A 1.18 inch SS304 welded wire mesh panel is a stainless steel grid with welded wire intersections and a nominal mesh opening described as 1.18 inches. That opening converts to approximately 29.97 mm, or about 30 mm; however, buyers should confirm whether the stated measurement means clear opening or center-to-center spacing. The opening alone does not define the panel: wire diameter, panel dimensions, edge finish, tolerances, and quantity also affect fit and suitability. In this guide, I explain how to specify the product, assess applications, compare quotations, and prepare a clear inquiry for Shunqiang Wire Mesh.

This guide is for procurement teams, fabricators, equipment manufacturers, and project engineers sourcing stainless welded mesh panels for commercial or industrial use. It is particularly useful when a drawing, sample, or specification calls for a nominal 1.18 inch opening but leaves other product details open. Buyers comparing offers can also use it to check whether suppliers are quoting the same construction rather than products that only share a similar opening size.
The right panel depends on its job and operating environment, not just the mesh measurement. A panel used as a guard, partition, screen, or support may have different requirements for rigidity, finish, edge treatment, and corrosion exposure. Where safety or regulated performance is involved, confirm the design and applicable project requirements with the responsible engineer.
This product is made from stainless steel wires arranged in a grid and joined at their intersections. “SS304” identifies the requested stainless steel grade, while “welded wire mesh panel” describes the construction and panel format. The stated 1.18 inch measurement typically describes the mesh opening, but suppliers may interpret opening dimensions differently unless the measurement method is specified.
A clear opening is the open space between the inside edges of adjacent wires. Center-to-center spacing measures from the center of one wire to the center of the next, so it includes a portion of the wire diameter. These measurements are not interchangeable; ask the supplier to show the measurement method on a drawing or quotation. The conversion is 1 inch = 25.4 mm, making 1.18 inches approximately 29.97 mm.
A complete specification helps suppliers quote on a consistent basis and reduces the chance of a panel that does not fit the application. The opening size is only one parameter, and it does not establish wire thickness, panel size, or load capacity. If you are working from an existing assembly, provide a dimensioned drawing or a sample reference where possible.
| Specification | What to Confirm | Why It Matters |
|---|---|---|
| Material | SS304 grade description and any documentation required for your order | Confirms the requested material basis and how it will be identified in the quotation. |
| Mesh opening | 1.18 inch nominal; clear opening or center-to-center spacing | Affects the size of objects that can pass through the mesh and how the panel aligns with adjoining parts. |
| Wire diameter | Required diameter and any agreed tolerance | Influences mesh geometry, panel weight, and rigidity; it should be selected for the application. |
| Panel dimensions | Length, width, and dimensional tolerances | Determines whether panels fit frames, openings, or downstream fabrication requirements. |
| Edges and finish | Cut edge, finished edge, surface condition, and any handling requirements | Helps address installation, assembly, and handling needs. |
| Quantity and packing | Order quantity, packing method, labeling, and destination requirements | Allows suppliers to assess production planning and shipment preparation. |
SS304 welded panels may be considered for partitions, equipment guards, storage dividers, screening, ventilation enclosures, and fabrication components. The open grid can allow air and light to pass while providing a physical barrier, but the panel’s suitability depends on wire diameter, support spacing, fixing method, and expected loads. Buyers should verify those design factors rather than treating the mesh opening as a measure of strength.
Stainless steel is often selected where a metal mesh is preferred for its corrosion resistance and cleanable surface compared with some unprotected carbon steel products. SS304 is not a universal solution for every chemical or outdoor environment. Exposure to chlorides, aggressive cleaning agents, or other corrosive conditions can change material suitability, so consult the project’s material requirements and, where needed, a qualified materials specialist.
For screening or separation, compare the opening with the smallest item that must be retained and the level of airflow or visibility needed. For guards and partitions, consider access prevention, frame design, and whether the wire and mounting arrangement meet the required mechanical performance. When the panel will be cut, bent, or welded into an assembly, ask the fabricator or supplier to review the drawing before ordering.
You will get efficient and thoughtful service from Shunqiang Wire Mesh.
Pricing depends on the confirmed material and dimensions, wire diameter, order quantity, fabrication requirements, packaging, and shipping arrangements. A larger or heavier panel may have different material and handling costs than a smaller panel, but suppliers need the full specification to assess it. Request an itemized quotation that identifies the quoted construction and any assumptions.
Minimum order quantities and production schedules vary with supplier capacity, stock availability, customization, and order size. I recommend asking for the MOQ, sample availability, estimated production time, packing details, and shipment terms directly rather than relying on a general estimate. Confirm when the delivery schedule begins—for example, whether it is counted from order confirmation, drawing approval, or receipt of required payment.
A frequent mistake is ordering by opening size alone. Two panels may both be described as 1.18 inch mesh yet differ in wire diameter, panel dimensions, or the method used to measure the opening. Another risk is assuming that SS304 is suitable for every corrosive environment; the actual exposure and maintenance conditions should be reviewed before selection.
Buyers can also overlook edge condition, mounting requirements, or packing needs until installation or delivery. These details are easier to resolve when included in the initial RFQ and shown on the approved drawing. If any specification is uncertain, document the assumption and request supplier confirmation before placing the order.
At Shunqiang Wire Mesh, we can review your requested opening, material, panel dimensions, wire diameter, quantity, and fabrication details to prepare a quotation for your application. Sending a dimensioned drawing or a clear specification helps us assess the requested construction and identify information that needs confirmation. For custom requirements, please provide the intended use and operating environment as part of your inquiry.
Before approving an order, request written confirmation of the agreed specifications, price basis, MOQ, estimated lead time, packing method, and any documentation required for your procurement process. This gives both parties a shared reference for production and shipment planning. Availability and schedule should be confirmed against the details and quantity of each inquiry.
A 1.18 inch SS304 welded wire mesh panel is best specified as a complete product, not by opening size alone. Confirm that 1.18 inches means the intended opening measurement, then define wire diameter, panel dimensions, tolerances, edges, application, and environmental conditions. These steps make supplier quotations easier to compare and reduce avoidable fit or performance issues.
To move forward, prepare a drawing or RFQ with your required SS304 grade, approximately 29.97 mm nominal opening, wire diameter, panel size, quantity, and delivery destination. Share it with Shunqiang Wire Mesh to discuss the specification and request a project-specific quotation.
