1.18 Inch SS304 Welded Wire Mesh Panel: Specifications and Buying Guide

A 1.18 inch SS304 welded wire mesh panel is a stainless steel grid made by resistance-welding intersecting wires, with “1.18 inch” identifying the stated mesh opening. That dimension converts to approximately 29.97 mm, but buyers should confirm whether it describes the clear opening between wires or the center-to-center spacing. The opening alone does not define the panel: wire diameter, panel dimensions, edge finish, tolerances, and service conditions also affect whether it suits your project. Use this guide to prepare a complete specification and compare supplier quotations on a consistent basis.

Key Takeaways

• Confirm whether 1.18 inches means clear opening or wire-center spacing before approving a drawing or quotation.
• Specify SS304, wire diameter, panel length and width, dimensional tolerances, edge condition, and quantity.
• Match the grade and panel construction to the operating environment; stainless steel does not eliminate every corrosion risk.
• Ask suppliers to identify what is included in the price, such as packaging, inspection documents, and delivery terms.

Who This Guide Is For

This guide is for procurement teams, fabricators, engineers, and distributors sourcing welded wire mesh panels for industrial or commercial use. It is particularly useful when a project drawing specifies a 1.18 inch opening but leaves other product details open. The information can help you build a clear RFQ, review supplier responses, and identify questions that should be resolved before production.

Understanding the Product and Its Specifications

What “1.18 Inch SS304 Welded Wire Mesh Panel” Means

“SS304” generally refers to Type 304 stainless steel, while “welded wire mesh panel” describes wires joined at their intersections and supplied as a flat or formed panel. The 1.18 inch figure refers to the stated mesh opening, but industry documents may use different conventions for measuring that opening. A drawing or purchase order should therefore define the measurement method rather than relying on the product name alone.

If 1.18 inches is the clear opening, the distance from one wire surface to the next is approximately 29.97 mm. If it is a center-to-center spacing, the clear opening will be smaller by approximately one wire diameter. For example, with a 3 mm wire, a 29.97 mm center spacing would correspond to an approximately 26.97 mm clear opening, assuming the spacing is measured in the same direction.

Specifications to Include in Your RFQ

A useful RFQ states the measurable product requirements and distinguishes them from preferences. Include a drawing where possible, especially if the panel has cut-outs, special edges, or a nonstandard layout. If an item is not fixed, mark it as a requested quotation option rather than leaving the supplier to make an assumption.

Material, Wire, and Fabrication Choices

SS304 is commonly selected where a stainless material is wanted for general corrosion resistance and cleanability. Its suitability depends on the actual exposure, including chemicals, moisture, temperature, cleaning methods, and contact with other materials. Do not treat the grade name as a guarantee of performance in every environment; request engineering review or consider an alternative grade if the service conditions are aggressive or uncertain.

Wire diameter affects the panel’s weight, open area, stiffness, and handling characteristics. A larger wire can reduce the open area when the opening is held constant, so buyers should evaluate the balance between passage requirements and mechanical demands. Weld quality, flatness, edge finishing, and cut accuracy should also be defined according to how the panel will be installed and used.

Matching the Panel to an Application

Welded mesh panels may be used in equipment guarding, partitions, storage structures, screening, and fabrication assemblies, depending on the wire size and design. The 1.18 inch opening may be appropriate where a relatively open grid is acceptable, but it is not automatically suitable for fine screening, small-particle retention, or applications requiring a close barrier. Confirm the required opening against the smallest material, object, or access restriction relevant to the application.

For guards or partitions, check whether the panel opening and wire arrangement meet the project’s safety and access requirements. For screening or separation, consider the relationship between clear opening, wire diameter, and the behavior of the material being handled. For fabricated assemblies, account for attachment points, cut edges, panel orientation, and whether the mesh will be supported along its full perimeter or only at selected locations.

A Practical Selection Framework

Step 1: Define the Opening Measurement

Write “clear opening” or “center-to-center spacing” directly into the specification, and identify the measurement direction if the design uses different horizontal and vertical spacing. If the stated 1.18 inches comes from an existing component or drawing, provide that reference to the supplier. This prevents a nominally matching panel from arriving with an opening that differs from the project’s intended usable space.

With competitive price and timely delivery, Shunqiang Wire Mesh sincerely hope to be your supplier and partner.

Step 2: Set Mechanical and Dimensional Requirements

State the wire diameter and finished panel dimensions, then define allowable tolerances where they matter for assembly. Indicate whether the panel must remain flat, fit a frame, or be cut to shape. If load, impact, or safety performance is important, provide the design conditions and have a qualified engineer confirm the required construction rather than selecting by appearance alone.

Step 3: Review Environment and Finish

Describe exposure to water, cleaning agents, chemicals, outdoor conditions, or heat. Ask the supplier to confirm the offered material and finish against those conditions, while treating the final material choice as a project-specific decision. Also clarify whether the panel will be supplied as welded, cut, deburred, or otherwise processed.

Step 4: Compare Quotations on the Same Basis

Compare suppliers only after aligning the opening definition, wire diameter, material, panel size, quantity, and finish. Check whether the quotation includes packaging, inspection requirements, documentation, and delivery to the stated destination. A lower unit price may not represent a lower total cost if the product differs from the drawing or requires extra processing after delivery.

Pricing, MOQ, and Lead Time

Pricing for a welded mesh panel depends on the confirmed material, wire diameter, opening, dimensions, order quantity, fabrication requirements, packaging, and delivery terms. Minimum order quantity and production lead time can vary by specification and supplier, so they should be confirmed in the quotation rather than assumed from a general product description. For an accurate offer, submit the drawing or dimensions, required quantity, destination, and target schedule together.

When requesting a quotation, ask the supplier to state whether the price is based on standard or custom dimensions and whether any tooling, cutting, or packing costs apply. If your project can accept alternatives, request separate options—for example, different panel sizes or finishes—so the trade-offs are visible. Confirm the quote’s validity period and how schedule changes will be handled before placing an order.

Supplier Evaluation Checklist

• Does the supplier confirm the opening as clear or center-to-center?
• Are SS304, wire diameter, panel size, tolerances, and edge requirements clearly stated?
• Can the supplier review a drawing and identify any unresolved specification points?
• Are inspection, material documentation, packaging, MOQ, and lead time described in writing?
• Does the quotation match the required delivery terms and destination?

Ask for clarification when a quotation uses broad descriptions such as “standard mesh” without listing measurable dimensions. Where documentation or inspection is required, define it before production and confirm what the supplier can provide. A written, agreed specification is more useful for avoiding misunderstandings than relying on a product name alone.

How Shunqiang Wire Mesh Can Support Your Sourcing

Shunqiang Wire Mesh can review your requested 1.18 inch SS304 welded wire mesh panel specification and help identify details needed for a clear quotation. Share the opening measurement method, wire diameter, panel dimensions, quantity, application environment, and any drawing or inspection requirements. If some details are not yet fixed, state your priorities so available options can be discussed against the project needs.

Conclusion

A 1.18 inch SS304 welded wire mesh panel can be assessed effectively when the opening definition is clear and the rest of the construction is specified. Confirm whether 1.18 inches refers to the clear opening or center spacing, then define wire diameter, panel dimensions, tolerances, edge finish, and service conditions. These details enable a more meaningful comparison of price, MOQ, and lead time.

Your next step is to prepare a drawing or RFQ containing those requirements and ask suppliers to confirm each item in writing. Send the specification and target quantity to Shunqiang Wire Mesh for a project-based quotation and clarification of any open points.
