S275 galvanized pipe uses European standard EN 10219 S275J0H/S275J2H structural steel as the base material and is treated by hot-dip galvanizing process. Its yield strength is ≥275MPa, tensile strength is 410-560MPa, and its mechanical properties are better than S235 series. It is widely used in places with high load-bearing requirements such as building steel structures, engineering machinery, bridge supports, etc. The galvanized layer provides more than 20 years of anti-corrosion protection, and is particularly suitable for outdoor and harsh environments.
