Frequently Asked Questions (FAQ):

Q: What is the primary difference between a metal sheet and a metal plate?

A: The main distinction lies in thickness. Generally, flat metal products under 6.0 mm (or 1/4 inch) in thickness are classified as metal sheets, which are commonly supplied in coils or flattened cut lengths. Flat products with a thickness of 6.0 mm and above are designated as metal plates, engineered for heavy load-bearing structural, marine, and pressure vessel applications.

Q: What custom cutting and metal fabrication services does XQJ Metal provide?

A: We provide complete secondary processing, including high-precision fiber laser cutting for complex geometries, CNC plasma and oxy-fuel flame cutting for thick carbon plates, press brake bending, hole punching, surface grinding, and laser-grade PVC protective film application.

Q: Do you supply official Mill Test Certificates (MTC) and ultrasonic flaw detection (UT) reports?

A: Yes, every XQJ Metal sheet and plate shipment is accompanied by official EN 10204 3.1 Mill Test Certificates detailing heat numbers, chemical composition, and mechanical test results. For heavy structural and vessel plates, we also furnish Ultrasonic Testing (UT) inspection reports upon request.

Q: What is the MOQ and standard lead time for wholesale sheet and plate orders?

A: Our standard MOQ for stock grades and standard sizes is 500 kg to 1 metric ton. Standard delivery lead time for in-stock sheets and plates is 3–5 business days, while custom cut, bent, or surface-treated orders typically take 7–12 business days.
