Stainless Steel

Stainless steels are iron alloys with a minimum of 10.5% chromium. The rust resistance combined with Stainless Steel’s resistance to high and low temperatures means that it can be used for a very broad variety of applications where hygiene and sterilisation are required.

All Stainless Steel has a high resistance to corrosion. Low alloyed grades (Grade 304) resist corrosion in atmospheric conditions; highly alloyed grades (Grade 316, Marine Grade) can resist corrosion in most acids, alkaline solutions and chloride bearing environments.

Fabrication Methods

Stainless Steel can be cut, shaped and joined using:

  • TIG Welding
  • Press brake bending
  • Punching
  • Sheared and sawn


Duffys offer a range of finishes for stainless steel including:

  • Brushed or Satin finish
  • Electropolished finish
  • Mirror polished finish


Stainless Steel is often used in the pharmaceutical, agricultural and catering sectors for its corrosion resistance, cleanliness and durability.

The aesthetic appeal of Stainless Steel makes it a very popular choice for many in domestic and commercial applications. It maintains a fresh, clean long term appearance, lasting years.

Stainless Steel grade 304 is used to manufacture:

  • Staircase handrails
  • Kitchen and canteen furniture
  • Machine parts
  • Cabinets and shelving
  • Tables, trolleys and racks
Stainless Steel grade 316 is used to manufacture:

  • Boat fittings and structural members
  • Architectural components
  • Food and beverage processing equipment
  • Hot water systems
  • Plant for chemical, petrochemical, mineral processing
