Note - As agreed between the manufacturer and the customer for steel from steel grades 25, 30, 35, 40, allowed reduction of tensile strength of 20 N/mm, compared with the standards set out in the table, while improving the rules elongation of 2% (abs ).
In bundles, weight 5 tons max., with banding by wire rod 6,5 mm in 6 places min. equally distributed over bundle. Each bundle is provided with 2 steel straps for multiple lifting.
