FAQs of Stainless Steel Mesh Filter Floor Drain
1. What is the structure of a stainless steel mesh filter floor drain?
The core structure includes a 304/316L stainless steel main body, a high-density mesh basket filter, a deodorizing sealing core, and an anti-slip panel. Plumberstar uses an integrated stamping process, so the main body has no weld joints. The mesh basket filter utilizes a multi-layer woven mesh with optional openings ranging from 1 to 5 mm. Filtration efficiency reaches at least 98%, which effectively traps hair and debris. The deodorizing core combines a silicone seal with a gravity rebound design. It seals tightly and helps prevent odors from recirculating up the drain. The top panel is available in brushed or mirror finish. Its anti-slip coefficient is ≥0.8, meeting international safety standards and making it safer to use in wet areas.
2. What is the filtration accuracy and drainage flow of the stainless steel mesh fitter floor drain?
The Plumberstar stainless steel basket filter floor drain is designed to strike a balance between filtration and drainage, making it effective in various real-world situations. The details below show how it does that.
- Filtration accuracy
There are four common mesh options: 1 mm, 2 mm, 3 mm, and 5 mm. The basket is made from 304 stainless steel with a multi-layer woven mesh, utilizing wire diameters of approximately 0.3–0.5 mm.
Each mesh size fits a clear use case.
1 mm is for places like hospitals and food factories, where very fine debris needs to be stopped. 2 mm works best in bathrooms, where hair and fibers are the main issue. 3 mm suits kitchens, catching vegetable scraps and small food waste. 5 mm is used in swimming pools, basements, or utility areas to block stones and larger particles.
Unlike many competitors, Plumberstar offers a wide range of choices, and our woven mesh boasts a tensile strength of ≥500 MPa, enabling it to maintain its shape and resist deformation easily. The filtering performance stays stable over time.
- Drainage flow rate
Drainage capacity is clearly defined by pipe size and is well above standard requirements.
DN50 (2 inch): ≥1.2 L/s, with peak test results up to 1.4 L/s. This is far higher than the 0.3 L/s minimum in GB/T 27710-2020 and better than the typical 1.0 L/s seen in similar products. It works well for bathrooms and balconies, with no water buildup in showers. DN75 (3 inch): ≥2.5 L/s, suitable for kitchens and small pools, where water needs to drain quickly. DN100 (4 inch): ≥4.0 L/s, designed for large pools, basements, malls, and other high-flow areas.
3. How does the mesh fitter floor drain deodorize, anti-blocking, and insect-proof?
The Plumberstar stainless steel net basket filter floor drain uses a triple-protection integrated design that combines deodorization, anti-blocking, and insect prevention in one system. Its key performance features and competitive advantages are outlined below.
- Deodorization performance
The drain is equipped with a food-grade silicone sealing core that combines a gravity-rebound mechanism with a water-seal structure. For dry applications, it also incorporates magnetic adsorption and mechanical closure. The water seal depth is ≥50 mm, and the seal leakage rate is ≤0.01 m³/h, significantly outperforming the typical competitor level of about 0.05 m³/h.
- Anti-blocking performance
A high-density stainless steel basket filter with optional apertures from 1 mm to 5 mm achieves an interception rate of ≥98%, accurately capturing hair, food residues, and other debris. Thanks to an optimized internal flow channel, the effective drainage diameter is about 30% larger than that of many competing products. The basket can be removed without tools in around 30 seconds, making cleaning fast and simple. In real use, the clogging rate is ≤0.1%, far below the industry average of 1%–2%, and even under high-flow conditions, the drain discharges water quickly without pooling.
- Insect prevention performance
Insect control is ensured by a dual physical barrier formed by the filter basket and the sealing core. Compared with the single-layer protection, the smallest mesh size of the basket is only 1 mm, and when closed, the sealing core fits tightly against the valve body with no gaps, delivering 100% insect-blocking effectiveness. This design avoids issues such as insect intrusion after basket damage or leakage through sealing gaps.
4. Can a stainless steel net basket filter floor drain be customized the size?
Plumberstar stainless steel basket filter floor drain offers full-size customization. You can flexibly adjust core dimensions — panel size, inlet diameter, and installation depth. Just match it to your foreign trade order requirements, pipeline specs, or decoration designs.
- Here are the specific customization options. Square panels can be made in any size. The size range is from 50×50mm to 300×300mm. The regular standard sizes are 100×100mm and 150×150mm. Circular panels support customization. The size range is from φ50mm to φ300mm. They work well for special decorative styles, such as invisible floor drains and strip drainage setups. Panel thickness can be adjusted from 3mm to 8mm. Thickened panels (≥6mm) have a bearing strength of ≥ 1.0 MPa. They’re ideal for high-traffic areas like shopping malls and garages, preventing deformation and sinking.
- Inlet diameter customization. Main diameters cover DN50 (2 inches), DN75 (3 inches), and DN100 (4 inches). You can also get special diameters from DN40 to DN150. These adapt to different pipeline flow needs. For example, DN40 suits small balconies, while DN150 is for large pools or basements with high drainage demands. Custom diameters still guarantee great drainage efficiency. A DN150 custom model has a flow rate of ≥6.0L/s, far exceeding national standards. No waterlogging risk at all.
- Installation depth customizationRegular installation depth is 80mm to 150mm. You can customize ultra-thin models (≥50mm) for shallow pipe scenarios after pipeline shifting. Or deepened models (≤300mm) for deep water seal and odor-proof needs. The water seal depth is ≥50mm, meeting the odor control standards of the Ministry of Housing and Construction. For faulty pipeline setups, you can get lengthened floor drain cores. This prevents water from leaking into the mortar layer and causing wall mold.

- Triple protection design (high-precision filtration + silica gel deodorization + anti-skid panel), the anti-blocking, deodorizing, and anti-skid effects are far superior to those of competitors only do basic filtration.
- Strong scenario customization capabilities, with size and material options available, enable customization of up to 300 pieces. The delivery cycle is ≤25 days, making it suitable for small and medium-sized orders in foreign trade. In contrast, competitors generally have a customization threshold of more than 1000 pieces.
8. Can the mesh fitter floor drain handle heavy foot traffic without damage?
Our stainless steel mesh filter floor drain’s resistance to trampling is ensured through a combination of high-strength materials and a reinforced structural design, as outlined below.
Reinforced Structural Design for Impact and Load Resistance:
Mortise-and-tenon welded structure. The stainless steel panel and filter basket are connected using a mortise-and-tenon welding method. This creates a stable, integrated structure that resists deformation and loosening under repeated pressure.
Even load distribution. The reinforced stainless steel panel works together with the internal filter to distribute pressure evenly when stepped on. This reduces point stress and prevents dents or surface deformation.
Secure filter-to-body connection. The tight mechanical connection between the filter basket and the drain body prevents displacement or loosening, even under heavy loads or continuous trampling.
