At Metric Metal, we supply high-quality stainless steel square tubes. These tubes are available in different grades and sizes, so we can accommodate your specific tube preferences and needs.

What Is a Stainless Steel Square Tube?

A stainless steel square tube is a long bar of steel that has a hollow interior. It got its name from its square cross-section. Since it’s made of steel, it’s highly durable. It’s likewise resistant to corrosion, rust, and stains. These tubes can even withstand acid, salt water, and chemical exposure.

This type of tube is divided into two categories — seamless steel pipes and welded steel pipes. As its name suggests, a seamless steel pipe has a smooth and unobstructed composition and lacks any welds on the surface. Meanwhile, a welded steel pipe has a bent steel plate that is welded into a square shape, creating a seam on the pipe’s body.

Common Uses for Stainless Steel Square Tube

The resistance of stainless steel square tubes gives them a wide scope of outdoor applications. Their hollow interior makes them excellent for transporting fluids like gasoline, water, and other petroleum products too.

Despite their robust structure, these tubes are relatively light and can be bent to accommodate different use cases. They’re also essential components in the production of certain equipment, mechanical parts, and industrial infrastructure.

Here are some of the products, systems, and structures that use stainless steel square tubes:

  • Cookware and other heavy food processing equipment
  • Architectural wall paneling
  • Exterior railings and bracket trims
  • Quarrying and water filtration systems
  • Heat exchangers
  • Mining screens
  • Chemical repositories
  • Heavy duty springs
  • Petroleum pipelines
