EN 10060 (Tolerancies)

Allowances hereunder indicated are valid for length under 1000 mm, for upper lengths you need to consider also the straightness deviation according to norms.

Example: for finished round 75 mm, you have to order 79 mm. If this size is not in the normal range of production, you’ll have to order an 80 mm bar

> 250 ± 6,0 Lucefin Group, as for what concerns the bars assigned to peeling, requires a maximum deviation on straightness of 2% uniformly along the total length.
The deviation for roundness shall not exceed 75% of the tolerance range
