SCH10 SCH30 Galvanized Steel Pipe Q345A 10# 20# Welded Round Tube
for Construction
Galvanized welded steel pipe, also known as welded pipe, is a steel
pipe made of steel plate or strip steel after crimping and welding,
and the length is generally 6 meters. Welded steel pipes have
simple production process, high production efficiency, many
varieties and specifications, and less equipment investment, but
the general strength is lower than that of seamless steel pipes.
