Quality and sustainability

Solid Group Metal produces under an ISO 9001 quality management system. The applicable tolerance standard (for example EN 755-9 or EN 12020-2) and the numerical values for the critical dimensions on your drawing are agreed in the quotation.

Inspection points

  1. DrawingCritical dimensions are jointly marked on the drawing.

  2. SampleThe first-off part is compared against the drawing; series production proceeds according to the approved sample.

  3. Dimensions and surfaceRequirements are written into the order.

Which quality system do you work under?

Production runs under an ISO 9001 quality management system. For you this means dimensional and surface requirements are written into the order, and sample approval and series production are tied to the same requirements.

Which standards are relevant?

Standard Scope
EN 755-9 Dimensional and form tolerances of extruded profiles
EN 12020-2 Dimensional and form tolerances for precision profiles in EN AW-6060 and EN AW-6063
EN 573-3 Chemical composition of alloys
EN 755-2 Mechanical properties of extruded products

These standards are listed as references. The applicable tolerance standard and class are agreed in the quotation. Where the standard has no equivalent for a dimension, a numerical tolerance is agreed at quotation together with the critical dimensions on your drawing.

How are dimensions and surface verified on your part?

At sample approval you compare the first part against the drawing, and series production follows that approved sample. We mark with you which dimensions are critical and how they will be verified. The process is described under Custom aluminium extrusion.

Why is aluminium a sustainable material?

Aluminium can be recycled repeatedly without losing its properties, and extrusion offcuts and swarf remain usable as the same material. We do not publish company-specific recycling rates or energy figures until they are verified.

For the production base see Facility and capacity; for end uses, Industries.

Frequently asked questions
