1/4 inch SS201 welded wire mesh is made by welding stainless steel wires at their crossing points to form a regular grid with nominal openings of 1/4 inch, or 6.35 mm. It can suit applications that need a relatively fine, rigid mesh and where SS201’s material characteristics match the service environment. The opening size alone is not enough to confirm suitability: wire diameter, mesh dimensions, finish, fabrication, and exposure conditions also matter. At Shunqiang Wire Mesh, we recommend confirming these details before requesting a production quote.

This guide is for procurement teams, fabricators, distributors, and project engineers evaluating 1/4 inch SS201 welded wire mesh. It is intended to help you compare product specifications and identify questions to resolve before placing an order. It does not replace an application-specific material review, particularly where the mesh will face moisture, chemicals, heat, or strict regulatory requirements. Share those service conditions with your supplier so the proposed material can be assessed in context.
Welded wire mesh is formed by arranging wires in perpendicular directions and joining their intersections by welding. The “1/4 inch” description refers to the nominal mesh opening, while “SS201” identifies the requested stainless steel grade. A 1/4-inch opening converts to approximately 6.35 mm, but the finished clear opening may depend on how the opening and wire diameter are specified. Always confirm the measurement convention on the quotation and product drawing.
A complete specification describes more than the opening. It should state the wire diameter, opening arrangement, sheet or roll dimensions, material grade, finish, dimensional tolerances, and any requirements for edge treatment or fabrication. If you need cut panels, framed sections, or another converted form, provide a drawing or dimensioned sketch. This makes it easier to check whether the requested configuration can be produced and packed as required.
Wire diameter directly affects the mesh’s weight, rigidity, and open area, so do not choose it by appearance alone. For instance, 0.8 mm and 1.0 mm wire diameters can be used as illustrative values when discussing a specification, but they are not a statement of standard availability or a recommendation for every application. Ask the supplier to confirm feasible wire sizes and tolerances for your opening and product format. Request a sample or drawing review when fit and handling are important.
SS201 may be considered for general-purpose mesh applications where stainless steel is specified and the operating environment is suitable for the grade. Potential uses include equipment guards, partitions, screening, racks, and fabricated components, subject to design and project requirements. These examples do not establish that SS201 is suitable for every location or load. Check the mesh’s required strength, exposure, cleaning method, and expected service conditions before selection.
Stainless steel grades do not all respond identically to corrosion conditions. Before selecting SS201, consider whether the mesh will be used indoors or outdoors, exposed to salt, cleaning chemicals, persistent moisture, or elevated temperatures. Where corrosion resistance is critical, obtain a material recommendation based on the specific environment and applicable project requirements. If the grade is mandated by a drawing or standard, verify the material documentation required for acceptance.

The 1/4-inch opening may be appropriate when the design calls for a relatively fine grid, but it does not by itself define filtration performance or prevent a particular object from passing through. Particle retention depends on the effective clear opening, wire arrangement, and the material being screened. For safety guards or load-bearing uses, evaluate the whole assembly, including supports, welds, mounting, and applied forces. Do not treat mesh opening size as a substitute for an engineering review.
Write the opening as both a nominal inch size and its metric equivalent where helpful, such as 1/4 inch (6.35 mm). State whether the dimension means clear opening or another measurement convention, and request confirmation of applicable tolerances. Specify the wire diameter separately rather than assuming it is included in the opening description. If the mesh must fit a slot or frame, provide the finished target dimensions and the required fit tolerance.
State whether you need rolls, flat sheets, cut-to-size panels, or fabricated components. As an inquiry example—not a standard product size—you might ask for panels measuring 1 m × 2 m and then have the supplier confirm feasibility. Describe the finish or surface condition required by your process, and clarify whether edges need trimming or another treatment. If the mesh will be welded into a larger assembly, share relevant drawings and joining requirements.
Ask how the supplier verifies opening size, wire diameter, panel dimensions, and weld consistency for the order. Confirm the material identification and which inspection or documentation can be provided; availability may depend on the product and purchase terms. Agree on acceptable tolerances and inspection criteria before production rather than after delivery. For critical applications, discuss sample approval and pre-shipment checks in advance.
Price depends on the specified material, wire diameter, dimensions, quantity, finishing or fabrication, packaging, and shipping terms. Minimum order quantities and lead times also depend on the production plan and requested configuration, so they should be confirmed in the quotation rather than assumed. Compare quotes using the same technical specification and delivery basis. A lower unit price may not represent a better fit if it excludes required processing, inspection, or packaging.
When you contact Shunqiang Wire Mesh, we can review your requested opening, wire diameter, grade, dimensions, and intended use to help prepare a relevant quotation. To reduce clarification time, include the quantity, product form, destination, packaging preference, and any drawing or inspection requirements in your inquiry. If a specification is incomplete, our team can identify the details that need confirmation before pricing. Final feasibility, MOQ, lead time, and documentation should be confirmed against the exact order requirements.
1/4 inch SS201 welded wire mesh may be a suitable choice when its 6.35 mm nominal opening, selected wire diameter, product dimensions, and material grade align with the application. It is not possible to determine suitability from the opening size alone, particularly where corrosion resistance, structural performance, or precise screening is important. Start by documenting the operating environment, mesh form, tolerances, and required inspection or material records. Send those details to Shunqiang Wire Mesh to request a specification review and a quotation based on your project needs.
