Advanced Manufacturing Infrastructure & Facilities
Haomei Aluminum operates an expansive sheet and plate production facility covering 1,200,000 m² (with 500,000 m² of modern workshops). Our heavy-duty production infrastructure ensures unmatched dimensional consistency, internal integrity, and mechanical reliability for international shipbuilding and offshore projects:
- Hot & Cold Rolling Lines: Equipped with a state-of-the-art 1+4 hot tandem rolling line, 4 advanced cold mill lines, and 5 foil mill lines.
- Global-Scale Extrusion Capability: Features a world-class 150MN direct and indirect extrusion press (supplied by SMS Germany), capable of producing high-performance structural extrusions with a maximum section of 0.45 m² for marine superstructures and rail transit.
- Rigorous Heat Treatment: Integrated 30m vertical and 40m horizontal quenching furnaces, automated stretching, and aging facilities ensuring precise temper control (such as H116 and H321 for 5083 alloys).
Marine Aluminum Manufacturing Capability & Mill Infrastructure
Haomei Aluminum operates integrated heavy rolling mills, modern extrusion lines, and precision finishing workshops designed to fulfill strict commercial and military shipbuilding contracts.
Heavy Plate Rolling Mills
Equipped with 1+4 hot rolling lines and cold rolling mills capable of producing marine plates up to 2,600mm width and 16,000mm length, reducing total weld seams required in shipyard hull construction.
Extrusion Lines & Tonnage
Multiple hydraulic extrusion presses ranging from 1,000 to 10,000 tons, delivering complex structural profiles, bulb flats, and hollow sections with tight dimensional tolerances.
Heavy-Duty Plate Stretching & Leveling Machine
Advanced high-tonnage hydraulic tension leveling and stretching equipment eliminating internal residual stresses, ensuring superior flatness and dimensional stability during subsequent shipyard CNC plasma cutting.
Large-Scale CNC Gantry Milling & Beveling Centers
Precision CNC gantry machining centers capable of handling long structural profiles and plates, providing custom edge preparation, welding bevels, and tight-tolerance machining for direct shipyard assembly.
Surface Treatment & Flatness Correction
Advanced roller leveling and tension leveling equipment ensuring superior plate flatness, paired with controlled degreasing and protective film application.
Testing & Quality Assurance Lab
In-house spectroscopic analysis, automated ultrasonic internal defect scanning, and destructive tensile/exfoliation corrosion testing laboratories meeting EN 10204 3.1 standards.
Manufacturing Route & Strict Quality Control
Every batch of marine aluminum plate undergoes a strict, traceable manufacturing route aligned with ASTM B928 and global marine standards:
- Raw Material Inspection: Chemical composition and metallurgical structure verification.
- Hot/Cold Rolling & Temper Control: Precise thickness reduction and microstructural stabilization (e.g., 5083-O, H112, H116, H321).
- Precision Cutting & Leveling: Tailored dimensional schedules supporting plates up to 305mm thickness, 3800mm width, and 27,000mm length.
- Non-Destructive Testing (NDT): Comprehensive ultrasonic testing (UT) and surface inspection.
- Export Packaging: Moisture-barrier, seaworthy protective packaging designed for global transit to over 40 countries (including the USA, UK, Germany, Singapore, and Brazil).
Verified Classification Society Certifications
