Strcuture
The structural system behind B.E.S.D.® technology employs standard steel profiles, such as HE, IPE, UPN, commercial and flat C-profiles. Their thickness is never below 4 mm
Material S355 JR electro-welded commercial steel Finishes ■ cold galvanising ■ epoxy resin based paint ■ intumescent painting ■ powder coating ■ anti-rust treatments Connections All connections undertaken on-site require the use of bolts, nuts and washers having a strength class of 8.8 and/or 10.9 (high strength). All welding operations are carried out in the workshop and are completed in compliance with the UNI EN ISO 3834 standard, including all subsequent integrations, and UNI 5132: 1974.
