Expanded Metal Overview
Expanded metal is produced from a solid metal sheet that is simultaneously slit and stretched to create an open mesh structure.
Unlike welded or woven mesh products, expanded metal is formed from a single piece of metal without welded joints, providing a strong, lightweight and versatile solution.
With different opening patterns, strand dimensions and material options, expanded metal can be customized for applications including machine guards, security barriers, flooring, architectural panels and industrial fabrication.

Expanded Metal vs Perforated Metal
Expanded metal and perforated metal are both open metal products, but their manufacturing processes and applications are different.
| Comparison | Expanded Metal | Perforated Metal |
|---|---|---|
| Manufacturing | Metal sheet is cut and stretched | Holes are punched into sheet metal |
| Structure | Continuous mesh structure | Individual openings |
| Strength | Higher rigidity due to connected strands | Depends on sheet thickness and hole design |
| Opening Design | Diamond or customized mesh patterns | Round, square, slotted and custom holes |
| Main Advantages | Strength, airflow and lightweight structure | Precise open area and appearance control |
| Typical Uses | Guards, screens, flooring and fabrication | Filtration, panels, ceilings and facades |
Choose expanded metal when structural strength and mesh performance are important.
Choose perforated metal when precise openings and controlled open area are required.
Case Study: Expanded Metal Facade Panels for Commercial Building
Project Background
An architectural contractor required custom expanded metal panels for the exterior facade of a commercial building.
The project needed a lightweight metal solution that could provide ventilation, partial shading and a modern architectural appearance.
Project Requirements
The customer required:
- Custom expanded metal patterns
- Consistent panel appearance
- Outdoor durability
- Easy installation with existing facade structures
Manufacturing Solution
Aluminum expanded metal was selected because of its lightweight properties, corrosion resistance and suitability for architectural applications.
The panels were manufactured with customized mesh specifications and cut into required sizes according to the building design.
A protective surface finish was applied to improve outdoor durability and maintain a consistent appearance.
Quality Inspection
Before shipment, each panel was inspected for:
- Mesh pattern consistency
- Panel dimensions
- Surface finish quality
- Edge condition
Protective packaging was used to prevent damage during transportation and installation.
Application Result
The finished expanded metal facade panels provided a balance of aesthetics, ventilation and structural performance.
The solution was successfully integrated into the building exterior while achieving the required architectural design effect.
Expanded Metal FAQs
