What is structural steel fabrication?
Structural steel fabrication is the cutting, drilling, and welding of beams, plate, and sections into load-bearing components built to an engineered drawing. Carbotech Manufacturing does this work at its Roebuck, South Carolina plant, producing platforms and structural components for industrial applications in aluminium, stainless steel, and mild steel.
Structural work carries weight, which changes the stakes. A cosmetic part that comes back slightly off gets reworked. A support that comes back slightly off can hold up an entire installation or fail under load. Carbotech Manufacturing keeps cutting, drilling, welding, assembly, and paint in one building, with mechanical and electrical engineers on the same floor as the fabricators. Questions about a connection or a load path get answered before the steel gets cut.
What our structural steel fabrication work includes
- Platforms and structural components for industrial applications
- Supports and framing for conveyors and material handling equipment
- Laser cutting up to one inch thick on a five-foot by ten-foot bed
- Hyd-Mech saw, Hypertherm plasma cutter, and 60-ton ironworker for heavier sections
- Welding in aluminium, stainless steel, and mild steel
- Mechanical assembly and fit-up before shipment
- In-house painting and finish
- Inspection under a quality system built to ISO 9001:2015 standards
How structural work runs through the Roebuck plant
Structural jobs stall in familiar places. A connection detail goes unresolved, a member arrives from an outside shop late, or nobody checks fit until the crew is standing on site. We keep the whole sequence in one building.
Drawing and load review
Our engineers read the drawing, the connections, and the load callouts before quoting.
Quote and schedule
You get pricing and a delivery date in writing, based on real shop capacity.
Cutting and prep
Sections run through the saw, plasma cutter, ironworker, or laser depending on thickness and profile.
Welding and fit-up
Members get welded and assembled, then checked against the drawing rather than at the job site.
Finish and delivery
Steel gets painted and shipped, with installation available on turnkey projects.
Why does structural steel fail inspection?
Most rejections trace to workmanship at the connections rather than the members themselves. Undersized welds, poor fit-up that leaves gaps, missing bolt holes, and members cut short all show up at erection. Checking fit in the shop, where a member can still be corrected, costs far less than discovering the problem with a crane on site.
Reference — AISC 360 specification for structural steel buildings
Load-bearing steel is governed by specification
Decorative metalwork answers to the eye. Structural steel answers to a specification. AISC 360, published by the American Institute of Steel Construction, sets the generally applicable requirements for the design and construction of structural steel buildings and other structures. Your engineer of record works to it, and your fabricator has to build what that engineer specified.
The practical point for a buyer is straightforward. Send the stamped drawings, the connection details, and any project specification that applies. Carbotech Manufacturing runs a quality system built to ISO 9001:2015 standards, with inspection at each handoff rather than a single check before shipment.
Who does structural steel fabrication in Upstate South Carolina?
Carbotech Manufacturing fabricates structural steel at a 14,000-square-foot plant at 129 Old Airport Road in Roebuck, inside Spartanburg County. The shop opened in 2023, backed by a Canadian parent company building industrial equipment for sawing and planing mills since 1987.
Frequently asked questions
Platforms, supports, framing, and structural components for industrial applications. Much of the work supports conveyors and material handling equipment we also build. Send the drawing and the application, and Jon Comber will confirm whether the job fits the shop before quoting anything.
The laser cuts plate to one inch on a five-foot by ten-foot bed. A Hyd-Mech saw, a Hypertherm plasma cutter, and a Piranha 60-ton ironworker handle heavier sections and profiles. Send your member sizes with the drawing and we will confirm what the shop can process.
Yes. The shop works aluminium, stainless steel, and mild steel, and welders cover all three. Material choice usually comes down to load, corrosion exposure, weight, and washdown requirements. We discuss that at drawing review rather than assuming the specified material is the best fit.
Installation is available on turnkey projects, where one team carries the work from drawing through installed equipment. Scope varies by job, so confirm site work with Jon Comber when you send drawings. Machines we build carry a 12-month warranty, and we stand behind the fabrication itself.
Send drawings, member sizes, material, quantity, and the date you need steel on the ground. Jon Comber handles scope and quoting directly rather than routing it through a sales desk. Standard payment terms are Net 30 once an account is open.
Ready to price your structural steel?
Structural steel fabrication works best when one shop cuts, welds, fits, finishes, and checks the same members. Carbotech Manufacturing keeps that sequence in one building in Roebuck, South Carolina. Send drawings and a date, and you get a schedule based on real capacity.
