Benefits of hot dip galvanizing in agriculture

agri-4Agricultural steelwork has been protected by hot dip galvanizing for more than one hundred years.

In the past it was mainly small objects such as buckets, watering cans and feeding troughs that were galvanized – and they usually  lasted until they were worn out. Today, most steel products can receive the same level of protection, not just building frames and farm gates but all fencing, penstock equipment and appliances.

Why choose galvanizing for farm structures

  1. Great value for money
  2. Long life
  3.  Toughness
  4.  Protects hollow sections externally and internally
  5.  Hygienic for use around animals

Toughness and abrasion resistance

Hot dip galvanizing produces a tough, durable and permanently bonded coating which is better than many other systems in protecting steel from damage, for instance, from tractors or machinery.

What’s more, any bare steel exposed by scratches or drilled holes is protected by the surrounding zinc.


Complete coverage, inside and out is a unique feature of hot dip galvanized coatings.


The abrasion and corrosion resistance of hot dip galvanized steel provides an easy to clean and hygienic surface.

Particularly with building frames, once the hot dip galvanized steel is erected cladding can begin immediately. This eliminates time consuming on-site painting.


Hot dip galvanizing facilities are widely available so your suppliers should be able to offer hot dip galvanized products. It is recommended that a galvanizer is used which is a member of Galvanizers Association. See what your closest galvanizer is.

Environmental performance

Left alone outside, hot dip galvanizing will protect steel from the weather for many decades. It will protect steel from other substances found on farms such as diesel oil and petrol. However, galvanized steel can be attacked by prolonged exposure to acidic materials such as slurry and manure. If this is likely, a coat of bitumen paint should be applied to the galvanized steelwork.

Short term exposure, as in slurry pumps, is not normally a problem providing that the steelwork is rinsed off after use and allowed to dry. It is also advisable to paint galvanized steelwork with bitumen paint if it is going to be immersed continuously in water.
