Weekly Price Signal
China steel spot prices showed a coordinated compression across flat and long product categories during the week ending 2026-09-11, with the majority of benchmark products trading lower against the prior five-day average.
Hot Rolled Coil (HRC), the broadest demand proxy, settled at USD 542.51/ton FOB Shanghai on Friday, down -0.28% from the previous session and -USD 3/ton (-0.6%) versus the prior week average (USD 533/t vs. USD 536/t implied baseline). Daily volatility ranged from USD 520 to USD 534, reflecting an intraweek dip early in the period. The 20-day range for HRC spanned USD 520–534, indicating tight consolidation without directional breakout.
Medium Plate contracted more sharply at -0.50% to USD 609.39/ton FOB, with the weekly average landing at USD 601/t (-USD 3, -0.5%). The daily sequence moved from USD 583 on Monday to USD 551 by Wednesday before recovering to USD 581 by Friday — a classic mid-week correction pattern. This product remains the steepest decliner among the four core categories tracked.
Cold Rolled Coil (CRC) held relatively steadier at USD 603.45/ton FOB, declining only -0.28% on the week, with the weekly average at USD 592/t (-USD 2, -0.3%). The 20-day range narrowed to USD 584–654, suggesting value-added demand is absorbing cost pressures without immediate pass-through.
In long products, structural steels mirrored the flat-gauge weakness: Angle Steel at USD 533.59/ton FOB (-0.28%), Channel Steel at USD 536.56/ton FOB (-0.28%), and I-Beam at USD 558.86/ton FOB (-0.27%). Weekly averages placed Angle at USD 525/t (-USD 3), Channel at USD 528/t (-USD 3), and I-Beam at USD 548/t (-USD 2). Rebar (φ10/HRB400) was the sole bright spot among rebar products, gaining +0.4% weekly to USD 554.40/ton FOB, supported by a Monday spike to USD 560/t.
High Speed Wire Rod remained flat at USD 573.72/ton FOB (weekly avg: USD 562/t, +USD 0). Pre-stressed steel wire (82B) advanced +0.80% to USD 943.81/ton FOB — the strongest performer of the week — while boiler and pressure vessel plate (Q345R) held at USD 677.76/ton FOB flat.
The DSP Composite Index (last published 2026-09-04, value 991.55) is currently stale as of 2026-09-04 and should not be treated as a live signal. The CNY/USD rate stands at 6.728034.

Cross-Border Grade Equivalence
Procurement teams sourcing China-origin steel for ASTM or EN specification projects should map the following equivalences to avoid specification misalignment at customs and mill certification stages:
- GB Q235B ≈ ASTM A36 (structural plate & HRC) — the dominant grade for general construction and machinery frames. Widely accepted under both standards for non-critical load-bearing applications. - GB SS400 ≈ JIS G3101 SS400 (HRC) — the Japanese-equivalent counterpart commonly specified in APAC EPC projects. - GB ST12 / DC01 ≈ EN 10130 DC01 (CRC) — cold-rolled deep-draw quality. Confirm formability requirements exceed EN minimums before substituting Chinese-origin coils. - GB Q345R ≈ ASTM A516 Gr.70 (plate) — the primary equivalence for boiler and pressure vessel applications. This grade trades at USD 677.76/t FOB and requires mill test certificates aligned to EN 10204 Type 3.1. - GB HRB400 ≈ ASTM A615 Gr.60 (rebar) — the standard reinforcement grade for seismic and structural concrete work.
When switching between GB-sourced material and ASTM/EN-mandated specifications, validate yield strength and chemical composition tolerances against the project's ITP (Inspection and Test Plan). Misclassification at the Bill of Lading stage can trigger demurrage or re-inspection costs.
Procurement Action
Flat-Gauge Buyers (HRC / CRC / Plate): The current environment favours a cautious stance. HRC at USD 542.51 and medium plate at USD 609.39 represent the lower bounds of their respective 20-day ranges. A Medium Plate Strong Buy Window is open for buyers requiring 8mm+ thickness — the -0.50% weekly compression is the most acute discount across all categories. Use Landed Cost Calculator to model landed cost under current freight conditions.
Long-Product Buyers (Rebar / Beam / Channel / Angle): Structural steel weakness is broad-based but shallow. Rebar's +0.4% weekly gain suggests residual demand support in the building sector. Hold & Monitor is the recommended posture for angle, channel, and I-beam — no compelling entry signal exists yet. Use RFQ Gateway to secure competitive bids for Q4 delivery windows.
Industrial / Specialty Buyers (Pre-stressed Wire / Boiler Plate): Pre-stressed 82B wire at USD 943.81 (+0.80%) is the clear outperformer and warrants immediate action. Lock in freight rates and forward bookings to avoid further premium erosion. Boiler plate (Q345R) remains flat at USD 677.76 — a stable entry point for pressure vessel spec work.
Overall weekly positioning: moderate discount environment with no sustained trend. Prioritise medium plate buys and pre-stressed wire forward contracts; hold flat on HRC and CRC until next week's volume data arrives.
