Product Description
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
