Confirm the actual supplied plate before preparing construction welding or cutting requirements.

Material evidence

The grade field states Q235B while the material field lists Q345 and Q390 variants and the title also requests A36. Select one actual designation with applicable inspection rather than treating the mixed fields as equivalent verified grades.

Thickness and cut

The requested 10–50 mm scope differs from the detailed 2–3.5 mm range. Confirm actual thickness and tolerance with finished width and requested length, keeping the title request separate from confirmed supply.

• Actual material designation
• Confirmed thickness and tolerance
• Finished width and length
• Joint edges and surface
• Construction process inspection

Project acceptance

Welding, boiler and pressure vessel labels contain no qualified process or design result. Request actual material records; no certified strength, qualified weld, pressure capability or structural load rating is established.
