16Mn I-Section Steel is a hot-rolled low-alloy high-strength I-beam meeting Chinese national standards, equivalent to Q345 grade, a mainstream heavy load-bearing structural profile. It features outstanding tensile strength, excellent low-temperature toughness and superior weldability, with precise dimensional tolerance and remarkable bending & shear resistance for medium to heavy load-bearing scenarios. Easy for on-site cutting, drilling and forming, it can be galvanized for enhanced corrosion protection as required. Full in specifications, cost-effective and durable, it’s ideal for large construction, industrial and bridge engineering projects.
