Product Features & Technical Specifications
- High Strength & Durability: S355J2 steel offers a minimum yield strength of 355 MPa, ensuring robust support for heavy bridge structures.
- Low-Temperature Impact Toughness: Each plate is impact tested at -20°C, meeting the requirements for cold-climate applications and preventing brittle fracture.
- Excellent Weldability: The controlled carbon equivalent (CEV) facilitates easy welding without preheating for most thicknesses, reducing fabrication costs.
- Wide Thickness Range: Available from 20mm to 100mm, we can supply plates for various bridge components, from girders to decks.
- Customizable Dimensions: Widths and lengths can be tailored to your project specifications, minimizing waste and optimizing material usage.
- Strict Quality Control: Every plate undergoes ultrasonic testing, hardness tests, and dimensional inspection to comply with EN 10025-2 and customer requirements.
- Surface Finish Options: Standard black surface, shot-blasted, or with primer as per your request.

Frequently Asked Questions (FAQ)
-
Q: What is the thickness tolerance for S355J2 plates?
A: The thickness tolerance follows EN 10025-2 requirements. Typically, for plates 20–100mm, the tolerance is within ±0.5mm to ±1.5mm depending on thickness. We can provide mill certificates with exact values. -
Q: Can you supply plates with certification for the impact test at -20°C?
A: Yes, all our S355J2 plates are impact tested at -20°C, and we provide a certified test report (EN 10204 type 3.1 or 3.2) upon request. -
Q: Do you offer cutting or drilling services for these plates?
A: Yes, we can provide custom cutting (plasma, laser, or flame), drilling, and beveling services to meet your fabrication needs. Please inquire for details. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 10 tons per size, but we can accommodate smaller quantities for trial orders or special projects. -
Q: How long does delivery take?
A: Lead time depends on quantity and thickness. Typically, 15–25 working days after order confirmation for standard sizes. Customized dimensions may require 20–30 days. -
Q: Can you provide third-party inspection?
A: Absolutely. We welcome inspections by SGS, Bureau Veritas, or any other accredited third-party agency. The cost can be arranged based on your requirements. -
Q: Are these plates suitable for welding without preheating?
A: For thicknesses up to 40mm, S355J2 can generally be welded without preheating under normal conditions. For thicker plates, a preheat of 100°C–150°C is recommended to avoid hydrogen cracking. We can provide welding guidelines. -
Q: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% balance before shipment), L/C at sight, and other flexible terms subject to negotiation.
