S355 Standards / Specification

Product category:

  • Universal Beam / Column
  • Hollow section
  • Sheet / Plate
  • PFC
  • Angle
  • Flat
  • Round
  • Square.

Product standards:

  • EN 10025
  • EN 10219

Description:

S355 is a low carbon, hot rolled structural steel, extensively used in the production of hot rolled universal beam, column and other long products. Chemical and mechanical levels are ideal for machining and forming.

Hot rolled products are easily galvanised but some products may distort. Larger hollow sections with a greater wall thickness are more readily available in S355 than the lower tensile S235. Smaller long products are available to mill rolling.
