BS1387 Galvanized Steel Pipe
BS 1387 is a British standard. It specifies requirements for galvanized steel pipes. These pipes are used mainly in construction and engineering.
Carbon steel. Steel is galvanized by applying a zinc coating through a hot dip process.
BS 1387 pipes are mainly used in construction and engineering projects. The main applications are in piping systems, building structures, general engineering, etc.
Nominal Pipe Size Range: DN8 to DN150, with three thicknesses to choose from: thin, medium and thick.
