Both stainless steel and galvanised steel are durable and strong. These two types of steel are the most common materials used in the construction industry. They are used for Flat Bar, T-Bar, Steel Angles, and more. This is the reason why they are frequently mistaken to be the same. Yet, they differ in terms of composition, weight, and strength, and are used in various applications as well. There are numerous ways on how to determine whether galvanised steel is more effective to use compared to stainless steel.
Differentiating Galvanised Steel from Stainless Steel
Preparation and Composition
Compared to regular iron-made steel, galvanised steel has a zinc coating, which enables it to be resistant to corrosion. Hot-dip galvanisation is considered the most common form of galvanization, which aims to guarantee that steel can hold well and that it will not rust especially even with exposure to different elements. Galvanised steel is usually utilized in various types of fasteners like bolts and nails.
Hot-dip galvanisation guarantees that zinc comes into contact with every portion of the steel. Galvanised steel also provides the necessary protection for both internal and external steel surfaces against all forms of corrosion and rust.
On the other hand, stainless steel is created through the addition of chromium to regular steel in its molten state. Chromium contributes to the strength and high resistance of stainless steel to rust. Stainless steel can tolerate both saltwater and freshwater, and this sets it apart from galvanised steel. It can be used for manufacturing working parts of certain tools such as saw blades.
Nevertheless, despite the fact that stainless steel maintains its anti-corrosive properties more than galvanised steel, it is not recommended for use in sites where there is exposure to chlorine like swimming pools.
Galvanised steel is more affordable compared to stainless steel. Due to its cost-efficiency, it is widely used in sites where there are lesser risks or damages such as the construction of fittings and pipes in homes. It is most recommended for small-budget projects as well. It also requires less maintenance compared to stainless steel. It is also long-lasting compared to other forms of steel having different protective coatings.
Strength and Resistance
Galvanised steel can be easily maintained since it is not prone to cracking or shrinking. Zinc has the capacity to coat steel in an impervious manner. Nevertheless, scratching steel will expose its inner layers, which will make it more resistant to corrosion.
Though galvanised steel does not give protection against any form of rust compared to stainless steel, it also contains self-healing properties. Even though zinc is subject to corrosion, it will protect the steel since corrosive products may be deposited on the steel itself.
Generally, galvanised steel is a better choice over stainless steel due to the above-mentioned properties. If you will be using fasteners, screws, hinges, and other fitting accessories, galvanised steel products are considered a better choice since they are less expensive. It can be easily maintained since it is not easily subjected to corrosion, cracking or shrinkage, making it the ideal material for construction.
