Galvanised Steel vs Stainless Steel

Choosing the right steel for the job can come down to a number of factors like the type of work, the location and the budget. While galvanised steel is generally cheaper, stainless steel is stronger. Both options have the same goal of protecting against corrosion and rust.

To help you understand the differences between the two, the Adelaide based team at Normetals in Ottoway is here to help—have a read of our summary on galvanised steel and stainless steel below.

What is galvanised steel?

You are probably most familiar with galvanised steel as part of a home build or renovation. It is steel covered with a layer of zinc to protect it from rusting. Many galvanised steel products are common hardware items like nuts and bolts, screws, nails, hinges and pipes but it has broader applications for larger jobs. The steel can be welded before it is galvanised or re-galvanised if required to be welded after. The zinc coating forms a crucial barrier between moisture and the steel which also makes it very useful in a number of other ways.

What is galvanised steel used for?

In addition to smaller items, galvanised steel can also be used in major construction products like beams, pipes, sheets and plates. Gates, fencing, posts and wire can all be made from galvanised steel to give the products added protection from the forces of nature that can degrade exposed steel over decades.

What is stainless steel?

Stainless steel is steel made with 10 per cent chromium which is an alloy added to help with rust protection. Stainless steel is very strong and its resistance to corrosion makes it a popular choice in domestic and construction products. While it is more expensive than galvanised steel, the finish is usually more aesthetically pleasing.

What is stainless steel used for?

You probably associate it with a kettle, fridge or dishwasher but stainless steel has a variety of uses. Because of its strength and resistance to corrosion, stainless steel is commonly used in construction. Many famous buildings around the world are made from stainless steel. One of the most famous examples is the Chrysler building in New York.

So which one should I choose?

Generally, galvanised steel is cheaper and easier to work with while stainless steel is stronger and more resistant to corrosion. It really depends on the job you are doing. If you are putting up fencing on a farm, you wouldn’t install kilometres of stainless steel fencing. If you are constructing a swing set and slippery dip for play equipment, you would use galvanised steel. If you’re building a pool fence, outdoor kitchen or barbecue area, using stainless steel would give you a much nicer finish and be more appealing to potential home buyers. The best thing to do is to speak to an expert.
