BS1387 Galvanized Steel Pipe
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. Made of high-quality Carbon Steel, the tubes are galvanized by applying a zinc coating through a hot dip process to ensure superior corrosion resistance.
BS 1387 pipes are mainly used in construction and engineering projects. The main applications are in piping systems, building structures, general engineering, and more. Available in Nominal Pipe Size Range: DN8 to DN150, with three thicknesses to choose from: light, medium, and heavy.
