Frequently Asked Questions

304 stainless steel mesh contains 18% chromium and 8% nickel, providing excellent corrosion resistance for general applications. 316 stainless steel mesh adds 2-3% molybdenum, which significantly improves resistance to chlorides, acids, and saltwater. 316 is ideal for marine environments, chemical processing, and pharmaceutical applications, while 304 is more cost-effective for food processing and general filtration.

Mesh count refers to the number of openings per linear inch. For coarse filtration (particle retention >500 microns), choose 10-40 mesh. For medium filtration (100-500 microns), use 60-120 mesh. For fine filtration (10-100 microns), select 150-325 mesh. Ultra-fine filtration below 10 microns requires 400+ mesh or multi-layer configurations. Contact our technical team with your specific particle size requirements for personalized recommendations.

304 stainless steel mesh prices range from $8-15 per square meter for standard mesh counts, depending on wire diameter and quantity. 316 stainless steel mesh ranges from $12-22 per square meter. Bulk orders above 500 square meters qualify for wholesale pricing with discounts of 15-30%. Custom specifications (special alloys, coatings, or shapes) may incur additional tooling costs.

Yes, we specialize in custom stainless steel mesh manufacturing including filter discs, cylinders, cones, baskets, and pleated filters. We support laser cutting, CNC punching, welding, and edge wrapping to meet your exact specifications. Minimum order quantities for custom shapes typically start at 100 pieces.

Stainless steel wire mesh is used across numerous industries: food & beverage (sugar, juice, coffee filtration), pharmaceuticals (API filtration, sterile processing), chemicals (acid/catalyst filtration), water treatment (desalination, wastewater), oil & gas (well screens, refining), aerospace (hydraulic filtration), automotive (fuel filters), and mining (ore processing). Each application requires specific alloy grades and mesh configurations.

Open area percentage = (mesh opening size² × mesh count²) × 100. For example, a 100 mesh with 0.0045 inch wire has approximately 30% open area. Higher mesh counts have lower open area but finer filtration. Lower mesh counts have higher open area with better flow rates. Our engineering team can calculate the optimal balance between filtration efficiency and flow rate for your specific application.

Standard mesh rolls (304/316, common mesh counts) ship within 3-5 business days from our warehouse. Custom cutting and shaping adds 5-7 business days. Large volume orders (10,000+ sqm) may require 2-3 weeks production time. We maintain inventory of popular specifications to support urgent orders. Express shipping options are available for time-sensitive projects.

Yes, we offer free A4-size samples (20×30cm) for standard mesh specifications. For custom specifications, we charge a nominal sampling fee ($50-100) which is fully credited against your bulk order. Samples typically ship within 2-3 business days via DHL or FedEx. Contact us at [email protected] with your mesh requirements and shipping address.

Our manufacturing facility operates under ISO 9001:2015 quality management system. We provide material certifications (MTC) for all 304 and 316 stainless steel mesh, including chemical composition analysis. FDA-compliant 316L mesh is available for food and pharmaceutical applications. SGS and TUV third-party inspections can be arranged upon request.

Stainless steel mesh can be cleaned using ultrasonic baths, back-flushing with water or solvent, acid pickling for mineral deposits, or high-pressure water jets. Avoid chlorine-based cleaners which can cause pitting in 316 grade. For permanent installations, install pressure differential gauges to monitor clogging and schedule cleaning before flow rates drop below 70% of design capacity.

304 stainless steel mesh can operate continuously up to 800°C (1472°F) in dry environments. 316 stainless steel mesh withstands up to 870°C (1598°F). For high-temperature applications above 900°C, we recommend Inconel or Hastelloy alloys. Actual service life depends on temperature cycling, chemical exposure, and mechanical stress.

Yes, stainless steel mesh provides effective electromagnetic interference (EMI) shielding in the 30MHz-10GHz range. Shielding effectiveness typically achieves 40-80dB depending on mesh count and layer configuration. Faraday cages, RF shielding enclosures, and military-grade applications often use 80-200 mesh stainless steel with copper or nickel plating for enhanced conductivity.

Plain weave has wires crossing alternately (over-under), creating square openings. It is the most common and cost-effective weave style. Twill weave has wires passing over two then under two (2×2), creating stronger mesh with the same opening size. Dutch weave uses thicker warp wires with thinner weft wires, providing extremely fine filtration (up to 5 microns) with high strength.

Use a digital caliper to measure wire diameter at three points and average. For mesh count, count the number of openings in one linear inch using a magnifying glass or mesh counter. Alternatively, use the formula: Mesh count = 25.4 / (wire diameter + opening size). Our quality inspection reports include precise measurements for every batch.

We accept T/T (telegraphic transfer), L/C (letter of credit) for large orders, and Western Union for samples. Standard terms are 30% deposit, 70% before shipment. For orders over $50,000, we offer flexible payment schedules. PayPal is available for orders under $1,000. All prices are quoted in USD FOB Tianjin port.
