Elevating expanded metal through Architectural designs. With exceptional performance characteristics, high strength-to-weight ratio, and environmentally friendly manufacturing process, expanded metal offers architects and designers a versatile material capable of delivering both function and visual impact.

To put further light on expanded metal’s multifaced uses, here are three of the many architectural applications:

Expanded Metal FacadeFaçades: The Building Envelope

Façades are probably the most recognized application due to its popularity, and identifiable use as a building’s envelope. The openness creates a unique look against the skyline–especially if color is added. The angle of the strands can also provide privacy and shade while simultaneously allowing outward views. This balance of aesthetics and utility is a key reason expanded metal facades continue to rise in popularity.

Stairs and Infill Panels: Safe and SoundArchitectural Expanded Metal- Stairs and Balcony
Design solutions that are safe and stunning. The raised openings provide excellent traction to prevent slips for safety corridors, rooftop walkways, scaffolding, industrial catwalks, and stairs.

Architectural Expanded Metal- Living WallDecorative Accents: Beyond the Expected
Expanded metal’s pattern uniformity is perfect for creative accents that can complement modern architectural elements. Its possibilities extend beyond the building envelope into light features, signage, room partitions, indoor living walls, office accessories and more. Its adaptability makes it a go to material for designers seeking texture and consistency.

ADVANTAGES OF EXPANDED METAL FOR ARCHITECTURE
There are many additional uses for architectural expanded metals. Also known as Architectural or Decorative Mesh, it is both lightweight and incredibly strong. It’s made from a sheet of metal, and there are no joints or welds that can separate.

Offering both durability and decorative versatility, the material’s pattern uniformity and high strength-to-weight ratio allows for innovative, lasting applications across your projects. With material options including steel, aluminum, copper and beyond, expanded metal offers both form and function. Plus, the manufacturing process is highly efficient, featuring near-zero waste which may help you earn LEED credits. This efficiency is complemented by the ability to add optional surface treatments such as paint or powder coat to prolong its lifecycle while adding a splash of color.
