Steel sheet has four actual pairings of requested length with width ranges900–2000mm. Thickness2.0–3.5mm is a reference requiring exact selected dimensions.

Clarify the grade labels

Q345B/C/D/E andQ390/B/C are body references. Q345BC/BD/BE andQ420 title requests need actual designation confirmation without silent correction or assumed equivalence.

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

Specify mechanical tests

High-strength wording provides no measured yield, tensile or toughness result. Choose actual material and applicable standard scope.

Request service acceptance

Boiler/ship/high-pressure-vessel contexts do not establish approved pressure material, design stress or capacity. Request actual chemistry, mechanical tests and dimensional records before assigning the selected sheet to a project.
