Advanced Steel Plates – Engineered for Demanding Conditions
Product Overview
Our steel plate portfolio covers Carbon Structural, High‑Strength Low‑Alloy (HSLA), Wear‑Resistant, Weathering, Pressure Vessel, and Shipbuilding plates.
Key Performance Features
High Strength & Lightweight Design
Yield Strength: 235 MPa → 1100 MPa (grade dependent)
Tensile Strength: 400 MPa → 1250 MPa
Benefit: Reduce plate thickness by 15‑30% under the same load – lower structure weight, material cost, and freight.
Excellent Low‑Temperature Toughness
Impact energy (Charpy V‑notch, longitudinal): ≥ 47J at -20℃ down to -60℃
Applications: Arctic bridges, wind towers, LNG tanks, polar equipment.
Process: Calcium treatment & inclusion shape control; grain size ASTM 10 or finer.
Superior Weldability
Carbon Equivalent CEV: 0.32 – 0.45 (depending on grade)
Cold cracking sensitivity Pcm: ≤ 0.25
Advantage: Allows high heat input (up to 50 kJ/cm) with low or no preheating – no cracking after welding.
Surface & Anti‑Corrosion Options
As‑rolled / Black | Shot blasted | Primer coated
Weathering steel: Pre‑patinated stable rust layer – no painting needed, service life 4‑8 times longer than carbon steel.
Galvanized / Coil coated: Hot‑dip galvanized, PVDF or polyester paint – custom RAL colors.
Main Grades & Typical Applications
| Category | Typical Use |
|---|---|
| General structure | Workshops, footbridges, machinery |
| High strength | High‑rise buildings, transmission towers |
| Wear resistant | Buckets, dump bodies, crusher liners |
| Weathering | Railway cars, exposed bridges, façades |
| Pressure vessel | Boilers, tanks, heat exchangers |
| Ship plate | Hulls, hatch coamings, offshore decks |
Certification & Traceability
System: ISO 9001, ISO 14001, ISO 45001
Full traceability per unique heat / plate number. Documentation includes:
Chemical composition report (C, Si, Mn, P, S, alloying elements)
Tensile, bending, impact (specified temperature) test results
Ultrasonic inspection report (ASTM A578 / EN 10160)
Third‑party inspection (SGS / BV / TÜV) upon request
Processing & Delivery Services
Cutting: Plasma, laser, waterjet.
Beveling: CNC flame/plasma – Y / V / K types.
Drilling / Bending: Pre‑machined per drawing – less work on site.
Delivery condition: As‑rolled, normalized, TMCP, quenched + tempered.
Packaging & shipping: Fumigation‑free pallets / steel strapping / moisture‑proof wrapping.
Value Proposition
Lower total cost: Higher strength → less tonnage → reduced freight & installation cost.
Faster project completion: Easy weldability + pre‑processing → shorter fabrication time.
Lower risk: Full traceability + third‑party certificates → smooth project acceptance.
Sustainability: Weathering (no coating), lightweight design reduces carbon footprint.
