Overview
Induscoat fabricates custom industrial parts — stainless, machined, welded, wear and corrosion-resistant parts — for plants in Quebec and Ontario. When drawings are missing, we rebuild the part by reverse engineering. Material and protection are selected for the actual service, and every part ships with its material certificates and inspection records.
Induscoat sources and supplies custom-fabricated industrial metalwork for maintenance shutdowns, plant expansions and asset upgrades across mining, energy and process industries. Our scope covers structural steel assemblies (platforms, walkways, handrails, gratings), stainless and carbon steel process piping, and precision-machined components. We perform reverse design from worn parts when original drawings are unavailable — capturing geometry by measurement and producing replacement components to exact dimensional requirements. All supplied welded fabrications are qualified per ASME Section IX (WPS/PQR) and delivered with NDT inspection reports and material certificates.
What custom parts fabrication covers
We fabricate the part missing from the equipment you maintain, from a drawing, a worn part or a specification. The scope stays within maintenance and modification of process equipment:
- machined replacement parts: shafts, bushings, rings, end covers, flanges, pump and valve parts;
- stainless and corrosion-resistant alloy parts: spools, nozzles, vessel internals, spray nozzles;
- welded assemblies: supports, frames, chutes, hoppers, platforms and handrails;
- corrosion-resistant parts in coated or lined carbon steel, when a solid alloy is not justified;
- wear parts, alongside our range of foundry castings and wear parts.
A part that retains pressure (flange, spool, nozzle, valve body) or that is used for lifting (spreader beam, lifting lug) is not made from a field survey alone. Its design goes through an engineer who calculates and seals it under the applicable codes — ASME B31.3 (process piping), CSA B51 (boiler, pressure vessel and pressure piping code), ASME BTH-1 (design of below-the-hook lifting devices) — and, for pressure equipment, through the design registration required by the provincial authority. We build those parts to an approved drawing, never as a direct copy.
Selecting the material and the protection
The original material is not a reference: if the part failed, the material and environment pairing is often the cause. We start from the service conditions — fluid, chlorides, pH, temperature, suspended solids, contact with other metals — and follow a simple logic:
- corrosion only, low chlorides: austenitic stainless, passivated after fabrication;
- chlorides, risk of pitting or crevice corrosion: a grade with a higher PREN (duplex, super-austenitic) or a nickel alloy;
- abrasion dominant: high-chrome iron, abrasion-resistant steel, hardfacing or ceramic;
- abrasion and corrosion combined: steel coated with a ceramic-filled composite, or a wear alloy compatible with the medium;
- bulky part in moderately corrosive service: coated or lined carbon steel.
Grades, PREN screening and passivation are covered in detail in our guide to custom corrosion-resistant parts fabrication. A machined part for a classified area has its own material and documentation rules: see machined components for ATEX and hazardous locations.
When the part is coated, the protection is decided at the design stage: a seal groove or a seating face must allow for the specified film thickness, or the coated part no longer fits. The coating is applied by our protective coatings service, under the same dossier.
How a job runs, from survey to delivery
The steps:
- Assessment: we examine the part, in the shop or on site, with its mating parts (shaft, housing, flange) and the failure history.
- Survey and drawing: without original drawings, a dimensional survey — and 3D scanning for complex geometry — then reconstruction of the original dimensions rather than the worn ones. The method is set out in our guide to reverse engineering replacement parts.
- Technical quotation: material, manufacturing route (machining from solid, welded fabrication, casting, or cast blank plus machining), protection and planned inspections.
- Approval: your team signs off the drawing and quotation before fabrication starts.
- Fabrication: machining, welding to a qualified procedure, heat treatment where specified, passivation of stainless, coating.
- Inspection and hand-over of the dossier with the part.
The rebuilt drawing stays on file: the next order goes ahead without a new survey.
Quality control and documentation
Every part ships with a dossier that lets you check it on receipt and remake it later:
- material certificates (mill test reports) tied to the heat number, grades designated under the applicable ASTM standard — for example ASTM A240 (stainless plate) or ASTM A312 (stainless pipe);
- welding procedure specifications (WPS) supported by their procedure qualification records (PQR) under ASME Section IX, or under CSA W59 (welded steel construction);
- non-destructive testing per the inspection plan: liquid penetrant (PT), magnetic particle (MT), ultrasonic (UT) or radiography (RT);
- dimensional inspection report on the functional dimensions;
- for a coated part: surface preparation, dry film thickness and holiday test records.
If your site requires a CSA W47.1 certified shop, a quality system to ISO 3834 or an NDT qualification level under CAN/CGSB-48.9712, we write it into the quotation and the selected shop must meet it.
Planning around your shutdowns
A custom part is ordered before the shutdown, not during it. In Quebec and Ontario, the planned spring and winter shutdowns set the calendar: the survey is done at a previous opening or on a spare part, fabrication proceeds while the equipment runs, and the part waits on site with its dossier.
What stretches the lead time is rarely the machining: it is sourcing special alloys, the foundry pattern for a first cast part, and drawing approval. For a critical part, have the survey and drawing done now, even if the replacement is only planned for the next shutdown.
If installation has to happen during the shutdown alongside other work, it is planned with our maintenance and rehabilitation service.
When a new part is not the right answer
Fabricating a part is not always the best option. We will tell you so in these cases:
- the part is worn but sound: a rebuild with metal- or ceramic-filled epoxy brings it back to size, often without heavy dismantling — see cold bonding repair;
- the metal is fine and only the protection has failed: a new coating is enough (corrosion protection);
- the original part is available in time and has no design flaw: order it from the original manufacturer;
- it is a standard wear part (liner, jaw, mantle): a casting in the right grade suits better than a one-off fabrication — see crusher wear parts: choosing the alloy;
- it is a complete pressure vessel or a new load-bearing structure: the job goes to a manufacturer holding the required authorizations, on an engineer's design.

Service FAQ
Can you fabricate replacement parts when original drawings are not available?
Yes. Our reverse design process captures the geometry of worn or damaged parts by direct measurement and 3D scanning where required. We produce new technical drawings, specify the correct material grade, and fabricate replacement components to fit — without waiting for OEM approval or original documentation.
Are your welders certified and is documentation provided?
Yes. All welded fabrications are executed by qualified welders under Welding Procedure Specifications (WPS) validated by Procedure Qualification Records (PQR) per ASME Section IX and CSA W47.1/W59. NDT inspection reports, material certificates and as-built drawings are included in the project QA/QC dossier.
Do you supply ready-to-install components or only semi-finished parts?
We supply fully fabricated, inspection-validated components and assemblies, delivered ready for installation. Each delivery includes dimensional control reports, material certificates, welding qualification records (WPS/PQR per ASME Section IX) and NDT inspection reports — everything your team needs to install and document the work with confidence. For complex assemblies requiring field fit-up, we can also provide detailed assembly drawings and dimensional studies.

Custom corrosion-resistant parts fabrication: choosing the material and the protection
A custom part that corrodes early was usually given the wrong material, or the right alloy was spoiled in fabrication. This guide starts from the service conditions, compares stainless, duplex, nickel alloys, titanium, FRP and coated or lined carbon steel, and covers what welding, passivation, crevice-free design and material certificates change.
10 minMachined components for explosive atmospheres: what compliance actually requires
"I need this part in ATEX." The request arrives exactly like that, and on its own it means nothing. A mechanical part is not ATEX-certified the way a motor is: it is designed not to become an ignition source in a given zone. Here is what that imposes on the designer, the material and the documentation — and why "ATEX" is the wrong word in Canada.
