Design Criteria

Our calculations meet the newest standard EUROCODE and are recognized by international inspection offices. The EUROCODE replaces the former national standards (French NFP, German DIN etc.) which are no longer valid. Where EUROCODE is specified, a separate calculation for each project based on the common texts and the national annexes is compulsory and is calculated according to the nature of the stored products, the earthquake (seismic) (EN 1998-4 + NA), wind (EN 1991-1-4 + NA) and snow (EN 1991-1-3 + NA ) conditions applicable to the specific area.
