Dimensions of 304 Stainless Rectangle Tube
Stainless steel rectangular tube provides an outstanding combination of strength, durability, and corrosion resistant properties. The chromium content in stainless rectangular tube (minimum 10.5% by mass) gives it natural corrosion resistance that can withstand chemicals, fresh water, salt water, and more, making it ideal for outdoor installations and other harsh environments where carbon steel rectangular tubing would quickly fail.

Stainless rectangular tube is popular for a wide range of uses, including:

  • Construction and architecture
  • Structural applications
  • Outdoor framework, braces, and supports
  • Marine/seawater applications
