WS stainless steel grating (SUS304 / SUS316)

Why stainless

Stainless steel grating needs no coating, cleans easily and resists corrosion where galvanised steel would be attacked – food and beverage, dairy, pharmaceutical, chemical plants, water and wastewater treatment, coastal and marine structures. SUS304 suits most hygienic and indoor uses; SUS316, with molybdenum, is chosen for chlorides, sea water and aggressive chemicals.

Fabrication

• Separate tools and storage from carbon steel to prevent iron contamination.
• Welded with matching stainless filler; heat tint removed by pickling.
• Passivated and rinsed; surface finish agreed for hygienic areas.
• Fasteners and clips in stainless steel of the same or better grade.

Load capacity is similar to carbon steel grating of the same size for selection purposes; final design uses the stainless steel properties of the project code (for example AISC Design Guide 27, AS/NZS 4673 or EN 1993-1-4).
