EN Standard S355 Structural Steel Plate
S355 structural steel plate is a higher-yield steel plate than EN S275, making it a popular choice for structural fabrication.
Overview:
- High-strength non-alloy structural steel used in a variety of structural fabrication applications including bridge components, components for offshore structures, power plants, mining & earth-moving equipment, load-handling equipment, and wind tower components.
- Meets European structural steel standard EN 10025:2004.
- Similar to ASTM A572 and ASTM A709 steel grades.
- Material properties and chemical compositions vary by qualities (i.e. JR, JO, K2) as specified by EN 10025 grade specifications.
- Due to quickly shifting inventory with this grade of structural steel, please inquire about available sizes.
- Careful attention should be placed on the specific variation of S355 required if considering substitute material.
S355 Equivalent Plate Grade
The chemical composition and mechanical properties of S355 are governed by EN Standards However, some projects may require materials that meet ASTM standards. ASTM has identified A572-50 as an acceptable substitution for S355. Both grades have similar chemical compositions and are high-strength, low-alloy structural steels.
Industries and Applications
S355 plate is used in specific projects that are based on European design and require materials that meet European standards. While this can include various industries, it is typically used in wind energy applications with the U.S.
