What are the standards for pre and post galvanizing?
In addition to the governing standards, there are a handful of pre- and post-galvanizing supporting specifications that a specifier/designer should also be familiar with: ASTM A143/A143M: Standard Practice for Safeguarding Against Embrittlement of Hot-Dip Galvanized Structural Steel Products and Procedure for Detecting Embrittlement
What is the code for galvanizing structural steel?
The code designation for galvanizing is “V”. If painting of the structural steel is not specified then the word “PAINTED” may be omitted, the month and year shall then correspond to the date the stencil is applied.
How much galvanizing is needed on a girder?
At field splices of beams or girders, galvanizing exceeding 0.08 in. (2 mm) on the cross-sectional (end) face shall be partially removed until it is 0.04 in. to 0.08 in. (1 to 2 mm) thick. Testing of Hot Dip Galvanized Coating.
When do galvanized steel surfaces need to be repaired?
Surfaces of galvanized steel that are damaged after the galvanizing operation shall be repaired according to ASTM A 780 whenever damage exceeds 3/16 in. (5 mm) in width and/or 4 in. (100 mm) in length. Damage that occurs in the shop shall be repaired in the shop. Damage that occurs during transport or in the field shall be repaired in the field.
