Bolt Specification for Exterior Application
Bolt Specification for Exterior Application
(OP)
What finish specification should be used for exterior application of ASTM A307, A325 and A490 structural bolts and ASTM A36 and A307 threaded rod? Zinc? Galvanized?
In what application would I specify ASTM A572, A588, A449 threaded fasteners or rods?
Thank you!

RE: Bolt Specification for Exterior Application
For anchor rods the most accepted standard is the ASTM F1554 rod. This can be specified in 36, 50, and I believe 70 ksi applications. It can be galvanized, and it has good ductility properties.
