HEM200 S355JR S355J2 h beam steel structure
S355JR h section steel beam: If the project is located in a relatively mild area or the requirements for low-temperature environments are not high, the use of S355JR can meet the needs of most general buildings and structural engineering.
S355J2 h shaped beam: For projects that need to maintain good toughness in low-temperature environments, such as buildings, bridge construction in cold climates, or any structure that may be affected by low temperatures, S355J2 is a better choice.
