A 1.18 inch SS304 welded wire mesh panel is a stainless steel panel made by welding intersecting wires into a grid, with a nominal opening of 1.18 inches (approximately 30 mm). It can suit applications that need a rigid, open grid and the corrosion resistance associated with 304 stainless steel, provided the environment is appropriate for that grade. The opening alone does not define the panel: wire diameter, panel dimensions, edge finish, and tolerances also affect fit and performance. We recommend confirming these details with your supplier before requesting a quotation or placing an order.

This guide is for purchasing teams, fabricators, project engineers, and distributors sourcing welded wire mesh panels for commercial or industrial use. It is especially useful when a drawing or project description specifies a 1.18 inch opening but leaves other details open. Our aim is to help you turn that brief description into a quote-ready specification. The final requirements should still be checked against your application and any governing project documents.
Welded wire mesh consists of longitudinal and transverse wires joined at their intersections to form a grid. In an SS304 panel, the wires are specified as 304 stainless steel, while “1.18 inch” describes the stated mesh opening unless the buyer defines it differently. The converted metric value is approximately 29.97 mm, commonly rounded to 30 mm for specification purposes. Because suppliers may describe opening size as clear distance or as wire center-to-center spacing, buyers should state which measurement they require.
The opening is only one part of the grid geometry. Wire diameter affects the open area, panel rigidity, weight, and the overall dimensions of the finished mesh. Two panels with the same nominal opening can therefore differ substantially if their wire diameters or measurement conventions are different. Ask the supplier to confirm the opening definition and list the wire diameter separately in the quotation and order documents.
SS304 is often selected for its combination of stainless steel properties and broad availability. Its suitability is not universal: exposure to chlorides, chemicals, moisture, temperature changes, and cleaning agents can influence material selection and service life. For severe or specialized environments, consult a qualified materials professional and compare the required grade with the actual operating conditions. Do not treat “stainless steel” as a guarantee of corrosion-free performance in every setting.
| Specification | What to state or confirm |
|---|---|
| Material | SS304; state any required material documentation or traceability expectations. |
| Opening | 1.18 inch (approximately 30 mm); clarify clear opening or center-to-center measurement. |
| Wire diameter | Provide the required diameter and unit, or request options based on the application. |
| Panel size | Specify finished width and length, plus any dimensional tolerance required. |
| Finish | Describe the required surface condition and any post-weld cleaning or finishing needs. |
| Edges and packaging | State whether edges should be cut, framed, or otherwise treated, and describe shipment protection. |
These details are not implied by the phrase “1.18 inch SS304 welded wire mesh panel.” For example, panel dimensions may be project-specific rather than a universal standard size, and wire diameter should not be assumed from the opening. Finish requirements can also differ depending on whether the panel is used as a screen, partition, guard, or fabricated component. A clear written specification reduces the risk of comparing quotations for products that are not equivalent.
A roughly 30 mm grid may be considered for partitions, protective barriers, racks, guards, screening, or fabricated assemblies where the open structure is appropriate. The right choice depends on what the panel must retain, support, shield, or allow through. The opening size by itself does not establish load capacity, safety performance, or suitability as a machine guard. For structural or safety-critical uses, provide the design loads and applicable requirements to a qualified engineer or project authority.
Start with the panel’s function and the conditions it will encounter. Note whether it will be exposed to weather, washdown, chemical contact, impact, vibration, or sustained loading. These details help a supplier discuss appropriate material and construction options without guessing at the intended use. If the panel is part of a regulated or engineered system, include the relevant project specification in your inquiry.
Shunqiang Wire Mesh supply professional and honest service.
Provide the opening, wire diameter, panel width, panel length, and required tolerances. State units consistently, and attach a drawing when the panel includes cutouts, special edges, or a frame. If your design uses 1.18 inch as a clear opening, write that explicitly rather than relying on a product name. Ask the supplier to confirm dimensions in writing before production.
Confirm that the quoted product is welded mesh rather than woven mesh or another grid construction. Discuss the weld condition, edge treatment, and requested surface finish, particularly if the panel will be handled, fitted to a frame, or cleaned frequently. Any finishing step should be described in the order rather than assumed. Request product photographs, drawings, or a sample when these would help verify the specified appearance or construction.
Price can depend on material, wire diameter, panel dimensions, order quantity, finishing, packing, and delivery destination. Minimum order quantity and lead time are supplier- and order-specific, so request current figures rather than relying on general market estimates. For a fair comparison, ask each supplier to quote the same specification and clarify whether packaging and freight are included. Confirm payment, inspection, and shipment terms before issuing a purchase order.
A reliable sourcing decision involves more than comparing unit prices. Ask the supplier to confirm the stated grade, mesh opening, wire diameter, panel size, tolerances, finish, and packing method. If documentation is needed, specify the exact document and its required format before ordering; availability should be confirmed rather than presumed. You can also ask how changes, dimensional questions, or production issues are communicated during the order process.
One frequent mistake is specifying the opening but omitting wire diameter, which can lead to non-comparable quotations. Another is assuming SS304 will suit every chemical or outdoor environment without checking exposure conditions. Buyers may also overlook edge treatment, panel tolerances, or the distinction between clear opening and wire spacing. Resolve these points in the quotation stage, when changes are easier to document.
At Shunqiang Wire Mesh, we supply wire mesh products and can review your required opening, material, wire diameter, panel size, finish, and order quantity for a quotation. To help us assess the request, send a drawing or specification sheet along with the intended application and delivery destination. We can then confirm which details are available for the order and identify any points that need clarification. Final manufacturing scope, documentation, quantity, and schedule should be agreed in the written quotation.
A 1.18 inch SS304 welded wire mesh panel is defined by more than its nominal opening: material, wire diameter, panel dimensions, finish, edge treatment, and tolerances all matter. Start by confirming that 1.18 inch means the required opening measurement, then match the panel construction to the application and operating environment. Request comparable written quotations that state commercial terms, production timing, and any required documentation. Send your drawing or complete specification to Shunqiang Wire Mesh to discuss the appropriate options for your project.
