Wire Mesh
Expanded Metal Mesh
Expanded metal mesh is slit and stretched from metal sheet to form continuous diamond openings. It is used when a panel needs airflow, visibility, drainage and impact resistance without welded joints.
Buyer overview
Expanded Metal Mesh for Guards, Screens and Ventilation Panels
Expanded metal mesh is slit and stretched from metal sheet to form continuous diamond openings. It is used when a panel needs airflow, visibility, drainage and impact resistance without welded joints.
QY Metal Tech reviews drawings, sample photos, replacement dimensions and packing notes before quotation, so the supplied mesh can match the intended guard, screen, infill or cover panel.
Opening Pattern
Confirm SWD, LWD and whether the sheet should be raised or flattened.
Panel Fit
Send panel length, width, bearing direction, edge treatment and any frame or hole details.
Material & Finish
Confirm carbon steel, galvanized steel, stainless steel or aluminum with the required surface finish.
Packing Marks
List quantity, bundle groups, labels and destination so packing can follow the project sequence.
Applications
Where Expanded Metal Mesh is commonly used
Machine guards and safety panels
Open diamond panels help protect machinery while keeping visibility and airflow.
Ventilation and equipment screens
Raised or flattened mesh can be selected for equipment guards, vents and intake screens.
Walkway and stair infill panels
Cut-to-size panels can be reviewed for platform infill, stair sides and maintenance access.

RFQ guide
Confirm Opening, Strand and Panel Details
A faster quotation comes from clear opening data, strand dimensions, sheet or panel size, material, finish, quantity and destination. Photos or drawings are especially useful for framed panels and replacement work.
Standards reference
Standards and Finish References
- Expanded metal mesh should be reviewed by SWD, LWD, strand width, strand thickness, overall thickness, panel size and mesh direction.
- Raised and flattened mesh should be confirmed before production because surface height, handling feel and open area can change.
- Cut edges, welded frames, drilled holes and mounting details should follow approved drawings when the mesh is used as a guard or infill panel.
- Finish references such as mill finish, hot-dip galvanizing, painting or powder coating should match the service environment and buyer inspection documents.
Specification examples
Common Expanded Metal Mesh RFQ Expressions
| SWD x LWD opening | Short way and long way opening dimensionsUse SWD and LWD to review the diamond pattern before pricing. |
|---|---|
| Raised or flattened sheet | Raised or flattened surface routeConfirm before quotation because thickness and handling feel differ. |
| Strand width x thickness | Strand width and thickness dataKey reference for strength, open area and panel weight comparison. |
| Framed guard panel | Framed guard panel with fixing detailsConfirm welded frame, holes or mounting points from the drawing. |
Use these examples as RFQ shorthand, then confirm final dimensions, load, material, finish and drawings before production.

Include SWD/LWD, strand width, sheet thickness, raised or flattened type, panel size, material, finish, quantity and destination. Drawings or old panel photos help us avoid edge and fit-up mistakes.
FAQ
Expanded Metal Mesh questions before inquiry
What is the difference between raised and flattened expanded metal?
Raised expanded metal keeps the original three-dimensional strand shape after stretching. Flattened expanded metal is rolled flatter when a smoother surface or more controlled thickness is needed.
What dimensions are needed for an expanded metal mesh quote?
Send SWD, LWD, strand width, strand thickness or sheet thickness, panel length and width, raised or flattened type, material, finish and quantity.
Can expanded metal mesh be framed or cut to size?
Yes. Expanded metal can be cut, framed, drilled, welded or finished according to drawings and installation requirements.
Specification guide
Expanded Metal Mesh Specification and Walkway Selection
Expanded metal mesh should be specified by material, raised or flattened form, opening direction, strand size, sheet size, finish and the actual application. For walkway or stair use, also send the support layout, traffic condition, edge treatment and project approval basis.
Fields to put on the inquiry or drawing
| Field | What to confirm |
|---|---|
| Application | Walkway mesh, machine guard, screen, ventilation panel, infill or fabrication blank. |
| Material and form | Material grade or project wording; raised or flattened expanded metal. |
| Opening direction | SWD and LWD orientation on the finished sheet or part drawing. |
| Strand geometry | Strand width, strand thickness and the measurement convention used. |
| Finished format | Sheet or cut-piece size, quantity by size, edge condition, cutouts and fabrication scope. |
| Finish and environment | Mill finish, galvanized, painted or project-specified finish with indoor or outdoor context. |
| Walkway review | Clear support span, support direction, pedestrian or maintenance use, fixing and required project approval. |
| Commercial details | Quantity, packing marks, destination, drawings and any inspection document request. |
Terminology: SWD is the short way of the opening and LWD is the long way of the opening. Raised and flattened forms should not be assumed interchangeable because flattening changes the final geometry and surface form.
Use the opening and strand-size guide, compare raised vs flattened expanded metal, or review expanded metal vs perforated sheet. When the fields are ready, send the drawing and RFQ to QY.
QY reviews the submitted product, dimensions, quantity, finish, packing and destination before quotation. Walkway suitability, guarding performance and local compliance require the project-specific review and approval stated by the buyer.
