Constant-temperature Annealed VS Simplified Annealed Wire: On-machine Performance & Scrap Loss Full Comparison

Release time:

2026-07-29

Many wire mesh manufacturers only compare raw material price and ignore annealing technology. Simplified annealed wire seems cheaper per ton, yet hidden losses from wire breakage, machine downtime and defective products far exceed the price advantage.

Core Process Difference

Simplified annealing: Unstable furnace temperature, uneven heating for bundled wire, residual drawing stress cannot be fully eliminated. Constant-temperature continuous annealing: Closed-loop ±5℃ temperature control, uniform heating during continuous feeding, uniform grain structure and thorough stress relief.

On-site Production Contrast

Wire breakage rate Constant-temperature wire: ≤0.1% breakage rate, few production halts. Simplified annealed wire: 1.0%~1.2% breakage rate, frequent stop for rethreading.
Scrap rate Constant-temperature wire: 3%~4% Simplified annealed wire:12%~15%
Finished mesh quality Uniform ductility of constant-temperature wire guarantees flat mesh and consistent hole size. Uneven hardness of simplified wire causes wavy mesh and high rework rate.
Zinc coating integrity Balanced ductility avoids zinc peeling at twisting joints. Brittle under-annealed wire tears zinc layer easily during weaving, bringing hidden rust risks.

Cost Analysis

Simplified annealed wire saves about 200 RMB per ton on purchasing cost, but extra waste, labor and downtime loss reach nearly 900 RMB/ton, resulting in higher overall expenditure.

Inspection Standard

Fold wire tightly 5 times; simplified wire tends to crack and shed zinc powder. Trial weaving for 4 hours is the most reliable verification.

Conclusion

For high-speed automatic mesh production lines, constant-temperature annealed high-zinc galvanized wire is the optimal choice to cut comprehensive loss and stabilize long-term production efficiency.
