Light-Duty Stainless Steel Grating is a corrosion-resistant, hygienic flooring solution made from AISI 304, 304L, 316, or 316L alloys. It features welded construction with rectangular or serrated bearing bars (20–40 mm deep, 3–5 mm thick) and twisted square or round cross bars (spaced 50–120 mm), supporting 2–15 kN/m² for pedestrian and light equipment traffic. Panels (up to 3000×6000 mm) offer mill, brushed, polished, or electro-polished finishes for enhanced durability, easy cleaning, and slip resistance in wet or chemical environments.
Stainless steel – Lightweight steel grating
Light-Duty Stainless Steel Grating
1. Product Overview
Light-duty stainless steel grating combines corrosion resistance with light structural load capacity. Constructed from AISI 304 or 316/316L alloys, welded into an open mesh configuration, it is ideal for pedestrian walkways, light equipment platforms, chemical or food processing areas, and offshore access zones. Panels resist corrosion, allow drainage, and maintain hygiene while remaining structurally stable for light-duty traffic.

8. FAQ
Q: Is 316L necessary for all outdoor applications?
A: 316L is recommended for areas within 5 km of the sea; 304 is typically sufficient for inland chemical or light-duty industrial applications.
Q: Can light-duty stainless steel panels handle light equipment carts?
A: Yes, bearing bar thickness and spacing are designed to meet pedestrian and light equipment load requirements while ensuring deflection safety.
In summary, Light-Duty Stainless Steel Grating provides reliable, low-maintenance performance in corrosive and hygiene-critical settings such as food processing, chemical plants, water treatment facilities, offshore platforms, and light industrial walkways. Its lightweight open-grid design ensures excellent drainage, ventilation, and safety while customizable cuts and finishes meet precise project needs with long-term corrosion resistance.
