Stainless Steel Perforated Metal Sheets
Benefits of Perforated Stainless Steel
A durable, weather-resistant, and visually striking metal alloy, stainless steel expertly balances form and function. Boost the look and performance of your application with stainless steel perforated metal products from Marco Specialty Steel.
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.
- 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, stainless steel perforated sheet that sustains nicks, marks, scratches, or other forms of damage won’t corrode.

Stainless Steel Grades
We’re happy to create perforated 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. These grades are magnetic and can be hardened by heat treatment.
