HIGH-STRENGTH OPEN METAL

Expanded Metal

Slit and stretched from solid sheet, expanded metal combines strength, ventilation and continuous open area for architecture, access systems, guarding and industrial fabrication.

EXPANDED METAL SOLUTIONS

Continuous Mesh Formed Without Welding

Expanded metal is produced by slitting and stretching sheet into a rigid network of connected strands. The process creates ventilation and visibility while preserving continuity across the panel. AMBER reviews diamond size, strand dimensions, sheet thickness, finish and fabrication around the intended use.

PRODUCT ADVANTAGES

Efficient Structure, Practical Performance

Expanded metal creates a robust open surface with clear architectural and industrial benefits.

01

Strength-to-Weight Efficiency

The connected strand structure provides rigidity while retaining an open, economical panel format.

02

Controlled Air and Light

Diamond geometry can be selected around ventilation, shading, visibility and screening targets.

03

Continuous Construction

The mesh is expanded from one sheet, avoiding welded intersections within the opening pattern.

04

Fabrication Flexibility

Panels can be planned for cutting, leveling, forming, framing and suitable surface finishes.

MAIN PRODUCT TYPES

OPENING PATTERNS AND SPECIFICATIONS

Define the Diamond Before Production

Share the required SWD, LWD, strand width, thickness, sheet condition, panel size and finish. If the specification is incomplete, AMBER can review it against the application.

Specification What It Defines Common Options
SWD Short way of diamond Project-defined
LWD Long way of diamond Project-defined
Strand Width Width of the metal strand Project-defined
Strand / Sheet Thickness Material gauge and finished profile Project-defined
Sheet Condition Raised or flattened surface Raised / Flattened
Panel Size and Finish Delivery format and surface treatment Cut sheet / Custom panel / As specified

CUSTOM MANUFACTURING

Panels Prepared for Your Assembly

AMBER can review custom diamond sizes, sheet dimensions, blank areas, orientation, cutting, leveling, bending, framing and finish requirements from project drawings. Production details are confirmed before release so the expanded pattern works with fixing points and fabricated edges.

STOCK AND CUSTOM PRODUCTION

A Supply Route Matched to the Order

Availability depends on material, pattern, dimensions, finish and quantity. Confirm the specification before relying on stock status or lead time.

01

Standard Specification Supply

Established material and mesh combinations can be reviewed for repeat requirements and practical lead times.

02

Project-Specific Production

Custom diamonds, thicknesses, panel sizes and fabrication details are assessed from drawings and quantity.

03

Packing by Delivery Format

Sheets and fabricated panels can be identified and packed around handling and export requirements.

FREQUENTLY ASKED QUESTIONS

Expanded Metal Planning Questions

Use these answers as a starting point, then share the project drawing for a specification review.

Raised mesh retains the offset profile created during expansion. Flattened mesh is rolled after expansion for a smoother and thinner surface.

Provide SWD, LWD, strand width and thickness together with the required panel size and diamond orientation.

Yes. Cutting, edge treatment, bending and framing can be reviewed, but fixing zones and pattern orientation should be defined early.

The answer depends on base metal, exposure and appearance. Galvanizing, powder coating, anodizing and stainless steel options can be reviewed.

Samples can be discussed after the material, diamond pattern, thickness and surface condition have been narrowed down.
