The reliability of quality assurance was undermined because the bridge and building were constructed with products that have “rust” after joining the bolts at the sites. Moreover some bolts used at several sites were stored outdoors for storge, or in extreme conditions, instead of room temperature as required in the specifications. So, it was necessary to analyze how the surface treatment that enhanced corrosion-resistance affected the high strength bolts, nuts and washers. This test focuses on the correlations between the coating thickness after surface treatments and the corrosion resistance of the surface treatments (Geomet, Dacro, Green Kote, Armor Galv.). The quality characteristics of the corrosion resistance required by the KS D9502 standards were discussed. Surface treatments were implemented on the S10T sets of bolts under the same environmental factors. All corrosion resistance after surface treatments meets the criterion required by the specifications. Although the coating thickness after surface treatment should be considered as its own characteristic of the surface treatment process, Armor Galv. was the highest at 52.7 ㎛ ~ 57.6 ㎛ and Dacro was the lowest at 10.6 ㎛ ~ 12.1 ㎛. The coating thickness after surface treatment did not affect the corrosion resistance of these high strength bolts.
