Micro Expanded Metal Roll

A micro expanded metal roll is a fine, lightweight version of expanded metal that is produced by slitting and stretching very thin sheets of metal, such as stainless steel, aluminum, or copper, into a continuous mesh with extremely small openings. Unlike standard expanded metal, the micro type has a delicate structure with precise and uniform apertures, often resembling a fine wire mesh but with the strength of a single-piece sheet. It is usually supplied in rolls for easier handling, storage, and installation. Micro expanded metal is widely used in applications that require filtration, shielding, or reinforcement. Common uses include air and liquid filters, battery electrodes, speaker grilles, EMI/RFI shielding, precision screens, and protective covers in electronics and medical devices. Its excellent strength-to-weight ratio, flexibility, and corrosion resistance make it suitable for both industrial and commercial uses. With high open area and fine mesh size, micro expanded metal rolls provide effective airflow, drainage, and conductivity, while maintaining durability and long service life.

What Is A Micro Perforated Plate Used For

A micro perforated plate is a thin metal sheet that contains a high density of very small, precisely punched or laser-drilled holes. This unique structure makes it highly functional in applications that require airflow, sound absorption, or filtration while maintaining mechanical strength. One of the most common uses is in acoustic engineering, where micro perforated plates act as sound-absorbing panels in walls, ceilings, silencers, and ventilation systems. The tiny holes create a Helmholtz resonance effect that dissipates sound energy, providing excellent noise control without the need for traditional fibrous materials. In addition, micro perforated plates are widely used in filtration and separation systems, where they serve as fine sieves for liquids, gases, or powders. Their precise perforations ensure uniform flow and reliable particle control. They are also employed in architectural design, adding both functional acoustic benefits and aesthetic appeal in modern facades or interior elements. Made from materials like stainless steel or aluminum, these plates offer durability, corrosion resistance, and long service life. With customizable hole sizes, patterns, and thicknesses, micro perforated plates are versatile solutions for industries such as construction, automotive, aerospace, and environmental engineering.
