What is Custom Metal Fabrication?
Stock fabrication starts from a standard part; custom metal fabrication starts from your specifications. Instead of pulling a pre-made piece off a shelf, we plan and build the part around your exact dimensions, tolerances, and end use. That distinction matters most when a project does not fit anything already in production, whether it is a one-off replacement bracket for a piece of equipment on your line or a new product you are bringing to market for the first time.
Because every specification is different, the fabrication path also changes from job to job. We work with you up front on the materials, processes, and finish requirements so the part performs the way you need it to, not just the way a standard item happens to.
Custom Metal Fabrication Services
Our team draws on 100+ years of combined experience across the following processes to build your custom part:
- Cutting, using CNC plasma cutting for materials up to 1″ thick and CNC router cutting for precision work in plastics and aluminum
- Forming, including rolling, die forming, extrusion, and forging
- Bending, using our brake presses to hit precise angles and repeatable bends
- Rolling, for curved and cylindrical metal shapes
- Assembly, putting fabricated components together into a finished product on site
- Welding, using MIG, TIG, stick, and sanitary welding depending on the material and application
Available Metal Materials
Custom parts start with the right material for the job. We work with:
- Galvanized Steel
- Aluminum
- Stainless Steel
- Copper
- Brass
- Mild Steel
Tell us how the part will be used, what environment it will sit in, and what load or corrosion resistance it needs, and we will help you land on the material that measures up.
The Custom Metal Fabrication Process
Every custom job starts with the design. You can hand us a rough sketch, a hand drawing, or a completed CAD file, and our team will work from whatever you have to confirm the specifications before fabrication begins. Getting this stage right matters: the more complete the drawing or sketch, the fewer questions and delays once the part is in production.
Once the design is confirmed, we move into cutting and forming the material to your specifications, using CNC plasma or CNC router cutting to establish the part’s basic shape and dimensions. From there, we bend, roll, or form the piece using brake presses, rollers, or die forming, depending on what the design calls for. If your part has multiple pieces, our team assembles them on site into the finished product. Where welding is required to join components, we bring in MIG, TIG, stick, or sanitary welding, matched to the material and the application.
Throughout the job, we are consistently checking the part against your original specifications, not just against general shop tolerances. That is what separates a custom fabrication job from a stock one: the part is built and verified against your drawing, start to finish.
Custom Metal Fabrication From LWS Manufacturing & Welding
Whether you are working from a first prototype or scaling up to a full production run, our team at LWS Manufacturing & Welding can help with your custom metal fabrication project. We have been serving the Lower Mainland since 1983, and our shop holds CSA W47.1 and CSA W59 certifications and qualifications.
Frequently Asked Questions
Do you fabricate one-off custom parts or only production runs?
Yes, we fabricate both. A single prototype and a full production run go through the same core processes, including cutting, forming, bending, rolling, assembly, and welding, but the plan around them looks different.
A one-off part is about getting your design right the first time, so we work closely with you on the sketch or drawing before we cut anything. A production run is about repeatability, so once the first piece is approved, we carry that same setup across every part in the order. Whether you need one part or a full run, bring us the specification and we will scope the job around it.
What information do you need before you can quote a custom fabrication job?
Send us your sketch, drawing, or CAD file along with the material, quantity, and any tolerance requirements you already know. The more complete that information is up front, the faster we can put together an accurate quote.
Can you work from a hand-drawn sketch instead of a CAD file?
Yes, we can work from a rough sketch as a starting point. We will confirm the specifications with you before fabrication begins so the finished part matches what you have in mind.
What is the difference between custom fabrication and standard stock fabrication?
Stock fabrication uses parts that already exist in a standard size and shape. Custom fabrication is built around your specific dimensions, tolerances, and end use, whether that is a single part or a full run.
Do you have a minimum order quantity for custom parts?
No, we take on both single prototype parts and larger production runs. The right approach depends on your specifications, not a fixed minimum.
Which materials work best for a custom metal part?
That depends on how the part will be used. Tell us the application, the environment, and the load or corrosion resistance you need, and we will help you choose between steel, stainless steel, and aluminum.
Can I see examples of custom parts you have built before?
Yes, our Showcase of Work page includes past custom fabrication projects across a range of industries.
