Stainless Steel Expanded Metal


Stainless Steel Expanded Metal

Featuring diamond-shaped openings that impede access without obstructing visibility, expanded metal is suitable for everything from architectural accents to industrial safety guards. For applications where exposure to moisture, chemicals, extreme temperatures, and other harmful factors are expected, a material with elevated performance characteristics is beneficial.

Expanded metal made from stainless steel offers superior strength, corrosion resistance, and aesthetic appeal in a lightweight package.

Marco Specialty Steel is your metal supplier and fabricator. We will deliver it, cut it to size, or weld it to your specifications.

Benefits of Stainless Steel Expanded Metal

Stainless steel is a group of iron-based alloys with a minimum of roughly 11 percent chromium, which inhibits rust and withstands extreme temperatures. The material also has a long cycle life and is fully recyclable, making it environmentally friendly.

There are more than 150 grades of stainless steel, and a handful are utilized for expanded metal applications. Specific performance characteristics vary by grade, but here are common traits.

  • Easily fabricated; cut, form, or weld
  • Resists corrosion
  • High strength
  • Low weight
  • Easy to clean
  • Stands up to high temperatures
  • Simple to sterilize
  • Withstands low temperatures
  • Shiny, aesthetically pleasing appearance
  • Good weldability
  • Strong formability
  • Resists magnetism, in some cases

When subjected to impact forces, stainless steel’s protective surface oxide layer self-heals. Unlike other materials, areas of stainless steel tubing that sustain nicks, marks, scratches, or other forms of damage are safe from degradation.

Stainless Steel Grades – Chemical Composition

Stainless steel is a family of iron-based alloys that contain a minimum of roughly 11 percent chromium, which produces a surface oxide layer that protects against degradation. Specific performance characteristics vary by grade, but the material offers an array of benefits.
