Reference information
Commonly cited families (verify edition on your certificate):
- EN 10060
- ASTM A29/A108
- GOST 2590
- GOST 7417
Round bars and rods reference EN 10060, ASTM A29 / A108 (machining grades), and GOST 2590 / 7417 depending on market. Cold-drawn vs hot-rolled tolerances change the effective diameter used in precise mass checks.

How to calculate weight
Core model
V = π · (d/2)² · L
m = ρ · VField names
A round bar is a solid round: volume = πr²L, mass = volume × density. This matches round bar weight calculator and solid shaft weight searches.
