A 1.18 inch ss304 welded wire mesh panel is a rigid, flat panel made by resistance-welding stainless steel wires at approximately 1.18-inch (30 mm) intervals. The wires are typically made from AISI 304 stainless steel, which provides corrosion resistance, strength, and a clean appearance. In practical business applications, this panel is used for machine guarding, storage cages, animal enclosures, partitions, ventilation screens, and architectural infill. A correctly specified 30mm SS304 welded mesh panel helps companies improve safety, reduce maintenance, and achieve long service life in humid, hygienic, or corrosive environments.
The 1.18-inch measurement normally refers to a nominal mesh opening of approximately 30 mm. The exact conversion is 1.18 inches × 25.4 = 29.972 mm, so manufacturers and buyers commonly describe this specification as a 30mm SS304 welded mesh panel.
Unlike woven mesh, welded wire mesh is manufactured by placing longitudinal and transverse wires in a square or rectangular grid and joining them at every intersection through electric resistance welding. This produces a self-supporting panel with consistent openings and high dimensional stability.
SS304, also called AISI 304 or 18-8 stainless steel, is an austenitic stainless steel grade containing chromium and nickel. Its principal advantages include:
SS304 is not the same as SS316. For continuous exposure to seawater, concentrated chlorides, or aggressive chemical solutions, SS316 or another higher-alloy material may be more appropriate.
Wire mesh was historically produced by weaving wires together. Although woven mesh remains useful for filtration and fine screening, welded mesh became increasingly important as factories, warehouses, farms, and construction sites required stronger and more rigid panels.
Resistance welding allows manufacturers to control the mesh aperture, wire diameter, panel size, and weld pattern more consistently. Stainless steel then added corrosion resistance for food processing, pharmaceutical production, water treatment, and outdoor installations.
Modern production typically combines automated welding lines, calibrated wire-drawing equipment, panel straightening, cutting, and surface inspection. A professional manufacturer such as shunqiang can help buyers select wire diameter, panel dimensions, edge treatment, and grade according to the operating environment rather than relying only on the opening size.
The most common industrial application is perimeter guarding around machinery, conveyors, robotic cells, and automated production lines. The 30 mm opening provides visibility for operators while creating a physical barrier against accidental contact with moving components.
A 30mm SS304 welded mesh panel is particularly useful where the guard must remain rigid and corrosion-resistant. Panels can be installed in modular frames with swing gates, access doors, interlocking switches, and powder-coated or stainless-steel posts.
Businesses use stainless welded panels to create lockable inventory cages, tool rooms, pallet partitions, and high-value goods enclosures. The rigid grid discourages unauthorized access while allowing light, airflow, and visual inspection.
For warehouse projects, specify:
SS304 welded mesh is frequently selected for food-production partitions, ingredient storage, equipment platforms, drying racks, baskets, and protective screens. Its non-porous stainless surface is easier to clean than painted carbon steel, provided the welds are smooth and the design avoids dirt traps.
However, mesh alone does not automatically make an installation hygienic. The complete assembly should be designed for washdown, drainage, inspection, and sanitation. In highly chlorinated or acidic cleaning environments, the purchaser should review whether SS316 is required.
The 30 mm opening is suitable for many poultry, small-animal, laboratory, and agricultural enclosure designs. It offers ventilation and visibility while maintaining a firm structure.
The correct wire diameter depends on the animal, enclosure size, impact risk, and local welfare requirements. Edges should be trimmed, folded, or framed so that exposed wire ends do not cause injury.
Architects and mechanical contractors use stainless welded mesh for ventilation openings, equipment screens, façade infill, stair balustrade inserts, ceiling service zones, and air-conditioning enclosures. The open area permits airflow while preventing the passage of larger objects and reducing unauthorized access.
SS304 panels may be used for pump guards, walkway barriers, drainage-area screens, equipment cages, and protective covers. In ordinary outdoor conditions, stainless steel can provide a longer service life than galvanized mesh. In marine locations, however, chloride exposure can cause pitting corrosion, so SS316, duplex stainless steel, or a specialized coating may be necessary.
Before ordering a 30mm SS304 welded mesh panel, confirm the complete specification rather than purchasing by aperture alone.
| Parameter | Typical requirement | Why it matters |
|---|---|---|
| Material | AISI 304 / EN 1.4301 stainless steel | Determines corrosion resistance and weldability |
| Opening | Approximately 30 mm or 1.18 inch | Controls visibility, airflow, and access restriction |
| Wire diameter | Project-specific, for example 2.0–4.0 mm | Influences rigidity, impact resistance, and weight |
| Panel size | Cut-to-size or standard stock dimensions | Affects framing, transport, and installation labor |
| Surface | Mill finish, bright finish, or polished finish | Determines appearance and cleaning requirements |
| Edges | Cut edge, deburred edge, folded edge, or framed edge | Reduces handling hazards and improves installation |
For quality assurance, buyers should request material traceability and inspection records. Relevant references may include ASTM A580/A580M for stainless steel wire, EN 10204 for inspection documents, and ISO 4783-1 for industrial wire-screen aperture and wire-diameter considerations. If the panels are part of a structural reinforcement system, the applicable project standard may instead include ASTM A1064/A1064M or a local welded-wire reinforcement specification. The correct standard depends on the application, not simply on the word “welded.”
When sourcing from shunqiang, provide a technical inquiry that includes the mesh opening, stainless grade, wire diameter, panel dimensions, quantity, edge style, and intended use. A reliable supplier should be able to clarify whether the requested 1.18-inch opening is measured center-to-center or as the clear opening between wires.
For evidence-based purchasing, ask for:
Claims such as “100% inspection” should be supported by an inspection plan or report showing what was checked: wire diameter, aperture, panel length, width, flatness, weld appearance, and quantity. This approach provides stronger evidence than relying on a general product description.
It does not. The mathematical conversion is approximately 29.97 mm. Commercial mesh is often labeled 30 mm, but the buyer should confirm the permitted tolerance and the measurement method in the drawing or purchase order.
Stainless steel is corrosion-resistant, not corrosion-immune. Salt deposits, stagnant water, welding heat tint, iron contamination, and harsh chemicals can initiate staining or pitting. Proper passivation, cleaning, drainage, and material selection remain important.
Panel strength depends on wire diameter, weld quality, unsupported span, frame design, fixing points, and applied load. A 30 mm opening with a heavier wire may be stronger than a smaller opening made from very thin wire.
Machine guarding must comply with the risk assessment and applicable safety requirements. The opening size, reach distance, panel deflection, gate interlocking, and mounting structure must be evaluated as a complete guarding system.
They are not equivalent. Galvanized steel normally offers a zinc coating over carbon steel, while SS304 is a solid stainless-steel material. The two options differ in corrosion behavior, appearance, weldability, price, and maintenance requirements.
A food manufacturer needs a washable barrier around a conveyor motor area. The company selects SS304 welded panels with a 30 mm opening, stainless posts, and a framed access gate. The open grid maintains visibility and ventilation, while the stainless surface supports routine cleaning. The project specification includes smooth welds, deburred edges, EN 10204 material documentation, and inspection of every delivered panel for visible defects.
A distribution center uses a 30mm SS304 welded mesh panel to build a lockable cage for electronic components. The engineer chooses a heavier wire diameter, reinforced corner posts, floor anchors, and a steel frame. The 30 mm grid allows inventory to be seen without opening the cage, helping reduce stock-control time.
A water-treatment contractor initially considers SS304 for an outdoor pump enclosure. Because the site is exposed to salt-laden air, the contractor compares SS304 with SS316 and requests a corrosion-risk review. The final selection is based on chloride exposure, cleaning chemicals, expected service life, and total lifecycle cost—not only the initial panel price.
Use the following checklist before requesting a quotation for a 30mm SS304 welded mesh panel:
A 1.18 inch SS304 welded wire mesh panel is a rigid stainless-steel grid with a nominal 30 mm opening. Its main value comes from the combination of corrosion resistance, visibility, airflow, cleanability, and structural stability. It is widely used for machine guards, warehouse cages, partitions, hygienic areas, animal enclosures, ventilation screens, and outdoor equipment protection.
The best result depends on more than the aperture. Wire diameter, weld quality, panel tolerance, edge treatment, mounting design, environmental exposure, and applicable standards must all be verified. If your project requires a dependable 30mm SS304 welded mesh panel, prepare a complete technical specification and consult shunqiang for material documentation, dimensional control, inspection evidence, and application-specific guidance.
