3 Celsius 355 NH echnical Guide CELSIUS 355 NH Celsius 355 hot finished hollow section is manufactured exclusively from normalised, fine grain steel for outstanding performance. Where failure is not an option, you can trust Celsius 355 to deliver. Celsius 355 key features: Normalised fine grain steel, so free of internal stresses and 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 circular, square, rectangular and elliptical hollow sections ight corner radii, 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 and, because the steel is fullykilled, excellent weldability Certified as suitable for all structural applications, fully compliant with design codes and overcomes design risks associated with other forms of hollow sectons Certified as suitable for mechanical applications, especially those involving cyclical loading Suitable for low temperature applications -20 C) Batch-tested to give the properties of the specific delivered material; full test certification supplied Clearly marked as Celsius 355, with the reassurance of batch traceability Full technical support available Excellent supply availability through approved stockholders All Celsius 355 material is CE marked and is fully compliant with the Construction Products Regulation Suitable for galvanising 03

4 Celsius 355 NH echnical Guide echnical data ECHNICAL DAA High strength hot finished hollow sections suitable for all construction and mechanical applications. Celsius 355 is suitable for all internal and external applications to BS5950-1:2000, EN1993 and BS5400. Celsius 355 hollow sections are supplied with a minimum yield strength of 355 N/mm 2 and comply fully with the European Standard for hot finished structural hollow sections, EN10210: S355NH.
