Benefits of Stainless Steel Bar Grating

Boost the look and performance of your application with stainless steel bar grating products from Marco Specialty Steel. Stainless steel is ideal for use in caustic atmospheres where corrosion resistance and minimum carbide precipitation are important considerations. It is especially applicable for chemical, food, and hydro-processing areas. A durable, weather-resistant, and visually striking metal alloy, stainless steel expertly balances form and function.

  • Resists corrosion
  • High strength
  • Long cycle life
  • Low weight
  • Easy to clean
  • Recyclable
  • Stands up to extreme temperatures
  • Simple to sterilize
  • Shiny appearance
  • Good weldability
  • Strong formability
  • Resists magnetism, in some cases

    When subjected to impact forces, the surface oxide layer self-heals as long as there is Oxygen, even in small amounts. As a result, you get stainless steel bar grating that sustains nicks, marks, scratches, or other forms of damage that won’t corrode.

      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.

      Stainless Steel Grades

      We’re happy to create bar grating products using stainless steel. Letting us source the material saves you time and hassle, freeing you to focus on your core business. Our technicians can handle an array of stainless steel types.

      • Austenitic Stainless Steel – Contain a high percentage of nickel and chromium, which enhance its ability to be welded into any shape while providing resistance to corrosion and great strength.
      • Ferritic Stainless Steel – These are non-magnetic non-heat-treatable steels that have good heat and corrosion resistance and are not hardened by heat treatment, but are marginally hardenable by cold rolling.   
      • Duplex Stainless Steel – These are about twice as strong as regular austenitic or ferritic stainless steel. They are extremely corrosion resistant which is attributed to their chemical composition and balanced microstructure.
      • Martensitic Stainless Steel – Possess high corrosion resistance and its hardness levels are among the highest of all the stainless steel grades. These grades are magnetic and can be hardened by heat treatment.
