Galvanized Steel Pipe Sizes: NPS, DN and Wall Thicknesss
A 2 inch galvanized pipe isn't 2 inches across, and NPS isn't DN. One reference table for NPS, DN, actual OD, and Schedule 40/80 wall thickness across the sizes buyers order most.

Cold rolled steel coil carries a published reference range of approximately USD 585–635 per metric ton. That range moves within itself based on grade, thickness, coil ID, and order volume — and several related products buyers search for alongside it, including rebar and hot rolled sheet, don’t have a confirmed public price at all yet.

Cold Rolled Steel Prices: Ranges and What Moves a Quote
A published reference range tells you the ballpark a mill is likely to quote from, not what your specific order will cost. Compared to typical index-tracker pages that report a single regional average, the breakdown below starts from actual product-line listing ranges and works through the variables that move an individual order within that range — grade, coating, thickness, volume, and Incoterms — so a quote can be sanity-checked against something more specific than a chart.
The table below covers products with a currently published, verifiable listing range. Products without one are addressed separately in the section that follows — they’re not omitted because they’re unimportant, but because publishing an estimated figure would violate this project’s price discipline standard.
| Product Line | Published Reference Range (USD/MT) | الحالة |
| PPGI / PPGL steel coil | ~460–650 | Confirmed listing range |
| لفائف فولاذية مدرفلة على البارد | ~585–635 | Confirmed listing range |
| أنابيب فولاذية مجلفنة | ~608–623 | Confirmed listing range |
| العارضة الفولاذية على شكل حرف H | ~440–568 | Confirmed listing range |
| منتجات فولاذية مختارة لأسقف المباني | ~410–450 | Confirmed listing range — see clarification note below |
Luyuan’s CR Coil listing runs 0.12–5.0 mm in thickness, with coil ID available in 508 mm or 610 mm. Related cold rolled products include CR Sheet at 0.20–0.50 mm and CR Rod in tool-steel-adjacent grades — 1.2436, D7, SKD2, and X210CrW12 — which sit in a different pricing tier from coil due to grade and processing differences. Manufacturing-application pages additionally reference SPCC, SPCD, and SPCE commercial cold rolled grades, the family most relevant to general fabrication and stamping buyers rather than tool-steel applications.
The published USD 585–635/MT range applies to standard CR coil rather than the tool-steel-grade CR Rod line, which typically carries a separate cost basis not covered by this listing range. If your RFQ is for CR Rod in one of the tool-steel grades above, treat the coil range as a non-reference point and request rod pricing separately.

Cold Rolled Steel Prices: Ranges and What Moves a Quote
Several of the products buyers search for alongside cold rolled steel prices — deformed steel bar/rebar, hot rolled sheet, galvanized steel coil, and round steel bar — don’t have a confirmed listing price in Luyuan’s current resource library. That’s a gap in published data, not a gap in supply capability, and it’s handled the same way across this entire content program: no figure is estimated or interpolated from an adjacent product’s range.
| Product Searched | Confirmed Price Status | Note |
| Deformed steel bar / rebar (HRB400, HRB500) | السعر حسب الطلب | No published listing range in current resource library |
| Hot rolled sheet | السعر حسب الطلب | HR Coil and HR Sheet exist as products; neither carries a published price range |
| Galvanized steel coil (GI / Galvalume) | السعر حسب الطلب | المجلفن pipe has a published range; galvanized coil does not — these are separate products |
| Round steel bar | السعر حسب الطلب | Applies across CR Rod, HR Rod, and stainless bar; none carry a published range |
A supplier quoting a firm number for any of these products without referencing a current mill confirmation is quoting from something other than published data — worth a direct follow-up question before treating it as comparable to the ranges above.
The resource library lists “selected roofing steel products” at USD 410–450/MT alongside PPGI/PPGL at USD 460–650/MT. The lower bound of the roofing category sits below the lower bound of the PPGI range, which raises a fair question: is roofing steel a separate, lower-cost product line, or does it overlap with PPGI’s lower end and reflect a labeling inconsistency in the source listing?
This hasn’t been internally resolved as of publication. Rather than merge the two ranges or guess which one is correct, they’re presented here as they appear in the source listing — as two distinct categories — with the overlap flagged for buyers to confirm directly: if you’re quoting “roofing steel” against a project that specifies PPGI coating class, ask the supplier explicitly whether the roofing-steel quote includes a color coating, or whether it’s an uncoated or differently processed product priced below the PPGI band for that reason.
| Variable | How It Moves Price |
| الصف | Higher-strength or tighter-tolerance grades (e.g., API 5CT pipe grades vs. standard structural grades) generally price above baseline within a product family |
| Coating weight / class | Heavier zinc coating (higher Z-class or AZ weight) adds material cost per ton |
| Thickness and dimensional tolerance | Thinner gauges and tighter tolerance bands typically cost more per ton to produce consistently |
| Order volume | Larger tonnage orders generally move toward the lower end of a published range; small or mixed-SKU orders trend toward the higher end |
| Incoterms and destination | FOB, CFR, and CIF quotes aren’t directly comparable — freight, insurance, and destination port all sit outside the base material price |
| متطلبات التفتيش | Third-party inspection (SGS, BV, Intertek, or a buyer-appointed inspector) beyond Luyuan’s standard 100% pre-shipment inspection can add cost depending on scope |
Material grade specification itself is generally set against ASTM or equivalent GB standards, and that specification — not just the raw tonnage — is what a mill prices against; two orders at the same weight but different grade call-outs won’t return the same quote.

Cold Rolled Steel Prices: Ranges and What Moves a Quote
A: Approximately USD 585–635 per metric ton, as a reference listing range — final pricing depends on grade, thickness, coil ID, and order volume.
A: Luyuan’s published reference range for H-beam steel is approximately USD 440–568 per metric ton, varying by section, grade, and volume.
A: There’s no published listing range for rebar in the current resource library. Treat it as price on request and confirm current pricing directly.
A: Hot rolled sheet doesn’t currently carry a published price range. Request a current quote rather than assuming it falls near cold rolled or PPGI pricing, since production process and cost basis differ.
A: No — these are separate products. Galvanized steel pipe has a published reference range (~USD 608–623/MT); galvanized coil (GI or Galvalume) does not currently have a confirmed published range.
A: This varies by material family — CR Rod, HR Rod, and stainless bar are all considered “round bar” depending on context — and none currently carry a published price range. Request a quote specifying the exact grade.
A: This overlap is currently unresolved in the source data. The two are published as separate categories with different ranges; confirm directly with the supplier whether a roofing-steel quote includes the same coating class as PPGI before comparing them.
A: Yes — larger tonnage orders generally trend toward the lower end of a published range, while small or mixed-SKU orders trend toward the higher end.
A: Most commonly it’s an Incoterms mismatch (FOB vs. CIF), a grade or coating specification difference, or a volume difference — confirm all three before assuming one quote is simply cheaper.
A 2 inch galvanized pipe isn't 2 inches across, and NPS isn't DN. One reference table for NPS, DN, actual OD, and Schedule 40/80 wall thickness across the sizes buyers order most.
H beam and I beam aren't interchangeable terms. Compare flange geometry, axis behavior, HW/HM/HN vs. W-shape vs. IPE/HEA designations, and confirmed Luyuan H beam specs before you spec a project.
