Galvanisation, security fencing and you

09th August 2018

Wire mesh perimeter fencing is much more secure than other types of fencing. Its flexible structure allows it to absorb shocks, which means that it is hard for would-be intruders to force their way through. It is also difficult for prospective intruders to cut their way through this type of fencing because many different cross-sections of steel wire have to be severed to create a gap large enough for a person to fit through. However, not all wire mesh fencing panels are equally secure. The most secure fencing options go through a process that greatly increases their efficacy. This process is called hot-dip galvanisation, and we’ll discuss why it’s important for your security fencing in today’s blog entry.

1. What is galvanisation?

Mesh fences are usually made from a latticework of steel wires. Steel is a strong and highly stable material. However, it is susceptible to certain types of damage and may eventually break or fail if it isn’t properly treated. Hot-dip galvanisation involves dipping steel structures in molten zinc, which is kept at a temperature of roughly 460 degrees centigrade. The zinc adheres to the surface of the steel structure and reacts with the steel, creating a resilient layer of mixed zinc and steel molecules. The process is repeated several times to create several protective shells. The outermost shell is pure zinc.

2. What are the advantages of galvanisation?

Steel is much more rust-resistant than iron, but it eventually corrodes if exposed to the elements. Galvanisation can protect from corrosion for between 50 and 75 years. Security fencing panels are exposed to rain, humidity and other corrosive forces every day, so galvanisation can drastically extend their lifespans. What’s more, galvanisation makes steel mesh fences tougher and more resistant to direct physical damage. This is because the zinc flows into and fills the hollow spaces in the steel structure, eliminating points of structural weakness.

3. Is galvanisation the most cost-efficient option?

Galvanisation is clearly essential for creating sturdy, long-term fencing solutions. But is it the most cost-efficient option? It is possible to make fences from corrosion-resistant stainless steel. The material has comparable strength and longevity to galvanised steel but manufacturing it is dramatically more expensive. As a result, galvanising is the most cost-effective option available.

Here at Zaun, we pride ourselves on the quality of our security fencing solutions. We are happy to provide galvanisation for all our clients to ensure that their security fences are long-lasting and physically durable. So please don’t settle for a security fence that hasn’t been adequately fortified and protected from the elements: choose one of our thoroughly galvanised options instead.
