1There is possibility to deliver in coils or bars upon agreement with production plant.
Notice:
The limit deviations of rib height h are: - to 16 mm + 40 %, - 25 % of mentioned value of size- from 18 mm 25 % of mentioned value of size
Allowed deviations of ribs pitch L are 15 % in all extent of mentioned diameters.
The diameter o f cover area is measured over longitudinal ribs
