EN10210 Hot Finished Structural Hollow Section Pipes

Introduction

EN10210 standard covers multiple shapes of hollow section pipes, such as circular, square, rectangular, and elliptical forms. EN10210 standard covers multiple high strength steel grades: S235JRH, S275J0H, S275J2H, S355J0H, and S355J2H. The number represents their minimum yield strength; The suffix letters represents their impact performance under different temperatures. These steel grades have high strength, good plasticity and welding performance. Due to their special shapes, EN10210 square and rectangular pipe is not prone to deformation when suffering from large external forces. It is commonly used in the field of steel structure, such as building, support structure, and bridge engineering, etc.

Square and rectangular pipes are available in various sizes, other non-standard dimensions of square and rectangular pipes also can be offered.
