Confirm the supplied flat section before choosing a stainless material for fabrication.

Dimension label

The product name says flat bar, while the actual dimension choice says diameter 4–500 mm. Obtain a drawing identifying flat width and thickness rather than interpreting that label as a verified flat section.

Grade and thickness

The title requests 3–30 mm and several stainless grades, with a broader thickness range in the detail. Select one actual material and thickness with traceable evidence and a compatible cut size.

• Actual stainless designation
• Flat section drawing
• Thickness and usable width
• Cut length and edge criteria
• Selected surface and inspection

Finish requirements

BA, polished and several other surfaces are listed. Agree one finish and fabrication route; building material wording does not establish corrosion life, structural capacity or availability of every grade, section and surface combination.
