However, one particular type of steel, namely galvanised steel, stands out due to its remarkable properties. So why galvanised steel? Let’s dive into the introduction of galvanised steel before we delve into answering this question.
Galvanising is a process which involves coating a layer of zinc over the surface of the steel. This process is carried out to protect the underlying steel from corrosion, thereby significantly enhancing its lifespan and durability. The protection is two-fold; the zinc layer shields the base steel from external corrosive elements, and in case there are any scratches or damages to the surface, zinc sacrifices itself by corroding first to prevent the rusting of steel.
Why galvanised steel is favoured over other types becomes clear when you consider its unique advantages. The corrosion-resistance that galvanised steel offers makes it an ideal choice for outdoor or harsh environments where other materials would deteriorate quickly. It can effectively withstand factors like rain, moisture, sunlight and chemicals, making it a highly reliable option for applications such as roofing, outdoor sculptures, guard rails, and more.
Another key reason why galvanised steel is preferred is due to its cost-effectiveness. While the initial cost might be higher than regular untreated steel, the long-term benefits significantly outweigh this initial investment. Given its enhanced lifespan due to its resistance to corrosion, maintenance costs are significantly reduced. Over time, this results in substantial savings making galvanised steel an economically wise choice.
What’s more? Galvanised steel also offers great ease in terms of handling and installation. It requires no special handling or treatment prior to installation and can be cut, welded, and formed using standard methods. This makes it a preferred choice for builders and manufacturers alike.
In conclusion, why galvanised steel? Because when you choose galvanised steel, you choose durability, reliability, cost-effectiveness, and ease of use. Stay tuned as we delve deeper into the world of galvanised steel in the upcoming sections of our blog post.
Process of Galvanising Steel
The process of galvanising steel is an intriguing one that combines chemistry with industrial manufacturing. At the base level, galvanisation involves coating steel with a layer of zinc. Why galvanised steel? The answer lies in the protective properties of zinc, which safeguards the steel from harmful elements, hence significantly extending its lifespan.
Galvanising steel commences with thorough cleaning of the steel surface. This stage involves three phases starting with degreasing to rid the surface of any dirt or oil, followed by pickling in a solution of hydrochloric acid to dissolve any existing rust or mill scale. The final cleaning phase is fluxing, where the steel is submerged in a flux solution (usually made of zinc ammonium chloride) to cleanse it further and promote adhesion of the zinc.
Once cleaned, the steel moves into the heart of this process – hot-dip galvanisation. Herein, the steel is submerged in a bath of molten zinc at approximately 450°C. This high temperature causes a metallurgical reaction between the iron in the steel and the molten zinc, resulting in bonding that forms multiple layers of zinc-iron alloys on the surface. These alloy layers are even tougher than both the base steel and pure zinc.
A final cooling and inspection stage concludes this process, after which we have galvanised steel. It’s noteworthy that every part of the immersed steel gets coated during galvanisation including inside, outside, awkward corners, and narrow gaps which may be hard-to-reach during other coating processes.
Another galvanising technique is electro-galvanisation – here electric current is used to bond zinc to the steel in a cyanide or sulfate solution. While not providing as thick or durable a coating as hot-dip galvanisation, electro-galvanisation allows for better control over the thickness of the zinc layer and is thus more suitable for products requiring a thinner coating.
So, why galvanised steel? The outcome of this process is a material that fuses the strength and formability of steel with the durability and protection of zinc. This gives galvanised steel its resistance to factors like rust, scratches, and other types of wear-and-tear, making it an excellent choice in demanding environments.
