Processing

S355JR / J0 / J2 I-beams, structural engineering is used in the beams or columns, known as the word iron, according to Euler-Bernoulli beam theory (Euler-Bernoulli beam theory), this structure resistant to bending and shear stiffness is very strong, but the torsional stiffness is poor.

Current S355JR / J0 / J2 I-beam are mainly two. One is crimped steel there is a flat beam. Crimped steel can be used to cool or heat curly, curly to get squeezed. The plane beam welding or cement may be used to obtain coverage.

S355JR / J0 / J2 I-beam is widely used in the construction industry. Available platform provides a selection of appropriate steel. S355JR / J0 / J2 I-beam can be used as a column, it can also be used as a beam. Railway tracks with similar shape I-beam.
