Product Introduction
Stainless steel perforated metal filter is made by punching regular holes on stainless steel sheet, then cut, bent, rolled or welded into filter tubes, discs, baskets and other filter shapes. It is a common industrial filter component for intercepting solid impurities in liquid, gas and powder media. Compared with woven mesh, it has stable hole size and better structural rigidity.
Properties
Good structural rigidity, stable aperture, corrosion resistance, high temperature resistance, easy forming, reusable after cleaning, good pressure bearing capacity.
Features
1. Consistent punching aperture, stable filtering effect
2. Solid plate base, not easy to tear under medium impact
3. Multiple hole patterns and plate thickness options to match different flow and interception needs
4. Can be rolled, bent and welded into various shapes
5. Simple surface treatment, easy to clean repeatedly
6. Low cost for conventional specifications, suitable for coarse and medium filtration
Application Scenarios
Water treatment: pipeline pre-filtration, tank internal impurity interception, circulating water filtration
Chemical industry: chemical liquid filtration, gas dust removal, chemical filler support
Food and beverage: raw material filtration, protective filter for food equipment
Pharmaceutical industry: coarse filtration of medicinal liquid, material support
Machinery industry: oil filter, air filter, hydraulic system impurity blocking
Mining and environmental protection: dust collection, sludge preliminary filtration
Other: ventilation and sound insulation, powder screening, seawater pretreatment
Product & Company Advantages (Anping Haopeng Metal Wire Mesh Co., Ltd.)
Based in Anping, China’s wire mesh hometown, we make perforated metal filters in-house from plate punching, forming, welding to finishing.
We adjust hole size, plate thickness and product shape according to customer drawings or working conditions. Both small trial batches and bulk orders are acceptable.
We check aperture, welding strength and dimension before shipment to keep quality consistent.
Our team gives practical selection suggestions for filtration projects. We keep steady lead time and arrange priority production for urgent orders.
We support third-party inspection if required and export our products to overseas markets.
Customer Feedback
Many buyers tell us the hole size of our perforated filters stays uniform, and there are almost no deformed or missed holes.
Customers using them for pipeline pre-filtration say the filters hold up well and do not break easily under continuous flow impact.
Equipment manufacturers mention we can quickly adjust drawings for non-standard filter baskets and cylinders to fit their equipment.
Clients working in slightly corrosive environments are satisfied with the service life of our 316L perforated filters.
FAQ
Q1: Can you make custom shapes and special hole sizes?
A1: Yes. We produce non-standard perforated metal filters following your drawings or technical requirements.
Q2: Which material fits humid or slightly corrosive working conditions?
A2: 304 works for general non-corrosive environment. 316L is recommended for water, weak acid and salt mist conditions. Duplex steel is for harsh corrosive media.
Q3: What is the maximum working pressure this filter can take?
A3: It depends on plate thickness, hole rate, product diameter and structure. We will give pressure reference once we get your detailed working parameters.
Q4: Can I get samples for testing?
A4: Samples are available. Sample cost and freight will be discussed separately.
Q5: How do I clean stainless steel perforated metal filters?
A5: High pressure water flushing is the common way. Ultrasonic cleaning works well for stuck fine dirt. Avoid hard sharp tools that scratch or deform the plate.
Q6: What is your production lead time?
A6: Regular specifications can be delivered fast. Custom products usually take 15-20 days, depending on order quantity and processing difficulty.
