Electrical steel, a key material in the manufacturing of electrical components like transformers, motors, and generators, demands specialized coatings to enhance performance, prevent corrosion, and ensure operational efficiency. The electrical steel coating market has emerged as an essential segment within the broader electrical and electronics industry, driven by rising demand for energy-efficient devices, renewable power systems, and electric vehicles (EVs). These coatings not only improve the steel’s insulation properties but also reduce core losses, making them vital in high-performance electrical systems.

The electrical steel coating market has witnessed significant growth over the past decade, owing to rapid industrialization and electrification across developing economies. Coated electrical steel is primarily used in power generation, distribution, and end-user applications in the automotive and consumer electronics industries. Coatings are typically applied to two main types of electrical steel: grain-oriented electrical steel (GOES) and non-grain-oriented electrical steel (NGOES), with different coating needs based on their specific end-uses.

With rising energy demands and increased deployment of smart grid infrastructure, the need for efficient energy transmission and distribution equipment is boosting the consumption of coated electrical steel. The market is also benefiting from stringent government regulations targeting energy efficiency and carbon emissions.

Electrical Steel Coating Market CAGR (growth rate) is expected to be around 2.19% during the forecast period (2025 - 2034).  

Market Drivers

• Rise in Electric Vehicle (EV) Production
  The growing EV market requires high-performance electric motors made with non-grain-oriented electrical steel. Coatings are critical to reduce eddy current losses and improve thermal conductivity. As EV adoption accelerates globally, so does the demand for coated electrical steel.
• Growth of Renewable Energy Infrastructure
  Wind turbines and solar inverters utilize electrical steel for their core components. Coatings enhance insulation, reduce energy loss, and improve component lifespan. The global shift toward sustainable energy is a major growth catalyst for this market.
• Energy Efficiency Standards
  Governments and international regulatory bodies have mandated energy efficiency standards, especially in home appliances and industrial motors. Coated electrical steel helps manufacturers meet these standards by reducing energy consumption and improving operational efficiency.
• Transformer Demand
  With urban expansion and the electrification of rural areas, the demand for transformers is surging. Grain-oriented electrical steel coated with insulation materials is essential in transformer cores to minimize losses and maximize performance.
