BS1387 Galvanized Iron Water Pipes
Galvanized steel pipes have nice performance in anti-corrosion. Gi pipe can be divided into hot galvanized and pre galvanized mainly. Hot galvanized pipe is thick in galvanization layer, so it behaves much well in corrosion resistant. While pre galvanized pipe is much economical. Surface quality of galvanized steel pipe should have a complete galvanized layer, there should be no unplated black spot, there is not much rough surface and the existence.
