中国钢材周报：螺纹钢与热轧板卷领涨，长材平稳 — 2026年9月4日

Weekly Price Signal

China steel weekly report data for the period ending 2026-09-04 shows a market holding steady with selective strength across four major product segments. The DSP Composite Index registered at 991.55, up 0.14% day-over-day, reflecting a consolidating posture following the volatile mid-August swing.

Rebar leads the week with a weekly average of USD 538/t versus USD 540/t this period — a net gain of +USD 2/t (+0.4%). The current spot price for φ10 HRB400 rebar stands at FOB $552.89/t (+0.28%), while high-speed wire rod (φ6 Q235) sits at $573.70/t (+0.27%). Spiral rebar (φ6 HRB400) adds further strength at $604.91/t (+0.25%). All three building rebar grades moved in unison, signaling coordinated mill support rather than spot-driven pressure.

Hot Rolled Coil (HRC) and Cold Rolled Coil (CRC) show flat weekly performance. HRC weekly average landed at USD 530/t (−USD 2/t, −0.4%), while current spot price for 2.75mm Q235B/SS400 is $546.95/t (+0.28%). CRC weekly average remained unchanged at USD 589/t, with the current spot at $606.40/t (0.00%). The CRC-HRC spread widened to $59.45/t, reflecting ongoing preference for downstream manufacturing demand over base coil buying.

Medium Plate traded range-bound: weekly average of USD 598/t (flat versus prior), with current 8mm Q235B spot at $613.83/t (−0.25%). Low-alloy plate (Q355B) dipped −0.25% to $604.91/t, and cold-forming coil (TECC) fell −0.26% to $587.08/t. Ship plate (CCSAH36) was the standout industrial grade at $622.75/t (+0.49%).

Long products — angle steel, channel steel, and I-beam — all posted weekly averages of USD 522/t, USD 525/t, and USD 544/t respectively, each down USD 2/t (−0.4%) from the prior week. Current spot prices held flat: angle $538.03/t, channel $541/t, I-beam $560.32/t. This uniform flatness across section steel points to stable mill pricing with no active discounting.

The USD/CNY exchange rate remains at 6.7787 (as of 2026-09-04), providing a stable conversion baseline for FOB pricing. Freight conditions are mixed: Asia-internal routes are stable, European and North Atlantic lanes remain range-bound, and Middle East routes softened slightly.

Cross-Border Grade Equivalence

International procurement teams frequently encounter grade-mapping gaps when switching between GB standards and ASTM/EN specifications. The following equivalences are critical for this week's sourcing cycle:

Procurement note: When specifying CRC (DC01/ST12) against GB equivalents, the surface-quality tolerance differs — EN 10130 cold-rolled coils carry tighter surface-class requirements than GB/T 5213. Verify with suppliers before converting specifications. Source verified grade-mapping documentation: RFQ Gateway

Procurement Action

Flat-Plate Buyers (HRC / CRC / Medium Plate): HRC remains in a tight band with spot $546.95/t sitting above the weekly average of $530/t — a $16.95/t premium that warrants caution on new spot orders. CRC at $606.40/t (weekly avg $589/t) offers a wider premium but stable demand signals. Medium plate (Q355B) at $604.91/t (-0.25%) presents a modest entry window. Consider locking HRC/CRC via forward contracts at current levels before the weekly average compresses further. Evaluate landed costs across trade lanes: Landed Cost Calculator

Long-Product Buyers (Angle / Channel / I-Beam): All three section steel grades averaged −USD 2/t (−0.4%) week-over-week with flat current spots. No directional urgency — hold and monitor. If project timelines extend beyond 30 days, consider early negotiation on Q235-based section steel at current $538–560/t levels before seasonal demand shifts in October.

Industrial Steel Buyers (Ship Plate / Cold Heading / Cold Forming): Ship plate (CCSAH36) at $622.75/t (+0.49%) is the only industrial grade gaining ground — a strong signal of order-book support in the marine sector. Cold heading steel (10B21, Φ8-20) at $570.73/t (−0.53%) and cold-forming coil (TECC) at $587.08/t (−0.26%) are in mild decline. Ship plate represents the clearest buy window; cold-heading and cold-forming grades favor a wait-and-see stance. Full freight-and-duty analysis available via: Landed Cost Calculator

Summary Stance: HRC and rebar favor a Strong Buy Window on spot orders; CRC and long products recommend Hold & Monitor; ship plate buyers should Lock in Freight Rates immediately given its +0.49% momentum.
