ASTM A53 BS 1387 Threaded Both Ends Black Iron Conduit Galvanized Steel Pipe

ASTM A53 BS 1387 Threaded Both Ends Black Iron Conduit Galvanized Steel Pipe. Hot-dip galvanizing forms an even zinc layer on the surface, offering reliable anti-rust and anti-corrosion performance for long-term outdoor use. The zinc coating closely bonds with the steel substrate, not easy to peel off during cutting, bending and on-site installation. Made of Q235B carbon steel, the pipe owns good rigidity and load-bearing capacity, suitable for scaffolding, pipeline and frame projects. Zinc coating will not fall off easily during secondary processing such as cutting and bending, convenient for field construction.
