An electro galvanized welded mesh roll carries a thin, even electrolytic zinc layer with a smooth, bright surface for visible indoor installations and dry-service enclosures. Match the coating route to the real exposure, define the opening and wire basis, then send your selected SKUs and cutting layout for a quotation.
FOB reference price from $2.60 / m². Varies by spec and quantity; final quote on inquiry.

Use the bright finish where the grid stays visible and the exposure stays dry or sheltered. Confirm the opening, supports and maintenance plan before treating any route as interchangeable.
Electrolytic zinc behaves differently from hot-dip and polymer finishes. Use its characteristics deliberately instead of treating every galvanized mesh as interchangeable.
Note whether the listed wire diameter is the base wire or the finished coated size, and whether opening means clear gap or centre-to-centre pitch. Keep the coating route beside each selected SKU. Worked figures are assumed teaching values; they do not add specifications to this catalog.

These electro galvanized welded mesh roll examples compute the nominal square opening from each listed SKU's mesh count and wire diameter. Mesh count is wires per linear inch, not a direct reading of the gap; the calculation shows how a heavier wire at the same count narrows the opening.
| Mesh per inch | Wire diameter (mm) | Calculated opening (mm) | Calculated opening (μm) |
|---|---|---|---|
| 2 | 1.6 | 25.4 ÷ 2 − 1.6 ≈ 11.1000 mm | 11100.0 |
| 4 | 0.8 | 25.4 ÷ 4 − 0.8 ≈ 5.5500 mm | 5550.0 |
| 8 | 0.5 | 25.4 ÷ 8 − 0.5 ≈ 2.6750 mm | 2675.0 |
Calculated openings use four decimal places in millimetres and one in micrometres; catalog apertures are rounded separately. On this thin-coating route the finished wire stays close to the listed size, but confirm the measurement basis before checking the opening against your requirement.

Reference specifications and applications in the catalog; confirm order-specific requirements with your RFQ.
Decide where the mesh will serve, what it must look like and how many rolls the cutting layout needs. The comparisons and worked figures below turn those decisions into an orderable specification for an electro galvanized welded mesh roll.
Choose the protection route and delivery format first; a route label alone fixes neither service life nor strength. The linked references describe each process scope and are not certifications of the offered product.
| Product route | When to consider it | Confirm before ordering |
|---|---|---|
| Electro Galvanized Welded Mesh Roll | The installation is indoors, dry or sheltered, the grid stays visible and site-cut roll lengths suit the layout. | Coating route named in the order, acceptance evidence, wire-diameter basis, weld-area review and roll dimensions. |
| Hot-Dipped Galvanized Welded Mesh Roll | The exposure is wet, humid or long-term outdoor and heavier zinc coverage at the welds is a purchasing priority. | Welding and galvanizing sequence, coating acceptance requirement, finished dimensions and the evidence supplied with delivery. |
| PVC Coated Welded Mesh Roll | The project wants a colored polymer outer surface over a metallic-coated core for boundaries or light enclosures. | Core and coated diameters, underlying metallic coating, PVC requirements, finished opening and permitted joints. |
| Galvanized After Welded Mesh Panel | The work is organized around fixed infill dimensions and frames rather than site-cut roll lengths. | Panel width and height, edge projections, flatness, fixing layout and any fabrication after galvanizing. |
Begin with the job the electro galvanized welded mesh roll must do, then attach the details below to the selected specifications.
Approve the proposed electro galvanized welded mesh roll against the specification, and keep the sample reference with the quotation so receiving inspection uses the same basis.
Check opening and wire diameter with the stated method and units, and confirm roll width and length. Keep sample readings separate from catalog labels and record the dimensional limits.
Compare brightness and uniformity with the approved finish reference; inspect intersections and edges. Request the declared coating route and any agreed coating test evidence instead of reading performance from appearance.
Trial-fit a piece against the intended supports and fixings. Confirm edge treatment, roll identification and packing protection, then record revisions in the order documents.
Record discrepancies against the order before installation, cutting or mixing batches. Appearance alone does not settle cause or responsibility; use the agreed evidence.
| What you see | What to record | Purchasing or receiving step |
|---|---|---|
| Red rust at weld intersections or cut ends | Photograph the affected joints, identify the roll label and note how long and where the roll was stored. Check whether the site exposure matches the ordered coating route. | Compare with the approved sample and the agreed weld-area review. Obtain a disposition or repair procedure before installing affected sections. |
| White or grey powdery film on the bright surface | Note moisture, wrapping tightness, drainage and airflow in storage or transit; photograph the pattern and identify the rolls involved. | Wet storage stain develops on zinc kept damp without free airflow. Review storage history and surface condition, then agree cleaning, acceptance or replacement. |
| Opening or wire size does not match the quotation | Check the measuring direction and whether the figure is clear opening or pitch, base wire or finished diameter. Re-measure with the agreed method and units. | Resolve the basis difference in the supplier's dimensional record before cutting. Do not mix rolls measured on different bases. |
| Flattened rolls, scuffed finish or missing labels | Inspect wrapping, restraints and contact points; reconcile roll count and dimensions with the packing list and keep the labels. | Document condition on receipt with photos. Confirm replacement, repair or acceptance in writing before the rolls enter the works. |
Put exposure, dimensions and supply scope on the same footing before comparing prices for an electro galvanized welded mesh roll. The numerical items are assumed teaching figures, not offered specifications; the linked AGA guidance explains why coating and environment drive maintenance timing.
Specify an electro galvanized welded mesh roll by its steel grid, its electrolytic zinc requirement and the agreed acceptance evidence. A bright surface shows the finish, not a coating mass; where the coating is contractual, name the method, sampling and report in the order.
Material family: electro galvanized steel. Confirm the base-wire grade and the zinc requirement against the supplier's declaration and the purchase order.
Use this checklist when ordering an electro galvanized welded mesh roll; it lists what to agree with the supplier, not a universal tolerance schedule. ASTM B633 addresses electrodeposited zinc coatings, ASTM A90/A90M describes a coating-mass test, and EN 10223-4 covers welded mesh fencing scope. Confirm which requirements apply contractually and obtain product-specific evidence.
| Check item | Measurement basis | State in the RFQ | Evidence to agree |
|---|---|---|---|
| Coating route and requirement | Electrolytic zinc route named with the ordered acceptance requirement | Required route, any coating class or mass, and applicable standard editions | Supplier declaration plus specified coating test reports |
| Opening and pitch | Clear opening or centre-to-centre dimension in both grid directions | Nominal values, units, tolerances and measuring direction | Dimensional inspection record with sampling |
| Wire diameter basis | Base wire versus finished coated diameter | The basis, units and measuring method for the selected SKUs | Recorded readings against the agreed limits |
| Welds, edges and appearance | Intersection integrity, cut ends and surface against the approved finish sample | Visual acceptance basis, edge treatment and planned fabrication | Inspection record, approved sample reference and repair procedure |
| Rolls and packing | Width, length, quantity, roll identification and protection | Roll dimensions, labels and export packing requirements | Packing list, measurement record and shipment photographs |

Scope reference for electrodeposited zinc coatings, their classes and tests. Confirm applicability to welded wire mesh and obtain product-specific evidence.
