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 with nominal openings of 1.18 inches, made by resistance-welding intersecting wires. The opening converts to approximately 29.97 mm, or about 30 mm, measured from wire center to wire center when specified as a center-to-center mesh pitch; buyers should confirm the measurement convention before ordering. The opening size alone does not define the panel: wire diameter, panel dimensions, edge finish, tolerances, and grade documentation also affect suitability and price. This guide explains what to confirm so you can compare offers and request a panel matched to your project.

Key Takeaways

• Confirm whether 1.18 inches refers to the clear opening or the wire center-to-center spacing.
• Specify SS304, wire diameter, panel size, tolerances, and edge treatment separately; do not assume they are standard.
• Match the mesh opening and wire diameter to the required containment, screening, airflow, and mechanical performance.
• Provide a complete written specification when requesting pricing, samples, or production lead time.

Who This Guide Is For

This guide is for importers, fabricators, distributors, and project buyers sourcing stainless steel welded mesh panels for industrial or commercial use. It is also useful for engineers who need to turn a general requirement such as “1.18 inch SS304 mesh” into a purchasable specification. The information supports supplier discussions but does not replace design review where loads, safety, or regulated applications are involved. Confirm project requirements with the responsible technical team before finalizing an order.

Understanding the Specification

What “1.18 Inch SS304 Welded Mesh” Means

“1.18 inch” describes the nominal spacing of the mesh, while “SS304” identifies the requested stainless steel grade. In welded mesh, longitudinal and cross wires meet at regular intervals and are joined at their intersections. The resulting grid can be supplied as panels, with panel width, length, and finish determined by the order specification. The term by itself does not state wire thickness, panel size, surface condition, or allowable dimensional variation.

There are two commonly confused ways to describe mesh spacing: clear opening and pitch. Clear opening is the unobstructed distance between the inside edges of adjacent wires; pitch is measured from the center of one wire to the center of the next. If 1.18 inches is the pitch, the clear opening will be smaller by approximately one wire diameter, subject to the actual wire dimensions. State the measurement method on your drawing or purchase specification to reduce interpretation differences.

Material and Construction Options

SS304 is a widely specified austenitic stainless steel grade for general corrosion-resistance needs. Its suitability depends on the operating environment, including exposure to chemicals, salts, moisture, temperature, and cleaning agents. It should not be treated as universally corrosion-proof; for chloride-rich or otherwise aggressive conditions, ask a qualified engineer whether another alloy is more appropriate. When material verification matters, request the available grade documentation and clarify what documents can be supplied with the order.

Welded wire panels may differ in wire diameter, grid alignment, weld appearance, edge condition, and surface finish. A buyer may request a cut edge, framed edge, or another fabrication detail, depending on installation and handling needs. These options can affect production steps, packaging, and cost, so include them in the initial inquiry rather than assuming they are included. Final availability depends on the supplier’s production capability and the approved drawing.

Core Specifications to Confirm

Use a written specification to make supplier quotations comparable. The table below separates the nominal mesh description from the details that still need confirmation. The metric conversion is arithmetic: 1 inch equals 25.4 mm, so 1.18 inches equals 29.972 mm, commonly rounded to 29.97 mm. This conversion does not establish a manufacturing tolerance.

Matching the Panel to Its Application

A nominal 30 mm spacing may suit projects that need an open grid, but it will not retain particles smaller than the effective opening. For screening, compare the required separation size with the actual clear opening rather than relying only on the nominal 1.18 inch label. For guards, partitions, or equipment enclosures, consider access, visibility, airflow, edge safety, and the support structure. The mesh panel is only one part of the installation, so evaluate how it will be fixed and supported.

Wire diameter should be selected alongside the opening size. A thicker wire generally occupies more of the grid and can increase rigidity, but it also changes weight and available open area. As examples for quotation comparison—not as guaranteed standard offerings—a buyer could ask a supplier to quote 2 mm, 3 mm, and 4 mm wire options, provided those sizes are feasible for the requested mesh and panel dimensions. Ask for the actual drawing or sample when precise fit and appearance are important.

A Practical Selection Framework

Step 1: Define the Operating Conditions

Record what the panel must do, what it will contact, and where it will be installed. Note moisture, cleaning chemicals, outdoor exposure, temperature, and any risk of impact or vibration. These details help determine whether SS304 is a reasonable starting grade and whether the panel needs added framing or a particular finish. If the environment is uncertain or aggressive, seek materials advice before placing an order.

Step 2: Specify Geometry and Tolerances

Provide a dimensioned drawing or a clear schedule stating the spacing convention, wire diameter, panel width, panel length, and quantity. Identify whether spacing applies in both directions and whether the grid must align symmetrically at the edges. State acceptable dimensional variation if the panel must fit a frame or machine opening. If you do not have a drawing, ask the supplier to prepare one for written approval before production.

Step 3: Review Fabrication and Inspection Needs

Clarify edge treatment, welding appearance, flatness expectations, surface condition, and packaging requirements. Ask how the supplier will check the dimensions that matter to your installation, and agree on the inspection basis before production. Where material traceability or documents are required, list the exact document type in the purchase inquiry. Do not assume a certificate, test report, or inspection record is included unless the supplier confirms it.

Step 4: Compare Quotations on Equal Terms

Compare offers only after confirming that they use the same mesh measurement, material, wire diameter, panel size, finish, and quantity. A lower price may reflect a different specification, packaging arrangement, or scope of documentation. Request a breakdown of production price, packaging, shipping terms, and any tooling or customization charges that apply. Confirm the proposed production lead time and how it is calculated, since material availability and order details may affect the schedule.

Pricing, MOQ, and Lead Time

Pricing for welded mesh panels depends on material, wire diameter, panel dimensions, order quantity, fabrication, finishing, packaging, and delivery requirements. A customized panel may require additional setup or drawing confirmation, while a repeat order with an approved specification can be easier to quote consistently. Minimum order quantity and lead time vary by supplier, product configuration, and production schedule. We recommend requesting these details directly rather than relying on a generic estimate.

For a useful quotation, submit the requested quantity and destination along with a complete technical specification. Ask the supplier to identify any deviations or assumptions in the offer, especially around opening measurement and tolerances. If you need a sample, confirm its dimensions, material identification, shipping cost, and whether sample approval will be used as the production reference. This process helps prevent avoidable differences between the approved sample and bulk order.

Supplier Evaluation Checklist

• Can the supplier confirm the opening measurement convention and provide a dimensioned drawing?
• Can they quote the requested SS304 grade, wire diameter, panel size, and edge finish?
• Will the quotation state tolerances, quantity, packaging, shipping terms, and lead time?
• Can they explain what inspection or material documents are available for the order?
• Will they record approved specifications so repeat orders can be compared consistently?

Ask for clear written answers rather than relying on broad claims about quality or capability. If your use involves structural loading, personnel protection, or a regulated process, request technical review against the applicable project requirements. A supplier can manufacture to an agreed specification, but the buyer or project engineer must establish that the specification is suitable for the intended duty. Keep the approved drawing and order confirmation with your purchasing records.

Common Buying Mistakes

One frequent mistake is ordering by opening size alone and leaving wire diameter undefined. Another is treating a pitch measurement as a clear opening, which can produce a panel that does not screen or fit as expected. Buyers may also overlook edge treatment, dimensional tolerance, or whether the panel must be flat enough for a particular frame. A complete inquiry should resolve these details before commercial terms are finalized.

It is also risky to assume SS304 will suit every exposure or that a supplier’s standard panel matches a project drawing. Confirm grade, finish, and environmental suitability rather than inferring them from a product name. For custom orders, make approval of the drawing and specification a defined step before production. That written record is a practical safeguard for both buyer and supplier.
