1/4 inch SS201 welded wire mesh is a stainless steel grid made by welding intersecting wires, with a nominal square opening of 1/4 inch (6.35 mm). It can suit applications that need a relatively small, regular opening and a stainless steel construction, such as selected screening, guards, partitions, and general fabrication. The opening size alone does not define the product: wire diameter, sheet or roll dimensions, finish, and the environment all affect suitability. We recommend confirming those details with your supplier before ordering, especially if corrosion exposure or dimensional tolerances are important.

This guide is for procurement teams, fabricators, distributors, and project engineers comparing 1/4 inch SS201 welded wire mesh for a specific application. It is intended to help you prepare a clear request for quotation and assess whether this material and opening size fit your operating conditions. It does not replace a project-specific engineering review or a supplier’s material documentation. Where a product must meet a code, regulated use, or defined corrosion requirement, confirm compliance directly with the responsible technical team and supplier.
The “1/4 inch” description normally refers to the nominal spacing of the mesh openings, but buyers should confirm the supplier’s measurement convention. A quarter inch equals 0.25 in, or 6.35 mm. Clear opening, center-to-center spacing, and manufacturing tolerance are not interchangeable, so a drawing or written specification can prevent misunderstandings.
In welded wire mesh, wires cross at regular intervals and are joined at their intersections. This creates a grid that can be supplied in sheets or rolls, depending on the product configuration and manufacturing capability. The finished mesh’s rigidity and handling characteristics depend in part on wire diameter, opening geometry, and panel or roll dimensions.
SS201 identifies a stainless steel grade, but the label by itself does not establish that a mesh is suitable for every outdoor, wet, or chemical environment. Corrosion performance depends on the exact material specification, exposure conditions, fabrication, cleaning, and maintenance. Buyers should describe the intended environment rather than relying on the grade name alone.
When documentation matters, ask which material standard or specification applies and what paperwork can accompany the order. Do not assume that a grade designation guarantees a particular certificate or test result. We advise buyers to align the quotation, product marking, and material documents with the requirements of their own project.
A complete product specification helps both buyer and supplier quote the same item. In addition to the opening, identify wire diameter and whether the requested dimension is nominal or subject to a specified tolerance. For an initial comparison, buyers might ask about illustrative wire diameters such as 0.8 mm, 1.0 mm, and 1.2 mm; these are inquiry examples, not a statement that every size is available from stock.
| Specification | What to clarify | Why it matters |
|---|---|---|
| Opening | Nominal 1/4 inch (6.35 mm); confirm clear or center-to-center measurement | Determines the grid spacing and how the mesh fits the application |
| Wire diameter | State the required diameter in millimeters and any tolerance | Affects mesh weight, rigidity, and fit with supporting components |
| Format and dimensions | Sheet or roll; specify width, length, and edge requirements | Helps assess handling, cutting, installation, and material yield |
| Material and finish | Confirm SS201 specification, surface condition, and available documentation | Supports review of material identity and application suitability |
| Order requirements | Quantity, packaging, delivery destination, and inspection needs | Allows a supplier to provide a realistic commercial quotation |
The 6.35 mm nominal opening may be considered for screening, protective covers, equipment guards, partitions, and fabricated components where a regular welded grid is required. Whether it works depends on what must pass through the opening, the loads the mesh will encounter, and how it will be supported. These examples are potential use cases, not a guarantee of performance in a particular installation.

For indoor or relatively mild service conditions, SS201 may be considered when the project specification permits it and the exposure is compatible with the material. For sustained moisture, coastal air, cleaning chemicals, or other aggressive conditions, ask a qualified technical reviewer to evaluate the grade and compare suitable alternatives. If corrosion resistance is a critical requirement, base the decision on the actual environment and applicable material documentation rather than price or grade label alone.
Mesh is often installed as part of a larger assembly, so consider the frame, fasteners, welds, cut edges, and cleaning process as well as the mesh itself. Dissimilar materials or retained contaminants can affect the service condition of a finished assembly. Share installation drawings and exposure details with the supplier when they may influence product selection or fabrication.
Pricing can vary with wire diameter, panel or roll dimensions, order quantity, finish, packaging, and requested documentation. Minimum order quantity and production lead time also depend on the exact configuration and the supplier’s current schedule. We do not recommend relying on a generic price or lead-time estimate without a written quotation for your specification.
To obtain a comparable quote, send the same technical and commercial details to each supplier. Ask them to identify any deviations from your requested opening, wire diameter, dimensions, or material documentation. Confirm whether the quoted lead time begins after order confirmation, drawing approval, or another agreed milestone.
A capable supplier should be able to discuss the product specification clearly and identify which details require confirmation. Ask whether the quoted mesh is SS201, how the opening and wire diameter are measured, and what tolerances or documentation apply. If your product will be fabricated or installed into a defined assembly, request a drawing review or sample assessment where practical.
Also check that the quotation states format, dimensions, quantity, packaging, destination, and delivery terms. Ask how the supplier handles specification changes and how nonconforming material concerns are communicated. As Shunqiang Wire Mesh, we encourage buyers to share drawings, target quantities, and operating conditions so we can review the request and confirm the available configuration before order placement.
1/4 inch SS201 welded wire mesh has a nominal opening of 6.35 mm and may suit selected screening, guarding, partition, and fabrication needs when its material and construction match the application. The opening size is only a starting point; wire diameter, dimensions, finish, exposure conditions, and documentation determine whether a particular product is appropriate. Before purchasing, prepare a written specification and ask suppliers to confirm each critical detail.
For a quotation from Shunqiang Wire Mesh, provide your required opening, wire diameter, sheet or roll dimensions, order quantity, destination, and intended service environment. If you have a drawing, sample requirement, or material-documentation request, include it with your inquiry. We can then review the configuration and clarify the supply details before you proceed.
