Product Introduction
Perforated metal filter with small holes is made by punching uniform tiny holes on metal sheets, then formed into tubes, discs or other filter shapes. It works as a basic filter medium to block solid particles from liquids, gases and slurries. This filter is simple in structure and stable for general separation tasks.

Properties
Rigid structure, good impact resistance, stable hole size, easy shaping, recyclable, moderate corrosion resistance based on material selection
Features
1. Regular and neat hole layout, consistent filtering area
2. Hard metal plate, not easy to tear under normal medium impact
3. Can be rolled, welded and processed into various filter shapes
4. Low cost compared with wedge wire filter for coarse and medium filtration
5. Simple surface, convenient for cleaning
6. Good air permeability and liquid passing capacity

FAQ
Q1: Can you punch holes smaller than 0.5 mm?
A1: Yes, we can make micro small holes, but the minimum hole size is limited by plate thickness. Send us your drawing for confirmation.
Q2: What material should I pick for acidic liquid?
A2: 316L stainless steel is recommended for weak acid conditions. For strong corrosive media, we suggest choosing other filter types.
Q3: Can you make perforated filter cylinders?
A3: Sure. We roll perforated sheets into tubes and weld seams as required. Flange and thread ends are available.
Q4: Are samples available?
A4: Samples can be arranged. Sample cost and freight will be discussed separately.
Q5: How to clean perforated metal filters?
A5: Use high-pressure water or air blowing. Stubborn dirt can be soaked and brushed gently. Avoid strong acid that damages the material.
Q6: What is your lead time?
A6: Standard material sheets can be shipped fast. Custom punching and forming usually take 15-20 days, depending on quantity and difficulty.
