Visual Guide to Inspecting
Hot-Dip Galvanized Coatings on Reinforcing
Steel
A
visual inspection should be performed at the
galvanizer’s facility to ensure compliance
with the coating specification. Varying appearances
may occur and may or may not affect the overall
quality of the product. A simple visual
inspection can assure that the galvanized
coating is incompliance with the proper specifications.

Another important aspect of inspection is
ensuring that the coating thickness complies
with the appropriate specification.
The thickness of the coating directly
relates to the life of the rebar.
Therefore inspecting the coating thickness
is an important component to the overall
inspection process. The inspection
process at the galvanizing plant includes a
step where the coating thickness is verified
to meet the appropriate specification.
However, to ensure compliance, the
galvanized coating thickness can be easily
measured using a simple device. Click the
