A 1.18 inch SS304 welded wire mesh panel is a rigid wire grid made by resistance-welding stainless steel wires at intersections, with approximately 1.18 inches between adjacent wires in one direction or both directions, depending on the drawing. SS304 provides a widely used austenitic stainless steel option for general corrosion resistance, cleanability, and fabrication. For accurate purchasing, I recommend confirming whether “1.18 inch” means the center-to-center opening, clear opening, or another dimensional reference before requesting a quotation.
This guide explains the specifications I would review, the applications that may suit this panel, and the questions I would ask a supplier before placing a B2B order. It also outlines practical issues such as wire diameter, panel size, tolerances, finish, quantity, packaging, and delivery planning.
This guide is intended for importers, distributors, fabricators, contractors, equipment manufacturers, and engineering teams sourcing stainless steel welded wire mesh panels. It is especially useful when the buyer needs a repeatable opening pattern rather than a flexible wire roll. It can also help procurement teams compare quotations that appear similar but use different definitions for opening size, wire diameter, or panel dimensions.
I recommend using this information as a purchasing framework rather than as a substitute for a project drawing or application-specific engineering review. Loads, temperature, chemical exposure, hygiene requirements, and local regulations can affect the correct material and construction.
Welded wire mesh panels are manufactured by arranging longitudinal and cross wires into a grid and joining the intersections by welding. The result is a flat, relatively rigid panel that can be cut, framed, folded, or installed as a barrier, screen, guard, rack component, or support element. The welding process creates fixed intersections, so the panel does not move like woven mesh.
In a 1.18 inch specification, the most important issue is dimensional terminology. A buyer should state whether the required measurement is the nominal wire-center spacing or the clear distance between wires, because wire diameter changes the clear opening. I advise including a sketch that shows opening direction, wire diameter, panel length, panel width, and the required tolerance.
SS304 is frequently selected for general-purpose stainless steel mesh because it combines corrosion resistance with practical formability and weldability. It may be suitable for indoor equipment, architectural components, food-related handling areas, ventilation guards, storage structures, and other environments where a clean metallic surface is preferred.
However, SS304 is not automatically suitable for every chemical or outdoor environment. Chloride-rich conditions, strong acids, high temperatures, marine exposure, or frequent chemical cleaning may require a different material assessment, potentially including another stainless steel grade or a protective design. I recommend asking the supplier to review the actual exposure instead of selecting material by grade name alone.
| Specification | What to Confirm | Why It Matters |
|---|---|---|
| Material | SS304, with the required material documentation if applicable | Material affects corrosion behavior, fabrication, and project acceptance |
| Opening | 1.18 inch nominal or clear opening; square or rectangular layout | Opening affects airflow, visibility, containment, and component fit |
| Wire diameter | Required diameter in millimeters or inches | Diameter influences rigidity, weight, weld area, and open area |
| Panel size | Length, width, flatness, and allowable dimensional tolerance | Panel size affects installation, shipping, cutting, and material utilization |
| Surface | Mill finish, bright finish, cleaned finish, or other agreed condition | Surface requirements influence appearance, cleaning, and handling |
| Edge treatment | Cut edge, trimmed edge, folded edge, or framed edge | Edges affect safety, assembly, and the need for secondary fabrication |
At a minimum, I would place the opening size, wire diameter, material, and panel dimensions on the purchase order. If the panel will be welded, bolted, or inserted into a frame, the connection detail should also be shown. A wire diameter of 3 mm, for example, is not interchangeable with a wire diameter of 5 mm simply because both panels have the same nominal opening.
Flat welded wire mesh panels are the usual starting point for general industrial and commercial applications. They can be supplied as individual sheets and may be cut to suit a frame, guard, partition, or fabrication assembly. Their suitability depends on the required rigidity, support spacing, impact exposure, and connection method.
Some projects need rectangular openings, unequal wire spacing, trimmed borders, folded edges, or special panel dimensions. These details should be treated as engineered specifications rather than assumed standard features. I recommend requesting a production drawing or sample approval when the panel must fit a prefabricated structure.
Surface treatment should also be discussed clearly. Stainless steel may be supplied with a standard mill appearance or with additional cleaning and finishing requirements, but the exact result depends on the manufacturing and handling process. A supplier should explain what is included in the quotation and what would be treated as an extra operation.

The 1.18 inch opening can be useful where a project needs a visible, ventilated, and relatively open grid. Potential uses include machine guards, equipment partitions, storage cages, shelving components, animal enclosures, architectural infill, ventilation screens, and general fabrication. The correct use depends on the wire diameter and support design, not on the opening size alone.
For food-processing or cleanable equipment areas, I would examine surface condition, weld consistency, edge safety, cleaning access, and the compatibility of SS304 with the cleaning chemicals. For machine guarding, I would additionally verify the required safety distance, impact resistance, access control, and the complete guard assembly. The mesh panel should not be evaluated independently from its frame, fasteners, and installation method.
Start by identifying what the panel must do: contain materials, prevent access, provide airflow, support stored items, protect equipment, or serve an architectural purpose. Record the expected load, span, exposure, and operating environment. This information allows the supplier to comment on whether the requested wire diameter and panel construction are reasonable.
Prepare a specification sheet with the material grade, opening definition, wire diameter, panel dimensions, quantity, edge condition, and finish. Use one unit system throughout the drawing, such as millimeters for wire diameter and panel size, while also listing the 1.18 inch reference if it is required by the project. Include a tolerance wherever fit or interchangeability matters.
When reviewing offers, compare the same material, opening reference, wire diameter, panel size, quantity, packaging method, and delivery term. A lower price may reflect a thinner wire, a different opening measurement, fewer finishing operations, or packaging that is less suitable for export handling. I recommend asking each supplier to confirm every line item in writing.
Before mass production, clarify how the supplier checks wire diameter, opening size, panel dimensions, weld appearance, flatness, and surface condition. If inspection documents or material records are required, state this before ordering. For customized panels, a sample or production drawing can reduce the risk of receiving a product that is technically similar but unsuitable for assembly.
Pricing for welded wire mesh panels normally depends on material consumption, wire diameter, panel dimensions, quantity, customization, finishing, packaging, and delivery destination. I avoid treating a price per panel as meaningful until these variables are fixed. Freight can also be important because rigid panels occupy more volume than compact rolls.
Minimum order quantity and lead time should be requested as project-specific information rather than assumed from a general catalog. Standard dimensions may be easier to schedule, while customized openings, special borders, or nonstandard panel sizes may require additional production planning. For urgent projects, ask whether the quoted lead time covers drawing approval, manufacturing, inspection, packing, and dispatch.
As a manufacturer and exporter of wire mesh products, Shunqiang Wire Mesh can review a buyer’s specification for 1.18 inch SS304 welded wire mesh panel and help organize the required material, opening, wire diameter, panel size, and packaging details. Our practical approach is to confirm the technical description before preparing a quotation, especially when the opening terminology or panel configuration is not standard. Availability, MOQ, lead time, documentation, and customization should be confirmed for each order.
The best way to source a 1.18 inch SS304 welded wire mesh panel is to define the opening reference, wire diameter, panel dimensions, material, edge treatment, and operating environment before comparing prices. This approach helps ensure that different suppliers are quoting the same product and makes technical review more reliable. It also gives the supplier enough information to identify potential limitations before production.
To begin, prepare your panel drawing or quantity list and state whether the 1.18 inch dimension is a clear or nominal opening. Then share the required SS304 grade, wire diameter, panel size, finish, application, destination, and target schedule with Shunqiang Wire Mesh. We can use those details to review the specification and prepare a project-specific quotation for your B2B purchasing decision.
