What is a galvanized welded steel pipe?
Galvanized welded steel pipe is a material that has good corrosion resistance and little rust, so it is widely used in everyday life. Let’s find out what galvanized welded steel pipes are. And where should I buy this type of steel pipe to ensure quality?

What is a galvanized welded steel pipe? Characteristics and structure
Galvanized welded steel pipes are created through the galvanizing process for welded steel pipes. To get welded steel pipes, we will roll steel sheets and weld them together. Then galvanizing will be carried out by hot dipping or electrolysis to get the final product.
When welding steel plates, two methods will be used: straight welding and spiral welding. Spiral-welded steel pipes are often quite large, so they are often painted with anti-rust paint. In contrast, straight-welded steel pipes come in a variety of sizes. At the same time, it has higher aesthetics, so it can be used in more applications.
