Steel plates remain one of the most widely used materials in construction, manufacturing, and heavy engineering. For European buyers, EN10025-certified steel plates are the benchmark for structural quality. In the United States, ASTM A-series steel plates are equally important for compliance with American engineering standards.
In this guide, we break down EN10025 steel plate cost per kg in Europe and ASTM A steel plate price per square meter in the USA, with practical tips for procurement teams and contractors.
1. EN10025 Steel Plate – Overview
EN 10025 is the European standard for hot-rolled structural steels. Popular grades include:
-
S235JR – General-purpose structural steel
-
S275JR – Medium strength, good weldability
-
S355JR/J2 – High strength for demanding applications
-
S355K2 – Impact-tested for sub-zero temperatures
These grades are widely used in:
-
Bridges and building structures
-
Offshore platforms
-
Heavy machinery frames
-
Shipbuilding
-
Wind turbine towers
2. EN10025 Steel Plate Cost per kg in Europe
In Europe, steel prices are typically quoted per ton for bulk orders, but breaking them down per kilogram helps small-scale buyers and cost estimators.
Typical 2025 European price ranges (subject to market changes):
| Grade | Price Range (€/kg) | Notes |
|---|---|---|
| S235JR | €0.60 – €0.75 | Most economical structural steel |
| S275JR | €0.65 – €0.80 | Balanced price and strength |
| S355JR / S355J2 | €0.70 – €0.90 | High-strength steel for heavy-duty projects |
| S355K2 | €0.75 – €0.95 | Impact-tested for cold climates |
Pricing factors in Europe:
-
Grade – Higher strength grades cost more.
-
Plate thickness – Thicker plates have slightly higher €/kg rates.
-
Order size – Bulk orders over 20 tons often receive discounts.
-
Market trends – Prices can change monthly based on demand and raw material costs.
3. Buying EN10025 Steel Plate in Europe
Where to buy:
-
Steel mills with direct sales
-
Large distributors/stockholders
-
Online steel marketplaces
-
Regional steel service centers
Buying tips:
-
Compare multiple suppliers to get the best €/kg rate.
-
Ask for Mill Test Certificates (MTC) to confirm EN10025 compliance.
-
Factor in delivery charges when comparing suppliers.
4. ASTM A Steel Plate – Overview
In the United States, ASTM (American Society for Testing and Materials) standards define steel grades for structural, pressure vessel, and general engineering applications.
Popular ASTM A-series steel plate grades:
-
ASTM A36 – Mild structural steel (similar to EN S235JR)
-
ASTM A572 Grade 50 – High-strength low-alloy steel
-
ASTM A516 Grade 70 – Pressure vessel steel
-
ASTM A1008 CS Type B – Cold rolled commercial steel sheet
5. ASTM A Steel Plate Price per Square Meter in USA
Steel prices in the U.S. are usually quoted per ton, but for specific fabrication projects, per square meter pricing is more practical.
To calculate price per m², you need:
-
Steel density – ~7850 kg/m³
-
Plate thickness – Measured in millimeters
-
Price per ton – Market rate for the grade
Formula:
Price per m² = (Thickness in mm × 7.85 kg/m² per mm thickness) × Price per kg
Example price ranges in the USA (2025):
| ASTM Grade | Thickness | Price Range ($/m²) | Notes |
|---|---|---|---|
| ASTM A36 | 10 mm | $51 – $63 | Standard structural steel |
| ASTM A572 Gr. 50 | 10 mm | $55 – $70 | Higher strength |
| ASTM A516 Gr. 70 | 10 mm | $59 – $75 | Pressure vessel steel |
| ASTM A1008 CS Type B | 3 mm | $17 – $22 | Cold rolled sheet |
6. Factors Affecting ASTM Steel Plate Price per m² in USA
-
Grade – Higher alloy content means higher price.
-
Thickness – Price scales with weight per square meter.
-
Certification – Offshore or nuclear-grade certification adds cost.
-
Market trends – Scrap steel and iron ore price fluctuations affect wholesale prices.
7. Comparing EN10025 €/kg and ASTM $/m² Pricing
While EN10025 dominates in Europe and ASTM in the U.S., both pricing models can be converted:
-
1 €/kg ≈ $1000 per metric ton
-
1 m² of 10 mm plate ≈ 78.5 kg
-
Conversion allows international buyers to compare cross-market prices before importing.
8. Sourcing Strategies
For Europe (EN10025):
-
Time purchases before seasonal demand peaks.
-
Negotiate bulk discounts with mills and distributors.
-
Consider alternative grades if specs allow.
For USA (ASTM):
-
Compare mill-direct vs distributor prices.
-
Check regional freight rates for heavy plate deliveries.
-
Look for dual-certified plates if projects are international.
9. Final Takeaways
-
EN10025 steel plate cost per kg in Europe (2025) ranges from €0.60 to €0.95, depending on grade and order volume.
-
ASTM A steel plate price per m² in USA (2025) ranges from $17 to $75, depending on grade and thickness.
-
For large projects, even small differences in €/kg or $/m² can mean significant cost savings.
-
Working with reputable suppliers and tracking market trends is key to getting the best deal.
