Transport Infrastructure

Widely used in transport infrastructure

Galvanized steel is used widely in transport infrastructure, typical applications include; transmission towers; overhead line fittings; access covers; parapets; gantries and bridges.

Numerous Benefits

There are numerous benefits to hot dip galvanizing, the most significant of which is its ability to dramatically extend the lifetime of steel products in a range of environments; particularly important since an estimated 4% of the world’s GDP is lost each year through corrosion.

Additionally, because hot dip galvanizing takes place after a product has already been fabricated, the steel is coated with a tough and abrasion-resistant zinc coating both externally and internally.

This means the steel product arrives on site ready for immediate use. No further site surface preparation, painting, touch up or inspection is necessary, and installation can begin immediately – thus accelerating the construction time.

Galvanizing: A Sustainable Finish for the Rail Sector

The rail sector continues to be an important sector for us and we are RISQS approved and have been involved in many rail upgrades and electrification programmes throughout the country. 


Hot dip galvanized steel will last very well in most environments. It is not uncommon for galvanized steel to last more than 70 years under certain conditions. Latest corrosion rates can be found at the Galvanizers Association

The three intermetallic layers that form during the galvanizing process are all harder than the substrate steel and have excellent abrasion resistance.

“White Rust”, or wet storage stain, is formed because zinc on newly-galvanized steel is very reactive and quickly forms zinc oxide and zinc hydroxide corrosion products that go on to become the stable zinc carbonate.
When galvanized steel is stacked damp, stored in wet boxes or shrink wrapped with no free-flowing air, the zinc forms excessive layers of zinc hydroxide, otherwise known as wet storage stain.
Most wet storage stain can be easily removed with a nylon brush. To prevent wet storage stain, store galvanized steel indoors and in such a way to allow free-flowing air between each galvanized item.
