304 Stainless Steel welded wire mesh panels combines the construction of welded wire mesh panels (EN 10223-7 / ASTM A740) with the properties of AISI 304 (1.4301): good general corrosion resistance in atmosphere and fresh water, essentially non-magnetic (annealed), service to approx. +450 °C continuous. This page summarizes the grade data, its behavior in filtration service, comparable alloys, and the specifications supplied.
Why Choose 304 Stainless Steel for Welded Wire Mesh Panels
The standard general-purpose stainless mesh alloy. For welded wire mesh panels, this matters when good general corrosion resistance in atmosphere and fresh water is the controlling requirement.
Alloy Properties
| Grade designation | AISI 304 (1.4301) |
|---|---|
| Magnetic response | Essentially non-magnetic (annealed) |
| Service temperature | approx. +450 °C continuous |
| Corrosion characteristic | Good general corrosion resistance in atmosphere and fresh water |
Corrosion Behavior in Filtration Service
304 gives good resistance to atmospheric exposure, fresh water and most neutral media, and is the standard general-purpose grade for welded wire mesh panels. In chloride-bearing service (seawater, brines, road-salt spray) step up to 316L; in reducing acids consider a nickel alloy.
Comparable Alloys
The direct upgrade from 304 is 316L (chlorides, acids, CIP). Downgrade options for dry, indoor screening are galvanized or plain steel. For heat beyond ~450 °C move to Inconel 600; for seawater immersion consider Monel 400 or duplex 2205 for welded wire mesh panels.

Where 304 Stainless Steel Welded Wire Mesh Panels Is Used
- Machine guarding & partitions: heavy duty welded wire panels in modular guard systems.
- Food & pharmaceutical plants: stainless steel welded wire mesh shelving, racks and trays.
- Warehousing: rack decking and security partitions.
- OEM fabrication: welded mesh panels built into equipment frames.
Ordering Welded Wire Mesh Panels in 304 Stainless Steel
- Opening & wire: Square or rectangular opening and wire gauge sized for load and containment.
- Panel size: Standard 4 × 8 ft or cut to drawing with trimmed or selvedge edges.
- Finish: Stainless 304/316, galvanized after welding, or powder coated.
Mistakes to Avoid with Welded Wire Mesh Panels
- Using bare carbon steel panels outdoors, which rust at every weld.
- Choosing a wire gauge too light for shelving or guard impact loads.
