Differences between Galvanised and Stainless Steel
Difference between Galvanised and Stainless Steel:
Steel buildings rust naturally over time, which is why it is a good idea to invest in a protective solution to keep the metal from corroding. Being aware of the different solutions is vital to understand what’ll work for you. Two of the most common types of protective solutions used in fabrication projects are galvanised steel and stainless steel. They both have their pros and cons, and both steels have their different usages. That is why, in this blog, we will discuss the differences between galvanised and stainless steels, as well as which is the best option for you.
What is Galvanised steel?
Galvanised steel is steel which has a protective layer of zinc. This is accomplished through the use of hot-dip galvanising or electroplating technology. This protective layer helps to prevent your structure from rusting due to oxidation, and will ensure your structure doesn’t corrode. It also works well against rain and water, making it a great choice against the great British weather. The only downside to galvanised steel is that overtime it does wear away and will require maintenance of this.
What is stainless steel?
This is caused by chromium interacting with oxygen and forming a layer of chromium oxide. This layer prevents the steel elements from interacting with oxygen, preventing rust formation. Stainless steel is a much more difficult material to work with because it requires a lot more precision when heating and cooling the metal. However, stainless steel is extremely durable and will last a long time.
Galvanised vs Stainless Steel:
Price:
Galvanised steel is a lot cheaper than stainless steel due to the process of creating and welding stainless steel. However, galvanised steel does require you to spend some money overtime due to the maintenance of the layer of protective zinc. But when using galvanised steel, you won’t be anywhere near the amount you would for stainless steel as usually stainless steel is 3-4 times more expensive.
Aesthetic:
When deciding on the right metal for your structure, consider the look and feel. Because of steel's overall versatility, both metals are extremely customisable and can be turned into any design you desire. They can also be painted, giving them a completely unique appearance. However, stainless steel has a shiny, silver-like finish that gives it a slight advantage over galvanised steel's dull finish.
Durability:
Both of these materials are incredibly durable due to the overall nature of steel. However, the added elements inside stainless steel takes it slightly over the edge in terms of durability. This is what leads to the increased price of stainless steel.
Usages of stainless steel:
- Balconettes
- Canopies
- Staircases
- Outdoor Balustrade
Usages of galvanised steel:
- Walkways
- Cat ladders
- Railings
- Balconies
Despite, their individual usages, each of our bespoke fabrication projects can be completely customised to how you’d like it, including the materials used.
Our verdict:
We recommend galvanised steel if you're on a tight budget, but stainless steel for quality and longevity. However, the material only accounts for a portion of how your structure will look. This is because we believe that the experts you work with make the biggest difference in how your structure looks and feels. When you work with experienced welders who understand what you want, they will be able to make your vision a reality within your budget.
