Technical Specifications Of DN100 BS1387 ERW Galvanized Steel Pipes

BS 1387 pipes are typically manufactured from mild carbon steel with mechanical properties comparable to S195 or S235 grades, providing a minimum yield strength of approximately 195–235 MPa and tensile strength ranging from about 320 to 510 MPa. The chemical composition generally limits carbon to around 0.20 percent, ensuring good ductility and weldability, which is essential for fabrication and assembly in construction environments. These properties allow the pipe to perform reliably under moderate loads and repetitive use in scaffolding systems.

Huayang Steel Pipe produces DN100 ERW pipes using advanced high-frequency electric resistance welding technology, ensuring a uniform longitudinal weld seam with stable quality. The pipes are then processed through hot-dip galvanizing, forming a zinc coating typically ranging from 60 to 85 microns, which provides effective protection against atmospheric corrosion. Each pipe undergoes coating thickness inspection, adhesion testing, and dimensional verification. This combination of base material strength and durable galvanizing ensures long service life and consistent performance in construction and scaffolding applications.
