Purchase Report

Industry Summary

The 4,830 metal finishing companies in the US provide finishing services for manufacturing and construction customers. Major revenue categories include metal coating and engraving; electroplating, plating, polishing, anodizing, and coloring; and metal heat treating. Companies provide finishing services for customer-supplied metal goods and may sell finished metal goods. Some companies offer finishing services for alternative materials, such as plastics and composites.

Waste and Regulation

The metal finishing industry is highly regulated because processes often involve dangerous chemicals and the generation of hazardous waste.

Captive Finishing

Companies may compete with manufacturers that opt for in-house metal finishing activities instead of outsourcing to a third party (“captive finishing”).


Recent Developments

Jun 21, 2025 - Trade Policies Depress Factory Activity
  • US manufacturing activity contracted further in May, hitting its lowest level since November 2024, reflecting persistent concern over the impact of the Trump administration’s whipsawing trade policy, The Wall Street Journal reports. The Institute for Supply Management’s Manufacturing PMI – an indicator of US economic activity based on a survey of purchasing managers at manufacturing firms nationwide and considered a key indicator of the state of the US economy – fell to 48.5 in May, from 48.7 in April. (A reading below 50 indicates contraction). The last time the index was above 50 (indicating expansion) was in January and February, though that followed 26 consecutive months of contraction. New orders and backlog of orders indexes declined at slower rates than in April, though customers’ inventories and new export orders contracted more strongly. President Trump’s tariff whiplash is making it difficult for manufacturers to plan ahead.
  • Tariffs are raising the cost of raw materials, including steel, zinc, nickel, and other coating and plating materials, used by the metal finishing industry and threaten to disrupt supply chains and the industry’s customers. In June, the Trump administration imposed 50% tariffs on steel and aluminum imports to the US making those metals more expensive and harder to come by. Trump’s “Liberation Day” announcement of reciprocal tariffs on a wide range of imports – including vehicles, auto parts, and appliances – in April (since delayed for 90 days), would have a significant impact on metal finishers' suppliers and customers as well. More broadly, the tariffs threaten to slow economic growth – reducing demand for metal finishing services – and could even drive the US economy into recession. In early April, J.P. Morgan Research raised the probability of a recession occurring in 2025 to 60% — up from 40%.
  • While white and neutral colors continue to reign as the most popular choices for vehicles in North America this year, industry insiders expect consumers to gravitate toward bolder colors in years ahead. “We have been predicting that consumers will be ready now and in the next decade for color… and move away from all gray and beige,” said Misty Yeomans, manager of color styling at PPG. Automakers have already responded with Neoteric Yellow (Hyundai) and Molten Magenta (Ford). According to Kelley Blue Book’s 2025 color forecast vivid blue is increasingly popular because it stands out on the road and works well with a variety of car models. Blue’s growth in popularity is a reflection of shifting customer preferences, especially among younger drivers. Meanwhile, per BASF’s 2024-2025 Automotive Color Trends report, white represents 34% of car purchases, followed by black (22%), silver (14%), gray (10%), blue (9%), and red (8%).
  • Producer prices for metal coating, engraving, and heat treating firms rose 4.3% in May compared to a year ago after rising 5.5% in the previous annual comparison, according to the latest US Bureau of Labor Statistics data. Industry producer prices have been rising steadily since early 2021 as demand for finished metal goods increased as the US economy reopened following the pandemic. Employment by the industry remained flat in April and is stuck below pre-pandemic levels. Meanwhile, average wages at coating, engraving, heat treating, and allied activities rose 3.5% in April to $23.71 per hour, BLS data show.
