Custom Cut High-Strength AS/NZS3678-350 Steel Plates for Heavy Infrastructure Fabrication Projects

We provide Custom Cut High-Strength AS/NZS3678-350 Steel Plates specifically for heavy infrastructure fabrication projects. These plates are produced from AS/NZS3678-350 certified steel with a minimum yield strength of 350 MPa, delivering high load capacity, excellent weldability, and consistent performance under heavy structural demands. We support custom cutting, drilling, beveling, surface treatment, and export packing, ensuring each plate arrives ready for bridge girders, heavy columns, connection plates, bracing systems, and other critical steel components.

Why AS/NZS3678-350 Is the Right Grade for Heavy Infrastructure​

• • Certified Strength: AS/NZS3678-350 provides a minimum yield strength of 350 MPa, suitable for heavy load-bearing structures.

• • Weldability: The chemistry and rolling process support reliable welding in fabrication workshops.

• • Toughness: Designed to resist impact and fatigue in bridge, industrial, and infrastructure applications.

• • Traceability: Every plate is backed by a mill certificate for full material traceability.

• • Consistency: Controlled rolling ensures uniform mechanical properties across the plate.

Custom Cutting: Precision from Drawing to Finished Plate​​

• • Drawing Review: We review your CAD drawings, connection details, and tolerance requirements before cutting.

• • Cutting Methods: Plasma cutting, flame cutting, and saw cutting are available for different thicknesses and shapes.

• • CNC Drilling: Accurate hole patterns for bolted connections and assembly.

• • Edge Preparation: Beveling and machining for welded joints and fit-up.

• • Dimensional Control: Length, width, diagonal, and flatness are checked after cutting.

High-Strength Performance in Demanding Fabrication​​

• • Heavy Load Capacity: Suitable for bridge girders, transfer beams, and heavy support frames.

• • Fatigue Resistance: Helps structures withstand cyclic loading in bridge and infrastructure projects.

• • Stable Strength: 350 MPa yield provides reliable performance under heavy static and dynamic loads.

• • Fabrication Friendly: Plates can be welded, drilled, machined, and coated as required.

• • Long Service Life: Combined with surface protection, plates resist corrosion and wear.
