Expanded Metal or Perforated Metal? How to Choose?

Available Materials

Heyou provides professional and reliable service.

Materials Overview: Both expanded and perforated metals are available in materials such as aluminum, stainless steel, plain steel, galvanized steel, copper, and brass.

Manufacturing Methods:

Expanded metal is created through cutting and stretching or flattening, while perforated metal is produced via stamping or laser cutting techniques.

Waste Management:

Expanded metal generates little to no scrap, whereas perforated metal can create scrap depending on the size and frequency of the holes.

Cost Considerations:

Generally, the cost of expanded metal is lower in comparison, while perforated metal tends to have a mid to high price range depending on customization.

Hole Shapes:

Expanded metal typically features diamond-shaped holes, hexagonal holes, or near-elliptical shapes, while perforated metal can accommodate a variety of shapes including round, square, slotted, and hexagonal designs, allowing for a greater range of customizability.

Structural Strength and Stability:

Expanded metal excels in structural integrity and stability, whereas perforated metal offers general structural support.

Design Flexibility:

Expanded metal allows for the creation of 2D or 3D patterns by adjusting the style, size, and arrangement of holes, while perforated metal can produce intricate 2D patterns including customized designs such as text and images.

Durability:

Both types can achieve heightened durability, with expanded metal relying on corrosion-resistant materials, often enhanced by surface treatment.

Sustainability:

Both expanded and perforated metals utilize environmentally friendly and recyclable materials.

Architectural Applications:

Expanded metal is suitable for applications such as stair treads and walkways requiring load-bearing capacity, while perforated metal is commonly found in building facades, fences, sunshades, and room dividers.

Other Uses:

Applications for expanded metal include filtration, sieving in food processing, speaker grilles, and automotive components, while perforated metal is favored in decoration for both indoor and outdoor settings.
