Use an exact grade suffix and material specification when selecting plate for construction engineering.

Designation and alloy

The title requests low alloy material and Q390D while the detail labels non-alloy and lists a narrower grade set. Confirm actual designation, chemistry and suffix instead of treating those descriptions as equivalent certified material.

Finished dimensions

The thickness description includes 2–3.5 mm or custom supply with actual custom length and width alternatives. Agree one actual thickness and finished cut size, including edge and dimensional acceptance for the project.

• Exact grade and suffix
• Actual alloy and test scope
• Thickness and finished dimensions
• Edges and delivered condition
• Construction design inspection

Mechanical evidence

High strength and boiler applications provide no measured material result. Request actual inspection records and engineering requirements; no certified yield, toughness, pressure approval or structural capacity is established for every title grade.
