AZZ's products act as a shield for steel. The company has two business segments: galvanizing services and energy. To protect steel from environmental corrosion, galvanizing services dip steel products into baths of molten zinc. The process is vital for steel fabricators who serve highway construction, electrical utility, transportation, and water-treatment firms. Through subsidiaries, AZZ makes electrical power distribution systems, industrial lighting, switchgear, motor control centers, bus duct systems, and tubular goods. Industrial, petrochemical, and power generation and transmission companies use the company's products.
