Steel sheet has one actual pairing of requested length and1251–1500mm width range. Reference thickness is2.0–3.5mm and requires an exact selected value.

Clarify the grade designation

Q345B/C/D/E and Q390/B/C are body references. Q345BC/BD/BE and Q420 title labels need actual designation confirmation rather than silent correction or assumed equivalence.

• Flat-sheet shape.
• Non-alloy designation.
• Skin pass described.
• Cutting and bending services.
• ±1% tolerance reference.

Define the material standard

Choose applicable ASTM/GB/EN/JIS/BIS criteria and actual grade. High-strength wording supplies no measured yield, tensile or impact-toughness result.

Request service acceptance

Ship, boiler and high-pressure-vessel contexts do not establish approved pressure material or design stress. Request actual chemistry, mechanical tests and inspection scope for the selected sheet.
