From architecture and automotive to process piping and instrumentation, Stellanox Steel’s stainless steel tubes deliver superior performance, precision, and long-term durability across diverse industries.
What are Stainless Steel Tubes?
Stainless Steel Tubes are hollow cylindrical products made from corrosion-resistant stainless steel alloys, crafted through seamless or welded processes. Tubes differ from pipes primarily by their emphasis on precise outer diameter (OD) measurements and wall thickness rather than fluid transport.
They are extensively used in structural, mechanical, and decorative applications where strength, aesthetic appeal, and reliability are paramount. With exceptional resistance to oxidation, chemicals, and high temperatures, stainless steel tubes are vital for industries that demand uncompromising quality and appearance.
