Cut construction costs without cutting corners: Our S355JR carbon steel coils meet EN 10025-2 standards, holding strong at 355 MPa minimum yield strength. Why does this matter? When fabricating structural components, you'll consistently achieve 470-630 MPa tensile strength - verified through third-party SGS testing.
The secret's in the recipe: Max 0.22% carbon and 1.60% manganese content. This balanced formula delivers two killer advantages:
1.Welds stay crack-free even at -20℃ (Charpy impact >=27J certified).
2.Outperforms standard carbon steel by 15% in salt spray tests (ISO 9227).
Picture this: Using our coils for warehouse frames or trailer beds, you'll save up to 12% versus pricier alloys. One German contractor recently switched - their feedback? "We're getting 2x lifespan on coastal equipment versus generic coils." That's the S355JR difference: Tough as nails, priced right.
We offer two surface treatments: shot-blasted (Sa 2.5 standard per ISO 8501-1) for heavy-duty structural use and oiled (food-grade per FDA 21 CFR 178.3910) for rust protection during storage. The shot-blasted finish creates a uniform anchor pattern (50-80μm profile) that improves primer adhesion by 40%, critical for outdoor applications.
Our cut-to-length lines handle lengths from 2m to 12m with ±1mm tolerance, using high-speed saws that maintain precision even on 50-ton batches. We also provide edge rounding (radius 1-2mm per EN 10163-2) to prevent handling injuries and equipment damage.
As a Chinese manufacturer with 10 years of experience in supplying the foreign trade industry, we operate 5 of the world's most advanced rolling production lines with a total annual production capacity of 600,000 tons. Our quality control laboratory uses ultrasonic testing (compliant with EN 10160 standard) to check for internal defects, and each coil is 100% inspected before leaving the factory.
We keep 3,000-5,000 tons in stock at our warehouse, covering thicknesses 1.5-6.0mm and widths 1000-1500mm. Inventory updates in real time on our website, and shipments for in-stock S355jr Carbon Steel Coil leave within 72 hours-vital for meeting your urgent project deadlines.
Orders over 150 tons receive a 7% discount, plus free processing and 25% off ocean freight charges.
if any coil fails to meet EN 10025-2 mechanical properties or has surface defects exceeding 1mm² per m², we'll replace it within 7 days and refund associated freight costs. We also lock prices for 45 days on confirmed orders to shield you from market fluctuations.
