Expanded metal infill panel is manufactured by slitting and stretching metal sheet with a die to create different shaped holes in one step. It can be expanded up to 10 times its original size, creating a product that weighs about 80% less while retaining its fundamental rigidity and integrity.
Expanded metal infill panels are mainly made of stainless steel, aluminium and low carbon steel. They are available as raised expanded metal, where sharply angled knuckles remain where the individual strands meet, and flattened expanded metal, which undergoes an additional cold rolling process to create a smoother surface.
Expanded metal provides structural and economical benefits because it is formed from a single piece of metal with no welds or weak points. Unlike perforated metal, there is no material waste during production, making it suitable for railings, partitions, protection and decoration.
Expanded metal infill panels combine durability, attractive patterns, ventilation and lightweight construction for indoor and outdoor architectural applications.
Corrosion-resistant material options provide an excellent weight-to-strength ratio.
Various hole patterns and finishes provide flexible architectural and decorative options.
The panels can be cut and sheared for application-specific sizes and installation requirements.
Openings permit free flow of light, heat, sound and air.
The expanded structure provides low weight while retaining rigidity and structural integrity.
Choose raised expanded metal with angled knuckles or flattened expanded metal with a smoother surface.
Expanded metal infill panels are available in multiple materials, hole shapes, surface treatments and dimensions for architectural, protective and decorative applications.

Expanded metal infill panels are used indoors and outdoors in a wide range of structural, protective, partition and decorative applications.
Expanded metal infill panels offer a sound one-piece structure, efficient material usage and flexible architectural applications.
Raised expanded metal is pressed, cut and expanded, leaving sharply angled knuckles where the individual strands meet.
Flattened expanded metal undergoes an additional cold rolling process, creating a smoother surface and a finished product that is about 5% lighter than raised expanded metal.
The panel is formed from a single piece of metal with no welds or weak points, providing a structurally sound construction.
Unlike perforated metal, there is no waste in the production process, making expanded metal an economical option for suitable applications.
