3. Efficient and automated production
Equipped with high-speed punching machines and automated production lines, it supports fast delivery of large-volume orders and reduces costs.
4. Strict quality inspection
Through hardness testing, salt spray testing, three-dimensional measurement and other tests, it complies with ISO 9001 and industry standards.
5. Flexible customization service
Support non-standard design, provide surface treatment (electroplating, spraying, passivation, etc.) and packaging customization to meet diverse needs.

1. Raw material slitting: Cut metal coils according to product specifications to ensure maximum material utilization.
2. Precision stamping: Punching, bending, stretching and other processes are completed through high-speed punching machines and molds to form complex structures in one go.
3. Surface treatment: Anti-rust, electroplating or spraying as needed to improve weather resistance and aesthetics.
4. Quality inspection: Full-process random inspection + final inspection to ensure that the size and performance meet the standards.
5. Packaging and delivery: Use shock-proof and moisture-proof packaging, support customized services such as labeling and boxing, and ship on time.
