Black steel inspection: inspection prior to hot dip galvanizing is extremely important.
Blowouts: Staining and coating defects around unsealed weld areas and vent holes. Similar to stains ceased by weeping. This is caused by pre-treatment chemicals penetrating sealed overlap areas through the required vent holes and escaping during immersion in the molten zinc. This effect tends to damage the flux coating, causing localised uncoated areas.

黑钢视察:检查之前，热镀锌是极其重要的。
井喷：染色和涂层缺陷焊缝周围地区启封和通风孔。类似的污渍停止哭泣.这是造成前处理化学品的穿透密封的重叠领域需要通过通风孔和逃避沉浸在钢水中的锌。这种影响往往会损害通量涂层，未造成局部地区。
给多点分嘛，而且你的分类也不对，这里是历史学主题
