Precision in every layer.

From incoming coil to final shipment

Consistency, built in.

Consistency is built into every critical step—not checked only at the end.

1. 01

   Incoming material control

   Verification
   01Incoming material control

   

   • Raw materials from CHALCO and China Hongqiao Group.
   • 100% primary aluminium and same-alloy production scrap.
   • Incoming materials inspected and cross-checked upon arrival.
2. 02

   Surface cleaning & drying

   Preparation
   02Surface cleaning & drying

   

   • Removes rolling oil, aluminium fines and dust.
   • Neutralised with no acid or alkali residue.
   • Surface-monitored for a defect-free finish.
3. 03

   Coating & perforation

   Adaptation
   03Coating & perforation

   

   • Precision tooling for burr-free perforation.
   • Multiple hole diameters available.
   • Made with 100% virgin adhesive resin.
4. 04

   Precision slitting

   Conversion
   04Precision slitting

   

   • H18 slitting protects the aluminium surface.
   • Precision knife setup with zero deviation.
   • Rotary slitting delivers flat, burr-free strip.
5. 05

   Controlled annealing

   Performance
   05Controlled annealing

   

   • Small-coil heat treatment ensures efficient, uniform recrystallisation.
   • A dedicated process plan for every batch ensures consistency.
   • Final material properties are independently controlled.
6. 06

   Protective packaging

   Delivery
   06Protective packaging

   

   • Vacuum-packed against moisture and impact.
   • Steel-strapped for long-distance transport.
   • Custom pallets maximise container space.
