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
Expanded Metal for Different Loads and Surfaces
Choose the profile, opening and sheet condition around structural demand, visual intent and downstream fabrication.

Standard Raised Expanded Metal
An offset strand profile with pronounced texture, grip and structural depth.

Flattened Expanded Metal
Cold-rolled after expansion to create a smoother and more uniform sheet surface.

Architectural Expanded Metal
Pattern and finish combinations for facades, ceilings, partitions and solar-control screens.

Heavy-Duty Expanded Metal
Thicker strands and larger sections for guards, access platforms and demanding assemblies.

Micro Expanded Metal
Fine diamonds for filtration supports, battery components, vents and precision screening.

Expanded Metal Grating
Load-oriented meshes with slip-resistant surfaces for walkways, stairs and service platforms.
EXPANDED METAL PRODUCTS

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 |
APPLICATIONS
Open Metal for Buildings and Industry
Expanded metal moves between architectural and industrial roles through the choice of material, diamond and strand profile. Application images are AI concepts, not completed AMBER projects.

Architectural Facades
Ventilated skins, screening panels and expressive building envelopes.

Walkways and Platforms
Open access surfaces for industrial circulation and maintenance zones.

Machine Guards
Protective panels that maintain visibility and airflow around equipment.

Ventilation Screens
Durable covers for air movement, plant rooms and service openings.

Interior Partitions
Open screens for zoning spaces while preserving light and visual connection.

Racks and Industrial Components
Fabricated mesh parts for storage, support and process equipment.
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.

MANUFACTURING CAPABILITY
Built on Controlled Production
AMBER combines established manufacturing resources with product-specific review for expanded metal orders, from incoming material and production setup to fabrication coordination and export packing.

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.
