Fabrication Assembly
What Is Fabrication Assembly?
Fabrication assembly is the step where individual metal components, whether they’re cut, formed, or welded separately, come together into a single finished product. It covers everything from bolting and mechanical fastening to sub-assembly integration and final welding. For us, it’s the natural extension of the cutting, forming, and welding we already do under one roof: since our team builds the parts, we’re positioned to put them together correctly the first time, without shipping components out to a second shop for assembly.
What Does Fabrication Assembly Include?
Our fabrication assembly services cover the full path from raw material to finished product. Depending on your project, that includes:
- Custom metal fabrication and sub-assembly of individual components
- Sanitary and food-grade welding for equipment entering food or beverage production
- Shearing and CNC forming of the parts that go into the final build
- High-definition plasma cutting and profile burning
- Cut-to-length processing for structural and framing components
- Mobile welding on larger assemblies that are more practical to finish onsite
- Installation support once the finished assembly reaches your site
Because we handle cutting, forming, and welding ourselves, we can move a project from sub-assembly to final assembly without waiting on an outside vendor to catch up.
Metal Materials We Assemble With
The right material for your assembly depends on the load it needs to carry, the environment it will sit in, and your budget. We regularly assemble finished products in:
- Steel, for structural strength and cost-effective builds
- Stainless steel, for food-grade, sanitary, and corrosion-resistant applications
- Aluminum, where weight matters as much as strength
We’ll help you weigh those factors against your project’s real-world use before we start cutting, so the material you choose is the one that holds up.
Our Fabrication Assembly Process
We treat assembly as a sequence, not a single step at the end of the job. Our process runs through:
- Planning and design review: we work from your drawings or sketches to confirm dimensions, tolerances, and how the finished piece needs to fit into its surroundings.
- Material selection: we match steel, stainless steel, or aluminum to the job based on strength, corrosion resistance, and cost.
- Cutting, forming, and welding: our shearing, CNC forming, plasma cutting, and MIG, TIG, stick, and sanitary welding processes turn raw material into finished components.
- Sub-assembly: related components are joined into intermediate units before final integration, which keeps quality control tight at every stage rather than only at the end.
- Final assembly and finishing: we bring the sub-assemblies together into the completed product and finish it to spec, ready for delivery or onsite installation.
Assembly timelines depend on part count, material availability, and how much sub-assembly work the project requires before final integration. A straightforward assembly built from parts we’re already cutting in-house can move through our shop in a matter of days. Larger or multi-stage assemblies, ones with several sub-assemblies feeding into a final build, need more coordination between our cutting, forming, and welding stations and typically run longer. We’ll give you a realistic timeline once we’ve reviewed your drawings, so you’re scheduling around a real date instead of a guess.
Fabrication Assembly From LWS Manufacturing & Welding
We’ve been serving the Lower Mainland since 1983, and our team brings over 100 years of combined experience to every assembly that leaves our shop. Whether your project needs a simple sub-assembly or a fully integrated finished product, we handle the cutting, forming, welding, and assembly under one roof, so you’re coordinating with one shop instead of several. Contact us today to discuss your fabrication assembly project and get a straight answer on scope and timeline.
Frequently Asked Questions
What's the difference between sub-assembly and final assembly?
Sub-assembly joins related components into an intermediate unit, while final assembly brings those sub-assemblies together into the completed product. We handle both, which keeps quality checks happening at each stage instead of only at the end.
Can you assemble a project from parts you didn't fabricate yourself?
Our assembly work is built around components we cut, form, and weld in-house. Talk to our team about your specific parts and drawings so we can tell you what’s realistic.
Do you handle food-grade or sanitary assemblies?
Yes. Our sanitary welding capability supports assemblies headed into food and beverage production, including stainless steel fittings, tubing, and equipment that needs a clean, corrosion-resistant finish.
What information do you need before quoting an assembly project?
Drawings or sketches, the materials involved, and any site or installation requirements. That’s enough for us to scope the sub-assembly stages, pick materials, and give you a realistic timeline.
Do you assemble onsite or only in your shop?
Both. Most assembly work happens in our shop, but our mobile welding capability lets us complete larger assemblies onsite when that’s more practical than transporting a finished build.
Is CSA-certified welding required for my assembly?
It depends on the application, but our welders work to CSA W47.1 and W59 standards on every assembly regardless, so you’re covered if your project does require it.
How do I get a timeline for my project?
Contact us with your drawings or project details. Once we’ve reviewed the scope, part count, and materials, we’ll give you a realistic timeline instead of a general estimate.
