Product Name: Hot‑Rolled Steel Plate (>3.0 mm)
Introduction
Hot‑Rolled Steel Plate thicker than 3.0 mm is produced by reheating steel slabs above the recrystallization temperature and passing them through heavy‑duty rolling mills. The high‑temperature process delivers plates with excellent ductility, uniform mechanical properties, and robust surface hardness. These heavier‑gauge plates form the backbone of structural, pressure‑containment, and heavy‑equipment applications where strength, toughness, and formability are all critical.

Features & Advantages
High Structural Strength: Thick cross‑section provides superior load‑bearing capacity and rigidity.
Good Formability: Despite the heavy gauge, plates can be flame‑cut, bent, and rolled with minimal cracking when appropriate procedures are used.
Excellent Weldability: Standard carbon content and clean mill surface facilitate reliable welding with common processes (SMAW, SAW, FCAW).
Robust Durability: Suitable for heavy‑duty environments, such as bridge decks, foundation plates, and industrial machinery bases.
Versatile Finishes: Can be supplied with shot‑blast cleaning, pickling, or protective oil coatings to suit downstream painting or galvanizing.
Applications
Structural Fabrication: Base plates, stiffeners, and gussets in building and bridge construction.
Pressure Vessels & Tanks: Shell and head plates for boilers, reactors, and storage vessels.
Heavy Machinery: Machine beds, loader buckets, and chassis frames for mining and construction equipment.
Shipbuilding & Offshore: Hull plating, deck plating, and foundation plates for offshore platforms.
General Manufacturing: Cut‑to‑length blanks for CNC machining, laser cutting, and large‑format fabrication.
Packaging & Delivery
Packaging:
Plates stacked with timber or polymer spacers; strapped with steel bands and edged with protective angles.
Optional shot‑blast cleaning and rust‑preventive oil coating before wrapping in moisture‑resistant film.
Lead Time: Standard production and shipment within 20–30 days after order confirmation; expedited schedules (10–15 days) available for urgent requirements.
