What is custom metal fabrication?
Custom metal fabrication is the process of cutting, forming, welding, and finishing raw metal into a part or assembly built to a specific drawing. Carbotech Manufacturing does this work in aluminium, stainless steel, and mild steel at its Roebuck, South Carolina shop, from single pieces through repeat production runs.
Buying fabrication is mostly a question of trust. You send a drawing and wait to find out whether the parts fit. Carbotech Manufacturing removes some of that risk by keeping every operation in one building. Cutting, sawing, welding, machining, assembly, and paint all happen at the Roebuck plant under one quality system. Nothing ships to a second vendor and comes back late. Mechanical and electrical engineers work on site, so a drawing with a problem gets flagged before anyone cuts material.
What every custom metal fabrication job includes
- Review of your drawings before any material gets cut
- Laser cutting up to one inch thick on a five-foot by ten-foot bed
- Sawing, plasma cutting, and 60-ton ironworker capacity for heavier sections
- Welding in aluminium, stainless steel, and mild steel
- Machining for features the cutting operations cannot hold
- Mechanical assembly and fit-up in the same building
- In-house painting and finish
- Inspection under a quality system built to ISO 9001:2015 standards
How Carbotech runs a fabrication job
Every shop says it delivers on time. What matters is where the job can stall. We keep each step in one building so there is no outside vendor holding the schedule.
Drawing review
We read your prints first and raise questions about tolerances, materials, and weld callouts before quoting.
Quote and lead time
You get pricing and a delivery date in writing. We quote what we can hold.
Cutting and forming
Material moves through the laser, saw, plasma cutter, or ironworker depending on thickness and section.
Welding and machining
Fabricators weld to your specification, and machining handles features the cutting operations cannot produce.
Finish and inspection
Parts get assembled, painted, and checked against the drawing before shipment.
Why do fabricated parts come back wrong?
Most rejected parts trace to three causes. Tolerances were never discussed before cutting, the drawing left a weld or finish callout open to interpretation, or the job passed through several shops with nobody owning the result. Catching those gaps at drawing review costs far less than scrapping a finished assembly.
Reference — AWS D1.1 structural welding code
Welding quality is defined by code, not by eye
A sound-looking weld and a qualified weld are different things. AWS D1.1, the structural welding code published by the American Welding Society, sets out how welding procedures and welders get qualified and how finished welds are inspected and accepted. Project contracts routinely reference it.
That distinction matters when you buy fabrication. Ask any shop how it qualifies procedures, how it documents inspection, and what happens when a weld gets rejected. Carbotech Manufacturing runs a quality management system built to ISO 9001:2015 standards, with inspection at each handoff rather than a single check at the end.
Who does custom metal fabrication near Spartanburg, SC?
Carbotech Manufacturing runs a 14,000-square-foot fabrication plant at 129 Old Airport Road in Roebuck, inside Spartanburg County. The shop opened in 2023 and is backed by a Canadian parent company that has built industrial equipment for sawing and planing mills since 1987.
Frequently asked questions
Both. The laser needs no tooling, so a single part carries no setup penalty the way a stamped or cast part would. Repeat runs move through the same quality system, which keeps the hundredth piece matching the first. Tell us the quantity when you send the drawing.
Aluminium, stainless steel, and mild steel. Each behaves differently through cutting, welding, and finishing, and the right choice usually depends on load, corrosion exposure, weight, and washdown requirements. We discuss that during drawing review rather than assuming the material called out is the best fit.
Yes. Painting happens at the Roebuck plant rather than at an outside coater, which removes a shipping leg and a handoff from the schedule. Parts move from weld to assembly to finish inside one building, and the finished assembly gets checked against your drawing before it ships.
Yes. Machining runs alongside cutting, welding, and assembly at the Roebuck plant. It handles features that laser cutting, sawing, and plasma cutting cannot produce, including close-tolerance holes and finished faces. Combining those operations under one roof avoids shipping a partly finished part to a second shop.
Send your drawings and the quantity you need. Jon Comber handles scope and quoting directly rather than routing questions through a sales desk, so answers come from someone who knows what the shop can hold. Standard payment terms are Net 30 once an account is open.
Ready to get your parts made?
Custom metal fabrication works best when one shop owns the drawing review, the cutting, the welding, the finish, and the inspection. Carbotech Manufacturing keeps all five in one building in Roebuck, South Carolina. Send a print and find out what the schedule looks like.
