Entry signal — what decides who wins here
Structure decidesThe binding constraint is not executional. Being better than the incumbent does not, by itself, get you in — this one is cleared with capital, an asset, or a permission.
Come with the asset, or buy the business that owns it. Plant, fleet, land or quota decide this market before any operating skill does. Operators here are bought, not started.
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.
This is not a probability of success, and it is not a verdict on you. No survival probability is published per market, and inventing one would be worse than saying so. What the bar reads is how much of the outcome sits inside an operator's control: green means the hurdles are ones a better operator clears, red means the binding constraint is capital, an asset or a permission rather than execution. Someone arriving with an advantage this screen did not assume can win a market shown in red.

The 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.
Parts are heavy, the process is a step inside someone else's lead time, and trucks run daily loops, so a treater or plater serves the metalworking cluster around it. That is why Ontario holds 250 of 584 establishments. Aerospace and other accredited specialist work travels further, but it is not the work a new or small shop wins.
Who you would be competing with
The operators already at scale here, and whoever is buying these businesses. In most of these industries the competition an entrant meets is local, so this is who sets the terms rather than a list of everyone in the trade.
Financials & market size — sourced
Figures that came from a filing, a results release or reputable reporting, each carrying its evidence tier.
Market size, derived
Built from the competitor set upward rather than quoted from a forecast. Published TAMs in these categories are frequently reverse-engineered from each other, so any published figure is checked against the vendor arithmetic rather than trusted on its own.
Disclosed revenue from 3 of 6 named vendors. The market is at least this large.
No vendor has both a disclosed revenue and a published share.
Only a revenue floor is known — the true market is larger by whatever the undisclosed vendors earn.

Evidence
Evidence. The business count is Statistics Canada (December 2023); no US figure joined for this code. All Bodycote figures were read from its own 2025 full-year results release (March 2026), downloaded and parsed [A]; the capex percentage and revenue per location are arithmetic on reported numbers. What they establish: heat treating at scale reinvests about a tenth of revenue each year, and the largest operator is withdrawing from general industrial heat treatment. What they do not establish: anything about plating, anodising, powder coating or sand-blasting, which share this code and have different economics — powder coating in particular is far lighter in capital. The remarks on plating permits and site contamination are analyst judgment with no figure behind them. Bodycote is a global company; no Canadian shop's accounts were found. The cut factor is analyst judgment. Added for the competitive field: Aalberts' industry-segment revenue, EBITA, margin and capital expenditure, and the Paulo Products purchase (€169.0M cash outflow, six plants, about US$105M of revenue, 522 employees), were read from Aalberts' own full-year 2025 press release of 26 February 2026, downloaded and parsed [A]; the capex-to-segment-revenue ratio is arithmetic on two figures in that release. Aalberts' industry segment is wider than heat treatment — it also holds specialised machining — so it sizes the consolidator, not the niche. Nitrex and Curtiss-Wright's Metal Improvement Company are named without figures because neither publishes them at this level.
