Production technical conditions of all rolled products are in accordance with EN, or other world standards, or as required by customers.

- Mechanical properties (all tempers) such as conductivity, grain size, etc. are in accordance with EN, other world standards, or as required by customers.

- Surface qulity, flatness, edgewise curvature and other requirements are in accordance with EN, other world standards, or as required by customers.

- Brass roundels are shipped only in hard temper.

Size tolerances of all rolled products are in accordane with EN, other world standards, or adjusted to customers requirements.

The following table shows first level reduced tolerances on thickness in relation to EN 1652 standard, depending on thickness and width of rolled products. For listed thicknesses and those (over) > 3,2 mm strips are produced with tolerances as per standard, or reduced as per customers requirements.
