The Differences Between Galvanised and Non-Galvanised Steel

When looking for steel pipes, you might be surprised that they come in two different types: galvanised and non-galvanised. Before you make your selection, it's important to understand the differences between these two types of pipe.

This blog will explore the differences between galvanised steel pipes and non-galvanised pipes so that you can make an informed decision about what's right for your facility.

But let’s dive into the definitions of galvanised and non-galvanised pipes.

Galvanised Steel Pipes Vs. Non-Galvanised Steel Pipes

Galvanised steel pipes are the most common type of steel pipes used in construction. They are made by using a hot-dip galvanising process, which is a chemical coating that protects the steel from corrosion. The hot-dip galvanising process uses molten zinc to coat the steel pipe's surface, which protects it from rusting. Other galvanisation techniques include continuous galvanisation, electroplating, mechanical plating, thermal spraying, and diffusion.

Pipes and pipe components manufactured by Jacob UK are protected against corrosion in steel so that they may operate reliably under a wide range of environmental conditions. With our stainless steel modular pipework system, you can choose from various product categories, such as spray-primed, galvanised, and powder-coated pipes.

Non-galvanised steel pipes do not have this protective layer on them, and so they tend to rust faster than galvanised ones. The main reason why non-galvanised steel pipes are not as popular as galvanised ones is that they are more expensive and harder to work with because they require extra care when cut or drilled into.

The Difference Between Galvanised And Non-Galvanised Steel Pipes

Steel pipes are used for many things, from building homes to transporting products in manufacturing plants. They can be made of many different kinds of metals, but galvanised steel is one of the most common.

Galvanised steel has a coating of zinc on its surface that resists corrosion. This helps prevent rusting, which can be a problem because it weakens the metal. Non-galvanized steel doesn't have this coating and may need more frequent maintenance to avoid corrosion.

Both types of metal can be used in construction projects or other applications. However, each has distinct advantages and disadvantages that make them better suited for certain situations than others.

Industry Application

While non-galvanised steel can withstand salt water, it deteriorates rapidly in chlorinated water, making galvanised steel the superior choice. For this reason, galvanised steel is preferable to stainless steel when two components produce friction and fuse. Jacob UK recommends its galvanised pipes be used in the agricultural industry.

Non-galvanised steel, in contrast to galvanised steel, is both stronger and more corrosion-resistant, making it ideal for usage in industries like aerospace, where durability is of the utmost importance. Stainless steel's high strength and resistance to corrosion from seawater make it a popular choice for constructing bridges and other structures, sculptures, train lines, and automobiles that rely on a sturdy foundation.

Cost

The cost of galvanised pipes is lower than that of non-galvanized pipes in the long run. This is because galvanised pipes are more durable than non-galvanised ones and do not corrode easily.

Strength

The strength of galvanised pipes depends on the thickness of the coating. The thicker the coating, the better it will be able to withstand corrosion from chemicals in the water or other substances that may come in contact with it. That is why galvanised steel pipes are stronger than non-galvanised steel pipes.

Corrosion resistance

Because galvanised pipes have a protective coating that prevents rusting, they are much more resistant to corrosion than non-galvanised ones. This makes them ideal for use in areas with high humidity or exposure to saltwater or other corrosive substances like acids or alkalis.

Temperature Resistance

To avoid the production of toxic zinc fumes when heated, galvanised steel is not suitable for use in high-temperature applications. Galvanised metal should not be used with utensils or equipment related to food contact surfaces. This is because the zinc coating, which turns into zinc salt when exposed to acids, corrodes far more quickly when consumed alongside acidic foods and beverages.

When it comes to applications that require food safety or can be subjected to high temperatures, it is always better to choose non-galvanised steel rather than galvanised steel.
