1/4 inch SS201 welded wire mesh is a stainless steel grid made by welding wires at their intersections, with a nominal opening of 1/4 inch (6.35 mm). The opening size alone is not a complete specification: wire diameter, opening measurement method, sheet or roll dimensions, finish, and tolerances also affect suitability and price. SS201 can be a practical choice for applications where a stainless steel mesh is needed in a relatively mild environment, but it should not be treated as interchangeable with more corrosion-resistant grades in every setting. In this guide, I explain what to confirm before requesting a quotation from Shunqiang Wire Mesh.
This guide is for importers, fabricators, distributors, and project buyers comparing 1/4 inch SS201 welded wire mesh. It is useful if you need to prepare a purchase specification, evaluate supplier quotations, or check whether SS201 fits your operating environment. If your project involves salt spray, frequent chemical exposure, or strict food-contact requirements, use the selection steps below to identify what additional material or compliance review may be needed.
The phrase “1/4 inch” normally refers to the nominal spacing of the mesh openings, but a buyer should confirm whether the quoted dimension is measured clear between wires or center-to-center. These methods produce different usable openings, particularly when wire diameter changes. Welded mesh holds wires together at their crossing points, creating a regular grid; the finished product’s consistency depends on the specified dimensions and manufacturing controls.
One-quarter inch converts to 6.35 mm. This conversion is a useful reference when suppliers quote in metric units, but buyers should state the preferred unit and clarify allowable tolerances rather than assume that every product described as 1/4 inch will have identical finished openings. A written drawing or specification can prevent confusion between nominal and measured dimensions.
SS201 identifies a 201-series austenitic stainless steel grade. Its composition and mechanical properties are governed by the applicable material standard and product form, so a grade name by itself does not confirm a particular chemical analysis, finish, or corrosion performance. Ask the supplier what material documentation is available for the offered batch and verify that it matches the standard and requirements in your purchase order.
In general, SS201 is considered for applications where cost and general stainless-steel utility matter, while its corrosion resistance is typically less suitable than SS304 in more aggressive environments. Actual performance depends on conditions such as moisture, chlorides, chemicals, cleaning methods, and surface condition. For coastal, outdoor, or chemical-service use, describe the exposure to your supplier and technical team before choosing the grade.
| Specification | What to state or confirm | Why it matters |
|---|---|---|
| Mesh opening | 1/4 inch (6.35 mm); clear opening or center-to-center | Defines the grid and prevents measurement misunderstandings. |
| Wire diameter | Required diameter in mm or gauge, plus tolerance | Affects mesh weight, rigidity, open area, and fabrication fit. |
| Product form | Sheet or roll; finished length, width, and quantity | Determines handling, cutting, packing, and freight planning. |
| Material and finish | SS201 grade requirement, surface condition, and documentation needs | Helps verify suitability and align the delivered product with the order. |
| Tolerances and welding | Dimensional tolerances and acceptable weld appearance or defects | Reduces disputes during inspection and downstream assembly. |
Wire diameter must be specified separately; it is not implied by a 1/4 inch opening. For example, a drawing might call for a 1.0 mm wire, but that is only an illustrative specification, not a standard or guaranteed option. The buyer and supplier should confirm manufacturability, final opening, tolerances, and intended load or handling conditions together.
A 1/4 inch opening can be considered for general screening, partitions, protective covers, fabrication components, and other uses where the opening size and welded construction meet the design need. Whether it performs adequately depends on factors such as wire diameter, panel dimensions, support spacing, applied loads, and exposure conditions. Do not select a mesh based on opening size alone when it must carry a load or provide a defined level of protection.
For an indoor divider or a non-critical guard in a relatively dry setting, SS201 may be worth evaluating as a cost-conscious stainless option. For persistent dampness, salt exposure, frequent washdown, or contact with corrosive substances, request a material review and consider whether another grade is more appropriate. Where the mesh is used in a regulated or hygiene-sensitive application, confirm applicable requirements independently rather than assuming the grade name is sufficient.

Start with the mesh’s function: screening, separation, guarding, or fabrication. Record whether it will be installed indoors or outdoors and note exposure to water, salt, cleaners, or chemicals. This information helps a supplier assess whether SS201 is a reasonable candidate or whether the material selection needs further review.
State the opening, measurement method, wire diameter, product form, and finished dimensions. If the order is for a panel, give its required width and length; if it is for a roll, specify the required roll width and length. As an example of how to describe a trial request, a buyer might ask for a 1 m by 2 m sample panel, but this is an example only and should not be taken as a standard stock size.
Agree how opening size, wire diameter, overall dimensions, and weld condition will be checked. Identify whether you need a material certificate, inspection report, or other documents, and confirm availability before placing the order. If tolerances are important to assembly, include them in the drawing or purchase specification rather than relying on a verbal description.
Compare quotations using the same material grade, dimensions, tolerance requirements, surface condition, quantity, packaging, and delivery terms. Ask whether the quoted price includes any cutting, packing, inspection, or export preparation that your order requires. Minimum order quantity and lead time can vary with product dimensions, order volume, production scheduling, and destination, so request written confirmation for your specific inquiry.
There is no reliable universal price for 1/4 inch SS201 welded wire mesh without a complete specification. Wire diameter, sheet or roll size, quantity, finishing requirements, packaging, and shipping destination can all affect the quotation. A larger wire diameter may change material consumption and handling requirements, while custom dimensions may affect production planning.
MOQ and lead time should also be confirmed for the exact order rather than inferred from a general product description. For planning, share your target quantity, delivery location, required arrival date, and whether you can accept standard dimensions. If you are testing fit or quality, ask whether a sample or small trial order is possible and clarify its cost and schedule.
At Shunqiang Wire Mesh, I recommend sending a drawing or a complete dimensional schedule along with your application details. This gives us a clearer basis to review the requested mesh, confirm the information needed for a quotation, and discuss any specification points that require clarification. Availability, customization, documents, MOQ, and delivery timing should be confirmed against each order.
1/4 inch SS201 welded wire mesh is a defined starting point, not a complete purchasing specification. To choose the right product, confirm the 6.35 mm nominal opening and its measurement method, specify wire diameter and finished dimensions, and check that SS201 suits the actual environment. These steps help reduce specification gaps and make supplier quotations easier to compare.
For a quotation from Shunqiang Wire Mesh, prepare your required quantity, mesh dimensions, wire diameter, product form, tolerance expectations, destination, and application conditions. Send those details for review, and ask us to confirm the material, production options, lead time, and documentation available for your order.
