FAQ
Q: What is the difference between cold rolled and hot rolled aluminum strip?
A: Cold rolled aluminum strip is processed at room temperature, providing higher dimensional accuracy, smoother surface quality, and more stable mechanical performance compared to hot rolled aluminum.
Q: What is your thickness tolerance?
A: Standard tolerance is ±0.01 mm – ±0.03 mm, depending on alloy and specification.
Q: Do you provide Mill Test Certificates (MTC)?
A: Yes. Each shipment includes a Mill Test Certificate showing chemical and mechanical data. Third-party inspection reports are also available upon request.
Q: Can you support OEM/custom production?
A: Yes. We support OEM manufacturing including alloy, temper, thickness, width, and surface treatment customization.
Q: How do you ensure batch consistency?
A: We use strict chemical control, automated rolling systems, real-time monitoring, and full batch traceability.
Q: What is your lead time?
A: Standard specifications: 7–15 days. Custom orders depend on technical requirements and production schedule.
