The US metal coating, engraving, and heat treating industry includes more than 5,000 companies with combined annual revenue of about $25 billion. Major companies include AZZ, Precoat Metals (a division of Sequa), Pro-Tec, and the coatings division of Valmont Industries. The industry is fragmented: the largest 50 companies generate about 30 percent of revenue.
Demand depends on the level of manufacturing production and construction activity. The profitability of individual companies is linked to manufacturing process efficiencies. Most companies are small and compete by focusing on a specialty customer niche within a local or regional area.
Major services are metal surface finishing treatments that include engraving, galvanizing, and coating; electroplating, plating, anodizing, and coloring; and heat treating.
