为提高钢管的耐腐蚀性能，对一般钢管进行镀锌。镀锌钢管分热镀锌和电镀锌两种，热镀锌镀锌层厚，电镀锌成本低，表面不是很光滑。吹氧焊管：用作炼钢吹氧用管，一般用小口径的焊接钢管，规格由3/8-2寸八种。用08、10、15、20或者195-Q235的钢带制作成的，为了防腐蚀，有的要进行有效渗铝处理。

老房子大部分是用的都是镀锌管，现在煤气、暖气用的那种铁管也是镀锌管，镀锌管作为水管，使用几年后，管内产生大量锈垢，流出的黄水不仅污染洁具，而且夹杂着不光滑内壁滋生的细菌，锈蚀造成水中重金属含量过高，严重危害人体的健康。六七十年代，国际上发达国家开始开发新型管材，并陆续禁用镀锌管。中国建设部等四部委也发文明确从二000年起禁用镀锌管，目前新建小区的冷水管已经很少使用镀锌管了，有些小区的热水管使用的是镀锌管。^[1]
