Abstract

본 발명은 건축구조물의 외장재, 계단받침대 및 아파트 바란다용 등에 사용되는 스테인레스강관의 표면처리 방법에 관한 것이다.
본 발명은 조관후 스테인레스 강관을 표면처리하는 방법에 있어서, 표면연마시 10-50%의 질산함유 수용액으로 분사세척한 다음, 물로서 세척하여 중화시키거나 또는 표면연마시 10-50%의 질산함유 수용액으로 분사 세척하고; 그리고 바흐연마시 10-50%의 질산함유수용액으로 분사세척한 다음 물로써 세척하여 중화시킴으로써, 내수성을 향상시킬 수 있는 스테인레스 강관의 표면처리 방법을 그 요지로 한다.
