Product Surface
| Surface finish | Characteristics & Application |
| NO.1 | Hot-rolled surface,annealed and pickled,can be used as cold-rolling material,industial tanks and chem i cal devices. |
| 2D | Cold-rolled, an nealed and pick led with out skinpassing the dull prod ucts can be used as auto mo bile parts, build ing materrials and pipings. |
| 2B | The surface brightness and flatness of NO.2B is better than NO.2D. Then through a special surfacetreament to improve its mechamical properties, N02B could nearly satisfy com pre hen sive uses. |
| NO.3 | Polished with abra sive belt of grit #100#120,have bet ter bright ness with dis con tin u ous coarse stria, used as in ner and ex ter nal or na ments for building, elec tri cal ap pli anc es and kitchen uten sils etc. |
| NO.4 | Polished with abrasive belt of grit #150#180, have better brightness with discontinuous coarse stria, but thinner than NO.3, are used as bathtud buildinginner and external ornaments electrical appliances, kitchen utensils and food processing equipment etc. |
| HL | Polished with abrasive belt of grit #150-320 on the No.4 finish and has continuous streaks, mainly used as building ornaments, elevators, door of building, frontal plate etc. |
| BA | Cold rolled, bright an nealed and skin passed, the prod uct has ex cel lent bright ness and good re flex iv i ty like mirror, used for lectrical appliances, mirror, kitch en apparatus, or na ment ma te ri als etc. |
Production Process
Product Description
316/304/201 Rectangular Tube Stainless Steel offers tailored performance across grades. 316, with added molybdenum, delivers superior corrosion resistance, ideal for marine, chemical, and high-salt environments. 304 provides balanced durability for general use—architecture, food processing, and industrial frameworks. 201 offers cost-effective reliability for less harsh settings. Their rectangular profile ensures excellent structural stability, perfect for load-bearing frames, supports, and architectural designs. All grades feature good weldability and formability, adapting to cutting, bending, and fabrication. Smooth surfaces simplify maintenance, while stainless steel’s inherent rust resistance ensures longevity indoors and outdoors, suiting diverse industrial and decorative applications.Stainless steel square tubes are easy to cut, weld and bend, and can be conveniently processed into various shapes, making them suitable for the design and construction of complex structures.
