5/8 inch SS201 welded wire mesh is a stainless steel grid with a nominal opening of 5/8 inch, or approximately 15.875 mm, made by resistance-welding SS201 wires at each intersection. I recommend it when a buyer needs a formed, uniform mesh for general separation, guarding, screening, ventilation, or light-duty fabrication and wants a more economical option than many 300-series stainless steels. The correct purchase depends on more than the opening size: wire diameter, sheet or roll format, surface condition, corrosion exposure, tolerances, quantity, and inspection requirements all affect performance. In this guide, I explain how I evaluate this mesh and how Shunqiang Wire Mesh can support project-specific sourcing.

I prepared this guide for importers, distributors, fabricators, OEM purchasing teams, contractors, and engineers comparing stainless steel welded mesh for commercial or industrial use. It is especially useful when a drawing specifies a 5/8 inch opening but does not yet define wire diameter, dimensions, finish, or packaging. It can also help buyers compare SS201 with alternative stainless grades before requesting quotations. I encourage every buyer to confirm the final specification with the supplier before production.
The term “5/8 inch” normally describes the nominal clear opening between adjacent wires, not the overall pitch from wire center to wire center. Converting the opening gives 15.875 mm, although the delivered opening may vary according to manufacturing tolerance and wire diameter. SS201 identifies the stainless steel family, while the actual chemical composition and mechanical properties should be verified against the supplier’s material documentation rather than assumed from the grade name alone.
Welded wire mesh is produced by arranging longitudinal and transverse wires in a regular grid and welding the crossings. Compared with woven mesh, welded mesh generally offers a fixed geometric pattern and welded intersections that help the panel retain its shape during handling. However, the final strength and rigidity depend on wire diameter, panel size, weld quality, edge treatment, and the way the mesh is supported in service.
| Specification | Typical buyer question | Why it matters |
|---|---|---|
| Opening size | Is the clear opening 5/8 inch or is the pitch 5/8 inch? | It affects screening, airflow, visibility, and material passage. |
| Wire diameter | What diameter is required for rigidity and load support? | It influences weight, weld strength, stiffness, and cost. |
| Material | Is SS201 acceptable for the exposure environment? | Grade selection affects corrosion resistance and purchasing cost. |
| Format | Do I need rolls, flat panels, cut pieces, or fabricated parts? | Format affects installation, freight, handling, and waste. |
| Finish | Is a standard mill finish sufficient, or is cleaning required? | Surface condition affects appearance and downstream fabrication. |
I ask buyers to specify whether 5/8 inch refers to the clear aperture or the center-to-center spacing. A 15.875 mm clear opening combined with a particular wire diameter creates a different pitch from a 5/8 inch center spacing. This distinction is important when the mesh must align with a frame, allow a defined particle size through, or meet a drawing dimension.
Wire diameter is equally important because two meshes with the same opening can have very different weights and stiffness. Buyers should provide required length, width, cutting tolerance, flatness expectations, and acceptable edge condition. If these details are unavailable, I suggest requesting a sample or a technical drawing review before placing a large order.
SS201 is commonly selected for general-purpose stainless applications where the environment is not exceptionally aggressive and cost control is important. Its corrosion performance can be less suitable than SS304 or SS316 in high-chloride, marine, acidic, or continuously wet conditions, so I do not recommend treating SS201 as a universal substitute. A supplier should confirm the offered material designation, available test documentation, and surface condition for each order.
Surface requirements may include a standard stainless finish, bright appearance, cleaned weld areas, or additional treatment after welding. Welded intersections can show localized discoloration or oxidation depending on the production process and finishing method. For visible architectural parts or demanding hygienic applications, I recommend defining the acceptable appearance and cleaning process in writing.

5/8 inch SS201 welded wire mesh may be used for machine guards, equipment covers, storage partitions, protective screens, ventilation panels, cabinet inserts, and general fabrication. Its regular openings make it practical where buyers need a predictable barrier rather than fine filtration. I would still check the required impact, load, and safety performance because mesh alone does not determine the performance of a completed guard or enclosure.
In relatively dry or moderately controlled environments, the mesh can support partitions, cages, racks, infill sections, and fabricated frames. The 15.875 mm nominal opening can provide a balance between visibility, airflow, and physical separation. For outdoor projects exposed to deicing salt, coastal spray, fertilizer, or persistent moisture, I advise comparing SS201 with SS304 or another more suitable material before final approval.
I would avoid making SS201 the default choice for direct food-contact systems, marine equipment, chemical processing, or applications where corrosion failure would create a significant safety or maintenance risk unless the responsible engineer has approved it. Galvanized steel, painted carbon steel, SS304, SS316, or a polymer-coated mesh may be better depending on the environment and budget. The right alternative should be selected from exposure conditions, required service life, fabrication method, and applicable project standards.
Pricing usually changes with stainless material cost, wire diameter, mesh dimensions, order quantity, welding settings, cutting, finishing, packaging, and freight. I do not advise comparing quotations on price per square meter alone because a lower unit price may exclude cutting, edge processing, special packing, or inspection. Ask each supplier to quote the same opening definition, wire diameter, dimensions, quantity, Incoterm, and documentation.
Minimum order quantity and lead time depend on production scheduling, raw material availability, tooling, customization, and destination. A buyer should request a written production estimate instead of assuming that a standard size is immediately available. For planning purposes, I recommend separating sample approval, production time, inspection, and shipping time into four distinct schedule stages.
As Shunqiang Wire Mesh, I focus on translating a buyer’s drawing or application requirement into a clear welded mesh specification. I can discuss opening, wire diameter, panel or roll format, SS201 material needs, cutting requirements, packaging, and export coordination before quotation. Where the application appears too corrosive or mechanically demanding for SS201, I prefer to raise that limitation and compare alternatives rather than provide an unsupported guarantee.
5/8 inch SS201 welded wire mesh is a practical candidate for general separation, guarding, screening, ventilation, and fabrication when the environment is not highly corrosive and the design does not require a higher stainless grade. I would approve it only after confirming the clear opening, wire diameter, dimensions, weld quality, surface expectations, and exposure conditions. The most important next step is to prepare a complete inquiry rather than request “5/8 inch mesh” alone.
Send Shunqiang Wire Mesh your required opening definition, wire diameter, width, length, quantity, application, finish, and destination. I can then help you review the specification, identify potential material limitations, and prepare a quotation suited to your purchasing and fabrication needs. This process gives you a clearer basis for comparing SS201 welded wire mesh suppliers and selecting a dependable supply solution.
