# Round Stainless Steel Rod
When it comes to stainless steel rods, they come in various shapes, including flat, hexagonal, round, and square. Among these, round stainless steel rods are particularly popular due to their versatility and aesthetic appeal.
The absolute roughness of hot-rolled stainless steel round bars tends to be higher compared to cold-drawn ones. While this difference might not pose an issue when the rods are used primarily for their strength and corrosion-resistant properties, it becomes crucial when aesthetics and outdoor durability are priorities. For such cases, cold-drawn stainless steel round bars are highly recommended thanks to their smooth surface and lower absolute roughness. These bars are available in a wide range of sizes, with typical diameters ranging from 5mm to 450mm. For a comprehensive price list and size chart, feel free to reach out to us.
