What types of construction firms do we work with?
LCNW supports teams across the construction industry, including:
- Structural steel fabricators who need laser-cut and formed components for beams, braces, gussets, and base plates
- General contractors managing commercial builds that require reliable turnaround on stair systems, railings, embeds, and anchoring hardware
- Pre-engineered metal building (PEMB) manufacturers looking for precision-cut framing parts, purlins, and panel supports
- Project management and purchasing teams sourcing beam tracks, anchors, tie-off points, and safety guardrails for rooftop building access and maintenance
- Construction subcontractors—steel erectors, glaziers, or mechanical trades—who rely on custom fabrication to integrate with on-site systems

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.

In construction, delays cost money, and parts that don’t fit cost even more. Whether it’s a single embed or a full run of framing assemblies, LCNW delivers parts that arrive right, install fast, and hold up over time. Our team works closely with contractors, engineers, and fabricators to keep schedules tight and quality consistent. We offer:
- Material sourcing from vetted U.S. mills and distributors
- Laser cutting and forming for brackets, embeds, and structural plates
- Precision CNC machining for mounting points and anchor systems
- Structural welding and fabrication per AWS and AISC standards
- Labeling, kitting, and delivery tailored to your install sequence
American Fabrication for Construction
Every component is made in the U.S. using proven fabrication workflows. From fast-tracked RFIs to phased deliveries, we’re built to support the pace and complexity of modern construction projects.
- Structural steel suppliers and GC sub-trades
- Architectural metal contractors and facade installers
- Short-run parts for coordination or site fixes
- Production runs for large-scale framing or panel systems
At LCNW, we help construction teams avoid rework, stay on schedule, and meet spec. If you’re tired of shops that ghost you mid-project or ship out-of-tolerance parts—give us a call.
We’ll build what you need. And we’ll get it there on time.

FAQs
Are your structural components fabricated in the U.S.?
Yes — all fabrication is done right here on our campus. If your contract includes domestic material requirements, we’re happy to review them to ensure compliance. Mill Test Reports (MTRs) can be provided upon request.
Can I speak to someone before I submit plans or RFIs?
Absolutely, and we encourage it. Whether you’re working from finalized drawings or need input on value-engineering a detail, our team is available to review early. That upfront coordination often helps prevent costly rework later on.
What do you need from me to quote structural steel?
A set of shop drawings with a material schedule is ideal. The more complete the information — including member sizes, connection details, and any project specs — the faster we can deliver an accurate, competitive quote.
Do you offer connection design or engineering review?
We don’t perform structural engineering or delegated design, but we do flag any drawing issues that may affect fabrication. Our team focuses on building exactly to your supplied shop drawing spec. When details can be simplified for fabrication or sequencing, we’ll call that out early so your project stays on track.
Do you provide field measurements or site verification?
We don’t offer field measuring or on-site verification services. Our focus is on fabricating accurately to the shop drawings you provide. That allows us to prioritize lead times and deliver your products on schedule.
Do you handle galvanizing or other protective finishes?
We do. We regularly fabricate steel for galvanized, coated, and painted installations, including duplex systems and fire-rated finishes. Let us know your coating requirements at the quote stage so we can coordinate with our finishing partners and avoid hold-ups.
Can you fabricate structural assemblies or pre-welded frames?
Yes. We often fabricate complete assemblies—frames, embeds, welded box sections, stair stringers, and more—that are easier to install on-site. Pre-welding saves labor in the field and keeps installs moving faster, especially when crane time is tight.
What kind of jobs do you typically support?
We fabricate for a wide range of projects — commercial, multi-family, institutional, and industrial. Whether it’s a field skid for groundwork or a multi-ton steel package for a new build, we bring the same level of precision and clear communication to every job.
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
What certifications do you carry for structural fabrication?
We’re ISO 9001 certified, which reflects our commitment to consistent quality management across all processes. Our welding procedures and operator qualifications follow AWS standards and align with AISC guidelines — ensuring reliable weld integrity for structural, safety-critical, and code-compliant builds. It’s one of the reasons we’re an approved fabricator for city of Los Angeles.
