A 1.18 inch SS304 welded wire mesh panel is a rigid grid made by welding stainless steel wires at regular intersections, with “1.18 inch” identifying the specified mesh opening or spacing. That dimension is approximately 29.97 mm, commonly rounded to 30 mm, but buyers should confirm whether the measurement means clear opening or wire-center spacing. The opening alone does not define the complete product: wire diameter, panel size, edge finish, tolerances, and grade documentation also need to be agreed before ordering.

This guide is for industrial buyers, fabricators, project engineers, and distributors comparing specifications or preparing a supplier inquiry. We explain what to confirm, where this panel may be suitable, and how to evaluate a quotation without assuming that one configuration fits every project. Shunqiang Wire Mesh can review application requirements and discuss available production options when you provide a drawing or a clear specification.
This guide is intended for buyers sourcing welded stainless steel mesh panels for equipment, fabrication, screening, partitions, or general industrial use. It is also useful when a project specification lists a 1.18 inch opening but omits other dimensions needed for manufacturing. If you are buying for a regulated or safety-critical installation, treat this information as a procurement starting point and verify the final design against applicable project requirements.
The panel consists of longitudinal and transverse wires joined at their crossing points by welding. The welded intersections create a fixed grid, while the wire diameter and opening pattern influence rigidity, open area, weight, and the size of material that can pass through. Unlike woven mesh, the wires are arranged in a regular welded pattern rather than interlaced over and under one another.
SS304 identifies the stainless steel grade requested for the wire, subject to confirmation in the order documents. It is commonly selected for general-purpose corrosion resistance, cleanability, and fabrication needs, but it is not suitable for every chemical or outdoor environment. In particular, exposure to chlorides, aggressive chemicals, elevated temperatures, or frequent washdown may require a corrosion review and possibly another material grade.
State whether the 1.18 inch dimension is the clear distance between adjacent wire surfaces or the pitch measured from the center of one wire to the center of the next. These definitions produce different usable openings when wire diameter changes. For reference, 1.18 inches converts to approximately 29.97 mm; using “30 mm nominal” in a purchase document should not replace confirmation of the actual measurement convention and tolerance.
Wire diameter affects panel stiffness, weight, and open area, so it should be selected for the application rather than inferred from the opening. As initial discussion examples only, buyers might ask a supplier to assess 1.6 mm, 2.0 mm, or 3.0 mm wire; these are not default specifications or a claim that every combination is available. Request confirmation of the offered diameter, dimensional tolerance, and whether the stated value is measured before or after processing.
Provide the required panel width and length, along with any cutouts, notches, bent edges, frames, or connection details. Also state whether cut edges may remain exposed, need deburring, or require another finish. Panel dimensions and edge treatments can affect handling, installation, and the final quotation.
Ask the supplier to identify the tolerances that apply to opening, wire diameter, overall dimensions, and squareness. If panels must fit into a frame or align with adjacent sections, provide the mating dimensions and installation method. A drawing with clearly marked units and measurement references can reduce ambiguity during production and inspection.
A 1.18 inch opening may suit applications where a relatively open grid is required and the target material or object is larger than the aperture. Potential uses include equipment guards, partitions, storage or display structures, protective barriers, and selected screening or fabrication projects. Suitability depends on load, impact risk, particle dimensions, support spacing, and local safety requirements rather than opening size alone.

For screening, compare the aperture with the smallest particle that must be retained and account for particle shape, orientation, and operating conditions. For a guard or partition, evaluate wire thickness, panel span, fixing points, and the possibility of impact or deflection. For a washdown or corrosive setting, confirm that SS304 is appropriate for the actual chemicals and concentration; do not assume that stainless steel is immune to corrosion.
| Buyer Requirement | Specification to Clarify | Why It Matters |
|---|---|---|
| Screening or separation | Clear aperture, wire diameter, and tolerance | Defines what can pass through the grid and how repeatable the opening needs to be. |
| Guarding or partitioning | Panel dimensions, support spacing, edge finish, and fixing method | Helps the fabricator assess fit, handling, and structural requirements. |
| Corrosive or washdown exposure | SS304 confirmation and service-environment details | Allows the grade choice to be reviewed against actual exposure conditions. |
The cost of a welded wire mesh panel depends on the agreed material, wire diameter, opening, panel size, order quantity, finishing or fabrication work, packaging, and delivery terms. Because these variables differ by order, a reliable price should be based on a defined specification rather than the phrase “1.18 inch SS304 mesh” alone. Ask the supplier to itemize any optional cutting, framing, or special packing so that quotations can be compared consistently.
Minimum order quantity and production lead time are supplier- and order-specific. Custom panel dimensions, nonstandard tolerances, finishing, and material availability can affect the schedule, so request a current estimate for the precise configuration and destination. For project planning, confirm whether the quoted lead time begins after drawing approval, deposit, or another agreed milestone.
Clear answers help buyers distinguish a product that merely matches the nominal opening from one that matches the full project requirement. If a supplier cannot confirm a critical dimension or material detail, resolve it in writing before placing an order. For custom or safety-sensitive applications, have the responsible project engineer approve the final specification.
A frequent mistake is specifying only “1.18 inch mesh” without defining how the opening is measured. Another is selecting wire diameter solely by appearance or assuming a particular thickness is standard for every panel. Buyers should also avoid treating SS304 as universally corrosion-proof, especially when service conditions include salt, chlorides, or aggressive cleaning agents.
In addition, do not compare prices unless the quoted panels share the same material, dimensions, tolerances, edge requirements, and packing basis. An apparently lower price may exclude cutting, inspection, or delivery requirements that another offer includes. A complete, aligned specification makes both technical review and commercial comparison more useful.
Shunqiang Wire Mesh supports B2B inquiries for welded wire mesh by reviewing requested material, opening, wire diameter, panel size, and finishing details. To help us assess a 1.18 inch SS304 panel request, send a drawing or list the measurement convention, tolerances, application, quantity, destination, and target delivery schedule. We can then discuss the configuration and quotation information needed for your purchasing review.
A 1.18 inch SS304 welded wire mesh panel is defined by more than its nominal opening: buyers also need to confirm how that opening is measured, the wire diameter, panel dimensions, tolerances, edge treatment, and service environment. The nominal opening equals approximately 29.97 mm, or 30 mm rounded, but the purchase specification should state the required measurement method explicitly. SS304 may suit many general-purpose applications, while exposure conditions and project requirements still need review.
Your next step is to prepare a drawing or specification covering the application, opening definition, wire diameter, panel size, finish, quantity, and delivery destination. Use the same details when requesting quotations, and obtain written confirmation of any critical dimensions and material documentation. Contact Shunqiang Wire Mesh with these requirements to discuss a suitable panel configuration and request a project-specific quotation.
