Expanded metal filters are made from a combination of flattened, regular and/or corrugated expanded aluminum, galvanized steel or stainless steel and regular or corrugated screen wire.

Expanded metal filters are used mostly in commercial, industrial and OEM facilities. They are used for a variety of applications including heating, air conditioning and other hvac requirements, grease filters, oil or water mist control, large particulate collection or heavy particulate collection, areas where filters are exposed to outside weather conditions, barriers to intrusion of debris, insects or animals, conditions where maximum air flow is required and small particle control is not the primary concern.
