Sheet Metal Cost Guide
Sheet metal cost: cutting, bending, and hardware.
A sheet metal price is a stack of small metered operations — cut path, bend hits, inserts, finish. This guide prices each layer and shows how quantity collapses the total.
The price is a stack of operations
Nobody quotes “a bracket” — the quote meters every operation the part passes through: cutting, forming, hardware, finish. Understand the three layers and every sheet metal price becomes predictable.
$80–150
One-time: setup
Nest programming, press-brake setup per bend tool, and first-article inspection. At one part it IS the price; at a hundred parts it fades to pennies.
$0.40–1.50
Per part: metered operations
Every feature is a metered operation — laser minutes for the cut path, that much per bend hit, $0.40–0.90 per inserted fastener. Simple flat parts are almost pure material.

The quantity collapse
The reference bracket below drops from ~$88 at one piece to ~$9.80 at a hundred. Sheet metal rewards batching harder than any other prototype process.
Four ways off the sheet — and what each costs
Cutting is the first operation on every quote, and the method is usually the shop’s call — but knowing the economics tells you what your geometry will cost before you upload it. Fiber laser is the default; the other three earn their place in specific corners.
| Method | Thickness sweet spot | Tolerance | Edge quality | Relative cost | Best for |
|---|---|---|---|---|---|
| Fiber laser | 0.5–12 mm (steel to ~20 mm) | ±0.1 mm | Clean, minimal heat mark | $ — default | Nearly everything. Fastest and cheapest for the thin-to-medium gauges that make up most sheet metal work — assume laser unless something below applies. |
| Turret punch | 0.5–3 mm | ±0.1 mm | Slight shear burr | $ at volume | High-volume thin parts with standard holes — and the only way to get formed features (louvers, lances, countersinks, knockouts) in the same hit. |
| Waterjet | 1–100+ mm, any material | ±0.1–0.2 mm | No heat-affected zone at all | $$$ — slow | Thick plate, heat-sensitive alloys, pre-finished or pre-anodized sheet, and stacked multi-layer cutting. Pay for it only when heat is the enemy. |
| Plasma | 3–40 mm steel | ±0.5–1 mm | Dross + heat-affected zone | $ for thick | Structural steel where the edge gets welded or ground anyway. Cheapest way through thick carbon plate; wrong tool for precision holes. |
Relative cost is per part for typical sheet gauges, cutting included through deburr. Method choice is confirmed at engineering review — geometry, alloy, and quantity can move the answer.
Quantity collapses the price
Reference part: a 2 mm aluminum 5052 bracket, 200 × 120 mm flat pattern, 4 bends, 2 M4 PEM nuts, black powder coat. Same part, four quantities — watch setup vanish from the bill.
Formed aluminum bracket — unit price by quantity
Where the money goes at each quantity — the same bill, split by operation:
At one part, setup and programming is half the bill and material barely registers. By five hundred, the ratios invert: material is the biggest slice and setup is a rounding error. Practical rule: if you need 8 parts, price 10 — and if a revision is coming, prototype at low quantity first. The same staging logic applies across processes; see the prototype manufacturing page for how teams sequence it.
Typical US job-shop pricing for the reference geometry, rounded — not a quote. Your part is priced on its own geometry and confirmed by engineering review.
Bends and hardware: where quotes quietly grow
Cutting is cheap and predictable — forming and fasteners are where two similar-looking parts end up $20 apart. Six bend rules first, then what each inserted fastener actually costs.
- A bend is a hit plus a setup. Each bend runs roughly $0.40–1.50 per part in brake time, but every UNIQUE tool setup adds $40–80 once. Four bends sharing one setup beat two bends needing two.
- Same radius, same direction = one setup. Design every bend to the shop-standard inside radius (usually 1× material thickness) and keep them in as few planes as possible.
- Minimum flange is 4× thickness. A flange shorter than about 4× thickness cannot sit on standard dies — it needs special tooling or post-machining, and the quote shows it.
- Tight radii cost, generous radii are free. Inside radius at 1× thickness bends in one hit. Below that, the brake coins or bumps the bend — more hits, more time, and cracking risk in hard alloys.
- 6061-T6 cracks where 5052 bends. T6 aluminum needs a 2–3× thickness radius or it splits at the bend line. If the part is mostly bent geometry, 5052-H32 is the cheaper and safer sheet.
- Tolerance across a bend is ±0.25 mm, not ±0.1. Springback and material stretch make bend-to-hole dimensions inherently looser than cut features. Dimension critical holes from the same face and cut them after forming only if you must.
Threads and mounting points, priced installed:
| Hardware | Installed cost | Why it wins | When to spec it |
|---|---|---|---|
| Self-clinching nut (PEM) | ~$0.40–0.90 | Beats tapping below 1.5 mm sheet | Load-bearing machine threads in thin sheet — the default answer. Pressed in during fab, stronger than the sheet itself. |
| Self-clinching standoff | ~$0.50–1.20 | Replaces a loose spacer + screw | Mounting PCBs and panels at a set height inside enclosures — one pressed part instead of three loose ones per hole. |
| Rivet nut (threaded rivet) | ~$0.35–0.80 | Installs blind, even after finishing | Closed sections and field installation — sets from one side with a hand tool, so it also rescues holes after powder coat. |
| Weld stud | ~$0.60–1.50 | Invisible from the show face | Cosmetic panels where no fastener may show on the A-side. Adds a welding operation and post-clean, so only where looks demand it. |
| Tapped hole in sheet | ~$0.30–0.60 | Needs ≥1.5 mm of thread depth | Fine in 2 mm+ sheet with 2–3 threads of engagement. In thin gauge the threads strip — that is what inserts are for. |
Installed prices per fastener at moderate quantity, hardware included. Standard PEM catalog items only — specials and metric/imperial mixes add sourcing time.
Finishing: lot charges vs per-part adders
Every finish has two prices — a per-part adder and a lot minimum. At prototype quantity the minimum dominates (five powder-coated parts cost almost the same as one); at volume only the adder matters.
| Finish | Per-part adder | Lot minimum | When to spec it |
|---|---|---|---|
| Deburr & tumble | Included | — | Every part, every quote — safe-to-handle edges are the baseline, not an option. |
| Powder coat | +$4–12 / part | ~$120 lot min | The workhorse cosmetic + corrosion finish for steel and aluminum. Cheapest color at volume; the lot minimum stings at qty 1–5. |
| Anodize, clear (Type II) | +$3–9 / part | ~$100 lot min | Aluminum only. Hard, thin, conductive-neutral surface that keeps machined looks — the default for instrument and enclosure work. |
| Zinc plate + clear chromate | +$2–6 / part | ~$90 lot min | Corrosion protection on carbon steel brackets and chassis parts that live inside an assembly. |
| Chem film (Alodine) | +$2–5 / part | ~$80 lot min | Aluminum that must stay electrically conductive — grounding surfaces, EMI shields, and under paint as a primer. |
| Brushed / grained | +$3–8 / part | — | Cosmetic stainless and aluminum show surfaces. Manual labor — price scales with visible area, not part count. |
| Silk screen | +$1–3 / part | ~$50 screen setup | Legends, logos, and safety markings on panels — one screen setup per artwork, then cheap per hit. |
Adders are for palm-to-laptop size parts at moderate quantity. Masking (threads, grounding surfaces, press-fit bores) is the hidden finishing cost — every masked feature is manual labor, so call out only the faces that truly need protection.
Sheet materials: cost, gauge, and the bend-radius rule
Material choice sets a third of the price at volume — and one forming property most CAD models ignore: the minimum inside bend radius, in multiples of thickness (t). Tighter than the alloy allows means cracked bends or special tooling.
| Material | Relative cost | Common gauge | Min bend radius | Worth knowing |
|---|---|---|---|---|
| Aluminum 5052-H32 | $$ | 0.5–6 mm | 1× t | The forming default: bends tight radii without cracking, welds, anodizes. Start here for any bent aluminum part. |
| Aluminum 6061-T6 | $$ | 0.5–6 mm | 2–3× t | Stronger and machinable, but cracks on tight bends — pick it for flat or lightly-formed parts that also get machining. |
| Cold-rolled steel (CRS) | $ | 0.5–3 mm | 1× t | The cheapest sheet you can buy. Rusts bare — budget a finish (powder coat or zinc) into every CRS part. |
| Galvanneal steel | $ | 0.5–3 mm | 1× t | Zinc-iron coated CRS that paints beautifully — enclosure shops run it by the ton. Coating survives bending. |
| Hot-rolled steel (HRPO) | $ | 3–10 mm | 1.5× t | Structural thickness — weldments, frames, brackets that carry real load. Plasma and laser territory. |
| Stainless 304 | $$$ | 0.5–6 mm | 1–1.5× t | No finish needed, food-safe, strong springback — brakes compensate, but bend tolerances open up slightly. |
| Stainless 316 | $$$$ | 0.5–6 mm | 1–1.5× t | Marine and medical grade. Pay the ~30% premium over 304 only when chlorides or biocompatibility demand it. |
| Copper C110 | $$$$$ | 0.5–4 mm | 1× t | Busbars and grounding parts. Soft to form, gummy to cut — waterjet or punch beats laser on reflective copper. |
The bend-radius column is the one that bites: model every bend at 1× thickness in 5052 or steel and your CAD goes straight to the brake. Model a 6061-T6 part the same way and the first article comes back cracked. Full datasheets live in the materials library.
Cost bars are relative sheet price per kg (copper C110 = 100), typical distributor pricing, September 2026. Gauge ranges are the commonly stocked window, not process limits — thicker runs as plate work.
Sheet metal cost — FAQ
How much does sheet metal fabrication cost?
A useful mental model: a one-time setup of $80–150 (programming, brake setup, first article), plus metered operations per part — laser time for the cut path, $0.40–1.50 per bend, $0.35–1.50 per inserted fastener, and a finishing adder. A palm-size 2 mm aluminum bracket with 4 bends, 2 PEM nuts, and powder coat runs about $88 at one piece and $9.80 each at a hundred.
Why is one sheet metal part so expensive, and how fast does the price drop?
At quantity one, setup is most of the bill — the metal and machine time in a single bracket are only a few dollars. The jump from 1 to 10 pieces typically cuts unit price by around 70%, and 10 to 100 halves it again as setup amortizes and nesting gets efficient. If you need 8 parts, price 10 — the extras are nearly free.
Which cutting method is cheapest — laser, waterjet, plasma, or punching?
Fiber laser is the default and usually the cheapest for sheet up to about 12 mm, holding ±0.1 mm with a clean edge. Turret punching wins at high volume in thin gauge and is the only way to get formed features like louvers in the same operation. Plasma is the budget route through thick structural steel at looser tolerance. Waterjet costs the most per minute — pay for it when heat would damage the material or the part is very thick.
How much does each bend cost?
Roughly $0.40–1.50 per bend per part in press-brake time, plus $40–80 once for every unique tool setup. Bend count matters less than setup count: four bends sharing one radius and direction cost less than two bends needing two different tools. Keeping every bend at the standard inside radius (1× material thickness) is the single cheapest design choice in sheet metal.
Should I use PEM inserts or tapped holes?
Depends on sheet thickness. At 2 mm and up, a tapped hole (~$0.30–0.60) gives 2–3 threads of engagement and works fine. Below about 1.5 mm the threads strip, and a self-clinching PEM nut (~$0.40–0.90 installed) is stronger than the sheet itself. Rivet nuts install blind from one side — the rescue option for closed sections or holes added after powder coating.
How much does powder coating add?
Typically $4–12 per part with a lot minimum around $120, which is why it stings at quantity 1–5 and disappears into the price at 100. Clear anodize on aluminum runs $3–9 per part with a similar minimum. If a prototype just needs corrosion protection and looks are secondary, bare 5052 or stainless with a tumbled finish ships fastest and cheapest.
