Preparation and coating for non-wear mining components and mineral-processing support fabrications.
Mining OEMs need a practical boundary between corrosion protection and wear protection. PPC reviews conveyor guards, electrical housings and non-wear support frames for surface preparation and powder coating. The specification should identify dust, moisture, washdown and chemical exposure, along with the surfaces that encounter direct ore impact.
Identify sliding ore contact, impact zones and replaceable liners on the drawing. For eligible support components, define incoming mill scale or corrosion, preparation requirements and coating performance. Agree edge coverage and inspection on welds and recesses rather than relying only on flat sample panels.
For outdoor guards or cabinets, review corrosion protection and weatherability together. Indoor support frames may instead be governed by washdown, cleaners and abrasion during maintenance. Use the approved coating product’s evidence for the particular duty, with preparation that addresses the received scale, rust or previous finish.
Agree where to measure film build on welds, edges and recessed areas and what evidence is needed for cure or adhesion. Identify bolt and electrical interfaces that must remain usable. Replacement releases should carry equipment and piece identifiers so the mine can reconcile received parts with the maintenance package.
Crusher wear faces, chute interiors and continuous ore-contact surfaces need dedicated engineering protection. Coating a removable guard does not establish suitability for every process or underground condition at the site.
Application intelligence
Critical-mineral projects and established mines use conveyor guarding, ventilation enclosures, equipment skids, walkways and utility cabinets. Outdoor winter operations add moisture and salt, while ore dust and material impact create an entirely different mechanical hazard.
Assess impact zones, abrasive slurry, chemical processing, humidity and thermal duty individually. Powder coating can protect eligible ancillary metalwork, but chutes and high-velocity ore contact surfaces may require elastomeric liners, hardfacing or other systems. Specify blast cleanliness and corrosion testing for the actual exposure.
PPC can evaluate guards, enclosures, machine support frames and other non-wear structures with heavy-part handling and integrated preparation. Send equipment tags, shutdown dates, site freight restrictions and required surface condition with each RFQ.

These are project-planning considerations, not a representation that every coating chemistry, certification or third-party approval is available for every part. PPC confirms technical feasibility, required testing and the approved process against the project specification.
How PPC supports your project
Prepare and finish guards, processing-equipment frames, walkways' ancillary fittings and removable plant hardware.
Coordinate fabrications and repair components against maintenance outages and remote-site logistics.
Evaluate grit abrasion, humidity, chemical contact and corrosion risk before specifying coating thickness and chemistry.
Share drawings, quantities, finish requirements, budget priorities and delivery dates. Our team can help identify the most practical path forward.
Natural Resources Canada's project showcase documents projects across extraction and processing. For a fabricator, the actionable task is to identify non-wear equipment packages and their specifications rather than assume a mine-wide coating opportunity. No project relationship is implied.

Non-wear guards, enclosure panels, brackets and suitable support frames are useful candidates for review. Separate them from ore-contact liners and continuously immersed or highly chemically exposed equipment.
