Verify actual base material and coating before accepting this coil against a requested specification.
Material identity
The title combines 15N20 and A792 G350 references, while the detailed grade says Q235 with other material codes. Agree the actual designation, applicable standard and coating composition rather than treating these names as equivalent supply.
Thickness discrepancy
The actual specification option is 2 mm, while the description gives 0.21–0.50 mm. Confirm the intended thickness and actual usable width before selecting coil or cut sheet form.
- Verified material designation
- Actual coating composition
- Confirmed thickness and width
- Supply form and length
- Material and coating inspection
Acceptance requirements
A 100 m length and zinc code are described without order-specific tests. Agree actual delivery and measurement criteria; full hard and high-strength wording does not establish hardness, mechanical values, code compliance or corrosion lifetime.
