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
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.

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 × LWD design spacing | Short- and long-direction spacing between corresponding points of adjacent diamonds; specify clear openings separately as SWO/LWO. |
|---|---|
| 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.

FAQ
Expanded Metal Mesh questions before inquiry
What do SWD and LWD mean?
SWD and LWD describe the short- and long-direction diamond design spacing, measured between corresponding points of adjacent diamonds. Clear openings are SWO and LWO. Specify the measurement basis on the drawing; do not treat design spacing as the clear gap.
Raised or flattened expanded metal: which one?
Raised mesh keeps the three-dimensional strand shape after stretching. Flattened mesh is rolled for a smoother surface and more controlled thickness; the two are not interchangeable.
How do I specify expanded metal mesh?
Send SWD, LWD, strand width, strand or sheet thickness, raised or flattened form, sheet or panel size, material, finish and quantity.
Which materials are available?
Carbon steel, galvanized steel, stainless steel or aluminum, with mill, galvanized, painted or powder-coated finish.
Can expanded metal be cut, framed or drilled?
Yes. Panels can be cut to size, framed, drilled, welded and finished according to your drawings.
Expanded metal or perforated sheet: which suits my project?
Expanded metal is a one-piece diamond mesh with good airflow and impact resistance, often used for guards, screens and walkways. Perforated sheet suits projects that specify a hole shape, pattern and open area, such as facades and acoustic panels.

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/LWD identify diamond design spacing; SWO/LWO identify clear opening dimensions. Confirm whether quoted values describe design spacing or clear openings. Raised and flattened forms should not be assumed interchangeable because flattening changes the final geometry and surface form. NAAMM EMMA 557-25, Terminology (English PDF).
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.

Factory verification and order terms
Video factory visits by appointment
Video factory visits can be arranged in advance. Contact our sales team to agree a time, platform and accessible production, inspection or packing areas. Other customers’ information and confidential areas are not shown.
Lead time: usually 30 days ex-works

Trade terms are agreed for each order and logistics arrangement. The written quotation specifies the applicable Incoterms® 2020 rule, named delivery place or port of shipment, and whether freight, insurance and taxes are included. For containers handed to a carrier before vessel loading, FCA is considered rather than automatically using FOB.
Quality concerns and corrective action
Please provide the order number, affected quantity, photos or video, and relevant measurements or inspection records when reporting a quality concern. If responsibility is confirmed to lie with us, a remedy such as repair, additional supply, replacement, refund or price adjustment is agreed under the contract. Costs and the action plan are confirmed in writing; no unconditional return or fixed resolution period is promised.
