Capabilities
Parts, Weldments, and More
Since 1992, LCNW has been committed to leading in precision parts manufacturing. We do this by integrating advanced technology — from automated material handling to high-speed cutting systems — to streamline production and elevate quality.
Laser Cutting: Our high-power lasers can cut steel up to 1.75″ thick, and aluminum or stainless up to 1.5″, on sheets as large as 96″ x 240″. With automated handling, we maintain tight tolerances and handle high volumes with ease.
Bending: Our press brakes form light to heavy gauge material with precision and consistency. Backed by a deep tooling library and material expertise, we deliver clean, accurate results — getting parts right the first time, with no rework needed.
CNC Milling: CNC milling at LCNW delivers tight-tolerance, high-complexity parts with repeatable accuracy. We support both prototyping and large-scale production across a range of materials — always with efficiency, flexibility, and precision.
Welding: From laser welding to MIG and TIG, our team delivers precise, clean welds on steel, stainless, aluminum, and more. Our four robotic welders — including a 62-foot, three-cell system – provide quality throughput on high-volume and complex parts.
Finishing: From in-house finishing services such as deburring, edge breaking, and linear polishing to managing outsourced surface treatments and coatings, LCNW provides a true one-stop shop through our network of trusted finishing partners.
Assembly: We offer full assembly support — from mechanical fastening and labeling to complex subassemblies and kits boxed for distribution. Our team ensures your product is ready to use, saving time, reducing labor, and simplifying your workflow.

AssemblyBuilt 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.

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.
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.
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.
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
