Raw Surface of Stainless Steel Pipes:
NO.1 Surface treated with heat and pickling after hot rolling. Generally used for cold-rolled materials, industrial tanks, chemical industrial equipment, etc., with thicknesses ranging from 2.0mm to 8.0mm. Stainless steel pipe processing plants also offer matte finishes.
NO.2B Surface treated with heat and pickling after cold rolling, followed by precision rolling to achieve a moderately bright surface. Due to its smooth surface, it is easy to re-grind for even brighter finishes, and it has a wide range of applications, such as tableware and building materials. With surface treatments to improve mechanical properties, it can meet almost all applications.
Rough Surface of Stainless Steel Pipes:
NO.2D Surface treated with heat and pickling after cold rolling. It is soft and has a silvery-white luster, used for deep drawing processes, such as automotive components and water pipes.
Coarse Grit Stainless Steel Pipes:
NO.3 Surface ground with 100-120 grit abrasive belt. It has a good gloss and discontinuous coarse texture. Used for interior and exterior building decoration materials, electrical appliances, and kitchen equipment. Fine sandblasting is also a surface finish grade frequently produced by stainless steel pipe processing plants.
Besides the classifications mentioned above, stainless steel pipe products produced by processing plants also come in many other surface finish grades. Bright finish has a particularly high gloss and can be used directly to make mirrors or other decorative products, offering an attractive appearance and maintaining its shine for a long time without the risk of corrosion. The specific surface finish grade to choose depends on the characteristics of the product, aiming for both aesthetics and practicality.
