A 1.18 inch SS304 welded wire mesh panel is a grid of stainless steel wires joined at their intersections, with a nominal opening of 1.18 inches (approximately 29.97 mm). It is commonly considered when buyers need a rigid, open panel for separation, guarding, screening, or fabrication in environments where corrosion resistance matters. The opening alone does not define a complete specification: wire diameter, panel dimensions, edge finish, and the intended environment also affect suitability. In this guide, we explain how to specify the mesh, match it to an application, and evaluate a supplier before requesting a quotation.

This guide is for procurement teams, fabricators, equipment manufacturers, and project engineers sourcing stainless steel welded mesh panels. It is particularly useful if a drawing or existing design calls for a 1.18 inch opening but leaves other details open. We recommend confirming those details before comparing quotations, since panels with the same opening may differ in strength, weight, finish, and fit. Buyers should treat the guidance below as a specification framework, not as confirmation of a standard stock size or a particular performance rating.
The stated 1.18 inch measurement may refer to the clear opening between wires, but buyers should not assume that without checking the drawing or supplier’s quotation. Clear opening is measured from the inside edge of one wire to the inside edge of the next. Pitch, by contrast, is the center-to-center distance between adjacent wires and includes the wire diameter. This difference affects the number of openings across a panel and can change how well the mesh fits a frame or performs as a screen.
For reference, 1.18 inches converts to approximately 29.97 mm. If the specified opening is a clear opening, the pitch will be larger than 29.97 mm by the wire diameter in that direction. Ask the supplier to state whether the aperture is nominal or clear, and whether both directions use the same opening and wire size. A dimensioned drawing can resolve ambiguity before production begins.
SS304 identifies the stainless steel grade requested for the wires. The wires are arranged in a grid and joined at their crossings to form a panel. The finished panel’s behavior depends on the selected wire diameter, panel dimensions, weld quality, and how it is supported or fixed in the final assembly. A material designation by itself does not establish a load rating, corrosion life, or suitability for every chemical environment.
Stainless steel 304 is commonly considered for general indoor and outdoor applications where stainless corrosion resistance is useful. Exposure conditions still matter: chlorides, cleaning chemicals, temperature, moisture, and crevices can influence corrosion behavior. If the panel will contact aggressive chemicals or be used near saltwater, discuss the environment with your technical team and ask whether another grade should be evaluated.
A relatively large opening can be appropriate when the goal is to create a visible, open barrier rather than a fine filter. Possible uses include machine or equipment guarding, partition panels, storage cages, protective covers, and fabricated frames. It may also suit screening tasks where the material being separated is larger than the opening and a coarse grid is acceptable. Final suitability depends on the equipment, local safety requirements, and the way the panel is installed.
Do not select this mesh solely because the opening appears close to the size of the material being screened. Particle shape, orientation, vibration, and the chance of clogging can affect separation. For safety guarding, check the complete assembly—including frame openings, attachment points, and reach-through risk—against applicable project requirements. A mesh panel should not be treated as a certified safety system unless the relevant design and compliance requirements have been assessed.
If the application requires fine filtration, a 1.18 inch opening may be too large. A smaller aperture or a different screening medium may be needed, depending on the target particle size and process conditions. If the panel needs to span a wide unsupported area or carry a defined load, the wire diameter, frame, support spacing, and fixing method need engineering review. We advise sharing the functional requirement rather than asking a supplier to infer performance from the opening size alone.
With competitive price and timely delivery, Shunqiang Wire Mesh sincerely hope to be your supplier and partner.
Before requesting a quote, prepare a specification that covers the following points. Mark which values are fixed and which may be proposed by the supplier. If a project drawing is available, attach it and ask the supplier to identify any assumptions before production.
A low price is difficult to evaluate if suppliers are quoting different wire diameters, panel sizes, or edge treatments. Ask each supplier to list the material grade, opening definition, wire diameter, dimensions, tolerances, and packing assumptions in writing. Request clarification on whether any proposed substitution changes the design or requires customer approval. This makes the commercial comparison more useful and reduces the risk of receiving a panel that does not fit the intended assembly.
| Specification item | What to confirm | Why it matters |
|---|---|---|
| Opening | Clear opening or pitch; measurement direction | Affects fit, open area, and screening behavior |
| Wire diameter | Exact value and tolerance | Influences rigidity, weight, and panel construction |
| Panel size | Length, width, quantity, and tolerances | Determines fit, handling, and fabrication requirements |
| Material and finish | SS304 confirmation and requested surface condition | Helps align the supplied panel with the environment and project documents |
The cost of a welded mesh panel depends on the confirmed material, wire diameter, panel dimensions, quantity, finishing, and packing requirements. Custom cutting or fabrication may also affect the quotation. Because these variables are project-specific, there is no reliable single price that applies to every 1.18 inch SS304 panel. Send a complete specification and ask the supplier to itemize the assumptions behind the offer.
Minimum order quantity and lead time should likewise be confirmed for the exact configuration. They can vary with production planning, raw material availability, quantity, and any custom work. When timing is important, provide the required delivery date and destination at the enquiry stage, then request confirmation of production and shipping estimates. Do not treat an indicative estimate as a confirmed commitment until it appears in the supplier’s order documentation.
A capable supplier should be able to discuss the specification clearly and identify missing information rather than simply quote an ambiguous description. Ask how the opening is measured, how the wire diameter and panel dimensions will be recorded, and what inspection details are available for the order. If documentation is important to your project, state the required documents before ordering and confirm whether they can be provided for the quoted material. Review samples or drawings when appropriate, especially when the panel must fit an existing frame.
At Shunqiang Wire Mesh, we help B2B buyers turn a general mesh requirement into a clearer purchasing specification. When you enquire about a 1.18 inch SS304 welded wire mesh panel, include the opening definition, wire diameter if known, panel dimensions, quantity, intended use, and destination. If some details are undecided, tell us which requirements are fixed and where you are open to recommendations. We can review the information with you and confirm the available configuration, quotation basis, and order details for your project.
A 1.18 inch SS304 welded wire mesh panel is a welded stainless grid with a nominal opening of about 29.97 mm, but that opening alone is not a complete buying specification. Confirm whether it means clear aperture or pitch, then define wire diameter, panel dimensions, finish, edges, quantity, and service environment. Check application-specific requirements separately, particularly for filtration, structural loading, and safety guarding. These steps make supplier quotations easier to compare and help reduce fit or performance misunderstandings.
To request a quotation from Shunqiang Wire Mesh, send your drawing or a written specification with the required quantity and delivery destination. We can then review the details, clarify open questions, and provide a quote for evaluation. If you do not yet know the appropriate wire diameter or panel configuration, share the operating conditions and intended function so the options can be discussed before you place an order.
