ASTM A709 remains the internationally accepted specification for bridge plate steel, offering multiple grades (36, 50, weathering and HPS variants) that balance strength, toughness, and atmospheric resistance. In 2025 market conditions, structural plate supplied to bridge projects shows wide regional price variation driven by scrap/HRC feedstock, tariffs, mill capacity, and logistics — typical delivered plate […]

For procurement of AASHTO M270 structural steel plate in 2025 we find that fair-market delivered prices (standard structural plate, non-coated, typical bridge grades) currently sit in broad regional bands: USA ≈ $850–1,200 / metric ton; China ≈ $420–750 / mt; India ≈ $480–700 / mt; Western Europe / GCC ≈ $700–1,100 / mt. Prices vary

For most heavy-structure applications in 2025, ASTM A871 Grade 60/65 plates give the best combination of high yield strength and atmospheric corrosion resistance at a competitive cost versus specialized weathering steels; however, procurement strategy (region, mill lead-time, heat size and finish) is the single biggest driver of landed price differences worldwide. What ASTM A871 covers

In 2025, ASTM A514 (commonly sold under trade names such as T-1) remains a premium, quenched-and-tempered high-yield structural plate used where strength-to-weight matters. Pricing varies widely by region, order size, grade, and thickness — typical market ranges in mid-2025 for A514 plate are roughly USD $550–$1,500 per metric ton depending on origin and supply chain

For buyers seeking 140 KSI (≈960–965 MPa) ultra-high strength structural plate in 2025, expect a premium over commodity plate: typical commercial ranges sit roughly between ~USD 900 to USD 3,500 per metric tonne depending on brand (e.g., Strenx®/Weldox vs generic Q&T), order size, thickness, and delivery terms.
