SS201 is a cost-effective option for interior decoration, furniture frames and general structural parts. It has good forming performance and is suitable for projects where moderate corrosion resistance is acceptable.
SS304 is the most popular grade for 40×20mm rectangular tubes. It offers good corrosion resistance, high strength and excellent durability. It is widely used for stair handrails, balcony railings and outdoor decorative projects.
SS316 is recommended for coastal areas, chemical environments, marine applications and high-corrosion projects. It provides better corrosion resistance than SS304 and is suitable for demanding industrial and structural uses.
The 180G hairline surface is a fine brushed finish with consistent linear texture. It is widely used for stainless steel handrails, railings and decorative tubes because of its clean appearance and good scratch resistance.
Other finishes can be customized according to customer requirements.
