Industrial Plant and Equipment

Maintenance free corrosion protection

Industrial facilities have some of the most aggressive, hostile environments for steel and metals.  Hot-dip galvanized steel is uniquely and ideally suited to withstand the constant exposure and abuse of these industries.  Whether in contact with chemicals, water, oil, or other corrosive materials, hot-dip galvanized steel provides maintenance-free corrosion protection for decades.

In addition to being able to combat corrosion in such a hostile environment, the maintenance-free nature of the zinc coating means galvanized structures are also more economical over the life of the product.

Because of its durability, low life-cycle cost, and maintenance-free nature which eliminates costly plant downtime, hot-dip galvanized steel is the preferred choice of protection in industrial projects.

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.
