Why Galvanise Steel?

There are many reasons why it is a good idea to galvanise steel but before we touch on a few let’s quickly explain what galvanising is…

Hot dip galvanising is the process of applying a protective zinc coating to steel to prevent rusting. Commonly applied by immersing clean steel into a bath of molten zinc. The zinc and iron react to form several layers which provide a robust coating over the steel.



Good reasons for galvanising steel bars…

It’s a tried and tested technique. People have been galvanising steel for over 200 years due to its effective anti-corrosive properties.

Galvanised steel is widely used in applications where corrosion protection is needed. It has good impact and abrasion resistance and can be relatively maintenance free for 50 years upwards.

The formation of zinc-iron alloy layers provides a tough and abrasion resistant coating meaning less chance of site damage allowing structures to be erected quickly.

The long-term durability provided by galvanising is achieved at a relatively low environmental impact in terms of energy use.

Galvanised bars are ‘self-repairing’. Zinc corrodes over steel and sacrifices itself to protect the steel, known as sacrificial protection.

Our tension rods can be galvanised from M10 – M105 at the following lengths. For further information please take a look at our tension systems brochure here.
