in harsh conditions and climates such as severe coastal areas, it has a lifetime value of 20 to 25 years.
Due to strict regulation regarding galvanised coating, there is a reliable minimum coating thickness required in Australia and New Zealand. As a result Galvanised Steel is a predictable and standardised product.
5. A Tough Outer Coat
Due to its unique metallurgical structure, Galvanised Steel provides an excellent tough coating that protects the product over the course of its lifetime as well as during shipping and transport.
6. Protection For Damaged Areas
Galvanised coats corrode preferentially to steel, cathodic and sacrificial protection is provided to small areas of steel exposed to damage. As a result they need less maintenance over the course of their lifetime.
7. Complete Protection
Because the galvanising steel coats evenly on all areas, including recesses, corner and angles, Galvanised Steel is comprehensively protected from abrasion and general wear and tear.
8. Easy To Inspect
Galvanised Steel can be assessed by eye, as well as by easy non-destructive thickness testing methods. Due to the coating process, if the coating looks continuous it will likely be that way all the way through.
9. Fast To Install
Given that Galvanised Steel already has a protective coating, no time is lost in construction preparing, painting or inspecting. The result is that assembly can happen reliably at a fast pace.
10. Easy To Apply A Full Protective Coating
Galvanising is not dependent on weather conditions and applies a thick even layer. This makes it a highly reliable coating option.
What Are The Applications of Galvanised Steel?
There are several uses for Galvanised steel. Due to its excellent resistance and workable properties, it is used in a variety of conditions:
- In underwater environments, especially where water temperatures vary;
- Coastal or marine environments;
- Underground soil-based environments;
- On placements where chemical contact is inevitable;
- Placements where contact with other building materials is inevitable.
Some typical applications include:
- Cable Trays
- Air-conditioning ducts
- Rendering Mesh
- Feeder Troughs
- Air-conditioning Panels
- Meter Box
