Galvanization can be defined as the process of coating zinc to metals such as iron or steel to prevent the process of rusting. Rusting not only makes the outer appearance of the metal unpleasant, but also reduces the tensile strength of the metal, thereby affecting the overall lifespan of the metal. Galvanization can be done through different processes. However, hot-dip galvanization and electrogalvanization are the common types. Hot-dip galvanization helps deposit a thick layer of zinc coating on the surface of the metal, while electrogalvanization is applied when a thin layer of zinc coating is required.

Hot-dip galvanizing (HDG) is the process of dipping steel bar in a container or kettle containing zinc in molten state. HDG metals offer several advantages such as durability, abrasion resistance, uniform protection, and complete coverage. HDG metals are employed in a wide range of applications in industrial, power, utility, petrochemical, and construction projects due to their unmatched durability. The coating on the surface of the metal is uniform in design, i.e. its thickness is the same across the edges as in flat surfaces. HDG metals maintain their corrosion resistance properties and fulfill the intended design life when exposed to UV rays, snow, concrete, submerged in water, embedded in sand, or any other harsh environment.
Based on furnace type, the market for hot-dip galvanization can be segmented into ceramic and steel kettle. Based on the type of combustion system, the market can be segregated into oil, gas, and electric. In terms of end-user industry, the market for hot-dip galvanization can be divided into building & construction, automotive, electric & electronics, and others.
The market for hot-dip galvanization is anticipated to expand significantly during the forecast period owing to the expansion of end-user industries. Rise in demand for hot-dip galvanization considering its low initial cost; easy availability; and high durability, sustainability, and longevity is the primary factor driving the hot-dip galvanization market. Development in the construction industry is anticipated to offer opportunities to the hot-dip galvanization market, as hot-dip galvanized products are used as bars, rods, and sheets in infrastructure development. Increase in renovation activities coupled with the rise in investment in residential and commercial projects is estimated to boost the construction industry. This, in turn, is projected to propel the hot-dip galvanization market during the forecast period.
