Quality you can audit, not just admire
An EN 9100 aerospace-grade management system, ISO-certified operations since 1992, and a metrology lab that measures down to a quarter of a micron — with a quality certificate accompanying every shipment.
Certificates
Aerospace-grade, third-party verified
Certification isn't a logo on a slide — it's an audit trail. Here is exactly who certified what, and until when.
EN 9100:2018 — Aerospace QMS
Quality management system for the production of cast slabs and billets, extruded bars and profile shapes, and mechanical components. Technically equivalent to AS9100D and JIS Q 9100:2016; audited per EN 9104-001.
ISO management systems
Three decades of continuously maintained management-system certification across quality, environment, and occupational health & safety.
Metrology Laboratory
Measured to 0.25 µm. Documented to the heat.
Every claim on a certificate is backed by an instrument on this list.
| Instrument | What it verifies |
|---|---|
| Optical emission spectrometer (M10) | Chemical composition of every heat |
| Universal mechanical testing machines | Tensile and yield strength, elongation, hardness |
| Metallographic microscope | Micro- and macro-structure evaluation |
| Digital calipers (0.01 mm) | Tight-tolerance dimensional checks |
| Dial & vernier calipers (0.02 mm) | Conventional dimensional measurement |
| Height gauges | Rod and tube diameters |
| Plug gauges | Flatness, straightness, linearity, perpendicularity |
| Ring & pin gauges | Bore verification on larger holes |
| 2D vision measuring system | Non-contact geometry — fields of view from 0.8 × 0.6 mm to 225 × 190 mm, length error down to 0.25 µm |
| 3D Vision H500 coordinate system | Geometric and positional tolerances, twist and bend testing, complex surfaces — computer-processed against 3D drawings |
Extended group laboratory: scanning electron microscopy (SEM), deep-drawing testing and metallographic research for rolled products.
