Applications
Perforated metals are used in interior and exterior design
manufacturing applications (both functional and decorative).
Industries that make use of perforated metals include filtration,
insulation, security and barrier, construction, furniture,
acoustics, material development, automotive engineering, chemical
and energy, food service, waste management and automotive
engineering. The number one industry for perforated metals is
architectural design.

Benefits
Perforated metal services offer so many stand-alone and “as
compared to” benefits. First, perforated metals and generally
lightweight and easy to transport and handle. Second, they’re
incredibly versatile, more so than competitors like expanded metal.
Likewise, they can be produced with unmatched precision. In
addition, they are extremely functional and feature incredible
strength and structural integrity.
They’re also sustainable in a number of ways. For instance, old
perforated metal components, scraps and leftover metal from
production can be recycled and refurbished. Also, unlike others,
old acoustic perforated metal sheet can be cleaned and refurbished
without damage to acoustic equipment absorptive properties. They
additionally provide great energy savings to the architectural
industry—When integrated in a building facade, they account for an
energy savings of up to 25%.
