Why Choose S355JR Hot Rolled Structural Steel Plate

Refined steelmaking and controlled rolling deliver a consistent yield strength (≥ 355 MPa) for dependable structural integrity.

Low carbon equivalent (CEV ≤ 0.45%) minimizes the need for preheating, reducing fabrication time and processing costs.

Guaranteed Charpy V-notch toughness (≥ 27 J at +20°C) ensures reliable safety margins under ambient operating conditions.

Controlled elongation (20%–22%) supports smooth cold bending, punching, and cutting without edge cracking.

Strict compliance with EN 10029 standards guarantees uniform thickness and flatness to simplify automated shop fit-up.

In-House Value-Added Processing

Precision Cutting: Oxy-fuel flame cutting and plasma cutting tailored to your shop drawings.

Surface Preparation: Shot blasting to SA 2.5 standard and weldable shop primer application.

Edge Preparation: Beveling, edge milling, and custom hole punching.

FAQ

Q: What third-party inspections do you support before shipment?

A: We regularly accommodate pre-shipment inspections by SGS, Bureau Veritas (BV), TÜV, and Lloyd's Register (LR) to verify dimensions, surface quality, and quantity.

Q: What is your typical production lead time for non-stock orders?

A: Custom mill rolling runs generally take 20 to 30 days, depending on the required thickness, width, and total order volume.

Q: Can you supply plates with edge processing or custom surface coatings?

A: Yes, we offer flame cutting, beveling, shot blasting (SA 2.5), and shop priming based on your project processing specifications.

Q: How do you prevent rust and transit damage during ocean freight?

A: Plates are secured with heavy-duty steel strapping, edge protectors, and optional anti-rust oil or waterproof wrapping for breakbulk and container shipping.

Q: Are mill test reports provided before the vessel departs?

A: Official EN 10204 3.1 certificates linked to your specific heat numbers are issued and emailed as soon as final laboratory testing is completed.
