Quality manufacturer Zizi offers Galvanized Carbon Steel Forged Pipe Fittings 1 / 8 " to 4 " ASME B16.11 with various dimensions and best price.
As we all know, the durability of carbon steel pipe fitting is inferior to that of stainless steel pipe fittings, but the price of stainless steel is higher than carbon steel. SO from the cost perspective, it is better to use carbon steel pipe fittings with galvanized coating. For forged steel fittings, the most common used coating are hot galvanizing and cold galvanizing. And here are more choose for butt weld fittings such as PE coating and black primer.
