## Capability — approved figures, each with its stated limit

These are review and selection figures, not blanket guarantees. **Do not combine them into a
single "0.6–200 mm sheet metal" range**: cutting, bending, welding, machining and assembly
describe different constraints.

- **Sheet metal, typical fabrication range:** 0.6–5 mm. A typical range, not a universal machine limit.
- **Bending, thickness:** commonly 0.6–3.5 mm.
- **Bending, length:** press-brake machine envelope up to 3,200 mm. Fabex normally prefers continuous bends at or below approximately 2,000 mm; bends longer than that require drawing review.
- **Laser cutting:** steel and other supported metals below 20 mm. Maximum thickness is material- and grade-specific.
- **Welding:** plate around 10 mm and above can be welded.
- **CNC machining:** material or part sections up to approximately 200 mm can be reviewed. This is machining capacity, not sheet-metal thickness.
- **Single fabricated part, review envelope:** up to 5 m long × 3 m wide × 3 m high. Most shipping pieces should target approximately 2.3 m or less for container and truck compatibility.
- **Standard stock:** 2440 × 1220 mm sheet should be considered during layout and nesting.

## Indicative tolerances — not blanket guarantees

- Suitable CNC-machined features: approximately ±0.05 to ±0.10 mm may be achievable.
- Laser-cut features: approximately ±0.2 to ±0.5 mm.
- Fabricated assembly interfaces: often ±0.5 to ±1.0 mm.

Process, material, thickness, feature and part size, datums, setup, bends, welding, coating,
functional fit and inspection method govern the released tolerance. Released tolerances are
stated in the quotation for the approved scope.

## Materials

SPCC, SGCC, SECC, aluminium 5052, SUS304, and other drawing-specified grades.

## Operations

Cutting, punching, bending, welding, hardware insertion, finishing, assembly, and CNC
machining review — reviewed together under one revision and inspection plan.

Finishing: in-house automated powder coating for light parts and a wet-paint shop for large or
heavy fabrications (typical powder build 60–120 µm, specification-dependent). Coordinated
specialist processes include hot-dip galvanizing, electro-galvanizing, anodizing, passivation,
PVD and plating.

## Certifications

Held, and publishable:

- **ISO 9001:2015** quality management system (GB/T 19001-2016)
- **ISO 14001** environmental management
- **ISO 45001** occupational health and safety management

Certificate numbers, legal entity, scope, certification body and issue or expiry dates are not
published. Request the current certificate for verification.

**Not held, and deliberately never claimed:** IATF 16949, CE marking, UL listing, RoHS
conformity, REACH conformity. Fabex does not offer these. Fabricated sheet metal parts are
**components, not finished products placed on the market**, so CE and RoHS conformity is the
buyer's product-level obligation — a buyer who needs it commissions testing themselves,
directly or through a third party. Do not describe Fabex as CE-certified, RoHS-compliant,
RoHS-ready, or "tested to RoHS".

## How to engage

Send CAD or drawings, material, quantity, finish, critical requirements, and the delivery
destination. US-specific or market-specific requirements should be stated with the drawing.

- **Engineering reply:** within 4 business hours
- **Quotation:** within 24 hours
- **Prototypes:** from one piece
- **Production orders:** subject to a minimum order quantity, confirmed in the quotation against the part and annual demand
- **Manufacturing lead time and freight:** quoted separately from the part price, so landed cost can be compared
- **Material documentation:** material certificates or datasheets from Fabex's material suppliers, on request. They do not accompany every order as standard.
- **Inspection:** an agreed inspection plan per order; project-specific records such as dimensional reports, first-article records, material certificates, coating-thickness results and weld or finish inspection can be provided when requested and included in the agreed scope

## Confidentiality

NDAs are accepted. Drawings are used only to review and manufacture the order. Customer names,
drawings and project details are not published without written permission.

## What Fabex is not

- Not a retail, repair or walk-in fabrication shop — it serves OEM and contract-manufacturing programs.
- Does not provide CE or RoHS conformity testing, marking or certification.
- Does not publish a pieces-per-month capacity figure; capacity is planned from the specific workload.
