Define the actual flat bar outline and dimensions before selecting a stainless material.

Section form

The detailed type identifies flat steel bar and the shape says rectangular plate, while the actual dimension label says diameter 4–500 mm. Confirm the supplied outline, width and thickness with a drawing rather than assuming round bar.

Material and thickness

The title lists several stainless grades and a 3–30 mm requirement. Select one actual designation and thickness against the broader described scope, with material and dimensional evidence.

• Actual stainless designation
• Flat bar or plate outline
• Thickness and usable width
• Supply length and edge criteria
• Finish and fabrication acceptance

Surface requirements

BA and polished surfaces and hot and cold rolling are mentioned. Agree one finish and route; large stock and building wording does not establish availability, corrosion life or load capacity for every grade and section combination.
