Galvanizing in Agricultural and Industrial Buildings

Steel is one of the most commonly used materials in agriculture for fencing and gates to building frames, feeding barriers, penstock and other equipment.
However, steel must be protected or it will rust, and that costs the agricultural industry many millions of pounds each year. Initial investment into galvanizing offers an economic method of steel protection that is tough, durable and safe with animals.

Maintenance free life

Galvanizing provides an easy to clean hygienic surface which can give your equipment an expected maintenance free life of up to 70 years. (This is dependent on the environment it is being used in).

The galvanized coating on fabricated products such as building frames, gates, penstock equipment and appliances lasts longer as it is about five times thicker than the galvanizing on items before fabrication such as sheet & strip used in roofing. Cladding can also be done immediately after galvanized steel is erected, you don’t have to wait for it to dry.

Lead Free
Wedge Group Galvanizing completed a unique conversion to lead-free galvanizing over ten years ago.
The initiative was made particularly timely by the 2018 reclassification of lead contained in REACH (an EU regulation for the Registration, Evaluation and Authorisation of Chemicals).

Acidic Materials
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 is not normally a problem providing the steelwork is rinsed off after use and allowed to dry.

FAQs

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.
