Products Description

Cut construction costs without cutting corners. Our S355JR carbon steel coils meet EN 10025-2 standards and maintain a minimum yield strength of 355 MPa.

The secret's in the recipe: a maximum of 0.22% carbon and 1.60% manganese content. This balanced formula delivers two key advantages:

Crack-free welding even at temperatures as low as -20°C.

A 15% longer lifespan in salt spray tests compared to standard carbon steel.

Picture this: Using our coils for warehouse frames or trailer beds, you'll save up to 12% versus pricier alloys. Last year, a German contractor made the switch. Their feedback? "We're getting twice the lifespan on coastal equipment compared to generic coils."

Factory Processing

We offer two surface treatments: shot-blasting for heavy-duty structural applications and oiling for rust protection during storage. The shot-blasted finish creates a uniform anchor pattern that improves primer adhesion by 40%-a critical factor for outdoor applications.

Our cut-to-length lines handle lengths from 2m to 12m, using high-speed saws that maintain precision even with 50-ton batches. We also provide edge rounding to prevent handling injuries and equipment damage.

Production Strength

As a Chinese manufacturer with 20 years of experience in supplying the foreign trade industry, we operate 5 of the rolling production lines with a total annual production capacity of 600000 tons.

Our quality control laboratory uses ultrasonic testing to check for internal defects, and each coil is 100% inspected before leaving the factory. We keep 3,000 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.

Factory Commitments

Orders over 150 tons receive a 7% discount, plus free processing and 25% off ocean freight charges.

Here's our guarantee: if any coil fails to meet mechanical properties, 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.
