Productbeschrijving

Durable Construction Carbon Steel Plate — Q345B High Strength Structural

Our Q345B durable construction carbon steel plate is engineered for long-service-life building and infrastructure projects. With 345 MPa minimum yield strength — 38% higher than standard structural steel — these plates enable lighter, more efficient building designs. Normalized delivery provides uniform microstructure and guaranteed impact toughness. Specified by leading engineering firms for commercial high-rises, long-span bridges, and stadiums across the Middle East, Southeast Asia, and Africa.

Key Features

  • Enhanced Durability: Normalized for uniform grain structure and superior toughness over the structure's entire design life
  • 38% Stronger: 345 MPa yield reduces foundation loads and total steel tonnage by up to 25%
  • Weather Resistant: Optional copper-chromium microalloying provides 2-4x atmospheric corrosion resistance
  • CE Marked: Full CE marking with Declaration of Performance for EU-funded projects worldwide

Technical Specifications

GradeQ345B / S355JR / A572 Gr50
Thickness4mm - 100mm
Width1500mm - 3500mm
Yield≥345 MPa (≤16mm)

Applications

  • Middle East: High-rise cores, stadium roof trusses, airport structural steel
  • Southeast Asia: Bridge girders, industrial plant steelwork
  • Africa: Stadium grandstands, mining plant structures
