Expanded metal filters, also referred to as expanded mesh filter cylinders, are manufactured from expanded metal sheets. Common structural types include both longitudinal welded pipes and spiral welded pipes. The expanded metal is slit and stretched using punching machines to create various hole patterns, resulting in a product with a robust structure that maintains its shape over time without deformation. As a result, expanded metal cylindrical filters offer greater rigidity and durability compared to wire mesh filter tubes.
Standard specifications include diameters ranging from 10 mm to 300 mm and lengths of up to 3 meters. These expanded mesh tubes are typically made from materials such as aluminum, galvanized steel, or stainless steel.
Characteristics of Metal Expansion Mesh
Expanded metal mesh, also known as expanded metal or stretched metal, is a mesh material that is precision-cut and stretched from a single piece of sheet metal. It is not woven or welded together, and its most notable feature is the absence of welds and waste, resulting in a unique diamond-shaped mesh structure.
APPLICATION SCENARIOS
Expanded metal mesh is widely used across a variety of fields—from heavy industry to modern architecture—due to its integral weld-free structure, lightweight yet high-strength properties, excellent anti-slip performance, and good permeability.
In construction, it serves as decorative curtain walls, interior partitions, and ceiling panels. Within industrial applications, it provides ideal nonslip flooring for factory platforms, walkways, and ship decks. It also functions as an efficient filter and screen in mining and chemical processing.

Frequently Asked Questions
What materials are available for expanded metal filters?
Expanded metal filters are typically manufactured from high-quality aluminum, galvanized steel, or stainless steel to ensure durability and corrosion resistance.
How does expanded metal differ from traditional wire mesh?
Unlike woven wire mesh, expanded metal is precision-cut and stretched from a single sheet. This creates a weld-free, integral structure that offers superior rigidity and maintains its shape without deformation.
What are the common applications for this mesh?
It is widely used for industrial filtration, machinery protective covers, nonslip flooring for walkways, decorative architectural panels, and safety enclosures in construction.
Can the dimensions be customized?
Yes, we provide standard diameters ranging from 10 mm to 300 mm and lengths up to 3 meters. Specific thickness and strand widths can also be selected based on technical requirements.
What is the advantage of the fish scale or diamond hole shape?
These shapes provide excellent permeability for air and fluid flow while maintaining high structural strength and anti-slip properties, making them ideal for industrial platforms and filters.
Is the surface treatment weather-resistant?
Yes, treatments like hot-galvanizing provide a thick, protective zinc coating that is highly resistant to rust and suitable for outdoor or harsh industrial environments.
