Customer Reviews
Verified feedback from buyers across 30+ countries.
"Jack aus dem Engineering-Team hat uns deshalb im Rahmen einer DFM-Prüfung empfohlen, die Teile stattdessen mit Laserschneiden und CNC-Abkanten zu fertigen. Er hat uns die Vor- und Nachteile verständlich erklärt, sodass wir die Entscheidung gut nachvollziehen konnten. Wir hatten das Gefühl, dass nicht einfach nur ein Auftrag abgewickelt werden sollte, sondern dass wirklich nach einer passenden Fertigungslösung gesucht wurde."
"We evaluated four Asian suppliers before committing to these guys. What set them apart was the DFM feedback — they flagged a sharp internal radius that would have cracked in SPCC at 1.5mm and recommended 2mm with a 3× bend radius. First article laser cuts were within ±0.1mm, bend angles matched our GD&T callouts perfectly across a 300-piece pilot."
"Passed our incoming inspection first time. Also requested electropolishing instead of standard brushed finish and they adapted without any fuss. Quote turnaround was under 24 hours which helped us hit our project deadline. Would definitely order again."
Sheet metal fabrication services, all in one factory
Custom sheet metal fabrication is the process of cutting, forming and joining flat metal into finished parts, enclosures and assemblies. WERIX runs fiber laser cutting, CNC press brake bending, TIG and MIG welding, progressive die stamping and six surface finishes in one Dongguan factory — from a single prototype to 100,000+ units per order.
CNC sheet metal fabrication
Flat sheet cut and formed to order. No hard tooling, so a new revision costs nothing but the machine time.
Metal stamping and tooling
Hard tooling built in our own die shop. Uneconomic for a prototype, unbeatable once a part repeats at volume.
Around those processes: the laser takes sheet to 3,000 × 1,500 mm, the press brakes bend parts to 3,100 mm with a CNC backgauge at ≤0.02 mm repeatability, and the stamping lines run from 25T to 300T at up to 200 strokes a minute — with sheet metal welding and sheet metal assembly in the same building. Unless the drawing says otherwise we work to ISO 2768-1 class m general tolerances and call out anything tighter on the drawing.
Material and tolerance specifications follow ISO 2768-1 general tolerances, ASTM A480/A480M stainless sheet, ISO 9001 quality management, IEC 60529 enclosure IP ratings and EU RoHS restricted substances. Every production run ships with an inspection report written against your drawing.
12+ sheet metal grades on the floor, and the parts we cut from them
From 0.1 mm phosphor bronze strip for stamped contacts to 8 mm hot-rolled plate for machine bases. Common grades and thicknesses are held in stock for same-week cutting; anything outside that is sourced to order and confirmed at quotation. Name the operating environment and we will point at the cheapest grade that survives it.
Aluminum
Chosen for weight and formability, never for price. 5052 takes a tight bend without cracking, 6061 machines after forming.
- 5052 aluminumASTM B2090.5–5.0 mm
- Best bendability of the common alloys — it rarely cracks at a tight radius. Chassis, enclosures.
- 6061-T6 aluminumASTM B2091.0–6.0 mm
- Stiffer and machinable. Use it where a formed part also needs milled pockets or tapped bosses.
Two grades cover almost every corrosion problem. If you are unsure, 304 is the answer nine times out of ten.
- 304 stainless steelASTM A2400.5–4.0 mm
- The general-purpose stainless. Food equipment, medical housings, wash-down areas.
- 316L stainless steelASTM A2400.5–4.0 mm
- Molybdenum for chlorides. Coastal sites, chemical plant, marine electronics.
The volume metal — cheapest per kilo and the easiest to weld. SGCC arrives already zinc-coated, so the finish can be skipped on outdoor cabinets.
- SPCC cold-rolled steelJIS G31410.4–3.0 mm
- Default for brackets and chassis. Welds clean, takes paint, rusts the moment the finish is skipped.
- SGCC hot-dip galvanized steelJIS G33020.5–3.0 mm
- Zinc survives a sheared edge, so outdoor cabinets can go bare without a paint line.
Specified for conductivity and plating, not for structural strength. C11000 carries current, C26000 forms and takes bright plating.
- C11000 copperASTM B1520.5–3.0 mm
- Busbars and current-carrying parts. Say so if it must be tinned or silver-plated.
- C26000 brassASTM B360.4–2.0 mm
- RF shielding, terminals, decorative trim — it takes bright plating better than steel.
Certificates of conformity travel with the shipment. Name a grade we do not list and we will quote the nearest equivalent we can hold in stock — or tell you plainly that we cannot.
Hold the material before you commit
Photographs flatten a finish and hide a grain direction. We post physical coupons instead: same alloys and tempers as production, labelled with grade and mill standard.
Posted worldwide, free, with the grade and mill standard written on each tag.
Surface finishes for sheet metal parts
Finish is the last decision a buyer makes and the first one that fails in the field. We quote six finishes against the environment the part lives in, not the look book.
Powder coating60–120 μmRAL and Pantone matched, flat to fine texture. The default for outdoor steel.
AnodizingType II / III5–50 μm on aluminium only. Mask the grounding points.
ElectroplatingZn · Ni · Cr · SnZinc first for corrosion, nickel for wear, tin for solderability.
Brushed finish180–600 gritDirectional grain. Grain direction is a drawing callout, not a detail.
SandblastingGlass bead / oxideUniform matte key for paint, or the finished look itself.
Laser engraving0.05 mm depthSerial numbers, wiring labels and QR codes, marked for the life of the part.
Also quoted on request: silk-screen and pad printing, electrophoretic coating, chemical passivation, chromate conversion and post-weld heat treatment.
Colour is the objection we hear most from overseas buyers. It gets the same answer every time: send a RAL or Pantone number plus a photograph of the part under your own lighting, and we spray a panel first and photograph it back before the batch runs.
Fabrication, stamping or CNC — pick by volume
Sheet metal fabrication wins below a few thousand pieces: there is no tooling to pay for. Progressive die stamping wins above it, because the die cost stops dominating and the unit price keeps falling. CNC machining is the third option when a part is thick, three-dimensional or threaded.

What actually moves the price of a sheet metal part
Material and nesting yield
20%extra material cost
Sheet is bought by the sheet, not by the part. A design that nests badly across a 1,220 × 2,440 mm sheet can carry 20% more material cost than the same part nested well, before any machine time is added.
8 proven ways to cut sheet metal costs→Bend count and bend sequence
Every bend is a handling step, and direction matters as much as count. One setup and one gauge change is materially cheaper than three.
Over-specified tolerance
Calling ±0.05 mm on a profile that only needs ±0.2 mm buys inspection time, not machine time. It is the easiest cost to design out.
Surface finish and colour
Powder coating is priced per batch, per colour. Two RAL numbers on one order means two setup cycles — consolidating them is often a five-figure saving across a production year.
Volume and tooling amortisation
Fabrication prices are near-linear in quantity. Stamping prices are not: pass the break-even point and the unit price collapses and stays there.

Fabricated parts ship in 3–7 working days with no tooling cost. Stamped parts go through first-article inspection with CMM data and a dimensional report against your drawing.
Rapid sheet metal prototyping→7 – 15 working days
Production, finish, assemble, ship
One purchase order covers cutting, forming, welding, finishing, hardware insertion, assembly and kitting. Parts leave as a finished unit, not a box of loose components waiting for your line.

How the parts get checked
Incoming material
Thickness, grade and surface condition checked against the mill certificate before the sheet is released to a machine.
In process
First-article check at each workstation — laser, bend, weld, press — then sampling through the run, not just at the end.
Dimensional
CMM and hand gauges against the drawing. Tight-tolerance and stamped parts get a written dimensional report.
Before dispatch
Finish, hardware, labelling and packaging checked, and the batch recorded so a query months later traces back to its run.
WERIX Metal is certified to the ISO 9001 quality management standard. First-article inspection reports, dimensional reports and transit-test results are available for any programme on request.
