What is Galvanizing?
Galvanizing, or galvanization, is a manufacturing process where a coating of zinc is applied to steel or iron to offer protection and prevent rusting. There are several galvanizing processes available, but the most commonly offered and used method is called hot-dip galvanizing.
Galvanized steelis among the most popular steel types because of its extended durability, having the strength and formability of steel plus the corrosion protection of the zinc-iron coating. The zinc protects the base metal by acting as a barrier to corrosive elements, and the sacrificial nature of the coating results in a long-lasting and high-quality steel product.
This versatility makes it applicable to a variety of projects and industries, including agriculture, solar, automotive, construction, and so on. Below, we aim to provide a comprehensive description of how galvanized steel is processed, different galvanization methods, its benefits, and how it is used in these various industries.
The steps in the galvanizing process are as follows:
The first and foremost method for galvanization is hot-dip galvanizing. The process is very similar to what the name suggests! In this method, steel or iron is dipped in a molten pool of zinc that maintains a temperature of around 860°F (460 °C). This molten bath begins a metallurgical bond between the zinc and the receiving metal. After the metal is pulled from the bath, it reacts to being exposed to the atmosphere, and the pure zinc mixes with oxygen to form zinc oxide. The zinc-oxide further reacts to carbon dioxide and forms zinc carbonate, which makes up the final protective coating on the material. The tell-tale sign of a hot-dipped galvanized material is the presence of a crystalline-like pattern on the surface, sometimes referred to as “spangle.”

Galvanized Iron Pipes Supplier in India, Gi Seamless Pipes
HEUBACH INTERNATIONAL is one of the large suppliers & exporters for high quality Galvanized Iron Pipes. These pipes are widely used for conveying raw water & distribution of treated water in majority of rural water areas, where the requirement of water is less. Mostly medium quality Galvanized Iron are used. The Galvanized Iron are cheaper, lighter in weight and easy to handle & transport & easy to join them. Galvanized Iron sizes vary from range 15mm to 150mm. The Galavanized Iron are generally manufactured conforming to IS-1239. Generally screwed & socketed pipes are used. The Galvanized Iron welded Pipes shall be manufactured from hot rolled steel strip for welded gi pipes conforming to IS 10748 or Cold-rolled low carbon steel sheets and strips conforming to IS 513. The welded galvanized steel are then passed through sizing sections where any dimensional deviation are being corrected. Galvanized Iron are then pressure tested for any leaks. The Galvanized Iron are then cutted into desired lengths by automatic cutting machines. The varnishing and galvanization of pipes are done as per specific requirements. Also Galvanization is a process in which steel or iron is coated with a layer of zinc to protect them from rusting or corrosion.
