The fine perforated metal sheet uses small, closely spaced punched holes where a coarse opening would admit too much material. Air, sound or selected particles can pass through the perforated field. Metal remaining between the holes joins the field into a continuous sheet, with a solid perimeter for mounting to a housing or frame. The blank may stay flat or receive cutting and forming to suit the finished part. Diameter, pitch and thickness need to be considered together because the punching process must suit their combination. These sheets serve compact screening faces, ventilation covers and acoustic-facing components.

Main Applications
The fine perforated metal sheet supplies finer screening faces for compatible process equipment.
01
Compact ventilation covers can use small openings while retaining a solid fixing border.
02
Acoustic panels expose the backing material through a closely repeated hole field.
03
Small openings are useful on covers where a wide grid would expose the area behind the panel. A framed micro-hole face can keep its overall outline firm while dividing the passage area into closely repeated openings.
04
Why choose us
For fine perforated metal sheet, our workshop reviews the hole field with the panel thickness and later fabrication. Hebei Eryang can supply cutting, bending, rolling and welding alongside punching. Buyers can therefore coordinate a fine-opening blank with the required finished shape. The solid margins and fixing locations are kept on the same drawing, reducing ambiguity when the screen is prepared for its frame or housing.
The drawing should distinguish the perforated working area from the outside panel size, particularly where a frame will cover part of the margin.
FAQ
Q: Can the micro-hole diameter be 0.5mm?
A: Yes. That is the starting diameter in the listed range.
Q: Can stainless material be specified?
A: Yes. The material range includes 304 and 316L stainless steel.
Q: Can every small-hole pattern be used with every thickness?
A: No. The hole and sheet combination must suit the punching process.
