Process Comparison
| Conventional Process | Our Bright Annealing Process |
|---|---|
| Hot rolled / cold drawn → Conventional annealing → Heavy oxidation → Pickling / shot blasting required → Material loss | Cold drawn / cold rolled → Bright annealing in controlled atmosphere → Clean, bright surface → Ready for use / finishing |
| Disadvantages: Multiple steps, pickling waste, wall thickness loss, rough surface | Advantages: Streamlined process, environmentally friendly, precise dimensions, superior surface finish |
