Built for Salt, Stress, and Sea Conditions

Marine environments are unforgiving. From corrosion and vibration to constant exposure and load, your parts need to perform without fail. At LCNW, we fabricate metal components built to withstand the realities of shipbuilding, dockside infrastructure, and offshore operations.

Our team works with marine engineers, fabricators, and OEMs to deliver durable, high-spec parts—on time and to spec. Our in-house capabilities include:

  • Material sourcing from vetted U.S. mills and distributors
  • Marine-grade stainless, aluminum, and galvanized steel
  • Laser cutting and forming for hull parts, brackets, panels, and housings
  • CNC machining for tight-tolerance mating components
  • Welding for watertight or load-bearing assemblies
  • Corrosion-resistant coatings and finishes

American Fabrication for Maritime Applications

Every part is made in the U.S. and built for repeatability and ruggedness. Whether you’re fabricating a new vessel or repairing a critical system, we’re equipped to meet your timeline and performance requirements.

At LCNW, we understand the demands of marine fabrication—because we’ve built for it. If you’re dealing with inconsistent suppliers or lead times that don’t work with your dock schedule, let’s talk.

We’ll build what you need. And we’ll get it there on time.

Industries we serve

Same shop, other industries

Since 1992, LCNW has run more than 129,000 jobs for over 1,000 customers, from espresso machines to ship interiors. The same 100,000 sq ft shop in Auburn, WA, the same automated lasers and robotic weld cells, and the same ISO 9001 quality system carry a one-off prototype and a national production rollout alike. Whatever your industry, you get a partner that has already solved problems like yours for someone else.

FAQs

Are your marine fabrication parts & weldments made in the USA?
Yes. Everything we fabricate is done right here in the U.S., with the ability to source materials that meet domestic requirements such as Buy American or DFARS when specified by contract. Mill Test Reports (MTRs) can be provided upon request to support material traceability.
Can I talk to someone before I send in a drawing?
Absolutely. We encourage early conversations. Whether you’re still roughing out a retrofit or need advice on saltwater corrosion resistance, our team is here to help. You can speak directly with someone who understands marine fabrication, and even fill out a form to get a callback on our contact page.
How can marine contractors control costs without compromising durability?
It comes down to repeatability and planning. Consistent builds from a single supplier reduce scrap and rework. Involving a fabricator like LCNW early allows our team to spot cost-saving opportunities. By working with your engineering team to design for manufacturability, LCNW ensures parts are produced as efficiently and cost-effectively as possible.
Is American-made fabrication competitive for marine parts?
Yes. When durability, lead times, and long-term reliability matter, domestic fabrication is often the better investment. Offshore parts might look cheaper on paper, but delays, rework, or rusting fasteners can cost more in the field. With LCNW, you get local accountability and shipyard-tested quality.
What’s the best metal for marine — stainless or aluminum?
It depends. 316 stainless offers excellent corrosion resistance in saltwater and is great for hardware, fasteners, or structural applications. Marine-grade aluminum (like 5052 or 5086) is lightweight and corrosion-resistant, making it ideal for ladders, brackets, or retrofits above the waterline. We work with both and can help you choose based on environment, budget, and strength requirements.
Do laser-cut marine parts need edge finishing?
Yes, especially for parts that will be handled, painted, or exposed to saltwater. We deburr all cut parts as standard practice, and we can apply an edge break to reduce sharpness and improve coating adhesion. It’s a small step that makes a big difference in long-term performance.
What kind of project size do you handle for marine builds?
There’s no strict number, but in general, anything above 50–100 parts per order is considered a small production run. Larger quantities—hundreds to thousands—are what most shops call “full production.” At LCNW, we support both low-and high-volume production, and we can scale up as your product grows, without needing to change suppliers.
What are the best coatings for metal in marine applications?
For aluminum, powder coating is a great option—especially when paired with a chromate conversion layer underneath for better saltwater resistance. Anodizing is also common above the waterline, and epoxy + polyurethane paint systems are used for tougher conditions. For stainless steel, passivation boosts corrosion resistance, especially after welding. Electropolishing is ideal for polished, easy-to-clean finishes. Powder coating is sometimes used for appearance, but stainless often performs well with just proper finishing.
What certifications support marine-quality fabrication?
ISO 9001 is a key certification that signals consistent quality management across processes. All of our welding procedures and operator qualification follow AWS standards, ensuring consistent weld integrity - especially in structural, safety-critical, and code-compliant builds. It’s one of the reasons we’re an approved fabricator for city of Los Angeles.

At LCNW, we follow rigorous internal QA practices and are always seeking ways to improve. We take pride in catching non-conformances before they ever leave the building.
What should be included in a shop drawing?
The more detail you provide upfront, the smoother the process — and the better the outcome. To ensure accuracy and avoid delays, your shop drawing should include:
– Part name or drawing number
– Revision level
– Material type
– Dimensions and tolerances
– Hole placements and bend details
– Secondary processes (e.g., tapping, machining, countersinking)
– Weld symbols and locations
– Hardware callouts
– Bill of Materials (BOM) for assemblies
– Finish requirements (e.g., powder coating, plating)
– Notes or flags for any critical features or inspection points
