Our Company 

♦ We have implemented standardized processes to enhance work efficiency, reduce confusion,

  minimize errors, and boost overall productivity.

♦ A comfortable and well-lit work environment, combined with a reasonably arranged office layout,

  fosters a positive work attitude, healthy interpersonal relationships, and sustained team growth

  motivation, while enhancing team cohesion and a sense of belonging.

Our factory own the world advanced equipments, include:

Our samples:

We are good at medium and thick 5xxx/6xxx series aluminum plates product, and produced

some samples for display. Most samples are used for automobile and railway transportation fields.

Ocean Shipping

For oversize plate, we use Flat Rack Container for shipping

1) We use suitable securing material, such as wooden blocks, steel straps, and ratchet

    tie-downs to firmly fix the aluminum plates to the flat rack.

2) To prevent possible exposure to seawater or rain, we cover the entire cargo with

     waterproof tarps.

3) We make sure these sheets are loaded with a low and evenly distributed center of

    gravity to avoid tilting during the transportation.

Key Performance Advantages

1)  Lightweight Superiority

   • Exceptional Strength-to-Weight Ratio

     7XXX series (e.g., 7050) offers tensile strength up to 570MPa with density of only 2.8g/cm³ -

     1.8× higher specific strength than Q345 steel, ideal for aerospace/military weight reduction.

  • Structural Efficiency

    Single thick plates eliminate multi-layer welding, avoiding joint weakening (e.g., 200mm 5083-H321

    ship decks reduce fasteners by 50%).

2)  Environmental Resistance

   • Extreme Temperature Stability

    5XXX series (e.g., 5083) maintains toughness at -196℃ (LNG storage) with no cold brittleness.

    2XXX series (e.g., 2219) withstands short-term 300℃ exposure (rocket engine compartments).

  • Corrosion Resistance

    Natural corrosion rate <0.02mm/year (5083 in marine environments), eliminating protective coatings.

    Nuclear-grade 5052 resists radiation oxidation with >40-year service life.

3)  Manufacturing Benefits

   • Machinability

     6XXX series (6082-T6) achieves surface roughness Ra≤1.6μm with 1/3 the tool wear of steel.

  • Weldability

    2219 plates achieve 90% base metal strength using VPPA welding.
