With competitive price and timely delivery, Heyou sincerely hope to be your supplier and partner.
In order to choose the right product for your project you need to take into account not only the human or animal elements that you wish to control such as preventing stock, human intrusion or health and safety issues but also the climatic elements that will affect the longevity of your fence.
And the principle concern here is corrosion. This is the formidable, silent enemy of all things metallic because, as Neil Young tells us, &#;rust never sleeps&#;.
What standards govern the galvanized steel process?
Australia and New Zealand are well armed with standards that outline the appropriate use of steel and the ideal galvanizing process for those critical fencing areas. It is important that you build your fence in accordance with these guidelines and so you either need to spend some time understanding the requirements or seek expert advice.
If you fail to do this you may end up with fencing that is subject to premature failure leaving you liable to expensive replacement costs, security and animal control issues, and even prosecution under health and safety legislation.
An understanding of the AS & AS/NZS standards, in particular the AS/NZS .2 Guide to the protection of structural steel against atmospheric corrosion by the use of protective coatings &#; Part 2: Hot dip galvanizing, AS/NZS , and AS is pivotal here. These three standards cover the design, durability, and manufacturing processes involved in the manufacture of galvanized steel mesh products.
Fortunately, recent revisions have made the standards considerably easier to follow so let&#;s look at some of the key elements that will help you choose the right product for the maximum durability of your fence.
How does galvanizing prevent corrosion?
Galvanizing protects the underlying steel in three ways:
- By providing a physical barrier of zinc and zinc carbonate preventing corrosive substances from reacting with the underlying steel.
- The zinc, thanks to its greater reactivity, protects the underlying metal by corroding before iron.
- The zinc functions as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the zinc cathodic reaction.
In normal conditions galvanising can provide corrosion protection for the steel core for up to 50 years, or more in arid areas. However, in rural, industrial, and marine environments pollutants including herbicides, sulphur compounds, and high salt content can rapidly increase the corrosion rate of zinc and reduce the life of the fence.
It&#;s important to remember that corrosion rates are also affected by a number of other factors such as rainfall, humidity, temperature, and the thickness of the zinc coating. For example, whereas heavy rainfall can increase corrosion rates in dry conditions, it can however significantly reduce corrosion rates in a highly corrosive marine or industrial environments.
Australian corrosion zones
Rust never sleeps but it is definitely more active under certain conditions and corrosion friendly conditions can significantly reduce the life of your fence.
The standard AS helpfully divides Australia into six corrosion zones: C1 very low (such as dry indoors) ranking as the least corrosive to CX (severe surf shoreline) being the most corrosive.
How long will my fence last?
Remember that a number of factors will influence the lifespan of your fence including humidity, temperature, and exposure to salts. Prevailing winds can push corrosive salt-laden air further inland as well.
However, there is a clear linear relationship between the thickness of the zinc coating and the duration before the wire mesh will require maintenance. Below are some examples (based on information from the Galvanizers Association of Australia) to express this in easy to understand terms:
- Steel with a galvanized coating thickness of 85 µm in a C2 environment will last between 30 to 50 years before maintenance is required
- Steel with a galvanized coating thickness of 85 µm in a C4 environment &#; 20 to 40 years before maintenance is required
- Steel with a galvanized coating thickness of 85 µm in a C5 environment &#; 10 to 25 years before maintenance is required
- Steel with a galvanized coating thickness of 85 µm in a C6 environment &#; 5 to 10 years before maintenance is required
Protective fencing can produce a wide range of galvanized steel mesh with varying wire types and surface coatings to suit every application.
Getting the best out of your fence
Galvanized steel mesh panels are some of the best fencing products available for Australia&#;s tough conditions; galvanizing has been protecting steel for 140 years with outstanding success. With the right product for the conditions, correctly installed and maintained, your galvanized steel fence will last for many decades.
Periodic maintenance inspections will quickly expose areas of damage that may need attention. This is particularly true where galvanized mesh panels are subject to harsh treatment or conditions.
Regular rainfall can help reduce the effects of high salt deposition or the presence of pollutants or aggressive chemicals but a regular cleaning programme may be appropriate in certain situations to prolong the life of galvanized steel sheets.

Stainless steel wire mesh is a top-rated product used across several industries. Due to its strength and durability, you can use it in several ways, but remember, it can also be fragile. Any corrosion can significantly impact the quality and appearance of the mesh, and it is critical to know how much you should worry about this. Today&#;s blog gives you an insight into how rusting can effect the appearance and performance of woven wire mesh and what we can do to prevent rusting in it.
For more information, please visit Strong Steel Mesh.
Stainless steel tends to rust when it is exposed to moisture and oxygen. As soon as your woven mesh panels are exposed to excessive moisture, they will start to erode. Remember, the corrosion is irreversible, and once your mesh rusts, it will be completely unusable. In many cases, corrosion occurs when the metal comes in direct contact with salt water. Since salt water does not mix well with acidic acids, it has no ionic charge.
Corrosion usually starts at the contact point and spreads throughout the mesh.
How to Prevent Stainless Steel from Rusting
Stainless steel rusts easily if not taken care of. Rusting can pose a significant safety hazard because the steel tends to become thin and brittle after rust. It can easily break, creating sharp corners and edges that could cause serious injuries. If you wish to prevent your woven steel mesh from rusting, follow these tips:
Use vinegar to clean your
woven mesh panels, and then rinse them with water to remove any residue. It is one of the most popular ways used to prevent stainless steel from rusting.
Try to wash your stainless steel using water and soap at least once a week. It should help you eliminate any oil or dirt on the surface. However, it is best if you don&#;t use harsh chemicals since they may damage your metal&#;s surface.
You must store your woven steel mesh where there is little or no moisture or sunlight. This should help prevent any rust from getting onto your metal sheets. Stainless steel
woven mesh panels are popular products used across industries because of their ability to resist rust. However, if you are in a particularly humid area, your mesh can develop rust, even if it is stainless steel.
Another popular method to help avoid rust is applying a thin layer of oil or wax. You should also put a small amount of lemon juice onto your stainless steel before you store it away.
If you want your stainless steel to look great and stay safe from rusting, you need to maintain it regularly. The most effective way of doing this is by using an acidic liquid to help you eliminate any oxidation that might be taking place on your mesh.
