Decorative Metal

Expanded Metal

Expanded Metal

Lightweight, durable decorative metal cut and stretched from a single sheet.

Expanded metals are materials obtained by cutting metal sheets in a specific pattern and then stretching them to expand. As a result of this process, the metal sheet acquires a larger surface area and gains a mesh or lattice structure. Expanded metals are generally used in various industrial, commercial and architectural applications.

Key features

  • Single piece, zero waste
  • High strength at low weight
  • Air & light permeability
  • Anti-slip, walkable surface

Properties of expanded metal

Durability: Expanded metals retain the durability properties of the metal they are made from. This makes them suitable for various applications.

Light weight: When the metal sheet is expanded, the material covers a larger surface area without increasing in weight. This makes expanded metal lightweight.

Air and light permeability: Thanks to their perforated and open structure, expanded metal structures allow air and light to pass through.

Slip resistance: Expanded metal surfaces increase slip resistance, providing a safe walking or working surface.

Aesthetics: Since it can be produced in different patterns and materials, it can be used for aesthetic purposes.

Production process

Expanded metal production consists of the following steps:

Cutting: The metal sheet is cut in a specific pattern. This cutting process usually creates a series of connected holes or slits.

Expanding: The cut sheet is stretched and expanded. This expansion process increases the surface area of the metal sheet and gives it its characteristic mesh structure.

Areas of use

Construction and architecture: Used in facade cladding, railings, fences, stair treads and decorative panels.

Industry: Common in industrial applications such as filters, gratings, walking platforms and safety barriers.

Automotive and transport: Used in vehicle components such as ventilation, radiator guards and luggage compartments.

Furniture and design: Featured in modern furniture designs and various decorative objects.

Material types

Expanded metals can be produced from different metals. Commonly used materials include steel, aluminium, stainless steel, copper and titanium. Which material is used depends on the requirements of the application.

Expanded metals are versatile and functional materials, used across a wide range in modern design and engineering. By offering both practical and aesthetic advantages, they play an important role in various industries.
