Coating, engraving, cold and heat treating and allied activities

This industry comprises establishments primarily engaged in coating, engraving, heat treating and similarly processing metal. These activities often involve heating the metal, and the purpose is often to harden it. In general, the hardening of metal is included. Other activities of this industry include tempering, brazing, plating (including electroplating and re-chroming), polishing, sand-blasting and colouring metal and metal products. Establishments that perform these processes on other materials, such as plastics, in addition to metals, as well as establishments primarily engaged in plating with precious metal for the trade are included. — Statistics Canada, NAICS 2022A

Size and shape

How many businesses there are and how small they are. Fragmentation is the first thing an entrant — or anyone selling software into this industry — needs to know, and it is one of the few things that is actually measured.

Largest four provinces by establishment count. Establishments with employees only — sole operators with no payroll are not in this table, so in trades and personal services the true number of businesses is higher.

Measured, not forecast: the share of US establishments opening in one year that were still active later. It counts good operators and bad ones together, which is exactly why it is the honest answer to “what are the odds”. It is for the whole sector rather than this market, and the ten-year figure comes from an older cohort because no younger one has reached ten years.

No US figure is shown. County Business Patterns is coded to the 2017 US edition of NAICS; this code either does not exist there, names a different industry, or is outside the programme's coverage (most of agriculture, rail, postal and public administration are). A figure is attached only where both the code and the title agree.

Heat Treating & Plating ShopStructure decides
binding constraint: capital intensity

This is the service end of metalworking: a machine shop sends parts out to be hardened, plated, anodised or coated and gets them back in days. The customer base is local and sticky, the work is priced per lot rather than bid against imports, and most of Canada's 584 establishments are small — 64% employ between five and forty-nine people. The cut is what the process costs to own. Bodycote, the largest listed heat treater, earned a 15.7% adjusted operating margin on £727.1M of revenue in 2025 — and spent £77.0M on capital expenditure, 10.6% of revenue, across 136 locations [A]. That is roughly £5M of revenue per plant, each a building full of furnaces, atmospheres and quench systems that burn energy whether or not the racks are full. More telling is what it is doing with its ordinary plants: 31 sites have been declared non-core — described by the company as "older, less efficient and more carbon-intensive" heat treatment serving automotive and general industry — and are being closed, merged or sold, ten of them in France in one transaction [A]. Revenue fell 4%. The general-purpose shop serving local industry is precisely what the scale operator is exiting; the margin sits in aerospace, gas-turbine and specialist processes that require accreditation and years of customer qualification. Plating adds a second weight the heat treater escapes — chemical baths, wastewater permits and the contamination history of any site bought. An entrant can buy a shop, but it buys a furnace-replacement schedule with it.
