9 Ways to Reduce Sheet Metal Fabrication Costs Without Sacrificing Quality

Every sheet metal buyer wants the same thing: the part they need at the lowest cost that doesn’t compromise quality. The good news is that a large share of a part’s cost is set not by the shop’s hourly rate, but by design and specification decisions — most of which are within your control.

Tighten a tolerance that didn’t need tightening, specify a material grade above what the application requires, or design a bend the brake can’t reach efficiently, and you’ve quietly added cost. Conversely, a handful of deliberate decisions can cut 10–30% out of a part’s price without touching its function.

This guide walks through nine proven ways to reduce sheet metal fabrication cost — the levers our engineering team uses when we run a DFM review — and explains why each one works.

1. Choose the Right Material — Not the Premium One

Material is often the single largest cost component, and over-specification is the most common waste. Engineers frequently default to a higher grade “to be safe” when a standard one would perform identically.

• Don’t specify 316 stainless if 304 meets the corrosion requirement — 316 costs noticeably more (see our 304 vs 316 guide).
• Don’t specify 6061 aluminum if 5052 or 3003 suits the part — match the alloy to the actual need (see our aluminum grades guide).
• For indoor enclosures, powder-coated cold-rolled steel is often far cheaper than stainless.

The lever: specify the material the application genuinely requires, not the one that feels safest. Ask your fabricator for a material recommendation if unsure.

2. Loosen Tolerances That Don’t Need to Be Tight

Tight tolerances are expensive — they require more precise processes, more setup, more inspection, and higher scrap rates. And most features on most parts don’t need them.

A ±0.005” tolerance where ±0.020” would work means you’re paying for precision the part will never use. Standard sheet metal tolerances are economical; every tolerance tighter than standard adds cost.

The lever: apply tight tolerances only to the specific features that need them (mating surfaces, critical holes), and let everything else sit at standard tolerance. Don’t blanket-tighten the whole drawing.

3. Design Bends the Brake Can Actually Make

Bends are where a lot of hidden cost lives. A few rules:

• Keep bend radii consistent across the part — every unique radius can mean a different tool and another setup.
• Use the shop’s standard bend radius rather than an arbitrary one.
• Avoid bends too close to holes or edges — they distort, causing rework. Respect minimum distances (see our press brake bending defects guide).
• Watch for bends the brake can’t reach — a flange that collides with the tooling forces a workaround or a redesign.

The lever: standardize radii, respect minimum bend-to-feature distances, and confirm complex bends are tool-accessible before release.

4. Use Standard, Off-the-Shelf Hardware

Custom or exotic fasteners, standoffs, and inserts add cost and lead time. Self-clinching hardware (PEM-style) installed in-house is economical; specialty hardware sourced specially is not.

The lever: specify standard, readily available hardware wherever possible. Consolidate to fewer unique part numbers — buying one fastener type in volume beats five types in small quantities.

5. Right-Size the Finish

Finishing is frequently over-specified. A cosmetic-grade finish on a part that lives inside a sealed enclosure is wasted money; so is a tight color match where standard would do.

• Does an internal custom sheet metal bracket need powder coat, or just deburring?
• Does the edge need a polished break, or just “break all sharp edges”? (See our deburring guide.)
• Is anodizing required, or is mill finish acceptable?

The lever: specify the finish the function and visibility require — no more. Distinguish cosmetic surfaces from hidden ones on the drawing.

6. Design for Efficient Nesting

Parts are cut from sheet stock, and the less material wasted between parts, the lower the material cost. Part geometry and size affect how tightly parts “nest” on a sheet.

• Slightly adjusting a part’s dimensions can sometimes dramatically improve yield.
• Designing parts that tessellate (fit together) reduces scrap.
• Ordering in quantities that fill standard sheet sizes avoids paying for offcuts.

The lever: ask your fabricator about nesting efficiency — sometimes a small, function-neutral dimension change significantly cuts material cost across a production run.

7. Reduce the Number of Parts and Operations

Every separate part is its own material, cutting, forming, and handling cost — and every assembly step adds labor. Consolidation pays.

• Can two brackets become one bent part?
• Can a fastened joint become a formed feature or a tab-and-slot?
• Can you eliminate a secondary operation through smarter design?

The lever: look for opportunities to combine parts and eliminate operations. Fewer parts and fewer steps almost always means lower cost — and often higher reliability.

8. Order in the Right Quantities

Setup cost (programming, tooling, first-article) is amortized across the run. A part that’s expensive in quantity 10 is much cheaper in quantity 500 because the setup is spread further.

• If your demand is steady, ordering in larger batches lowers per-unit cost.
• Blanket orders with scheduled releases can capture volume pricing while managing inventory.
• Avoid tiny, frequent reorders that re-incur setup each time. (See our MOQ guide.)

The lever: consolidate demand into efficient batch sizes, and discuss blanket-order arrangements with your supplier for ongoing parts.

9. Get a DFM Review Before You Release

This is the meta-lever that captures all the others. A design-for-manufacturability (DFM) review — ideally with your fabricator, early — catches the cost drivers above before they’re locked into a released drawing and a quote.

A good fabricator will flag the over-tight tolerance, the problematic bend, the premium material that isn’t needed, and the nesting opportunity — turning a series of small savings into a meaningfully lower price.

The lever: treat DFM as a step in your process, not an afterthought. The earlier a cost driver is caught, the cheaper it is to fix.

The Cost Drivers, Summarized

Lever	What it cuts
Right material	Material cost (over-specification)
Looser tolerances	Machining, inspection, scrap
Brake-friendly bends	Setup, rework
Standard hardware	Component cost, lead time
Right-sized finish	Finishing labor & material
Efficient nesting	Material waste
Fewer parts/operations	Material + assembly labor
Right quantities	Setup amortization
Early DFM	All of the above

How DRAmetal Helps

DFM is built into how we quote. When you send us a drawing, our engineering team reviews it for exactly these cost drivers — and tells you where you can save without compromising the part:

• Material recommendations matched to your actual requirement
• Tolerance and bend feedback to avoid paying for precision you don’t need
• Hardware and finish guidance to right-size both
• Nesting and quantity advice to lower material and setup cost

We do this because a part designed for manufacturability is cheaper, faster, and more reliable — which is better for everyone. For related guidance, see our guides on how to choose a sheet metal supplier, the sheet metal RFQ checklist, the design for manufacturing sheet metal guide and the 17-point DFM checklist.

Want to review your part’s cost drivers? Send us your drawing. The initial response target is within 24 working hours; DFM, cost-driver feedback and quotation timing depend on file completeness and engineering scope.
