Carbotech Manufacturing | Metal Fabrication in Roebuck, South Carolina
A fabrication quote is only as accurate as the request behind it. A drawing without a revision, a material callout without a grade, or a blank quantity can send the job back for questions before anyone prices it.
This article covers what to include in a custom metal fabrication quote request and why 2026 steel price data makes material details worth getting right. Carbotech Manufacturing is a full-service metal fabrication shop in Roebuck, South Carolina, cutting, welding, machining, assembling, painting, and inspecting in one 14,000 square foot building.
Why Incomplete Quote Requests Slow a Job Down
A fabricator prices what the drawing and the request describe. When a detail is missing, the shop has two options: ask or assume. Questions add time before the quote, and assumptions can surface later as parts that miss what the buyer needed.
Carbotech Manufacturing reads prints before quoting and raises questions about tolerances, materials, and weld callouts at that stage. A complete request leaves fewer questions open at that step.
What should I send a fabricator to get a quote?
Send the drawings with the current revision, the material and thickness, the quantity, and the date parts are needed. Add tolerances, weld callouts, and finish requirements if the drawing does not already state them. Carbotech Manufacturing in Roebuck, South Carolina asks for the drawings and the quantity to start a custom metal fabrication quote.
What Each Detail Tells the Fabricator
Drawings and revision. The drawing defines the part, and the revision confirms which version gets built. Carbotech confirms the drawing revision before quoting build-to-print work.
Material and thickness. Aluminum, stainless steel, and mild steel each behave differently through cutting, welding, and finishing. Thickness and section help decide which process runs the part. At Carbotech, a Mazak 510 laser cuts up to one inch, and heavier sections move to the saw, plasma cutter, or 60 ton ironworker.
Quantity. State whether the order is a single part or a repeat run. Carbotech nests larger laser runs across the sheet to reduce scrap.
Tolerances. Call out the dimensions that matter to fit and function. Machining handles features that cutting cannot produce, including close-tolerance holes and finished faces.
Weld and finish callouts. Weld requirements belong on the drawing, along with any code the contract references, such as AWS D1.1 from the American Welding Society. Paint and finish requirements belong there too.
The need-by date. A target date lets the shop check the schedule against capacity. Carbotech quotes delivery dates in writing.
How much have steel prices changed over the past year?
U.S. Bureau of Labor Statistics data published in September 2026 show the Producer Price Index for steel mill products rose about 23 percent from August 2025 to August 2026. The index climbed from 308.8 to 381.2, its highest reading since August 2022. Recent months in the series remain subject to revision.
What Steel Price Movement Means for a Quote Request
The Federal Reserve Bank of St. Louis publishes the steel mill products price index in its FRED database, using BLS data. BLS released the August 2026 figure in September 2026.
The index tracks prices that domestic mills receive, so it measures raw material rather than finished parts. A fabricated part also carries cutting, welding, machining, finish, and inspection. The index still shows that material is a moving input.
That makes exact material callouts more useful in a quote request. A grade, a thickness, and a quantity let the fabricator price the stock the job needs. If an equivalent material is acceptable, saying so up front gives the shop room to quote it.
What drawing problems cause fabricated parts to be rejected?
According to Carbotech Manufacturing, most rejected parts trace to three causes. Tolerances were not discussed before cutting, a weld or finish callout was left open to interpretation, or the job passed through several shops with nobody owning the result. Catching those gaps at drawing review costs less than scrapping a finished assembly.
How Drawing Review Works Before the First Cut
At Carbotech, drawing review is the first step in custom metal fabrication. Mechanical and electrical engineers work on site, so a drawing with a problem can be flagged before material is cut.
From there, the job stays in one building. Material runs through the laser, saw, plasma cutter, or ironworker depending on thickness and section. Carbotech’s laser cutting services run on the Mazak 510. For how those processes compare, see laser cutting vs. plasma cutting. Fabricators weld to the customer’s specification, and machining adds features the cutting operations cannot produce. The shop then assembles, paints, and checks parts against the drawing before shipment.
Carbotech runs a quality management system built to ISO 9001:2015 standards, with the certification audit targeted for Q1 2027. Inspection happens at each handoff rather than in a single check at the end.
Can a metal fabrication shop quote a single part?
Carbotech Manufacturing in Roebuck, South Carolina quotes single parts as well as repeat production runs. Laser cutting uses no dies or punches, so a single laser-cut part carries no die cost the way a stamped part would. Buyers should include the quantity with the drawing, since larger runs get nested differently.
Single Parts, Repeat Runs, and Larger Assemblies
Repeat runs at Carbotech follow written procedures with inspection at each handoff, which is how the shop works to keep later pieces consistent with the first. For ongoing build-to-print work, contract manufacturing covers first-article checks and repeat production. Before outsourcing that work, see how to choose a contract manufacturer.
Some fabricated parts are components of something larger, such as a conveyor or platform. When that is the case, the inputs for the full system matter as well. Custom material handling systems: what to define before you build covers that side of the scope.
Frequently Asked Questions
What file format should I send a metal fabricator?
Send drawing files in the format your design system produces, along with the material, thickness, and quantity. Carbotech Manufacturing in Roebuck, South Carolina confirms the file format it needs when drawings come from a system the shop has not worked with before. That way, the format is settled before quoting.
Should a fabrication quote request include a delivery date?
A fabrication quote request should include the date parts are needed, so the shop can check the schedule against capacity. Carbotech Manufacturing quotes delivery dates in writing, based on real capacity rather than optimism. The drawing revision and quantity belong in the same request, since both affect the schedule.
What is drawing review in metal fabrication?
Drawing review is the step where a fabricator reads the prints before quoting and raises questions about tolerances, materials, and weld or finish callouts. At Carbotech Manufacturing in Roebuck, South Carolina, drawing review comes first. Engineers on site can flag a drawing problem before any material is cut.
Can one shop cut, weld, machine, and paint the same part?
One shop can cut, weld, machine, and paint the same part if it runs all four operations in house. Carbotech Manufacturing does all four in one 14,000 square foot plant in Roebuck, South Carolina. Painting happens in house rather than at an outside coater, which removes a shipping leg from the schedule.
