RUNYING Steel Group is a premier Tangshan-based manufacturer and exporter supplying high-quality Hot Rolled Carbon Steel Sheets and Structural Heavy Steel Plates (including popular 4x8 ft sheet metal sizes and heavy-gage structural plates up to 200mm thickness).

Certified under ISO 9001 Quality Management System standards, our hot-rolled steel plates are manufactured to strict dimensional tolerances (EN 10051 / EN 10029) and comply with ASTM A36, EN 10025 (S235JR / S355JR / S355J2), JIS SS400, and GB (Q235 / Q355) standards for heavy building construction, pressure vessels, offshore platforms, and heavy machinery fabrication.

Technical Specifications & Primary Steel Grades

Below are the engineering parameters, dimension ranges, and international standards for our hot rolled carbon steel sheets and structural plates:

Key Mechanical & Performance Advantages

1. Heavy-Duty Structural Performance:

Heavy plate section modulus up to 133,000 mm³/m for high load-bearing steel structures.

Superior low-temperature impact toughness (≥27J@-20℃ for S355J2 grade).

2. Cost-Effective Fabrication & Excellent Weldability:

Controlled carbon equivalent (CEV≤0.45%) for clean flame/laser cutting and crack-free structural welding (Pcm≤0.25%).

3. Custom Precision Processing Capabilities:

Custom cut-to-size options based on project shop drawings (4x8 ft, 5x10 ft , or custom lengths up to 18m).

Ultrasonic Testing (UT) to EN 10160 S1E1 standard available upon request.

Universal Applications & Industry Sectors

Building Construction & Infrastructure: Structural steel columns, heavy girders, base anchor plates, and cross-sea bridge girders.

Machinery & Heavy Equipment: Excavator track shoes, mobile crane booms, industrial machine bases, and stamping dies.

Energy & Storage Facilities: Wind tower flange plates, pressure vessel walls, and oil storage tank shells.

Seaworthy Export Packaging & Logistics via Tianjin Port

To protect carbon steel plates against deformation and surface oxidation during long-distance ocean transport, our products are shipped under strict export controls:

Heavy-Duty Plate Stacking: Firmly strapped with high-tensile steel straps, fitted with protective corner protectors and pre-rigged lifting slings.

Moisture Protection: Anti-rust oiled coating or VCI moisture barrier wrapping applied prior to container loading.

Container Payload Optimization: Cut to 5.85m for 20ft containers or 11.8m for 40ft GP/HQ containers to maximize payload capacity up to 26-27 Mrtric Tons.
