Product Detail
S235 galvanized steel pipe is a reliable choice for construction and industrial applications. The “S235” grade signifies a solid minimum yield strength of 235 MPa, providing ample durability for structural needs.
Its galvanized coating helps resist corrosion, so it stands up well to rust in outdoor and humid environments. This makes it a good fit for applications like scaffolding, bridge supports, and general construction frameworks.
This pipe is also straightforward to work with—suitable for cutting, welding, and other processing methods—so it’s versatile across various projects. While it’s more economical than higher-strength steels, the galvanized layer’s lifespan can vary by environment, so periodic maintenance might be useful in harsher conditions.
