Aluminum Expanded Metal Specifications

Available aluminum expanded metal sheet specifications. Choose diamond pitch, base metal thickness and strand width, with standard or custom sheet dimensions.

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.

SWD and LWD represent the short way and long way of the diamond pitch, measured center-to-center between corresponding bond centers. These dimensions are mesh pitch values, not clear opening dimensions. Actual clear openings depend on strand width and mesh geometry. Mesh dimensions, base metal thickness and strand width are in mm; sheet size is in m.

Product overview

What Is Aluminum Expanded Metal?

Aluminum expanded metal is produced by slitting and stretching aluminum sheet into a continuous diamond opening pattern. The resulting aluminum expanded metal mesh provides low weight, ventilation and visibility without welded joints. Corrosion performance depends on the alloy, finish and exposure conditions.

YueChu Metal supplies custom aluminum expanded metal sheets for facades, ceilings, decorative screens, sunshades, infill panels, ventilation panels and lightweight industrial fabrication. Compare product families in our expanded metal overview.

Applications of Aluminum Expanded Metal

An aluminum expanded metal facade or sunshade requires agreement on panel geometry, support details, alloy and finish. Interior aluminum expanded metal panels are also used for ceilings, partitions and decorative screens.

Surface Finishes for Aluminum Expanded Metal

Options for review include mill finish, anodized aluminum expanded metal, powder coated aluminum expanded metal and PVDF finishes. Confirm color, exposure, coating requirements and treatment after fabrication before ordering.

Alloy selection

Which Aluminum Alloy Is Suitable for Expanded Metal?

The selection of aluminum alloy for expanded metal depends on the required mechanical properties, forming requirements, corrosion exposure and final application.

Common alloy options include:

1060 Aluminum: Commercially pure aluminum for applications where high alloy strength is not the primary requirement.
3003 Aluminum: An aluminum-manganese alloy commonly considered for general fabrication and architectural applications.
5052 Aluminum: An aluminum-magnesium alloy considered for applications requiring a combination of strength and corrosion resistance.
6061 Aluminum: A heat-treatable aluminum alloy used in applications requiring higher mechanical strength.

The suitable alloy and temper should be confirmed according to the forming process and project requirements. When requesting 1060, 3003, 5052 or 6061 aluminum expanded metal from YueChu Metal, include the required alloy and temper for review; a grade name alone does not confirm that a particular mesh geometry can be manufactured.

Surface profiles

Difference Between Raised and Flattened Aluminum Expanded Metal

Raised aluminum expanded metal

Raised aluminum expanded metal retains the angled strands formed during slitting and stretching.

Flattened aluminum expanded metal

Flattened aluminum expanded metal is rolled after expansion to produce a lower, smoother profile.

Flattening can change strand dimensions and opening geometry. Specify the required profile and finished dimensions; base sheet thickness and overall raised mesh thickness are different measurements. Strength and stiffness depend on alloy, temper, strand geometry, orientation and support conditions.

Use the expanded metal weight and open area calculator for preliminary comparison, then confirm the final specification with YueChu Metal.

Specification & ordering

What Information Is Needed to Order Aluminum Expanded Metal?

For an aluminum expanded metal quotation, send YueChu Metal the alloy and temper, raised or flattened profile, diamond pitch, strand dimensions, finished sheet or panel size, finish and quantity.

Alloy and temper: Identify the grade and any required material documentation.
Mesh geometry: Give SWD and LWD, strand width and base metal thickness. Identify whether dimensions are bond-center pitches or clear openings.
Finished panels: Specify width, length, diamond orientation, edge conditions, tolerances and any cutting or framing details.
Finish and exposure: Include mill finish or coating type, color reference and intended environment.
Order and delivery: State quantity, application, packing needs and destination port or country.

Attach a drawing or reference sample when available. A market style number alone is not a complete aluminum expanded metal sheet specification.

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.
