Choose the alloy, opening pattern, panel size, and finish for your architectural, fabrication, or OEM project. Drawings and samples are welcome for fast quotation review.

Expanded Metal Specifications & Dimensions

Compare reference patterns used in the USA, UK, Germany, France and Australia. Confirm material, finished dimensions and availability for your order.

For accurate quotation and production, expanded metal mesh should be measured by SWD (Short Way of Diamond), LWD (Long Way of Diamond), strand width, sheet thickness, sheet width, and sheet length. These expanded metal mesh specifications directly affect opening size, weight, strength, ventilation rate, and application performance.

When sending an inquiry for aluminum expanded metal, include these measurements for faster quotation and production.

Pitch ≠ clear opening. Diagram labels: TL = short way, TB = long way, b = strand width, d = metal thickness, B = sheet width and L = sheet length. Specify whether the short and long dimensions on your drawing are bond-center pitches (SWD / LWD) or clear openings (SWO / LWO).

LWD × SWD: Long × short way of the diamond pitch, measured between corresponding bond centers.
Strand width & thickness: Strand width is w; base metal thickness is t. Raised overall thickness T is a separate dimension.
SWO / LWO: The short and long dimensions of the clear opening between strands; these are smaller than the corresponding diamond pitches.
Open area & sheet size: Open area is the percentage occupied by openings. Sheet size is the overall width and length; specify diamond orientation separately.

All dimensions are in mm. LWD and SWD are the long and short diamond pitches, measured between corresponding bond centers. ≈ indicates an approximate value. Scroll horizontally to compare all fields.

Product overview

What Is Aluminum Expanded Metal?

Aluminum expanded metal is produced by slitting and stretching aluminum sheet into a continuous diamond opening pattern. It provides low weight, corrosion resistance, ventilation, visibility, and a clean architectural appearance without welded joints.

YueChu Metal supplies custom aluminum expanded metal sheets for facades, ceilings, decorative screens, sunshades, infill panels, ventilation panels, lightweight enclosures, and industrial fabrication.

Lightweight structure for architectural and industrial projects.
Good corrosion resistance for indoor and outdoor applications.
Custom alloys, opening patterns, sheet sizes, and edge conditions.
Anodized, powder coated, PVDF coated, and mill finish options.

Applications of Aluminum Expanded Metal

Common applications include building facades, ceiling systems, decorative screens, sunshade panels, infill panels, ventilation panels, lightweight enclosures, and fabricated architectural components.

How to Choose the Right Alloy and Finish

Select the alloy according to forming, strength, and corrosion requirements. Anodized, powder coated, and PVDF coated finishes are often specified for visible or outdoor architectural projects.

Expanded Metal Manufacturing & Customization

A slit-and-stretched sheet, configured around your project.

Slitting and stretching turn solid sheet into connected mesh. Raised mesh retains angled strands; rolling creates a smoother, flattened profile. Cutting, forming and finishing follow your agreed specification.
