Durable finishes for ships and shipyards.
Our marine powder coating services are tailored for ships and shipyards, engineered to withstand saltwater exposure, UV radiation, and other environmental challenges while meeting stringent naval standards.
Professional Powder Coating Ltd. (PPC) coats non-immersed marine and shipyard metalwork: deck hardware, railings, enclosures, outfitting steel, dock and port equipment, and aluminum boat and trailer components. Parts are blasted or pretreated, then coated with systems evaluated for ISO 12944 C5 or CX exposure, with salt spray, cyclic and UV testing available in-house. Continuously immersed hulls and antifouling are outside the scope of powder coating.
We apply coatings that boost performance and provide exceptional protection against corrosion, abrasion, and chemical exposure.
From surface preparation to final coating, we deliver comprehensive solutions that enhance the durability and appearance of marine vessels.
Shipbuilding and ports in 2026
Canada has committed to decades of naval and coast-guard shipbuilding, and Great Lakes and coastal ports are investing in their infrastructure. Every vessel and terminal needs hundreds of coated fabrications that are not part of the hull.
Irving Shipbuilding in Halifax is building the River-class destroyers. Seaspan in Vancouver is building joint support ships and a polar icebreaker, and Davie in Lévis joined the strategy in 2023 to build polar icebreakers.

Service environments
Marine is not one environment. A vessel or terminal moves through several exposure zones in a few metres, and each needs a different level of protection.
| Setting | Typical parts | Coating exposure |
|---|---|---|
| Splash and spray zoneRailings, deck fittings and hull-side brackets above the waterline.Exposure: Wet–dry cycling in salt water, the most aggressive atmospheric zone (ISO 12944 CX) | Railings, deck fittings and hull-side brackets above the waterline. | Wet–dry cycling in salt water, the most aggressive atmospheric zone (ISO 12944 CX) |

Standards & specifications
Commercial, naval and port owners each write their own requirements. These are the common building blocks.
Corrosivity categories C5 and CX, plus the performance and test regime for offshore and related structures.
Why it matters: Defines the exposure category and the cyclic ageing test used to qualify a coating system.
Source: ISO: International Organization for Standardization (opens in a new tab)U.S. Navy performance specification for powder coatings.
Why it matters: Referenced for naval and some defence-marine hardware. The powder must come from a qualified source.
Source: ASSIST QuickSearch (U.S. military specifications) (opens in a new tab)Neutral salt-spray (fog) exposure.
Why it matters: A widely used comparative screen for pretreatment and coating quality.
Source: ASTM International standards (opens in a new tab)Cyclic salt fog and UV exposure of painted metal.
Why it matters: Alternates wet and UV stress, so it resembles real marine weathering more closely than constant salt fog.

Hulls and immersed structures use specialist marine paint systems. Almost everything bolted to them, and the terminals that serve them, is fabricated steel or aluminum that Professional Powder Coating Ltd. (PPC) can prepare and coat.
Blasting, a zinc-rich or epoxy primer, and a UV-stable topcoat for splash-zone exposure.
Blasting services →Weatherable polyester or fluoropolymer, with bonding and grounding points masked.
Fluoropolymer powder →Durable, cleanable finishes that hold up to humidity and repeated maintenance.
Automated coating →Heavy-duty multi-coat systems tested for chloride exposure and abrasion.
Custom protective coatings →Aluminum-specific pretreatment followed by a marine-grade topcoat, to prevent filiform corrosion.
Surface preparation →Tough, impact-resistant finishes that survive a busy yard and are easy to touch up.
Heavy equipment →Serving U.S. customers
Professional Powder Coating Ltd. (PPC) is in Toronto, near major crossings into New York and Michigan. U.S. marine manufacturers, fabricators and contractors can send parts for coating and receive them finished, as long as the trade and compliance details are settled first.
Professional Powder Coating Ltd. (PPC) packages finished parts to protect them in transit and coordinates shipping to U.S. sites, with commercial documentation prepared for customs clearance. Ship-to address, delivery window and receiving constraints are confirmed at quote stage.
Provide the destination, part dimensions and weight, receiving constraints and required delivery date so handling, packaging and freight can be planned for the project.
Powder coating is not used on continuously immersed hull surfaces, ballast tanks or anywhere antifouling is required. Those areas use specialist liquid marine systems. Mixed-metal assemblies, such as stainless fasteners in aluminum, also need galvanic isolation designed in, because a coating alone will not stop it. Professional Powder Coating Ltd. (PPC) reviews immersion status and metal pairing before quoting.
Supplier readiness

Final values are project-specific. These are the inputs Professional Powder Coating Ltd. (PPC) confirms before approving a production process.
| Technical input | What Professional Powder Coating Ltd. (PPC) confirms |
|---|---|
| Substrate & condition | Material, fabrication method, contamination, corrosion and existing finish. |
| Preparation | Cleaning, stripping, blasting or chemical pretreatment required by the specification. |
| Coating system | Powder chemistry, colour, gloss, texture, film build and cure window. |

| Production & logistics | Quantity, line fit, racking, handling, packaging, freight and delivery cadence. |
From specification to shipment
Confirm the drawing, substrate, part condition, quantity, end use and governing performance requirements.
Select cleaning, stripping, blasting or chemical pretreatment appropriate to the substrate and specification.
Control coating application, film build, grounding and cure around the approved process window.
Verify agreed acceptance criteria, document results when required, then package the finish for shipment.
Complete project information helps Professional Powder Coating Ltd. (PPC) assess feasibility, select the correct process and return a useful quotation.
Professional Powder Coating Ltd. (PPC) explains that yes, on non-immersed metalwork such as railings, deck hardware, enclosures, towers and outfitting steel. Continuously immersed hull surfaces and antifouling areas use specialist liquid systems.
Professional Powder Coating Ltd. (PPC) explains that splash-zone parts need thorough blasting, a corrosion-inhibiting primer and a UV-stable topcoat at controlled film build. The system is chosen against ISO 12944 C5 or CX exposure and can be screened with salt spray or cyclic testing.
Send the specification. The powder must come from a qualified source, and Professional Powder Coating Ltd. (PPC) will confirm availability and the inspection requirements before quoting.
Professional Powder Coating Ltd. (PPC) explains that aluminum needs a pretreatment designed for it, not the process used for steel. Proper cleaning and conversion coating are the main defence against filiform corrosion under the film.
