1/4 inch SS201 welded wire mesh is a stainless steel grid made by welding intersecting wires, with a nominal opening commonly specified as 1/4 inch, or 6.35 mm. It can suit screening, separation, guarding, and light-duty fabrication where the opening and material fit the working environment. The opening size alone does not define the product: wire diameter, mesh dimensions, finish, tolerances, and packaging also affect performance and fit. I recommend confirming those details in a written specification before requesting a quotation.
This guide is for purchasing teams, fabricators, distributors, and project engineers evaluating 1/4 inch SS201 welded wire mesh. It is intended to help you prepare a clear inquiry and compare offers on equivalent specifications. It does not assume that every supplier stocks the same wire diameter, roll width, or finish. Confirm availability and tolerances directly with the manufacturer before placing an order.
The “1/4 inch” description refers to the mesh opening, but suppliers may interpret or document opening measurements differently. A clear opening is the unobstructed gap between adjacent wires, while pitch is the distance from the center of one wire to the center of the next. Because wire diameter affects the relationship between these measurements, state which one your project requires.
For example, if a mesh has a 6.35 mm clear opening and uses 0.8 mm wire, the nominal center-to-center pitch would be 7.15 mm, assuming a regular grid and consistent wire dimensions. This is a calculation example, not a claim that a specific construction is standard or available. Ask the supplier to confirm how the opening is measured and how much dimensional variation may apply.
SS201 identifies a 201-series stainless steel material, while welded wire mesh describes the construction: longitudinal and transverse wires are joined at their intersections. The material designation should be confirmed in the supplier’s product documentation or agreed purchase specification. Do not assume that a general “stainless steel” description establishes the grade or guarantees suitability for a particular environment.
SS201 can be considered for applications where its properties and expected exposure meet the project requirements. Stainless steel grades do not perform identically in every environment, and corrosion resistance depends on conditions such as moisture, salts, chemicals, cleaning practices, and maintenance. For coastal, outdoor, food-contact, or chemically exposed service, discuss the application with your technical team and compare alternative grades if necessary.
A useful inquiry describes the finished product, not just the nominal opening and grade. The following table lists the main details to provide or request during quotation. If a value is not yet fixed, identify it as a requirement to be reviewed rather than allowing suppliers to quote different assumptions.
| Specification | What to confirm | Why it matters |
|---|---|---|
| Opening | Clear opening or center-to-center pitch; tolerance if required | Determines whether the mesh fits the screening or separation requirement |
| Wire diameter | Diameter in millimeters or inches, and permitted variation | Affects rigidity, open area, weight, and fit with adjoining parts |
| Material | SS201 grade confirmation and available material documentation | Helps verify that the quoted material matches the purchase specification |
| Product form | Sheet or roll, plus width and length | Supports cutting plans, transport planning, and yield estimates |
| Finish and edges | Surface condition, edge style, and any requested processing | Can affect handling, installation, and appearance |
| Order and packing | Quantity, bundle or roll packaging, labels, and destination | Enables a more complete quotation and shipment plan |
For screening, compare the clear opening with the size of the material you need to retain or pass through. Irregular particles, moisture, and operating movement can affect separation in ways that a nominal aperture alone cannot predict. If the process is sensitive, request a sample or evaluate a trial piece using the actual material and operating conditions.
For guards or fabricated panels, consider the required panel dimensions, support spacing, fixing method, and edge condition alongside the mesh opening. A heavier wire may offer more stiffness, but it can also change open area and add weight. Ask your fabricator or supplier to review the complete assembly rather than selecting on opening size alone.
For indoor or sheltered uses, SS201 may be a candidate when the operating environment and maintenance requirements are compatible with the grade. For salt spray, standing water, frequent washdown, or contact with aggressive chemicals, do not rely on the word “stainless” as proof of suitability. Share the exposure details and request a grade recommendation or technical review before purchase.
State whether the mesh is for screening, separation, protection, ventilation, or fabrication. Describe what must pass through or be retained, and how the mesh will be supported.

Specify a 1/4 inch clear opening or another exact measurement method. Include tolerances if the mesh must fit a defined opening or process requirement.
Tell the supplier the desired wire diameter, sheet or roll format, and finished dimensions. If you need guidance, share the load, cutting, and installation constraints rather than requesting an unspecified “standard” option.
Provide details about humidity, chemicals, cleaning, temperature, and indoor or outdoor use. Confirm the grade and any documentation required for receiving inspection.
Review specification, quantity, packaging, delivery terms, production lead time, and any inspection arrangements together. A lower quoted price is not directly comparable if the opening definition, wire diameter, or material differs.
Pricing can vary with wire diameter, mesh dimensions, quantity, product form, material confirmation, finishing, and packaging. Minimum order quantity and lead time also depend on the requested construction and current production schedule. I recommend asking for a quotation based on the same written specification for every supplier, and requesting separate pricing for different quantities when your demand is not yet fixed.
When discussing delivery, confirm whether the quoted timeline covers production only or also packing and dispatch. Share the destination and any labeling or packing requirements early, since these details can affect the final offer. If a project has a fixed delivery window, ask the supplier to confirm the schedule in writing before ordering.
Be cautious with quotations that describe only “1/4 inch stainless mesh” without defining the other key dimensions. Ask for clarification rather than assuming that two offers describe the same product. For custom or close-fit applications, align the drawing, purchase order, and supplier confirmation before production begins.
At Shunqiang Wire Mesh, we help B2B buyers clarify welded wire mesh requirements before quotation. Send us your target opening, whether it is a clear opening or pitch, wire diameter, SS201 requirement, sheet or roll dimensions, quantity, and application environment. If some details are undecided, share the intended use and constraints so we can discuss the specification and confirm what can be supplied.
1/4 inch SS201 welded wire mesh can be a practical option when its opening, wire diameter, material, and construction match the application. The essential first step is to define what “1/4 inch” measures, then specify dimensions, environmental exposure, quantity, and delivery needs. Use a complete specification to compare suppliers and reduce the risk of ordering a mesh that does not fit your process.
To request a quotation from Shunqiang Wire Mesh, prepare your mesh opening definition, wire diameter, product dimensions, quantity, and destination. We can review the requirements with you and confirm the available product details and next steps for your inquiry.
