A 1.5 inch stainless welded mesh panel is a rigid wire mesh sheet made by welding stainless steel wires at regular intersections, with a nominal opening of 1.5 inches, or 38.1 mm. It is commonly selected when a project needs defined openings, good airflow or visibility, and better resistance to moisture and corrosion than ordinary carbon steel mesh. The final performance depends on the stainless steel grade, wire diameter, panel dimensions, welding quality, surface condition, and installation environment.
At Shunqiang Wire Mesh, I help B2B buyers evaluate these variables before quotation. A practical purchasing specification should identify the opening size, wire diameter, steel grade, panel size, edge treatment, quantity, and required finish. Because “1.5 inch” describes the opening rather than the complete product, it is not enough information for accurate sourcing by itself.
This product consists of longitudinal and transverse stainless steel wires joined at each crossing point by resistance welding or a comparable welding process. The welded construction creates a fixed grid, which is different from woven mesh where wires pass over and under one another. The 1.5 inch specification normally refers to the nominal clear opening between wires, although suppliers may describe mesh size by center-to-center spacing in some quotations.
The panel format makes the mesh easier to cut, frame, bolt, or install as a rigid component. Unlike flexible rolls, panels are generally preferred when the project requires a stable shape and repeatable dimensions. However, the appropriate panel thickness and support structure still depend on span, load, vibration, and the intended safety function.
| Specification | What It Controls | Buyer Question |
|---|---|---|
| Opening size | Airflow, visibility, passage, and screening behavior | Is 1.5 inch a clear opening or center-to-center spacing? |
| Wire diameter | Rigidity, weight, open area, and cost | What wire diameter is required for the application? |
| Stainless grade | Corrosion resistance, material cost, and service suitability | Is 304 or 316 more appropriate for the environment? |
| Panel dimensions | Installation efficiency, framing, and shipping | What length, width, and dimensional tolerance are needed? |
| Edge treatment | Handling safety and connection method | Should edges be cut, deburred, folded, or framed? |
304 stainless steel is often considered for general industrial, architectural, food-processing support, and indoor or moderately exposed environments. It provides a balance between corrosion resistance, availability, and cost. It should not be treated as universally suitable, because chemicals, salt exposure, cleaning agents, temperature, and moisture can change the material requirement.
316 stainless steel contains molybdenum and is commonly evaluated for environments with greater chloride exposure, including coastal locations or selected chemical-processing conditions. The correct grade must be chosen from the actual operating environment rather than from price alone. If the application involves strong chemicals, high temperatures, or sanitary regulations, I recommend that the buyer provide the relevant operating information for technical review.
Stainless welded mesh panels may be supplied with a mill finish, cleaned surface, polished appearance, or other treatment depending on the production route and customer requirements. Welding can create localized discoloration or heat-affected areas, so surface cleaning and passivation requirements should be stated clearly when appearance or corrosion performance is important. I do not recommend assuming that every stainless panel has the same surface condition.
The open 1.5 inch grid can be used where full closure is not required. Typical applications include machine guards, equipment partitions, storage cages, protective barriers, ventilation screens, agricultural structures, warehouse dividers, and fabricated frames. The panel can also be used as an infill component when it is properly supported by a steel, stainless steel, or aluminum frame.
For industrial guarding, the mesh should be assessed together with the surrounding frame, access doors, fasteners, and the hazard being controlled. A large opening may not be appropriate where small objects, fingers, tools, or animals must be prevented from passing through. For architectural or decorative use, buyers should also consider the visual direction of the grid and the consistency of panel dimensions.
First, I ask whether the mesh is intended for separation, protection, screening, support, airflow, or appearance. The function determines whether the main priority is opening size, stiffness, corrosion resistance, cleanability, or visual quality. A panel selected only by its nominal opening may fail to meet the actual project requirement.
Next, specify wire diameter, panel length and width, grid orientation, edge condition, and connection method. If the panel is used horizontally or across a long span, provide the expected support spacing and load information so the construction can be reviewed. For a safety barrier, state whether the mesh is intended as a guard, a partition, or a non-structural infill.

Compare the exposure conditions with the available stainless grades. 304 may be suitable for many general environments, while 316 may be considered when chloride or marine exposure is a significant concern. Specify whether the project needs deburring, cleaning, passivation, polishing, or protective packaging, because these requirements can influence both price and production planning.
A useful quotation should show the mesh opening, wire diameter, material grade, panel size, quantity, edge treatment, packaging, and inspection basis. I also recommend asking whether the stated opening is clear opening or pitch, and whether dimensions are nominal or subject to an agreed tolerance. For repeat orders, an approved drawing or sample can help reduce interpretation differences.
The price of a 1.5 inch stainless welded mesh panel is influenced by stainless grade, wire diameter, panel size, order quantity, welding setup, edge processing, surface treatment, packaging, and shipping terms. Larger wire and heavier panels generally require more material, while special finishes and custom dimensions can add processing steps. A low unit price may not represent the lowest total cost if panels require extensive cutting, rework, or unsuitable packaging.
Minimum order quantity and production lead time vary according to whether the product is a standard configuration or a custom fabrication. Stock availability, raw material scheduling, tooling, panel size, and inspection requirements should be confirmed for each purchase. I provide more useful feedback when buyers send a target quantity, destination, dimensions, grade, and application instead of requesting a price for “1.5 inch stainless mesh” alone.
One frequent mistake is confusing a 1.5 inch clear opening with a 1.5 inch pitch. Another is selecting 304 or 316 without considering the actual chemical and atmospheric exposure. Buyers may also overlook panel flatness, sharp cut edges, weld consistency, protective film, and the compatibility of stainless mesh with dissimilar metal frames.
It is also important not to treat the mesh as a structural product without reviewing the complete assembly. Panel performance depends on wire diameter, unsupported span, frame design, fasteners, impact, and installation quality. If the mesh is intended to protect people or equipment, the buyer should complete an application-specific safety review rather than relying on the opening size alone.
At Shunqiang Wire Mesh, I approach this product as a specification and supply project rather than a simple catalog item. We can review the required opening, wire diameter, stainless grade, panel dimensions, edge treatment, and intended use before confirming a production solution. This process helps buyers compare quotations on equivalent specifications.
Our support can include configuration review, custom panel sizing, production coordination, packaging discussion, and export-oriented order communication. Availability depends on the requested material, dimensions, quantity, and processing requirements, so I confirm these details before making a delivery commitment. Buyers can improve quotation accuracy by sending a drawing, reference photo, or complete technical schedule.
A 1.5 inch stainless welded mesh panel is a suitable starting point when a project needs a rigid, open grid with stainless steel corrosion resistance, but the opening size alone does not define the correct product. The final selection should combine 38.1 mm opening terminology, wire diameter, stainless grade, panel dimensions, finish, edge treatment, and installation conditions. This is the most reliable way to balance performance, cost, and sourcing risk.
To begin an inquiry with Shunqiang Wire Mesh, provide the required quantity, panel dimensions, preferred grade, wire diameter, application environment, and destination. If some specifications are not yet decided, send the project goal and available drawing instead. I can then help establish a clear specification, identify suitable options, and prepare a quotation for your 1.5 inch stainless welded mesh panel requirement.
