Fabrication is the other half of making metal parts. Where machining carves a part from a solid block, fabrication builds one up from sheet, plate and structural stock — cut to shape, bent on the brake, welded into an assembly and finished for service. Brackets, panels, enclosures, guards, chassis, frames and weldments all come from this side of manufacturing, and most real products need both sides. KALIV manages fabrication the same way as everything else: quoted from your drawings, placed with the fabrication shop in our network that fits the work, and managed through delivery. From a single repaired bracket to a scheduled run of finished enclosures, the work is quoted from the drawing and delivered to it — with one company accountable for the whole package.

What fabrication covers
Fabrication work starts flat and ends three-dimensional. Sheet and plate get cut to profile, holes and cutouts included; formed parts pick up their bends on the press brake; and where a part is really several pieces, welding joins them into one weldment. The output ranges from simple one-bend brackets through formed enclosures with hardware installed, up to welded frames and bases that carry entire machines. If the part in your head is made of bent sheet metal or welded steel rather than carved from a block, it is a fabrication job — and if it is some of each, that is normal, and exactly what a managed multi-process service coordinates well.
Fabrication or machining — which does the part want?
The honest rule: thin and hollow wants fabrication, thick and precise wants machining. An enclosure milled from solid would cost a fortune in material and machine time; the same enclosure bent from sheet costs a fraction. A bearing bore held to a tight fit has no business being a welded guess; it belongs on a machine. Many parts split the difference — fabricate the body, machine the features that matter — and that split is a design decision worth making early, because it drives cost more than almost anything else on the drawing. Send the part before the design hardens and KALIV will tell you which processes it wants, with the reasoning attached.
How a fabrication job is evaluated
A fab quote reads the drawing differently than a machining quote. First the material: alloy, gauge or thickness, and how much sheet the flat pattern consumes. Then the operations: how many cuts, how many bends, whether bends are simple or close-coupled, how much welding and in what positions. Then the callouts that add care — flatness on a mounting face, hole positions that locate other parts, cosmetic surfaces that must stay unmarked. Those answers also decide which partners are candidates, because fabrication shops specialize as much as machine shops do. A complete drawing with bend directions, weld symbols and critical dimensions flagged gets a faster, firmer number.
Cutting and forming
Profiles are cut on a laser or a waterjet — a laser for speed and edge quality on material up to roughly half an inch, a waterjet when the material is thick, reflective or heat-sensitive enough that a laser's heat-affected edge would matter — and then the press brake does what defines sheet metal work: accurate bends in accurate places. Forming has its own physics — material stretches at a bend, so flat patterns must account for it, and inside radii follow tooling and material rather than wishful thinking. Designs that respect a few rules form cleanly and cheaply: consistent bend radii, holes kept clear of bend lines, flanges long enough to grip. When a drawing fights those rules, KALIV flags it at quoting and proposes the small change that saves the part from being expensive forever.
Welding and weldments
Welding turns pieces into structures — frames, bases, brackets and housings that machining alone could never produce economically at size. Good weldment work is mostly preparation: joints designed for access, parts fixtured so the assembly comes out square, and a welding sequence that manages heat, because metal moves when you weld it and pretending otherwise produces banana-shaped frames. Steel, stainless and aluminum each behave differently, and the process gets matched to material and loads. Structural welds are sized to the job; cosmetic welds dressed where the eye lands. The standard KALIV holds placements to is the only one that matters: square, sound and to the drawing.
Honest tolerances for formed and welded parts
Formed and welded parts hold looser tolerances than machined ones, and a drawing that admits this up front produces cheaper, better parts. Sheet metal bends hold position within forming tolerances, not machining tolerances; weldments move with heat no matter how careful the sequence. The professional answer is not tighter numbers on the print — it is design that puts precision only where function needs it: slotted holes where bolts just need to land, machined features where fits are real, weld-then-machine where a face must be truly flat. Specify a fabricated part like a machined one and you pay machining prices for it; specify it honestly and it does its job for a fraction.
Weld first, machine second
One of the most valuable sequences in manufacturing: build the weldment, then machine the surfaces that matter. A welded base whose mounting pads must sit flat, a frame whose bearing bores must align across a span, a fixture plate needing a true reference face — welded as structures, stress-relieved as required, then machined so critical faces and bores are cut after the metal has finished moving. That sequence produces alignment no amount of careful welding can match, and coordinating it — sometimes across a fabrication partner and a machining partner, with the schedule and the drawings kept coherent between them — is squarely KALIV’s job, not yours.
Finishing and protection
Fabricated parts usually live where people see them and weather reaches them, so finishing is part of the job, not an afterthought. Welds are cleaned and dressed to the level the part calls for; steel headed outdoors or into wash-down service gets painted or coated — powder coat and wet paint for cover and color, plating and galvanizing where the environment demands more; stainless gets cleaned and passivated so it stays stainless; aluminum gets anodized for color and corrosion resistance. KALIV coordinates finishing with the build so masking protects threads and mating faces, and what arrives at your dock is done — not a bare weldment with a second project attached.
What drives fabrication cost, and what to send
Fabrication pricing follows material, cut length, bend count, weld inches and finishing — each visible on a complete drawing. Quantity discounts are real because brake setups and weld fixtures amortize across the run, and placement matters here as much as anywhere: work priced at a shop tooled for it beats work forced through the wrong one. To quote, send the model or drawings with material and thickness, bend directions, weld requirements and the finish, plus quantity and the need date. Got only a sketch or a broken original? Send that — turning rough reality into a proper drawing is a service, and it is how one-off repairs become reorderable parts. Photos help more than most people expect, too: a few clear shots of where the part bolts on, what it clears and what it carries often settle questions a drawing alone leaves open.
Common Questions on Fabrication
Who actually makes my parts?
Vetted partner shops in the KALIV network, each chosen for the specific job — a volume-turning specialist for screw machine work, a fabrication shop for weldments, and so on. KALIV quotes the work, places it, manages it and stands behind the result. You get one point of contact and one accountable company; we handle the sourcing and coordination.
Why not go directly to a machine shop?
For a single simple part, you can. The value shows up when a job spans processes — machined parts, fabricated frames, printed housings, assembly — or when you would otherwise be auditioning shops you cannot easily evaluate. No single shop is best at everything; a managed network places each piece where it fits, and you carry one purchase order instead of five vendor relationships.
How is quality controlled across different shops?
Requirements travel with the job: drawings go out with critical dimensions flagged, first articles are approved before production continues, and inspection results come back with the parts. Recurring orders re-run a proven recipe at a shop that has already demonstrated it. If something arrives wrong, KALIV owns the fix — that is what one accountable partner means.
