Inspection and Testing for Hot Finished EN10210 S355J2H

Hot finished structural hollow sections are submitted to specific inspection and testing, and supplied with an inspection certificate to EN 10204 type 3.1.

Designation for Hot Finished EN10210 S355J2H

Hot finished structural hollow sections are designated by their material grade, external dimensions and thickness in millimeters.

EN10210 S355J2H key features:

• Hot finished, free from internal stresses and Vitiligo with a minimum strength of 355 MPa – allowing the highest fabrication factors and enabling material cost savings and lighter structures

• Available in a wide range of shapes such as circular (CHS), square (SHS), rectangular (RHS), elliptical, half-elliptical, flat-oval, octagonal, hexagonal, triangular and other profile hollow sections

• Tight corner radius, exceeding the standard - enhancing the product’s aesthetic appeal whilst avoiding the risk of brittle fracture which occurs in some cold formed products

• Dimensional consistency, high levels of formability because the steel is fully-killed with excellent weldability

• Certified as suitable for all structural applications, fully compliant with design codes and overcomes design risks associated with cold formed products

• Certified as suitable for mechanical applications, especially those involving cyclical loading

• Suitable for low temperature applications (-20°C)

• Batch-tested to prove the properties of the specific delivered material; full test certification supplied

• Clearly marked as S355J2H with the reassurance of batch traceability

• Full technical support available

• Also available to be certified as normalized fine grain S355 NH condition

• S355J2H RHS, SHS, CHS, Elliptical, Half-Elliptical, Flat-Oval, Octagonal, Hexagonal, Triangular and other profile Hollow Sections are CE marked and fully compliant to the Construction Products Directive

• Suitable for galvanizing
